AC Line Conditioning

The A-16 is a digital device and is sensitive to sudden spikes and drops in the AC line voltage. Changes in the line voltage from lightning, power outages, etc. can sometimes damage electronic equipment.

To minimize the chance of damage to your equipment from sudden changes in the AC line voltage, you may want to plug your equipment into a power source that has surge and spike protection. Power outlet strips are available with built-in surge protection circuits that may help protect your equipment.

Other options for protection of your equipment include the use of an AC line conditioner or a battery backup system (sometimes referred to as an uninterruptible power supply, or UPS).

Aviom A-16 Personal Monitor Mixing System

Installing the A-16T in a Rack

The A-16T Transmitter is designed to be installed in a standard 19-inch audio equipment rack. This design is both for easy transportation of the unit and for protection.

The unit takes up one standard rack space. Optionally, you can use the unit on a table top or other flat surface such as a shelf.

The rack ears on each side of the unit are designed to support the weight of the A-16T without additional hardware. Each rack ear contains holes for two screws per side.

Always support the unit with four screws.

To mount the A-16T Transmitter, position it in the equipment rack at the desired location. Use standard rack-mounting screws to attach the unit to your rack hardware.

Tighten all four screws firmly, but avoid overtightening.

You may want to use non-metallic washers between the rack-mounting screws and the

A-16T’s finished surface to avoid marring the painted finish on the A-16T Transmitter.

Always allow adequate ventilation for devices mounted in racks. Avoid placing your

A-16T directly above or below other rack-mounted gear that produces high levels of heat.

Channel Labels

For writing channel information or names on the A-16 Personal Mixer label surface or

“scribble strip”, we suggest the using a china marker or other easily removed marking device. A china marker is designed for marking on plastic, metal, glass, wood, and paper. These are available at most office supply outlets. Avoid the use of permanent markers.

Personal Mixer Label Strip

To clean the label writing area on the A-16 Mixer, use a soft clean cloth to remove most types of temporary marking material. For difficult-to-remove types of marking devices, a cotton swab moistened with a drop of rubbing alcohol can be used. Use the minimum amount possible to remove the writing. Be careful not to get rubbing alcohol on the surface of your Aviom products.

What is Category 5?

Category 5 (sometimes referred to as Cat-5) describes a commonly used type of high performance network cabling. It is used mainly for data transmission purposes to connect computers, modems and other devices. A standard Category 5 patch cable consists of four twisted pairs of copper wire terminated by RJ45 male connectors. The cable assembly is used to provide connectivity between any two Category 5 female outlet jacks. A variation, called Category 5e, uses additional twists in the cable to reduce interference in high-speed network applications.

The RJ45 connector looks similar to the connectors found on a telephone system, only larger. The twisting of the wire pairs helps to shield the cable from unwanted interference from electrical fields or radio interference (sometimes referred to as “RF”). Cat-5 cabling supports frequencies up to 100 MHz and speeds up to 1000 Mbps.

Category 5 cables

Cables Used in the Aviom System

The Category 5 cables used with your Aviom system are interchangeable with any standard Category 5 (or Cat 5e) cables. If you need a longer cable for a particular application, any computer store should be able to supply you with an appropriate cable.

A qualified technician should be able to build custom cables to any length (up to the maximum of 500 feet between components).

For fixed or permanent installations, you have the option of running Category 5 cables inside walls and terminating them with readily available wall panels that include the

RJ45 jack.

Note: When purchasing Category 5 cables, be sure to buy only standard Cat-5 cables, not those sold as crossover cables. A crossover cable is used for file transfer between two computers. It is not compatible with your Aviom equipment.

Aviom A-16 Personal Monitor Mixing System

Cable Lengths

Category 5 cables used with the A-16 Personal Monitor Mixing System can be up to

500 feet (approximately 150 meters) in length. The maximum cable length specification applies to the cable connected between the A-16T Transmitter and the first A-16

Personal Mixer in your system as well as for cable runs between each additional A-16

Personal Mixer unit in your system.

Pre-made cables in a variety of lengths and colors are available at most computer outlets. Cables can be extended by using a simple passive device called an inline coupler to add length to existing cables (as long as you do not exceed the specified maximum cable length). If you need a longer cable on occasion, this is a simple solution. Inline couplers are available at most computer outlets.

About A-Net

Aviom’s A-Net is a high-speed data transmission protocol. It is capable of sending and receiving high-quality audio using readily available Category 5 cables. The A-Net technology is a proprietary system developed by Aviom.

A-Net is based on Ethernet, a Local Area Network (or LAN) technology. This provides

A-Net with a mature and robust base on which to build.

As used in your A-16 Personal Monitor Mixing System, the A-Net signal carries sixteen channels of digital data from the A-16T Transmitter to each and every Personal

Mixer connected to the system.

Some of the benefits of using A-Net to transmit digital audio are:

• No latency

• No ground loops

• Easy cabling using readily available components

• An unlimited number of Personal Mixers can be used in a system

• Ease in spanning long distances between system components

Note: While the Category 5 cables and connectors used on your Aviom products look like typical computer network connections, do not connect computers, routers, or other home and business networking equipment to your Aviom products.

Aviom A-16 Personal Monitor Mixing System

Power Supplies

Your Aviom product uses a DC power supply that has a two-prong power cord. The prongs on the power supply are identical, meaning that there is no need to orient the plug in a specific direction in the power outlet. Some products with two-prong power cords have polarized plugs that can only be inserted into an electrical outlet one way.

The power supply that ships with your Aviom product is a universal switching type.

It is capable of working with voltages from 100 to 240 volts AC. This means that a separate power supply is not needed to use the products with the power systems found in most countries. You may need plug adapters to use the power supply with the AC outlet plug shape variations used throughout the world.

Should you need to replace the power supply that came with your product, we recommend using only a power supply that meets the following specifications.

Navigating the System

This section explains the basic layout of your new Aviom products. The diagrams on the previous pages can be used as a quick visual guide to the location of the basic components of the Personal Monitor Mixing System.

The A-16T Transmitter

Front Panel

The front panel of the A-16T contains the Channel information, Link switches, Signal

Present LEDs, Clip LEDs, Power indicator, Input Level switches, and the A-Net output connector.

Channel LEDs

The numbered Channels on the A-16T front panel correspond to the sixteen inputs on the rear section of the A-16T. They are grouped together in pairs — Channels 1 and 2,

Channels 3 and 4, etc. Each Channel contains two LEDs, one showing that there is an audio signal present, and another used to indicate that the input to a channel is causing audio clipping. Signal and Clip LEDs appear directly beneath the Channel numbers.

The lower LED, marked Signal, will light as long as an audio signal of at least -40dB is present on the channel. It provides an easy way to confirm that audio is indeed passing into—and being processed by—the A-16T.

The upper LED is marked Clip. It will light if a signal reaches a point that is within

3 dB of full scale (0dB). In general, you want to operate the system so that the Clip

LED lights only occasionally. If the LED is on constantly, you should either lower the volume of the source audio coming into the A-16T or try different Input Level settings.

Input Levels

The A-16 Personal Monitor Mixing System has been designed to accept a wide range of professional and semi-professional audio levels. There are four Input Level gain

14 15

Aviom A-16 Personal Monitor Mixing System

14 settings available. Changes to the input level on the A-16T front panel affect a pair of channels at a time.

The four levels are +22dB, +4dB, 0dB, and -10dB. To select the proper Input Level setting, choose the Input Level position that most closely matches the output of your audio gear. Here are some examples to be used as a guide:

• Use the +22dB setting for the hottest signals such as those coming from professional broadcast equipment, tape decks, and some digital audio workstations (DAWs).

• The +4dB setting is the best choice for most professional audio gear such as mixing boards, microphone preamps, effects processors, etc.

• Try the 0dB setting for musical instruments such as keyboards and drum machines.

• The -10dB setting is appropriate for consumer audio devices such as CD players and MP3 players. Also, semi-pro audio gear should use the -10dB setting. (In many cases those devices use RCA jacks for audio input and output.)

Check the specifications of your audio gear if you are unsure about its output level.

Although you won’t harm the A-16T or your audio devices by using an incorrect level setting, you do want to avoid distorting the audio that passes through the A-16 system and eventually on to your monitors.

In general, you need to check the A-16T front panel Signal and Clip LEDs when initially setting up your audio system and choosing level settings. If your -10dB device outputs a hot level, it may be necessary to adjust the Input Level switch to avoid clipping. In this example, moving the switch to the 0dB setting should provide a strong signal without distortion.

The Link Switch

The A-16T Transmitter provides an easy solution for stereo input sources such as keyboards, mixer sub-groups, drum machines, CD players, effects device outputs, etc.

The Link switch is used to turn a pair of adjacent channels into a stereo channel that can be controlled as a single source on the Personal Mixers.

15

Aviom A-16 Personal Monitor Mixing System

There are eight Link switches on the front panel of the A-16T. They can be used in any combination, as your needs require. The Link switch is located between two channels—one odd and one even. Links always affect adjacent channels (for example, channels 1 and 2, channels 13 and 14, etc.).

The default setting, with the Link switch to the left, allows independent control of each input channel from the A-16 Personal Mixers. To link channels together as a stereo input, move the Link switch to the right. (Moving the switch to the Link position causes all Personal Mixers connected to the system to instantly update their channel status.)

Some things to keep in mind about linked channels:

• Linking channels affects all A-16 Personal Mixers connected to the system.

• Any combination of stereo and mono channels can be used.

• If you want to control two input channels as a stereo source, they must be connected to an odd and even pair of channels, as indicated by the graphics on the A-16T front panel.

• Changes to the Link status can be made on the fly, with audio running through the system.

• All A-16 Personal Mixers will instantly update their channel status if the

Link switch position is changed for any channel pair.

• The Link status is not saved when you create a Preset.

• Changing the channel link status will affect Groups you have created in some cases.

Power and A-Net

The right side of the A-16T Transmitter also contains the Power LED. This indicator shows that power is connected to the unit. It does not indicate, however, that a valid

A-Net signal is being generated.

The A-Net output jack is used to connect the A-16T to the first A-Net compatible device in your monitor system. Use any standard Category 5 cable to make the connections. Remember that the maximum cable length is 500 feet (150 meters).

When a proper A-Net connection between the A-16T Transmitter and a Personal Mixer exists, the A-Net Active LED on the Personal Mixer will light.

16 17

Aviom A-16 Personal Monitor Mixing System

16

The A-16T Rear Panel

On the rear of the A-16T Transmitter you will find the power connector, the sixteen audio inputs, and the sixteen Thru jacks.

Signal routing into and out of the A-16T Transmitter has been designed to be extremely flexible, allowing the A-16T to integrate into virtually any audio environment.

Power Connector

Your A-16T Transmitter comes with a switching-type power supply. This type of power supply can be used with a wide range of AC wall current outputs, meaning that you do not need to replace the power supply if the unit will be used in different countries throughout the world where current voltages are different. (You may, however, need plug adapters to allow the power supply to be connected to wall outlets internationally since many countries use different physical plug layouts for their power systems.)

Channel Input Jacks

The rear panel of the A-16T Transmitter contains sixteen Input jacks (labelled In).

These jacks can accept balanced or unbalanced signals on 1⁄4-inch plugs.

Balanced signals (sometimes referred to as TRS, for Tip, Ring, and Sleeve) are found on many professional audio devices. The 1⁄4-inch connector used for balanced audio wiring has three conductors: the tip, the ring, and the sleeve. It is the same connector found on most stereo headphones, for example. The balanced wiring system is ideal for keeping noise out of the audio signal from sources such as radio interference (sometimes called “RF”).

Unbalanced audio signals are found on many keyboards, effects processors, etc. Only two connectors are used, the tip and the sleeve. A standard musical instrument or guitar cord uses this configuration, for example.

Channel Thru Jacks

The Thru jacks on the A-16T provide the user with an exact copy of the signal plugged into the In jack just below it. This can be used as a way to insert the A-16T Transmitter into a signal chain without giving up audio patching flexibility.

The Thru jacks have other uses as well. While a direct output from a mixing board is the most straightforward way to connect audio from your mixer to the A-16T, some

17

Aviom A-16 Personal Monitor Mixing System

mixing boards do not have this signal routing option available. In this case, the mixer’s insert points (sometimes referred to as an effect insert send and receive) can be used instead. When using a mixing board’s insert points to get monitor signals into the A-16T, the Thru jack can be used to complete the insert send/receive loop used by most manufacturers. Additional information about patching and connecting systems appears later in this document.

The A-16 Personal Mixer

This section describes the controls, modes, and functions of the A-16 Personal Mixer.

The basic components of the front panel include:

• Sixteen lighted Channel buttons (they are also the Preset select buttons)

• Channel label strip

• Recall button

• Group configuration and edit button

• Solo and Mute buttons

• Pan and Volume knobs

• Bass and Treble tone controls

• Master Volume control

Group Mode — Used when creating Groups or editing existing Groups.

This is activated by pressing the

G

ROUP

button. The Channel Select buttons are used to add or delete Channels from a Group.

Solo Mode — When the

S

OLO

button is pressed, the selected Channel (or

Group) is audible while the rest of the mix is muted.

Save Mode — This mode is activated by pressing and holding both the

R

ECALL

and G

ROUP

buttons. When both buttons are held down, the Save

Mode is active. Pressing any numbered button while still holding this button combination will save your current mix to that Preset location.

Note: A Preset is saved when the numbered button is released.

Global Controls

The three knobs in the upper right section of the A-16 Personal Mixer affect your mix volume and tone directly. The Bass, Treble, and Master volume controls are always active, regardless of the selected Preset.

Tone Controls

Use the Bass and Treble controls to change the overall balance of bass or treble frequencies in your mix. These controls affect the entire mix, not the individual Channels.

The default position for the

B

ASS

and T

REBLE

knobs is at 12 o’clock. To add more low frequencies to your monitor mix, turn the

B

ASS

knob to the right of the 12 o’clock position. To remove lows, turn the knob counterclockwise past the center. To change the high-frequency content, follow the same procedure; turn the

T

REBLE

knob right to add highs, left to diminish them.

Master Volume

The overall system volume is controlled by the

M

ASTER

volume control. This is an analog-style control. Turn it counterclockwise for a full off setting. As a general suggestion, start with the Master volume knob at a low setting, about 9 or 10 o’clock to start. Raise the volume slowly from that point to a comfortable level.

Note: Always use caution when adjusting any audio system component to avoid potential hearing damage.

Button Behaviors

There are various combinations of lighted and unlighted buttons on the A-16 Personal

Mixer. Here is an overview:

• Channel buttons have two LEDs, an upper and lower. The upper button is red and indicates that the Channel is selected. The lower button is yellow; it indicates that the Channel is muted. Channel buttons will light solid or flash.

• The

R

ECALL

button has one red LED. It flashes when the R

ECALL

button is pressed, indicating that you can now select a Preset by touching any numbered button.

• There is one LED in the

G

ROUP

button. When the G

ROUP

button is pressed, the LED flashes. This indicates that you can now build or edit a

Group.

• The

R

ECALL

and G

ROUP

buttons will both flash when held down simultaneously. This is the Save Mode, as indicated by the connecting graphic above the two buttons on the front panel.

• When a Preset is saved, all sixteen Channel buttons will flash briefly to confirm the Preset save operation.

• The

S

OLO

button has one LED. It will light when pressed, indicating that the selected Channel or Group is now being auditioned with all other

Channels being muted.

• The

M

UTE

button has no LED in it. Pressing the M

UTE

button with a

Channel selected will cause the Channel’s lower (yellow) LED to light.

20 21

Aviom A-16 Personal Monitor Mixing System

There is also one special button combination, the

R

ECALL

button followed by the M

UTE

button. When used together this combination serves a twofold function:

• If there is a sudden change in the audio volume coming through the monitor system, this button combination silences all audio channels instantly.

• When starting from scratch to create a mix, use this function to set all sixteen channels to zero volume and all pans to the center settings.

All Volumes Zero

Note: The text on the right side of the Personal Mixer reads In Recall Mode All

Volumes Zero as a reminder that this function is always available.

Making Changes to Channel Settings

The A-16 Personal Mixer behaves in a similar manner to many popular digital mixers.

A simple convention is used: to make a change to a Channel, first select it. Then the

Channel is available for editing.

On the Personal Mixer you can change

• Volume

• Panning for mono channels

• Spread for stereo channels

• Mute status

• Grouping

In addition to these changes, you can use Solo Mode to audition your edits to a

Channel while all other Channels are temporarily silenced.

Volume and Pan Control

When you change the volume of a Channel on the Personal Mixer, the LEDs in the

Volume section of the mixer surface will indicate the level in real time. There are twelve LEDs in the Volume indicator, each capable of displaying two levels, for a total of twenty-four visible lighted steps.

When a Channel is selected, the current volume is instantly indicated on the LEDs.

When no LEDs are lit, Channel volume is at its minimum setting.

21

Aviom A-16 Personal Monitor Mixing System

Pan and Volume Controls

To make changes to a Channel:

• Select a Channel by pressing its numbered button—the upper LED will light.

• Rotate the

V

OLUME

knob to the right to increase the volume, to the left to lower the volume

• While the Channel is still selected, you can also change the Pan setting.

Rotate the

P

AN

knob left or right to change the position of the Channel in the stereo field.

Pan LEDs

The Pan indicator is made up of five LEDs. The center LED is green. The LEDs on either side of center are red. As you turn the

P

AN

knob, the LEDs will light in various combinations to provide the maximum number of position indicators with the fewest number of lamps. At either end of the display only one LED will be lit to indicate that the Channel is panned full left or right.

When using linked channels (stereo inputs), the LEDs light in different patterns, using a pair of LEDs on either side of the display to indicate the width of the stereo field.

When the stereo image has been collapsed to mono, only the center green LED will be lit. In this case the stereo input will be heard as mono.

Using Solo Mode

To listen to the Channel you’re editing without hearing the rest of the current mix, press the

S

OLO

button. Make any necessary changes to the Channel. When finished, press the

S

OLO

button again or select any other Channel. Both methods will automatically exit Solo Mode and return you to your current mix.

Note: The status of Solo Mode is not saved with a Preset.

Muting a Channel

While creating a mix, any Channel or combination of Channels can be muted. Unlike the Solo Mode, the changes you make with the

M

UTE

button can be saved as part of a

Preset.

button.

Personal Mixer Rear Panel

On the rear of the Personal Mixer you will find the A-Net connectors, the power supply input, and the audio output.

A-Net Connectors

There are two A-Net connectors on the rear of the Personal Mixer.

The A-Net In jack accepts

• the A-Net signal coming from the A-16T Transmitter if the Personal Mixer is the first Personal Mixer in the system, or

• the A-Net signal coming from the Out jack of another Personal Mixer

The A-Net Out jack is used to connect another A-Net device. This will send the same sixteen audio channels being processed by the A-16T Transmitter to the additional device so that another unique monitor mix can be created. An unlimited number of

A-Net devices can be connected in series using this method.

Aviom A-16 Personal Monitor Mixing System

Audio Outputs

The audio outputs on the rear of the A-16 Personal Mixer can be used with headphones, in-ear monitors, powered speakers, or any other device that can accept a line level audio output. Stereo, dual-mono, and mono outputs are available by using the appropriate cables

Stereo

The TRS outputs on the Personal Mixer are stereo. Any pair of stereo headphones can simply be plugged into the jack.

To connect a set of stereo speakers (studio monitors or stage speakers), use a stereo to dual-mono adapter to split the stereo signal into separate left and right mono signals.

Then connect a standard mono cable to the audio input of the left and the right amplifier for the speakers.

Mono

To use a mono amplifier, powered speaker, etc., connect a standard audio interconnect cable (tip and sleeve “guitar cord” type) from the audio output on the Personal Mixer to the audio input on your mono device.

To use a mono input on a device that has an XLR input connection, you need to use a cable that has a tip-sleeve 1⁄4” jack on one end and an XLR on the other. Using a tipring-sleeve 1⁄4” jack to XLR cable will cause the left and right channels to be summed, resulting in a loss of level.

To make a custom adapter cable using a TS Jack

Quick System Setup

For those who can’t wait to try their new product (or for those who hate reading manuals) follow these quick setup instructions to get up and running in no time.

Refer to the detailed setup and usage instructions later in this document for additional information.

Start with all devices turned off. When all power and audio connections have been made, you can then power up all the components in your system.

AC Power Connection

Both component parts of your Personal Monitor Mixing System use separate external power supplies.

• Connect the power supply to the 18-24 VDC Power jack on the rear of the

A-16T Transmitter unit.

• Plug the power supply into an available AC power outlet.

• Connect the power supply to the A-16 Personal Mixer unit.

• Plug the power supply into an available AC power outlet.

The Personal Monitor System will be in its “on” state as long as it is plugged into a working electrical outlet.

No on/off power switches are included on the A-16 System. If you would like to control the power state of your units, simply connect the power supplies to a power strip with an on/off switch. Use that as a system power switch.

System Interconnections

A single Category 5 cable is required to connect each A-Net compatible device in your system.

Connect a Category 5 cable from the front panel A-Net jack on the A-16T Transmitter to the A-Net In jack on the first Personal Mixer.

Connect additional A-16 Personal Mixers with a single Category 5 cable from the

A-Net Out jack on the first Mixer to the A-Net In jack on the next Personal Mixer.

(Repeat this process for each additional Mixer unit in your system.)

Aviom A-16 Personal Monitor Mixing System

Audio Connections — Inputs

The Aviom A-16 Personal Monitor Mixing System is designed to work in a wide variety of audio situations. For complete setup information, refer to the detailed instructions later in this document.

For the purposes of this quick startup guide, a single audio setup example will be used.

Since many mixing boards provide direct channel outputs, we’ll use that output for example purposes.

If you have a mixer without direct outputs, you can substitute audio coming from any available output of your mixer. That includes the main outputs, bus outputs, aux sends, or insert points.

Connect the direct outputs from your main mixing board channels to the A-16T

Transmitter’s inputs. For simplicity, connect the channels in an easy to remember order. If the lead vocal is plugged into Channel 1 of your main mixing board, connecting it to Input 1 on the A-16T makes it easy to check connections.

For illustration purposes, let’s assume that you have eight audio signals connected from your main mixing board to the A-16T, and that they are plugged into Inputs 1 through 8 on the rear panel of the A-16T.

A-16T Front Panel Settings

For the basic setup example, set all the Input Level switches on the front panel of the

A-16T to the 0dB setting. Next, check that all Link switches are in the left position

(meaning that the channels are not linked). The examples will assume that you are using mono audio signals.

Audio Connections — Outputs

Plug headphones, powered floor monitors, spot monitors, or in-ear monitors into the A-

16 Personal Mixer’s Phones/Line output jack on the rear panel of the Personal Mixer.

Before powering up the system, turn the Master volume control on the Personal Mixer to its minimum setting (full left) to ensure that unwanted high-volume audio is not accidentally sent into your monitors when the system is powered up. The Master volume control is the one in the upper right section of the Personal Mixer, next to the Bass and

Treble controls.

26 27

Aviom A-16 Personal Monitor Mixing System

Labeling the Channels

The A-16 Personal Mixer has a convenient label strip right on the front panel.

Use a china marker (sometimes called a “grease pencil”) to write the name of the instrument or audio source appearing on each Channel’s label area.

Optionally, you could also write a performer’s name on the A-16 label strip marking area to identify Channels.

Use only non-permanent marking devices on the label surface to avoid permanently marring the surface. Do not use permanent marker to write on the label surface.

Powering Up

As when powering up any audio gear, it’s best to power up all system components in the safest possible order to minimize the risk of damage to system components and your hearing. Start by turning on devices such as mic preamps, mixers, keyboards, and effects processors. Follow this by turning on power amps, or anything that applies power to speakers, headphones, etc..

In the case of the Personal Monitor Mixing System, you should power up your main audio mixer, effects devices, and keyboards first. Follow this by powering up your

A-16T A-Net Transmitter and then all connected A-16 Personal Mixers.

Lastly, turn on any power amps, powered monitor speakers, in-ear monitors, etc. that are part of the monitor system.

Basic Navigation

When the system is powered up, Preset 1 is automatically selected. On the Personal

Mixer, one Channel is always selected for editing. You can tell that a Channel is selected because the upper LED in its button is lit.

The sixteen Channel buttons have two LEDs in each, an upper and a lower. The red upper LED indicates that the Channel is selected; you can change its volume and panning. You can also solo or mute the track using the dedicated

S

OLO

and M

UTE

buttons on the Personal Mixer surface. More on that later.

The upper LEDs will also light in combination if a track is linked or is part of one of the three available Groups. (More info on Groups appears later in this quick startup section.)

The lower yellow LED in each Channel button indicates the Channel’s mute status. A lit LED indicates that the Channel is muted. Any number of Channels can be muted.

27

Aviom A-16 Personal Monitor Mixing System

Preparing to Make a Mix

Set the global tone controls—

B

ASS

and T

REBLE

—to about 12 o’clock. This is the default EQ setting; no boost or cut is applied to the audio mix.

Set the

M

ASTER

volume knob on the Personal Mixer to a low setting, about 9 or 10 o’clock should be safe. Send audio into the system; this could be the band playing live or audio from a tape deck or other multi-track audio device. Raise the levels to a comfortable level after you have audio playing through the system.

Mixing

Start creating a monitor mix by selecting the first Channel you want to hear.

Follow these steps:

• Press the desired Channel button — its upper red LED will light.

• Turn the

V

OLUME

knob clockwise to raise the volume of the selected

Channel until you hear it in the monitors. You should see the volume changes you’re making reflected in the Volume LED indicators. More

LEDs lit indicates higher volume.

There are twenty-four visible volume steps available in the Volume LEDs. Each LED lights at two levels—one at half brightness, the other at full brightness.

The procedure for setting the pan position for a Channel is similar. Once a Channel is selected, you can turn the

P

AN

knob left or right to move the Channel in the stereo field. Your changes will be reflected in the Pan LEDs. Changes will be heard immediately in any speakers or headphones connected to your Personal Mixer.

Note: If you have connected the output of the Personal Mixer to a mono audio system or speaker, pan position is irrelevant.

A Channel is playing in the center of the stereo field when only the center (green) LED is lit. As you turn the

P

AN

knob, the Pan LEDs will light in various combinations to indicate the pan position.

Continue this process of setting volume and pan until all the Channels have been added to the mix.

At this point you should have a basic mix playing in your monitors. You can continue to make changes in real time as your needs require. Remember that changes to Channel volume and pan setting affect the selected Channel only. The selected Channel always has its red LED lit.

Saving Your New Preset

It’s important to remember that your mix is not saved if you should power the system down unless you store the mix as a Preset. You need to save a Preset to a memory location to be able to recall it later. The Channel buttons serve as memory location buttons when in Save mode.

To save a Preset:

• Hold down the

R

ECALL

and G

ROUP

buttons, found in the upper left side of the Mixer surface.

• While still holding the

R

ECALL

and G

ROUP

buttons, press the Channel button (1 through 16) corresponding to the memory location where you want the mix to be stored.

• Release the Channel button to store a Preset; you will see all the Channel

LEDs flash in sequence as confirmation of the save operation.

• Release the

R

ECALL

and G

ROUP

buttons after selecting a location.

If you want to store the same mix to multiple memory locations, you can press memory location buttons as needed while the

R

ECALL

and G

ROUP

buttons are being held down.

A copy of the mix will be saved to each memory location.

What Gets Saved

When you save a Preset the following information is saved:

• Channel volumes

• Channel pan settings

• The mute status of all Channels

• Channel Groups (up to three) and Group volume settings

• The current active Channel, linked pair, or Group

Tip: By selecting a Channel prior to saving a Preset you can always have your favorite Channel ready for real-time editing when the Preset is recalled.

Aviom A-16 Personal Monitor Mixing System

Connecting Audio

The are many ways to get audio into the A-16 for processing. Depending on your application—studio, stage, etc.—the types of signals and equipment available will vary. This section will give examples of some typical setups that you can modify to suit your individual needs.

Connections on the A-16T Rear Panel

There are two rows of connectors on the rear of the A-16T Transmitter. They are marked In and Thru, but are much more flexible than the simple labels may lead you to believe.

The connections on the A-16T can accept balanced or unbalanced 1⁄4-inch cables.

The system can accept a wide variety of signal levels.

The audio design of the A-16T allows you to add the system at virtually any point in your audio system. It can accept audio coming from:

• Mixing board direct outputs

• Mixing board insert sends only

• Mixing board insert send and return loops

• Line output from mic preamps

• Line outputs from keyboards and other music devices

• CD players

• Tape decks

• Digital Audio Workstations (DAWs)

• Effects processors

• Video decks, cameras, etc.

Signals sent into the A-16T Transmitter can be at any level, from semi-professional and home recording gear, studio devices, and broadcast equipment.

Connecting a Mixer

As mentioned above, almost any line level audio output can be used with the A-16T.

Depending on the topology of your particular mixer, some or all of the following signal types could be available.

Direct Output

A direct output is typically found at the channel level. That is, each channel on the mixer has its own direct output jack. This type of output sends an exact copy of the audio signal present in each channel out of the mixer without interrupting the signal being sent to the main part of the mixer. This layout is ideal for use with the A-16.

30 31

Aviom A-16 Personal Monitor Mixing System

30

If your mixer has direct outputs available, then a cable from each channel that needs to be sent to the monitors is connected to the Transmitter inputs. A maximum of sixteen direct outputs can be plugged into the Transmitter unit.

If you have more than sixteen direct outputs to be monitored, then some of the channels will need to be sub-mixed. This can be accomplished on most consoles by using a bus output, described below.

Bus Outputs

A bus output is typically used to route audio signals to a recording device or to control the volume of a group of channels from a single fader. Most mixers equipped with bus outputs have fewer bus outputs than channels. Four, eight, or sixteen bus outputs are common mixer configurations.

To use a bus output with the A-16T, the individual channels in your mixer need to be assigned to the desired bus output. This is usually done with a selector button located somewhere within each channel strip. Assigning a channel to a bus output does not remove the signal from the main mix. (Some mixers do allow the option, however.) Specific instructions about how to use your particular mixer in this case are beyond the scope of this document. Consult your mixer’s documentation to learn more.

With a channel assigned to a bus output, you can then control the level of the bus independent of the other levels on the mixer. In fact, if you assign multiple channels to a bus output, this acts as a sub-mixer, combining the audio from all assigned channels into one signal. The individual channel level fader is used to set the relative balance of all channels assigned to the bus.

As an example, you could assign all the channels of the main mixer devoted to drums to a bus. As mentioned previously, the relative mix of all the components of the drum sound would remain the same; the levels are based on the individual channel’s level settings. By sending all the drum channels to a bus, the entire drum kit sound can be raised or lowered in volume from a single fader. (By using two bus outputs a stereo drum sub-mix with panning can be created. More on this below.)

The same theory extends to the operation of the A-16. If you send the sub-mixed drum sound in the example above from a console bus output to the A-16T Transmitter, then each Personal Mixer in the system has a single channel devoted to the drums. Each performer can control the amount of drums in his/her mix with a single knob. He/she cannot, however, change the relative balance of the drums that make up this mix (more snare, less cymbals, etc.). This change would need to be made at the main mixer, and would affect the balance in all connected A-16 Mixers.

31

Aviom A-16 Personal Monitor Mixing System

You can extend this idea further to create a stereo drum mix. This requires that the drums be assigned to two bus outputs, usually consecutive numbers such as 1 and 2,

3 and 4, etc. The pan (or left/right balance) from the drum kit is then set by using the mixer’s Pan knobs. To get the floor tom into only the right speaker, for example, its pan knob should be turned to the fully clockwise position.

The bus output idea can be combined with direct outputs as needed. This could be useful if you wanted to have individual control over the band’s instruments, but also be able to turn up or down all background vocals from four singers from a single knob.

Aux Sends (Effects Sends)

An Auxiliary Send (or Aux Send for short) is typically used on a live or recording console to send the sound from a channel into an effect device such as a reverb. Using a dedicated set of knobs found in each channel strip, each channel can have a different amount of the effect applied as needed.

An Aux Send does not have to be used exclusively with effects, though. You can think of an Aux Send as another mini mixer; it functions in a similar manner to a bus output.

It is used to pass the audio signals from the console to another destination. You can use any combination of audio sources with the A-16 to create a monitor mix.

The method for using an Aux Send to create a monitor mix is similar to that described for using a bus output. Most consoles have from two to eight Aux Sends. So, the number of independent audio signals that can be sent to the A-16T Transmitter via Aux

Sends will depend upon the design of the mixing console you are using.

Insert Send/Return Points

The insert loop on an audio mixer is typically used as a means of extending the processing capabilities of the mixer on a channel-by-channel basis. An effects device such as a compressor can be added to the channel so that only that specific channel is affected.

An insert on a mixer consists of a Send and a Return. The Send is used to get the channel’s audio into the effects processor. The processed signal coming from the effects device goes back to the console via the Return path.

The physical jack layout of an effect Send/Return loop on a console varies depending on the model and manufacturer.

TRS Inserts

Some consoles use a single jack to perform both send and return functions. In this case the jack would use tip-ring-sleeve (TRS) wiring, with one of the signal wires performing the Send function, the other being used for the Return. Both Send and Return share the common ground wire. For TRS inserts, it is common to use a “Y” cable, one that has a TRS plug on one end and then a split into two mono tip-sleeve cables on the

32 33

Aviom A-16 Personal Monitor Mixing System

32 other.

Using a TRS insert, the effects device would have the Send cable plugged into its Input and the Return cable plugged into its Output. This wiring completes the loop without interrupting the audio being played though the console.

Console TRS

Channel Insert

Signal flows from the console into the effect device and back into the console

To use the A-16T Transmitter with this insert layout, both the In and Thru jacks on the

Transmitter are used. The main console’s Insert Send should be plugged into the In jack on the Transmitter. The Thru jack on the Transmitter is used to return the signal to the console, completing the audio loop. In this case the A-16T acts like an effects device, but it has no audible effect and does not change the audio signal in any way.

Note: There is some variation in the send/return insert wiring on consoles. Some manufacturers use the TRS tip connection for a send function, while others use the ring connection. Consult your console’s documentation.

Discreet Insert Send and Return Jacks

If a console uses separate jacks for Send and Return functions, the cable connections are much more obvious. The Send from the Insert point on the console is connected to the A-16T Transmitter In jack. The Thru on the A-16T is connected to the Return jack on the console to complete the loop.

Aviom A-16 Personal Monitor Mixing System

Line Level Devices

In addition to connecting a traditional mixing console, there are numerous other audio sources that can be used with the Personal Monitor Mixing System. There is no requirement that your audio sources be connected to a mixing console first.

Using some creative patching, you’ll find numerous uses for the Personal Monitor

Mixing System. Here are a few examples:

• Connect a CD player’s stereo outputs to two inputs on the Transmitter.

Singers can rehearse to a backing track while still controlling their vocal balance in the monitors

• Patch a drum machine output into the A-16T to provide a click track.

• If a keyboard player has multiple keyboards being mixed by a dedicated keyboard line mixer, that mixer’s outputs can be connected to the A-16T.

• Connect outputs from stereo guitar processors or amp simulators.

• Virtual drums can be connected directly into the A-16T. Add in outputs from keyboards and guitar amp simulators, and a band can rehearse silently without a mixer.

34

Mixing

The process of creating a monitor mix using the Personal Monitor Mixing System is similar to the process used to create a front of house mix. As mentioned in the Quick

Setup tutorial section, the Personal Mixer interface makes it easy to jump right in and create your first mix within minutes of connecting the system for the first time.

Mixing involves setting pan, volume, and mute status for each Channel, and then saving this setup as a Preset so that you can recall your custom mix later.

The user interface is quite simple to understand. As with many digital mixers, the A-16

Personal Mixer has many Channels, but only one set of controls that are shared by all the Channels. A Channel is selected by pressing one of the numbered Channel buttons on the Mixer’s front surface. When a Channel is selected, the red LED in the Channel’s button will light to indicate that it has been selected and is ready to be edited.

The procedure to edit a Channel involves only two steps:

• Select the Channel you want to change.

• Edit the volume, panning, or mute status

That’s it. Each Channel can be edited by using the same simple steps.

The Editing Interface

When you turn the

V

OLUME

knob clockwise to raise the volume of the selected

Channel, the volume is reflected in the Volume LED indicators. There are twenty-four visible volume steps available in the Volume LEDs. Each LED lights at two levels, first at half brightness, then at full brightness. More LEDs lit indicates higher volume.

The pan position for a Channel can be changed with the

P

AN

knob. Turn it left or right to move the audio in the stereo field. Your changes will be reflected in the Pan

LEDs. The Pan LEDs are used to indicate the left-center-right location of the selected

Channel. The Pan LEDs have a green middle LED to indicate the center position in the stereo field with red LEDs on the sides to indicate left or right positions. Changes will be heard immediately in any speakers or headphones connected to your Personal

Mixer.

Making Changes to a Mix

Once you have a basic monitor mix, you may want to make changes to fine tune the settings for the individual Channels. This is as simple as selecting the Channel and then adjusting the

V

OLUME

and P

AN

knobs as required.

35

Aviom A-16 Personal Monitor Mixing System

When you select a Channel by pressing its corresponding numbered Channel button, the current settings for channel volume and panning are indicated instantly in the

Volume and Pan LED readouts. When a Channel is selected, you can always make real-time changes to its settings.

Note: Remember to save your new mix to a memory location before turning the system off.

Linking Channels

For stereo input sources such as keyboards, drum machines, CD players, main mixer submixes, etc., the A-16T provides a convenient method of controlling these two-channel sources. It’s called a Link. A Link is simply two Channels working together as one to process a stereo input.

Linking two Channels is done from the front panel of the A-16T Transmitter. Each pair of inputs has a corresponding Link switch. When the switch is positioned to the left, the two Channels are independent. When the switch is moved to the right, the Channels become linked. Only adjacent Channels can be linked (Channels 1 and 2, Channels 3 and 4, etc.).

When Channels are linked, they act as one source on the A-16 Personal Mixer. When you select either of the two linked Channels on the Mixer, both LEDs will light up, indicating that they are linked. Volume changes affect both Channels simultaneously.

Channels that are linked at the A-16T Transmitter will appear linked on every Personal

Mixer connected to the system. You can link or un-link Channels as needed, even while audio is running through the system. All connected Personal Mixers update immediately.

The Spread Control

When two Channels are linked, they no longer have separate pan controls. With the

Channel link comes a new feature, called Spread. The Spread control varies the stereo image of the two linked Channels from full stereo to mono. This allows you to position stereo sources in your mix by controlling the width of the stereo image.

Spread changes the panning of the left and right Channels simultaneously. Instead of having two Channels panned 100% left and right, Spread allows the Channels to be panned to 60% left and right, for example.

The Effect of the Spread Control

Spread turns this: into this, for example

When you adjust the Pan control with a stereo-linked Channel selected, the Pan

LEDs show the width of the stereo spread that is currently set. Multiple LEDs light to indicate the compression of the image from full stereo to mono.

The Mute and Solo Functions

Solo a Channel

While working with a mix, you may want to listen to a particular Channel by itself to check a part, locate or solve a problem, select a pan location, etc. To do this you can use the Solo mode. The Solo mode lets you listen to the selected Channel alone without disturbing the rest of the mix.

Solo mode works on the currently selected Channel or Group. To use Solo mode, first select the Channel you want to hear alone. Its red button LED should be lit. Now press the

S

OLO

button, found in the pair of buttons in the upper right corner of the Personal

Mixer. The Channel is now heard solo.

You can make changes to volume and panning when a Channel is in Solo mode. All changes happen immediately. Consider Solo mode as a temporary state only. You cannot save a Preset with a Channel in Solo mode.

Only one Channel, linked pair (or Group) can be in solo at a time. To exit Solo mode, simply select another Channel or press the

S

OLO

button again to exit.

To select a different Channel for auditioning in Solo mode, remember that you must first select a Channel and then press the

S

OLO

button to enter Solo mode.

Mute a Channel

The method used for muting Channels is similar to that used for the Solo function— first select the Channel, then perform an action. There are some differences, however.

• You can mute as many Channels as necessary for your application.

• Channels that are muted can be saved as part of a Preset.

To mute a Channel, first select the desired Channel on the Personal Mixer. The red

37

Aviom A-16 Personal Monitor Mixing System

Channel LED should be lit. Next, press the

M

UTE

button to silence the Channel. The

Channel’s lower (yellow) LED will light to indicate that it is muted. Select any other

Channels that you want to mute and follow the same procedure to remove them from the current mix.

Unmute a Channel

Once a Channel is muted, you can follow this simple procedure to clear the mute:

• Select the muted Channel. (It should have the yellow LED in its button lit.)

• Press the

M

UTE

button.

• The yellow LED will go out.

• To clear mutes on other Channels, continue selecting Channels, followed by pressing the

M

UTE

button to clear the mutes.

Save the Preset with the mutes, if desired.

Note: Solo mode will temporarily override a mute. This guarantees that you will always hear the Channels you solo. When you exit Solo mode, the Channels are returned to their previous state.

Creating Groups

When you need control over more than just a stereo pair of Channels as described earlier using the Link function, you can use the Group function to control multiple

Channels. Up to three Groups can be created per user Preset. This means that every

Personal Mixer can have up to forty-eight different Groups saved by using all sixteen user Presets.

A Group can consist of any number of Channels, but Groups cannot overlap. That is, one Group cannot contain Channels that are part of another Group. Mono or linked stereo Channels can be part of a Group.

As you create a Group, the Channel volume and pan settings of each Channel added to a Group are retained. This helps to keep the overall blend of Channels that are part of a

Group even while you adjust the Group’s overall volume. The

V

OLUME

control changes the overall level of the Group.

Some examples of Groups in use:

• A Group allows background vocal parts from six singers to be adjusted together.

• All the drums in a live drum kit can be combined to a single stereo mix for easy adjustment for the guitar player, while the drummer retains individual control over each drum in his mix.

• Horns and woodwinds can be controlled together.

38 39

Aviom A-16 Personal Monitor Mixing System

38

• Multiple stereo keyboards can be combined into one source.

Creating and editing Groups is done in the Group Mode. To create your first Group:

• Start by selecting a Channel that you want to be included in the Group.

• Press the dedicated

G

ROUP

button on the left side of the Personal Mixer.

• Its red Group LED will begin to flash indicating that you can now edit the

Group.

• Double-click the Channel buttons to include a Channel in the Group.

• Channels that are added to the Group will flash their upper red LED to indicate that they are now part of the Group.

To Save your Group, simply press the

G

ROUP

button again. The Group LED goes out and you are returned to your current Preset and live mix.

In the current Preset, you will now see all Channel LEDs associated with a Group light whenever you press a Channel button that is included in your saved Group. The

Channels now behave as one.

Note: Remember to save the Preset if you want to be able to recall the Preset with the new Group settings later.

Creating Additional Groups

Three Groups can be created and saved in each Preset in a Personal Mixer. Each Group can be created and/or edited as needed while live audio is playing through the system.

The instructions in the previous section describe how to create and save the first Group in a mix. Creating additional Groups follows the same procedure. Use these steps to create a second and/or third Group.

• Select a Channel that is not currently part of an existing Group.

• Press the

G

ROUP

button to enter Group Mode. The Group LED will flash.

• Double-click any Channels that you want to add to the Group.

• To save the Group, press the

G

ROUP

button again. The flashing LED will go out.

Shortcut: While in the Group edit mode, you can start the process of creating a new

Group while editing an existing Group. To do this,

• Press a Channel button that is not already part of the current Group being edited. Its red LED will light solid.

• Double-click Channels to add them to a new Group.

• Create a third Group by following the same procedure.

• Exit the Group edit mode to save the Groups.

• Save the Preset.

39

Aviom A-16 Personal Monitor Mixing System

If you try to create more than three Groups, the interface will automatically select one of the existing Groups when you enter Group edit mode. You have the option at this point to edit an existing Group or clear Channels that are part of one of the other existing Groups.

Note: A Channel that is already part of one Group cannot be part of any other Group.

Making Changes to a Group

Once you have created a Group, you can edit it in a number of ways. You can add or delete Channels from the Group, and change individual Channel volume and pan settings.

To change a Group, start by selecting a Channel that is already part of a Group. All

Channel LEDs that are part of the Group will light. Press the

G

ROUP

button to enter the editing mode. The Group LED flashes.

Changing Channel Settings Within a Group

While editing a Group, you’ll notice that one LED in each Group is lit solid while the other LEDs are flashing. This solid LED indicates the Channel currently selected for editing. You can change its volume and panning without affecting other components of the Group. The changes you make to volume and pan affect only the selected Channel, allowing you to change the relative balance of the individual components of your

Group. Changes can be made in real time.

To select a different Channel in a Group for editing, press one of the flashing LEDs

(don’t double-click it). The new selection will light its LED solid, while the previously selected Channel will start to flash. Continue making changes as needed. Remember, volume and pan changes only affect the Channel whose LED is lit solid.

Removing Channels From a Group

To remove a Channel from a Group, simply double-click the Channel that you want to remove. The flashing LED will go out. To add other Channels to a Group, double-click them. When you have double-clicked to remove all Channels that were previously part of the Group you’re editing, the Group will no longer exist. You need at least two

Channels to have a valid group.

Exit the Group edit mode by pressing the

G

ROUP

button again. The LED in the Group button will go out. This saves your changes to the Group.

40 41

Aviom A-16 Personal Monitor Mixing System

40

Some points to note about Groups:

• Up to three Groups can be created per Preset.

• Groups are relative only to the Personal Mixer that they are created on.

• Groups you create on your Personal Mixer do not affect other Personal

Mixers being used in your system.

Remember that although you have edited and saved changes to your Group, you must still save the Preset if you want to recall the Preset with the new Group configuration intact.

Muting Groups

Groups can be muted if necessary while creating a mix or editing. The procedure is the same as for muting a single Channel. To mute a Group:

• First select one of the Channels that is part of the Group.

• The upper (red) LED in each Channel button that is part of a Group will be lit solid.

• To mute the Group, simply press the

M

UTE

button.

• The lower (yellow) LEDs in all Channel buttons contained in the Group will light, indicating that the Channels are now muted.

• Unmute the Group by pressing the

M

UTE

button again while the Group is still selected.

Note: The mute status of your Groups is saved as part of a Preset.

Aviom A-16 Personal Monitor Mixing System

Applications

This section describes how to set up and use the A-16 Personal Monitor Mixing

System in a variety of contexts.

Create a Mix With Console Direct Outputs

The direct output of a live or recording console allows you to take an exact copy of an input channel’s audio and patch it into the A-16T for processing. A typical console’s direct output point is right after the input, meaning that changes made on the console as far as effects, EQ, etc., do not affect the sound of the direct output.

The A-16T can accept up to sixteen direct outputs. You can use balanced or unbalanced cables to connect audio, depending on the configuration of your mixer.

The most likely scenario involves using a multi-cable snake to connect the main mixing board’s direct outs to the A-16T. It’s not a requirement, but rather a convenient method of keeping cable mess to a minimum.

Follow these steps to create a monitor mix with direct outputs:

• Connect a balanced or unbalanced cable from the direct output jack on the main mixer to the first input on the A-16T Transmitter rear panel.

• Repeat this procedure for the other console channels you want to add to the monitor mix.

• Select an appropriate Input Level setting on the A-16T front panel.

• Label the Personal Mixer with Channel names.

• Begin playing audio into the Personal Monitor Mixing System. Select a

Channel and set the volume and panning for each.

• Save the mix as a Preset.

At this point you can use the mix as is, or fine tune it by adding Groups, linking

Channels, etc.

Using Aux Sends to Create a Monitor Mix

An Aux Send (sometimes referred to as an Effects Send) can be used alone or in combination with other audio sources to create a monitor mix.

Using a fairly typical layout of a console with four Aux Sends, here is what you could do to send audio to the A-16T Transmitter to create a monitor mix. Again, remember that you can use any of the different types of audio signals available on your particular audio mixer to create a monitor mix (direct outputs, bus outputs, etc.).

42 43

Aviom A-16 Personal Monitor Mixing System

42

The example will use a band with a rhythm section (keyboards, bass, drums, and guitar) and a lead singer. Assume that all of the instrumentalists sing background vocals. The example assumes that you do not want to use any other type of output from the mixer. With four Aux Sends available on the mixing board, four independent sub-mixes can be sent to the A-16 Transmitter and then on to the A-16 Mixer units.

The first task is to separate the instrumental and vocal parts into four sub-mixes.

Imagine that we want a separate controllable level for the lead singer, background singers, drums, and the rest of the instruments. So, Aux Send 1 is assigned to Lead

Vocals, Aux Send 2 is assigned to Background Vocals, Aux Send 3 is assigned to the drums, Aux Send 4 is assigned to the instruments. All that’s left to do is connect four cables from the mixing board’s Aux Sends to the A-16 Transmitter.

Turning up the Aux Send 1 level on the mixing console sends the lead vocal to the

A-16 Transmitter. Since there is only one singer, there’s no sub-mixing or balance setting required.

The four musicians who sing background vocals will need to be blended at the main mixer. This will be done by sending audio from each of their microphones into Aux

Send 2. By changing the aux send level, you control the blend of the four singers, without affecting the mix created by the faders on the main mixer.

The same concept used to create a mix of all the background singer’s microphones is used for the drum kit and the instruments. The drums are sent to Aux Send 3, while the instruments are sent to Aux Send 4. At each musician’s A-16 Mixer, a custom mix can now be created. The singer can have more instruments, the drummer can have less background vocals and no drums in the mix, the instrumentalists can have their own background vocal level, etc.

Studio Cue System

In the studio, the flexibility of the Personal Monitor Mixing System will give performers more control of their headphone cue mix. At the same time it allows the engineer to spend less time fussing with the cue mix and more time making the tracks sound great.

Making a cue mix from a recording console is essentially the same as when using a live mixing board. If your board has direct outputs or unused auxiliary sends, you can use the same techniques as described for live audio monitor mixes.

Playback Monitoring

In the studio, performers also need to listen back to tracks they have just recorded.

If each performer is using a different mix while recording, playback of the track will

43

Aviom A-16 Personal Monitor Mixing System

be different in each set of headphones.

If you can dedicate two inputs on the A-16T Transmitter for playback, you can easily provide the performers with a high-quality playback of the track they have just recorded. Here’s how to set it up:

• Set aside the first fourteen Channels of the A-16T for audio tracks to be sent to the performers as a cue mix.

• The remaining two Channels are reserved for the stereo mix that the engineer creates in the studio.

• Connect cables from the console for monitoring the fourteen performer

Channels as described previously. Use direct outputs, aux sends, etc.

• Patch the stereo mix output that you want the performers to hear into the remaining two A-16T inputs.

The idea is that you will create two Presets on the Personal Mixers for the performers.

The first is their standard cue mix. It uses fourteen channels; the last two are muted.

They can change it as needed while they work. The other Preset is the exact opposite.

The performer’s fourteen cue channels are muted and the two channels containing the engineer’s playback mix are on.

For the example, let’s assume that Channels 1 through 14 are used for performer cue playback. Channels 15 and 16 will be used to play back the recorded track.

To complete the setup:

• On the A-16T front panel, set the Link switch on Channels 15 and 16 to the right, linked, position.

• On each Personal Mixer create a basic mix of the fourteen channels of audio.

• Mute Channels 15 and 16.

• Save the Preset (to location #1, for example).

• Create another Preset that has the first fourteen channels muted. (Shortcut:

Start by recalling the All Channels Zero Preset by holding

R

ECALL

and then pressing

M

UTE

.)

• Set a volume for the playback on Channels 15 and 16.

• Save the Preset (to location #16, for example).

When the musicians are cutting tracks, have them select Preset #1. Record tracks as usual, with each musician listening to their persoanal customized cue mix. When you want to listen back to a recorded take, have the performers switch to Preset #16. They now hear the engineer’s mix. All players hear the same mix, that the engineer can control as needed.

Of course the players can create additional cue mixes and save them to the remaining empty Preset locations as needed.

Using Console Inserts

When you use your console’s insert points to send audio signals to the A-16T Transmitter for processing, you have some options. The patching on the rear panel of the A-16T is designed so that you can still use the insert point on your console for its traditional use—adding an effect to a channel.

There are some special ways that the A-16T can be used to allow this flexible processing. The exact layout of your existing main mixer will influence how many of these techniques you can use.

Y Cable Insert

The A-16T can be used with a console’s insert send/return loop just as if it were an effects processor. If you have a console with a single TRS jack used for send and return of the effects loop, a “Y” cable is used to split the signal into two components. One is the Send, the other is the Return.

To use this type of insert with the A-16T, patch the Send cable into the In jack on the A-16T. Then use the Return cable plugged into the A-16T Thru jack to complete the loop back to the main mixer. The A-16T is now patched into the channel with no change to the audio signal. The console sees the A-16T as just another effects device.

Adding Effects

But what if you need to add an effect such as a compressor to the same channel? There are a couple of options. For both examples, start with the cables set up as just described for the simple insert example. You’ll need one more cable.

Monitor without the effect:

• Remove the cable from the Thru jack of the A-16T.

• Plug it into the output of the effect.

• Connect a cable from the A-16T Thru jack to the input of the effect. The send/return loop is complete and now includes the effect. You do not hear the effect in the monitors.

Monitor with the effect:

• Remove the cable from the In jack of the A-16T.

• Plug it into the input of the effect.

• Connect a cable from the output of the effect to the A-16T In jack.

• Leave the cable already connected to the A-16T Thru jack as it is. It completes the loop.

Using a Balanced TRS Cable

A single balanced cable can be used to complete an insert send/return loop when used with the A-16T Transmitter. In this case, the send and return loop will be completed

45

Aviom A-16 Personal Monitor Mixing System

when you patch a TRS cable into the A-16T Thru jack. This is an important point to

remember, and is not a typo. The upper jack on the A-16T will complete the loop when used this way.

If the same cable were to be plugged into the bottom In jack, only the Send portion of the loop would be connected. Although not an undesirable audio connection, this would not complete the signal loop.

Adding Effects When Using a Single Balanced Cable

The setup described above completes an effect send/return loop with a single cable. To add an insert effect processor using this setup, the In jack on the A-16T Transmitter can be used. All that is needed is a standard insert-style Y cable (TRS on one end, with a split to two mono cables on the other). The effect Send must be on the tip of the cable for this to work. If your mixing board uses the ring for the Send, you can wire a special cable to be used for this purpose.

To add an effect, follow these steps:

• Connect the balanced TRS cable from the main mixer’s insert point to the

Thru jack on the A-16T. This inserts the A-16T into the signal path and completes the loop.

• To add the effect (such as a compressor) connect an insert Y cable’s TRS plug to the A-16T In jack

• Plug the Send cable on the other end of the Y cable to the input of the effect processor.

• Plug the Return cable on the Y cable into the effect’s output. This completes the loop.

You can wire much of the same functionality described above into a patch bay for more permanent installations. Remember to use the same type of cables and patch bays—balanced cables with balanced patch bays, unbalanced cables with unbalanced patch bays.

Using a Patch Bay

The A-16T Transmitter’s input and through connections can be wired into a patch bay for flexible and repeatable connections day after day. This concept can work for both studio applications and live performance.

You can use either balanced patch bays or unbalanced. One point worth mentioning— use matched systems. That is, if you have a balanced patch bay, use balanced audio cables for interconnections. If your patch bay is unbalanced, use unbalanced cables.

A-16T In and Thru Patching

Not to be confused with patching the A-16T into a mixer’s insert send/return loop, this

46 47

Aviom A-16 Personal Monitor Mixing System

46 is a simple wiring idea for having access to the A-16T rear-panel In and Thru connections. It allows permanent installations to have access to the flexible patching options of the A-16T as needed.

In the studio this allows you to patch direct outputs to the A-16T one day, and then use a combination of aux sends, direct outputs and console bus outputs another day without reaching behind an equipment rack.

This setup is designed for a patch bay that is not normalled. A normalled patch bay is one that automatically sends the signal from one jack of the patch bay (typically the top row) to another jack (typically the lower jack).

To connect a patch bay using this configuration:

• Use balanced or unbalanced cables (depending on your patch bay) to connect the A-16T row of Input jacks to one row of the patch bay.

• Patch another set of cables from the A-16T Thru jacks to another row of the patch bay.

• Patch an audio signal into the Input row of the patch bay.

• The signal is processed by the Transmitter. It will appear in the Personal

Mixers.

• To send the signal elsewhere in the studio, patch a cable into the Thru row on the patch bay.

• Repeat these steps to add additional audio signals to the mix.

Adding Effects to a Monitor Mix

Sometimes you may want to have reverb, delays, etc. sent into the monitor system.

This works for studio cue systems as well as for live applications. There are two ways of accomplishing this:

• Patch the effects returns from the mixer into the A-16T via insert points if available.

• Connect the effects device outputs to the A-16T first and then use the Thru jack on the A-16T to complete the signal chain.

In either case the performers can now decide how much reverb is required in their personal mix. And, they can save up to sixteen mixes with various amounts of effects in each.

Adding Live Ambience to a Monitor Mix

For performers using in-ear monitors in a live-performance situation, it may be desirable to add some room tone into the monitor system to help add a sense of space. This technique can be used with most live consoles. All you need is a way to send the signal from a pair of stage or room mics into the A-16T Transmitter.

47

Aviom A-16 Personal Monitor Mixing System

If you are using direct outputs from channels to send instrument and mic signals into the A-16T, you need to dedicate two channels to the mics that are picking up the ambient sound. It is not necessary that the live mics be sent into the front of house mix.

Silent Jam Session

There is no requirement that a mixer be used with the Personal Monitor Mixing System. In fact it makes a great late-night jam session environment for keyboard players, guitarists, and electronic drummers, etc.

To set up a silent headphone system for jamming:

• Connect the outputs from stereo keyboards to inputs on the A-16T.

• If the keyboard player uses a sub-mixer, you can optionally connect the stereo output of the keyboard mixer to two inputs on the Transmitter.

• Patch the output of a guitar amp simulator into a pair of inputs.

• Connect an electronic drum kit’s outputs into the A-16T.

• Set the Link switches on the A-16T for any stereo Channel pairs.

Other Uses for the Personal Mixer Outputs

The stereo audio outputs on the A-16 Personal Mixer can be used with stereo headphones, in-ear monitors, or powered speakers. But, since the outputs are at line level, they are capable of sending the current monitor mix to any audio device capable of using a line level audio signal.

Record a Mix

The output of your Personal Mixer can be used for recording. To connect the stereo

TRS line output to some devices you may need to use an adapter to split the signal into two separate mono outputs—one for the left side, the other for the right. To record the output of a Personal Mixer:

• Create a mix. Use panning, mutes, Groups etc. as required.

• Save the Preset to a memory location.

• Connect the line outputs of the Personal Mixer to the inputs of the recorder. (You may need a special cable to split the stereo signal into dual mono signals.)

• Play back the mix you created.

• Set an appropriate audio level for recording on the device. Use the Master volume control to set a level that does not distort the inputs of the recorder.

Using this technique you can quickly create a variety of recorded tracks for rehearsals, etc. by recording the different Preset mixes saved on your Personal Mixer.

48

Troubleshooting

Before contacting Customer Service, check the following list of common problems and solutions for help.

Problem: No audio from Personal Mixer outputs

Possible Solutions:

• No input audio from the main mixing console. Check the levels of the main mixing board that the system is connected to.

• Check the cables and connections between the main mixer and the A-16 system. The Signal LEDs on the front of the A-16T can be used to confirm that audio is being received.

• Bad cables; try a replacement.

• All Channels on the Personal Mixer are at zero.

• Master volume level on the Personal Mixer is at zero.

• A-Net cables are not connected properly.

Problem: Can’t change Presets

Possible Solutions:

• Make sure that the

R

ECALL

button has been pressed. Its LED will flash, indicating that you should press a numbered button to recall a Preset.

Problem: Can’t hear a Channel that is part of a Group

Possible Solutions:

• The Group might be muted. Check the lower (yellow) LED in the Channel buttons. A lit yellow LED indicates the Channel is muted. To unmute it, press the

M

UTE

button while the Group is selected. The yellow LED must be unlit in order to hear the audio on that channel.

• The Channel volume is all the way down. In Group edit mode, select the

Channel and check the level for that Channel by looking at the LEDs in the Volume indicator. If no LEDs are lit, then the Channel is turned all the way down. Raise the volume by turning the Channel

V

OLUME

knob; re-save the Group and Preset if necessary.

Problem: The A-Net LED is on, but there is no sound

Possible Solutions:

• The A-Net Active LED indicates that the input to the receiving device is properly connected to another A-Net device. It does not indicate that all devices in a system are properly connected, however. If you have two

Personal Mixers connected together, the second Personal Mixer’s A-Net

LED will light because the first Personal Mixer is correctly connected to it. Check that each device in the chain has a Category 5 cable plugged into it.

• Check that the A-Net cables are connected in the correct order. The Cat 5

49

Aviom A-16 Personal Monitor Mixing System

cable connected to the first Personal Mixer should be connected to the A-

Net In jack. The next device is connected from the Out on the first device to the In on the next.

Problem: A Preset was saved with a stereo link active but when the Preset is recalled the channels are mono. (Or, a Preset was saved with mono channels, but on recall the Channels are linked.)

Possible Solutions:

• The status of the stereo link is set by the front panel Link switches on the A-16T Transmitter. If a Preset is recalled and the position of the

Link switch is different from when the Preset was saved, the Preset will be adjusted to agree with the current hardware settings on the A-16T

Transmitter front panel. If this happens, simply change the position of the

Link switch on the A-16T. Your current mix will be updated immediately.

Problem: A Channel was assigned to one Group and now it is suddenly part of a different Group.

Possible Solutions:

• When you link a stereo Channel pair with the Link switch on the A-16T after a Group has been created, it is possible that channel characteristics could change. This includes the volume, pan, mute status, and Group assignment. The rule to remember is that the even-numbered channel (the right side of the pair) will inherit the characteristics of the odd-numbered channel (left side of the pair).

Problem: When editing a Group that contains a large number of Channels, it seems like all of the LEDs are pulsing.

Possible Solutions

• This is a normal effect of the current-limiting circuit and is not an indication of a problem.

Problem: I don’t think my Preset was saved.

Possible Solutions:

• When saving a Preset, make sure that the

R

ECALL

and G

ROUP

buttons are both held down before pressing a memory location button. The Preset is saved when you release your finger from the memory location button.

When a Preset has been saved correctly, you will see all sixteen Channel

LEDs flash momentarily to confirm the save operation.

Problem: In Group mode, I can’t select a new Channel.

Possible Solutions:

• If you already have three Groups defined and attempt to select a new

Channel that is not part of an existing Group, the button press is ignored.

This happens you are trying to create a new which would exceed the limit of three Groups per Preset. Edit or delete an existing Group to continue.
