1. INTRODUCTION.

1.1. General overview.

AEQ FORUM

and AEQ GRAND FORUM are digital audio mixers for Broadcast applications, specifically designed for ON AIR applications and highly adaptable to different operational situations. They incorporate all the basic features needed in such environments: automatic monitors muting, cough muting, fader-start, signalling control, control signals for external equipment automation, management of external communications, intercoms, etc.

The modular design and reduced size makes those mixers perfectly adaptable to many different scenarios: self-control, control-studio, audio control in television, sound production, mixed configurations, integration in large systems, etc.

One of the main qualities of both them is the extensive internal routing capacity which provides: up to 64 inputs/outputs for analogue, digital or microphone audio signals, and another 64 input/output multichannel audio over a MADI link (in order to activate this function you must purchase a user license).

NOTE: The exterior of the equipment and some screens or displays may vary depending on version.

The power of control and simplicity are combined in AEQ FORUM to cover both basic and advanced operating needs, starting with a 4 faders control surface that can easily be expanded to 8 or 12 faders; in the case of AEQ GRAND FORUM, it can be expanded up to 16 or 20 faders.

All basic functions of activation, level adjustment and routing have their specific controls on each channel of the FORUM surface, while less common adjustments are included in a set of contextual controls common to all channels and accessible with just one or two keystrokes: simplicity and clarity of use for dynamic control without handling error.

The flexibility offered through the configuration of the system enables the free assignment of any audio input of the system to any control channel, and changing the distribution of signals from the surface itself or the associated configuration software.

The digital mixer includes memory banks that store the settings for each signal: control surface signal distribution, routing to the output buses, management of parameters and activation of the different available audio processes. This allows the console to adapt easily to different programs with different technical requirements.

Its two Ethernet ports enable the local or remote interconnectivity, facilitating set-up and maintenance, monitoring and control.

Forum has also been designed to ensure interoperability with communications equipment and future developments by AEQ or other manufacturers.

AEQ FORUM


2. PHYSICAL DESCRIPTION OF THE UNIT.

AEQ FORUM is a self-contained, compact digital mixing console, which means that its two functional blocks are housed in the same physical chassis. On one hand the control surface, where the controls and status indicators are located and on the other, the "audio engine" which contains all electronics for audio inputs and outputs as well as routing blocks, summing and processing.

Both functional blocks will be separately described below.

2.1. Description of the control surface.

Control surface is the operators work area of the AEQ FORUM. All the operational organization, management and implementation of the audio program is accomplished from this area. The control surface incorporates all the keys, screens, faders, encoders and VU meters required to easily operate the equipment.

There are two different areas on the AEQ FORUM control surface: the area that corresponds to the audio channels controlled through faders (each module includes 4 faders) and the

"CONTROL AND MONITORING MODULE" which is normally located to the right.

2.1.1. Channels.

The AEQ FORUM control surface is built on independent modules of 4 faders called "FRCH".

The control surface capacity can be expanded from a basic configuration of 4 channel faders to

8 and up to 12 channel faders. For AEQ GRAND FORUM, it can be expanded up to 16 or 20

faders.

The assignment of signals to channel faders on the AEQ FORUM is completely user definable.

It is possible to assign any signal to any channel fader at any time. This allows for the redistribution channels to adapt to different programs or operators.

In addition, different channel assignment of signals can be stored in memory to be used by different users or applications.

In addition to the signals on channel faders present on the control surface that can be mixed, processed and sent to any output channel, the AEQ FORUM is capable of routing and adjusting the levels for other hidden signals up to 128x128 audio signals.

6

AEQ FORUM


Located in the upper part of the channel are 4 routing keys (“PROGRAM“,“AUDITION“,“AUX1“ and “AUX 2“) and a “SELECT” button to assign the channel to advanced settings common control (gain, dynamics, EQ and balance).

Beneath this section, an OLED display shows channel name and status for balance or pan.

Immediately under the display is located the Pre-listen button “CUE”, 4 status indicators LEDs that alerts with regards to the activation of equalization (“EQ“), dynamics (“DYN“), balance

(“BAL“) and gain (“GAIN“). Also in this section, a luminous label indicating that the channel is activated and is sending signal to the output buses (“ON AIR”).

By pressing the “SELECT” button the advanced configuration functions are enabled. These configurations are accomplished within the integrated multifunction display in the control and monitoring section at the far right of the control surface. Its operation is based on rotary encoder and graphical menus and short-cut function keys, depending on the information shown on screen.

Among the general functions are the instant activation and adjustment of audio effects (EQ, filters, limiters, etc.), configurations and memories management, disconnection of applied effects, phase change, inserting of a test signal, as well as clock, timer and stopwatch for timing control, etc. For more information see chapter “3. DESCRIPTION OF THE INTERNAL MENU” of this manual.

The Channel module is completed with plastic conductive sliding faders and the Channel ON and OFF buttons.

AEQ FORUM


2.1.1.1. Routing keys.

There are four keys on the top of the channel that routes the channel signal to the corresponding output bus. Activation is indicated through the integrated LEDs in each of these keys, and indicates the creation of a cross point between the input signal on the channel and the output channel corresponding to the key.

From left to right and top to bottom, the four keys of direct routing are “PROGRAM“ (sending to master 1), “AUDITION“ (sending to master 2), “AUX1“ (sending to auxiliar 1) y “AUX2“ (sending to auxiliar 2). The allocation of physical outputs associated with these signals and the physical circuits of the inputs/outputs modules on the back of AEQ FORUM is accomplished from the configuration software. For more information, please refer to chapter “4. CONFIGURATION

SOFTWARE

” of this manual.

2.1.1.2. SELECT.

The control surface of AEQ FORUM offers the usual controls for a mixing console on each channel, but AEQ FORUM also offers a wide range of possibilities for routing and processing, beyond the physical options included in each channel. These possibilities have been distributed in a logical manner within internal menus accessible from the main screen of the Control and

Monitoring section.

The operation is intuitive, always beginning with pressing the “SELECT” button on the channel that you want to process and moving to the main screen of the Control and Monitoring section of the console to accomplish the activations or adjustments. For further details please refer to chapter 3.4.3.1 of this manual.

2.1.1.3. Channel display.

Each of the 12, 8 or 4 channels (depending on the AEQ FORUM configuration ordered) integrates a two-colour OLED display (yellow/black) showing:

• Name of the associated audio signal (maximum 6 characters, editable via the configuration software). For more information see chapter “4. CONFIGURATION SOFTWARE” of this manual.

• Status of balance between left (L) and right signal (R) in stereo signals (or panoramic for monophonic signals).

AEQ FORUM

2.1.1.4. CUE.

This button allows you to activate a pre-fader listening to the audio channel for monitoring and control. When activated the integrated LED is lit. It is possible to send the audio signals of several channels to the CUE bus, acting as a summing bus.

There is the option of setting one of the programmable keys on the Control and Monitoring section (C&M) as a general “CUE RESET” that disconnects all active signals from the CUE bus.

CUE signal associated controls

The CUE speaker is built-in in the upper right of the control surface, beneath the ventilation grille, and the volume control is through an encoder in the Control and Monitoring section of the control surface.

2.1.1.5. Indicators of active processes.

Under the “CUE” button there are four blue LEDs with corresponding labels, from left to right and top to bottom, “EQ” (equalizer), “BAL” (balance), “DYN” (dynamic processor) and “GAIN”.

The lit status indicates the activation of any of the four processes previously mentioned in a certain fader channel.

These four processes (EQ, dynamics, balance and gain) are controlled from the internal menu associated with the “SELECT” button on the main screen of the Control and Monitoring section.

AEQ FORUM


2.1.1.6. ON AIR LED.

Under the lights of active processes is located the “ON AIR” warning light. This light is ON when the audio signal present at the input of the channel is sent to any of the outputs previously described (see section “3.4.3.1.3.2 ROUTE menu” of this manual).

For this, two conditions must be met simultaneously:

• Channel fader is located in any position except at minimum of travel of the fader.

• Channel ON key is activated.

2.1.1.7. Fader.

100mm conductive plastic fader. The fader travel is printed with 11 bands, the maximum output level +22dB corresponding to the last, and the third band from above to +0dB or nominal operating level. Both of these marks are differentiated in size from the rest.

The response mode of the fader is logarithmic, producing great attenuation of the level at the bottom of the fader travel and less adjustment at the top.

The bottom position of the fader travel, triggers gain -∞dB or absence of signal, which is also reflected in the channel “ON AIR” indicador (it turns off).

10

AEQ FORUM


2.1.1.8. Channel activation keys.

The channel activation keys, “CHANNEL ON/OFF”, enable or disable the sending of the audio signal present at the channel input to the outputs previously defined. If the sliding fader is located in any position of the fader travel other than the minimum, the channel on or off activation will be reflected through the “ON AIR” indicator previously described.

The upper key is associated to ON function and has a red light built in and the lower one is associated to OFF function and has a yellow light. The operation is exclusive, both keys can not be turned on simultaneously.

These keys can be activated remotely by GPI. To configure remote activation, see chapter

4.2.3.1 of this manual.

2.1.2. Control and monitoring section.

The control and monitoring section (C&M) of the control surface is usually located to the right.

This section enables the overall management of the signals on the system, including routing and control processes, as well as monitoring of the signals used in developing the final program, by means of the VU-Meters, and CUE control.

This control and monitoring section is divided into four main areas:

• Control VU meters: allows you to monitor visually the level of the audio signals from the master output and the CUE bus (or the control monitoring bus, when there are no channels sent to CUE).

• Programmable keys: dedicated buttons with special functions defined through the configuration software.

• Main screen: it displays the internal menus. This section also incorporates contextual keys and encoders.

• Studio, Control and Talk-back monitoring: where you can manage the audio signals sent to the headphones and speakers, for the control room and the studio room, as well as the talk-back functions for the intercom for both areas.

11

AEQ FORUM


IMPORTANT NOTE:

There is an edition of the board that form the control and monitoring section where the control VU meters and the programmable keys are placed in vertical position, instead of horizontal. The operation is not different from the described in the following sections; the only detail to take into account is that in that case the VU meter that shows the Program output is the one placed at the left and the one that shows the CUE bus (or the control monitoring one) is the one placed at the right.

2.1.2.1. Control VU meters.

There are two 40 segment LED stereo VU meters. The upper one shows the Program output and the lower one the CUE bus (or the control monitoring bus, when there are no channels sent to CUE).

From left to right, the first 25 LEDs are green, followed by an area of 5 yellow LEDs to finish with an area of 10 red LEDs. 0dB point or nominal value corresponds to the the yellow LED adjacent to the first red LED.

Both VU meters are set to function as IEC268-10: 5ms/-2dB (vu-meter only) and the peak-meter

IEC268-17: 300 ms (vu-meter & Flying PPM) superimposed.

2.1.2.2. Programmable keys.

The Control and Monitoring area of the AEQ FORUM includes 15 programmable keys in three rows of 5 columns.

12

AEQ FORUM


These programmable keys can be configured through software to perform specific functions such as salvos, GPI, GPO, external codecs control. For more information see section 4.2.1.2 of this manual.

The operation of the programmable keys allows two possibilities:

• NORMAL: the pressing of the key triggers the the execution of the programmed action.

Pressing it again will produce the end of the previously launched action, or in the case of SALVOS, even the opposite action or disconnection of the SALVO.

• PTT (PUSH-TO-TALK): the pressing of the key will trigger the execution of the programmed action but only remains active as long as you keep the button pressed.

All keys can be easily labelled, removing the translucent plastic cover and inserting a text label.

AEQ supplies with the equipment a template that allows you to create these labels on clear acetate or plain paper.

2.1.2.3. Main screen.

The main screen is a two coloured OLED (yellow/black) 128x64 pixel resolution display, that shows the entire internal advanced menu of the AEQ FORUM. For more information see section

“3. DESCRIPTION OF THE INTERNAL MENU” of this manual.

To simplify operations in the internal menu shown on this screen there are four short-cut keys and three associated rotary encoders. Depending on the information shown on the last line of the menu screen visible on the main display, these short-cut keys will have a function or another.

At most, the last line will have four menu options visible from left to right, and they are directly associated with short-cut keys from left to right.

AEQ FORUM


13

The three rotary encoders are related to the remaining lines of the menu. Each screen is described in chapter 3 of this manual but the thumb-rule for the association of the rotary encoder to the visible functions is: option visible to the left or in the upper part of the menu is controlled from the encoder located to the left. In many cases the encoders are represented and labelled on the screen for easy operation.

2.1.2.4. Control room monitoring section.

Located in the lower right corner of the AEQ FORUM control surface are a two-coloured display, three rotary encoders and four keys.

• In the two-coloured OLED display are shown the output levels for the control monitoring signals and the selected sources in each case, for control headset, control speakers and CUE.

• The three rotary encoders, from left to right, are: o

“MONITOR“: it controls the audio level for the physical output for the control room monitors. To decrease the level turn the encoder to the left. To increase the level turn the encoder to the right. o

“HP/SOURCE“: it controls the audio level for the physical output for the control headphones. To decrease the level turn the encoder to the left. To increase the level turn the encoder to the right. This encoder can also be used to select the signal to monitor associated with the key “SEL”: press to access a list of signals, and turn the encoder to move up or down in the list of signals; pushing the encoder a second time confirms the selection of the highlighted signal. o

“CUE“: it controls the audio level of the CUE speaker of the AEQ FORUM. To decrease the level turn the encoder to the left. To increase the level turn the encoder to the right.

• The four keys under the display allows to select the signal to monitor on control speakers and headset, from left to right: o

“PROG“: allows you to monitor the audio signal Program. o

“AUD“: allows you to monitor the audio signal Audition. o

“SEL“: allows you to monitor any signal of the console previously selected by means of “HP/SOURCE“ encoder. o

“CUE“: allows you to monitor the audio signal present on the CUE bus.

These four keys can have two working modes that are selected from the Configuration

Software (see section 4.2.4 of this manual):

14

AEQ FORUM


o

“Mixer”: each key pressed adds the signal to be monitored to the summing bus. o

“Exclusive”: each key pressed connects the signal to the summing bus and disconnects any signal previously selected.

In case there are no channels sent to CUE, the signal or signals selected in this section will be shown in the lower control VU meter (see section 2.1.2.1 of this manual).

2.1.2.5. Studio room monitoring section.

Located in the lower left corner of the AEQ FORUM control surface are a two-coloured display, three rotary encoders and four keys.

• In the two-coloured OLED display are shown the output levels for the studio monitoring signals and the selected sources in each case, for studio headset, studio speakers and

CUE.

• The three rotary encoders, from left to right, are: o

“LEVEL” (Talkback Level): it controls the gain of the TALKBACK microphone.

To decrease the level turn the encoder to the left. To increase the level turn the encoder to the right. o

“MONITOR“: it controls the audio level for the physical output for the studio room monitors. To decrease the level turn the encoder to the left. To increase the level, turn the encoder to the right. o

“HP/SOURCE“: it controls the audio level for the physical output for the studio headphones. To decrease the level turn the encoder to the left. To increase the level, turn the encoder to the right. This encoder can also be used to select the signal to monitor associated with the key “SEL”: press to access a list of signals, and turn the encoder to move up or down in the list of signals; pushing the encoder a second time confirms the selection of the highlighted signal.

• The four keys under the display allows to select the signal to monitor on studio speakers and headset, from left to right: o

“PROG“: allows you to monitor the audio signal Program. o

“AUD“: allows you to monitor the audio signal Audition. o

“SEL“: allows you to monitor any signal of the console previously selected by means of “HP/SOURCE“ encoder. o

“CUE“: allows you to monitor the audio signal present on the CUE bus.

15

AEQ FORUM


These four keys can have two working modes that are selected from the Configuration

Software (see section 4.2.4 of this manual): o

“Mixer”: each key pressed adds the signal to be monitored to the summing bus. o

”Exclusive”: each key pressed connects the signal to the summing bus and disconnects any signal previously selected.

2.1.2.6. Talkback.

Talk-back section allows the console operator to communicate directly with the studio and remote guests (lines).

The default intercom channels for the AEQ FORUM are between the control room and the studio, independent between monitors and headphones. You can set additional channels of intercom to facilitate communications. For example, talk-back can be established between studio or control to the different audio returns to hybrids or audio-codecs. The talk-back microphone can also be used as an auto-control microphone if so defined.

The talk-back section of the control surface consists of 4 key buttons immediately beneath the

Studio and Control sections and the encoder “LEVEL” (Talkback Level) of the Studio monitoring section.

From left to right are:

• “MON“: talk-back to studio monitors.

• “HP“: talk-back to studio headphones. The default configuration of the AEQ FORUM does not differentiate between primary and secondary headphones. It is possible to establish a secondary group of headphone creating a salvo to be triggered from the programmable keys.

• “TEL 1“: talk-back to the telephone hybrid line 1 (AEQ FORUM allows a maximum of 2 single line digital telephone hybrid modules FR33, but has 8 MPX internal buses hidden that can be used with dedicated lines, external audio codecs or telephone hybrids. The talk-back to dedicated lines, external audio-codecs or telephone hybrids can be established through the use of the programmable keys).

• “TEL 2“: talk-back to the telephone hybrid line 2.

2.1.3. Ventilation grille.

The base of the equipment and the top of the control surface have micro-perforations to allow the passing of a stream of air naturally created by convection due to the heat dissipated by the equipment electronics. The distance form the equipment base to the table top has to be respected by at least the height of the equipment rubber feet and it is paramount not to obstruct the ventilation grille on the top of the control surface.

16

AEQ FORUM


The AEQ FORUM design does not include a fan or mechanical heat sink thus ensuring silent operation, perfect for self-control facilities or applications that require absolute silence.

The right side of the vent area integrates the CUE speaker.

2.1.4. Wrist-rest and side trims.

The AEQ FORUM has a frame around the sides and bottom of the control surface, forming part of the chassis that houses all the electronics. This framework is transformed into a wrist-rest at the bottom.

The standard AEQ FORUM is delivered with wooden side trims and a wrist-rest for desktop installation of the mixer. As an option, the AEQ FORUM can be provided without the side trims and with L-shaped metal profiles to allow the countersunk installation of the mixing console.

AEQ FORUM


17

2.2. Description of the rear panel and connections.

The ease of installation and set-up has been a priority in the design of AEQ FORUM. The equipment is self-contained and can be installed either desktop or countersunk.

To connect cough cut, remote control of external devices, ON AIR lights, etc... AEQ FORUM has 8 general purpose inputs (GPI), 8 general purpose outputs (GPO) and another 4 relay outputs. The AEQ FORUM has a set of predefined control and studio monitors and headphones including auto-control and orders microphone. Remote configuration and control is via two

Ethernet connections.

AEQ FORUM has an optional bi-directional MADI interface (available by means of user license) that can carry up to 64 digital inputs and outputs as well as 14 slots for analogue or digital I/O and digital telephone hybrid modules.

For ease of wiring and avoid errors in the installation process, audio and data cables and DB connectors required to connect the console can be optionally supplied. In any event, it is necessary to use shielded and balanced audio cables and that the connection to the DB connectors are made by technically qualified personnel and properly verified before connecting the equipment. Further, optional power supplies and wiring for control and studio signalling and

GPIO can be supplied.

2.2.2.7. Optional MADI communications module.

On the rear panel of AEQ FORUM you can find the physical connector for the AES10 - MADI interface built into the console. The connector is an SFP chassis (Small Form-Factor Pluggable

- SFP) where you allocate the optional fiber-optic transceiver.

MADI protocol, which stands for multichannel audio digital interface is a professional standard of data transmission for digital audio signals over 56 channels on a single cable. MADI protocol is documented in the standard AES10-1991 and ANSI s4.43-1991.

AES10 MADI multichannel interface is an extension of AES3 protocol for interconnection of multi-channel. MADI protocol, as defined in the AES10 standard allows connection of up to 64 audio channels (linearly quantified data) with a resolution of 24 bits per sample and a sampling rate frequency of 48 kHz/s. Transmission is accomplished in a serial mode and if transmission is done on a single 75 ohm coaxial cable with BNC connectors the distance reached is greater than 50 m. If transmission is accomplished on a multi-mode fiber-optic interface the distance is up to 2 km.

The audio samples may have a maximum of 32 bit quantization. Additionally, by using this protocol, the bits of validity user status and parity of AES3 are maintained. The MADI protocol allows you to connect 64 audio channels with a single pair of wires. The data bit rate is 100

MBits/s corresponds to a synchronous connection.

MADI Interface Specifications:

• Optical fiber connector, FDDI PMD type.

• Nominal range: 2.000 meters

• Fiber Type: 62.5 / 125 µm MULTIMODE MULTIMODO

• Transmission: LED, 1300 nm

NOTE 1:

in order to activate this function you must purchase a user license.

3. DESCRIPTION OF THE INTERNAL MENU.

The AEQ FORUM internal menu is displayed on the main screen of the Control and Monitoring section of the control surface.

Most of them allow you to modify the values shown (although some screens of the internal menu are merely informative), changing routing, gains or applying processes to the audio signals. For this purpose, the three rotary encoders and the four contextual keys associated to this screen will be used.

Depending on the information shown on the last line of the menu display, the four contextual keys immediately beneath the display will have different functions. This last line of the menu will have a maximum of four visibles options.

The three rotary encoders are associated with the options shown in the menu (each specific screen will be explained in detail later in this manual). The specific association of the encoders is following the next thumb rule: the menu option that is shown farthest to the left or in the highest position is controlled from the encoder located farthest to the left.

The default screen in AEQ FORUM shown in the main Control and Monitoring section display includes the AEQ logo, the product name, the active user level and current date and time.

The four options visible on the last line of the display are associated with the four contextual keys below, from left to right:

• “CLOCK”: allows you to access to the system date and time configuration menu, as well as to the chronometer and countdown availalble functions.

• “LOGOU”/“LOGIN”: allows you to access to the users registration menu (“LOGIN”) or leave the current active user (“LOGOU”).

• “MEMORY”: allows you to access to the system snapshot memory bank. There are 7 memory positions available in order to store different configurations.

• “MENU”: allows you to access to the advanced menu for audio inputs/outputs, routing and processing configuration.

In the upper right part of the display the level of the active user is shown (it changes between

“BASIC”, “ADVAN” and “ADMIN”). For more information, please refer to section “3.2.

LOGIN/LOGOUT menu

” of this manual.

3.1.

“CLOCK“ menu.

This menu enables you to set the date and time displayed in the system (but not the option of synchonization with a external master clock, which is only configurable from the configuration software: see section 4.2.5 in this manual), as welll as activate and control the Chronometer and Countdown functions.

The initial screen shows the current system time (HH/MM/SS) and, up on the right, the date

(DD/MM/YY).

33

AEQ FORUM



• “BACK”: returns to the previous menu screen.

• “SET”: enables you to access to the date and time configuration menu. When you access to this menu, the time configuration is available (a flashing arrow is displayed next to the current time) by means of using the 3 rotatory encoders (turning the first one allows you to change the hour, the second one the minutes and the third one the seconds).

When you press the “DATE” contextual key, you access to the date configuration menu (the flashing arrow changes its position and the “DATE” changes to “TIME”): by pressing the first encoder you can change between day of the week and day of the month and by turning it allows you to change the selected option; you can configure the month by turning the second encoder and the year by turning the third one.

Once date and time are configured, you can press the “SET” key in order to save the changes and return to the previous screen or the “BACK” key in order to return to that screen without changes saving.

• “CDOWN”: lets you configure and activate the AEQ FORUM Countdown option through the associated rotary encoders. The format on screen is HOURS:MINUTES:SECONDS.

You can configure the hours by turning the first encoder, the minutes by turning the second one and the seconds by turning the third one. The “START” contextual key launches the countdown, the “STOP” key (the same key that changes its function) brings it to a stop, and the “RESET” key re-establishes the initially configured value

(even when the countdown is launched). The “BACK” key allows you to return to the previous screen (it also stops the countdown and re-establishes the initial value).

AEQ FORUM


34

• “CHRONO”: enables you to configure and activate the chronometer option. The format on screen is HOURS:MINUTES:SECONDS.

The “START” contextual key initiates the chronometer, the “STOP” key (the same key that changes its function) stops it, and the “RESET” key re-establishes the initial zero value (even when the chronometer is launched). The “BACK” key allows you to return to the previous screen (it also stops the chronometer and re-establishes the initial zero value).

3.2.

“LOGIN/LOGOUT“ menu.

This menu allows AEQ FORUM users/operators to register in the system, so that the equipment recognizes their user level by the associated password, and assigns them an access level for subsequent operation in the different console submenus.

AEQ FORUM enables up to 4 different user levels, each with its associated profiles and passwords:

• LEVEL 0: users with no associated password. You can access to this level by pressing the “LOGOU” contextual key in the initial menu (that key changes to “LOGIN”). The operation is limited to raising and lowering faders, activate/deactivate the 4 routing keys and the CUE key of each channel, activate/deactivate channels (“CHANNEL ON/OFF”) and use the programmable keys and monitoring section. The “SELECT” key of each channel is not active and neither the options visible on the last line of the main menu

(“CLOCK”, “MEMORY” and “MENU”); the “LOGIN” option is available in order to change user.

• LEVEL 1: these users are defined in the configuration software with “Basic” access level (see section 4.1.2 in this manual). In the initial screen, up on the right, the indication “BASIC” is shown to identify this level.

The “LOGIN”/“LOGOU” contextual key has two possible uses: LOGIN to register yourself

(depending on the password used you will access to a certaind level) and LOGOUT to deregister (this way you gain access to level 0). When you register through the option “LOGIN”, the “PASSWORD” screen appears: six spaces are displayed on screen associated with the six digits (as maximum) of the password. The password must be configured previously from the configuration software (see section “4. CONFIGURATION SOFTWARE” of this manual). The password supplied by default for “ADMIN” user (LEVEL 3) is 1234.

The procedure for entering the password requires the use of the contextual keys beneath the display and any of the three associated encoders.

By turning any of the 3 encoders you can select the desired digit; by pressing any of the 3 encoders you can confirm your selection as part of the password and change to the following position (when you press an encoder after selecting the sixth digit, it’s equivalent to press the

“OK” key).

The four contextual keys are associated with the four options displayed in the bottom line of the display:

• “BACK”: pressing this key allows you to return to the previous menu screen.

• “PREV”: enables you to move to the left through the six positions that make up the password.

• “NEXT”: enables you to move to the right through the six positions that make up the password.

• “OK”: allows you to confirm that all the digits of the password have been entered and, if password is correct, change to the associated user (the main display shows then the initial AEQ FORUM screen with the user level up on the right and the second contextual key identified as “LOGOU”). When you enter an incorrect combination of digits, a

“WRONG PASSWORD” message is displayed (the “BACK” key allows you to return to the previous screen in order to insert the password once again).

“MEMORY“ menu.

This menu enables you to manage the configuration memories as snapshots. In two consecutive screens, the 7 memory positions available for user-defined configurations are shown.

Each one of these memory positions stores all of the parameters in use at that time in each one of the console channel: gain, phase and balance configuration, “PROGRAM”, “AUDITION”,

“AUX1”, “AUX2” and/or “CUE” routing activation, configuration/activation of equalizers, filters and/or dynamics processes and channels activation/deactivation (ON/OFF). No fader position is stored, because these are set manually. The memory position also stores the activation of signals sending to control and studio monitoring (by means of the keys placed under the corresponding displays), but not the position of the 3 associated encoders.

The first of these screens displays the first 4 memory positions for user-defined configurations, and the second shows the following 3 memory positions. You can shift between these two screens by turning any of the associated encoders as you move through the complete list of snapshots stored at that time. The memory that is selected at any time is highlighted.

Each stored memory is identified by its name and the date on which it was created. The names of the memories are editable from the configuration software (see section 4.3.5 in this manual).

The options available through the contextual keys below the screen, from left to right, are:

• “BACK”: pressing this key allows you to return to the previous menu screen. No change you may have made is saved.

• “SAVE”: stores in the selected memory position the configuration of the console at that moment. The system will ask for your confirmation (in the screen that appears, you can confirm by pressing “SAVE” again or return to the memories list by pressing “BACK”).

• “LOAD”: allows you to load the configuration you stored previously in the selected memory position. The system will ask for your confirmation (in the screen that appears, you can confirm by pressing “LOAD” or return to the memories list by pressing “BACK”).

You can also create snapshots with different configurations from the configuration software. See section 4.3.5 of this manual.

• “STATUS”: allows you to access to the information regarding the routing and process

DSPs percentage of use. In case the working limit of any of them is exceeded the indication “OVL” (Overload) is shown.

3.4.2.

“SETUP“ menu.

Through the “IPSET” option in a contextual key, this menu enables you to display and modify the IP configuration associated with the two Ethernet ports available on the back panel of the equipment (“LAN” and “ETHERNET”: see section 2.2.2.2 of this manual) in the form of IP address, subnet mask (MASK) and gateway (GWAY). Only level 3 users are allowed to modify these parameters (the “SETUP” key is shown to other users but is not active).

IMPORTANT NOTE: the IP addresses of both Ethernet ports must not be configured into the same network.

For instance, if “LAN” port is configured with 172.31.34.1 IP address and

255.255.0.0 mask, the IP address of the “ETHERNET” port should be different from 172.31.x.x

(where x is any number between 0 and 255).

As in many other AEQ FORUM console submenus, the icon in the upper left-hand corner indicates that browsing and configuration are performed by using the associated rotary encoders.

From left to right, the three rotary encoders are associated with “IP”, “MASK” and “GWAY” fields respectively. Each one of these fields consist of 4 number separated by dots and named bytes.

A flashing cursor indicates the byte that is subject to be changed at that moment by turning the associated encoder. Pressing any of the 3 encoders allows you to change from one byte to the next one. This process is repeated from left to right until the IP address is complete, as well as the associated subnet mask and gateway.

The “OK” contextual key allows you to validate and save the changes, returning then to the previous screen. The “BACK” contextual key allows you to return to the previous screen without changes saving.

The “ETH”/”LAN” contextual key allows you to alternate the on-screen presentation and, therefore, to edition of the IP configuration parameters associated with the two network ports available on the rear panel of the unit: “LAN” and “ETHERNET”.

GAIN: configurable between -12dB and +12dB for line level inputs and between

-36dB and +19dB for mic level inputs. The field is configured with the default value of 0dB. Any modification of the initial value of this gain will illuminate the dedicated “GAIN” LED on the corresponding fader of the control surface (see section “2.1.1.5. Indicators of active processes” of this manual). o

PHASE: allows you to modify the input signal phase among +/+, +/-, -/+ and -/- for stereo signals, and among + and – for mono signals. o

BALANCE: enables you to modify the balance between the L and R channels in stereo signals. The operation of this indicator will activate the dedicated

“BAL” LED on the corresponding fader of the control surface (see section

“2.1.1.5. Indicators of active processes” of this manual).

By pressing this encoder

, you can configure the sending mode of the stereo input signal toward the stereo outputs that it is routed to. The options that appear successively when you press the encoder are: L-L (only the L input channel is sent to L and R output channels), R-R (only the R input channel is sent to L and R output channels) and R-L (the R input channel is sent to the L output channel and the L input channel is sent to the R output channel). If you press the enconder once more, it returns to the normal working mode (L-R).

3.4.3.1.1. Dynamics menu: Compressor/Limiter and Noise Gate.

COMPRESSOR / LIMITER:

Pressing the “DYNAM” contextual key from the advanced information menu of an audio input channel will give you access to the menu to configure the Compressor/Limiter.

Dynamics processors are used to modify the dynamic ranges of an audio signal to adapt it to specific needs or to produce certain sound effects. A compressor enables you to reduce the dynamic range of the signal. Your purpose may be to adapt a signal with a very broad dynamic range to a circuit that will not support such wide variations in level, or to generate certain sonority in a signal.

The “Compressor / Limiter” function acts as a “constant gain” compressor; that is, below the threshold, all input signals are amplified (or not amplified) equally, while above the threshold, the input levels are reduced to a greater or lesser degree according to the compression ratio.

If the compression range selected is the maximum, the function will act as a limiter in such a way that the signals that exceed the selected threshold at input will not exceed a certain level at output. For example, with a threshold = 0 dB, a gain of 10 dB and a compression ratio of 1:50, you will ensure that all the signals that exceed 10 dB at input will also be output at 10 dB, while the signals that are below the threshold will have an overall gain of 10 dB.

From top to bottom and left to right, the information displayed on the Compressor/Limiter configuration and control screen comprehends:

• “THR” (Threshold): this is the threshold above which the compressor will act. Signal levels that exceed this threshold will be affected by the compressor settings. The threshold range varies from -42dB to +22dB.

• “ATT” (Attack Time): this is the time it takes the compressor to react to an increase in the input signal. The shorter this time, the more sensitive the compressor will be to pulse signals, and the higher the action on this type of signals. With a long attack time, the compressor will not respond so well to pulse changes in the input signal. It ranges between 0.5 and 95 ms.

• “REL” (Release Time): this is the maintenance time during which the compressor keeps acting, even when the level of the input signal has fallen below the threshold. A long release time will maintain uniform compression, even when there are quick level fluctuations in the signal. A short time will enable the compressor to adapt more quickly to pulse fluctuations in the signal. It ranges between 10 and 9500 ms.

• “RAT” (Compression Ratio): this is the compression ratio. A ratio of 1:1 does not involve any variation in the signal, as the level of the input signal is maintained at the output. A ratio of 2:1 indicates that the level of an input signal which exceeds the threshold will be reduced to half at the output. The highest ratio available is 50:1, which will be used to implement signal limiters. The limiter must reduce all signals exceeding a certain level to that level.

• “G“ (Gain): this enables you to apply a general gain to the signal. This entails a general increase of the signal level, which will be especially noted at low input levels that are under the threshold set. A general increase in the level of the signal may generate saturation at the output, even when the signal is being limited. It ranges between 0 and

+40dB.

A cursor blinks over the fields placed on the left or on the right to indicate the fields that can be modified at that momento. To change from the one to another just press any of the three associated encoders. When you select the fields on the left, turning the first encoder allows you to change “THR”, the second one changes “ATT” and the third one changes “REL”; when you select the fields on the right, turning the first encoder allows you to change “RAT” and the second one changes “G” (the third one has no function in this case).

NOTE: To correctly set a limiter, a threshold between 0 and +22 dB should be selected, with a compression ratio of 50:1 and a gain of 0 dB.

The “COMP” contextual key enables you to activate the compressor whose parameters are shown at that time on the screen. The activation of the compressor is confirmed by the activation of the LED of the contextual key and the LED ”DYN” of the selected mixer channel

(see section “2.1.1.5. Indicators of active processes” of this manual). The “COMP” contextual key also enables you to return to the Compressor/Limiter menu when you are in the Noise Gate menu (in that case, the associated LED lights for a moment and then it turns off).

IMPORTANT NOTE: The dynamics process, and especially the Compressor/Limiter, requires either extensive experience or caution and time to check, while off the air, the result obtained on the signal. Without these precautions, you may generate sound effects that can be perceived as dirty sound, lack of definition, distortion and other defects in general.

By pressing the “NGATE” contextual key you will access the screen dedicated to the control and configuration of the Noise Gate for that input channel (the associated LED lights for a moment and then it turns off).

NOISE GATE:

A noise gate is a dynamics processor that lets signals through whose level exceeds a certain threshold, strongly attenuating the signal levels below that threshold and thus muting noise. It enables its user to eliminate extraneous noise from a signal source, whether it is background noise in the studio, in the case of a microphone, or the background noise generated by a playback device, for example, a tape.

From top to bottom and left to right, the information shown in the Noise Gate configuration and control screen is as follows:

• “ATT”: Attack Time. It ranges between 0 and 95 ms.

• “REL”: Release Time. It ranges between 0 and 9000 ms.

• “HOL”: Hold Time. It ranges between 0 and 2000 ms.

• “THR”: Threshold. It ranges between -72 and 0dB.

• “R”: Range. It ranges between 0 and 90dB.

A cursor blinks over the fields placed on the left or on the right to indicate the fields that can be modified at that momento. To change from the one to another just press any of the three associated encoders. When you select the fields on the left, turning the first encoder allows you to change “ATT”, the second one changes “REL” and the third one changes “HOL”; when you select the fields on the right, turning the first encoder allows you to change “THR” and the second one changes “R” (the third one has no function in this case).

AEQ FORUM


When establishing the settings, the threshold for the noise gate will be much lower than in the case of the compressor, as its operation is the opposite. The noise gate prevents the passing of lower levels of the signal that could be considered noise. Therefore, the range of settings is different. In addition, there is an additional parameter for noise gates, which is “Hold Time.” This is a safety period used to prevent the gate from accidentally closing if a signal is suddenly absent, for example, in speech.

In addition, the threshold must be adjusted to a level slightly higher than the level of the noise to be avoided. Thus, the threshold will be set at a very low level. Above the threshold, the noise gate does not act (unity gain), letting the rest of the signal through without processing it. The gate remains closed; i.e. when the signal surpasses the threshold level, the gate opens. The attack time is the time the gate takes to open (unity gain) when it receives a signal whose amplitude exceeds the threshold level; this time must be short to avoid cutting off the beginning of a sentence or song. The release time is the time the gate takes to close when the signal level falls below the threshold. The hold time is the minimum time during which the gate remains open; it is used to prevent the gate from closing when the signal level drops briefly—for example, when an announcer pauses while speaking. The hold time prevents the gate from opening and closing constantly in the presence of a signal whose level fluctuates in a range close to the threshold level.

The “NGATE” contextual key enables you to activate the noise gate whose parameters are shown at that time on the screen. The activation of the noise gate is confirmed by the activation of the LED of the contextual key and the LED ”DYN” of the selected mixer channel (see section

“2.1.1.5. Indicators of active processes” of this manual). The “NGATE” contextual key also enables you to return to the Noise Gate menu when you are in the Compressor/Limiter menu (in that case, the associated LED lights for a moment and then it turns off).

Pressing this contextual key for three seconds opens the cut-off frequency configuration menu: this configuration is accomplished by turning the first associated encoder and pressing the “BACK” contextual key to return to the previous screen once this parameter is configured (between 1000 and 20000Hz).

• “EQ”: allows you to activate the equalizer whose frequency response is shown at that time on the screen (the associated LED will light). This frequency response is controlled from the associated encoders by working from left to right on the base, mid-range and treble bands, respectively. The frequency deviation permitted ranges from -18dB to

+18dB (the default value is +0dB).

Pressing this contextual key for three seconds opens the equalizer advanced configuration menu, where 3 rows appears for base (“LOW”), mid-range (“MID”) and treble (“HIG”) bands respectively. You can change from one band to another by pressing any of the three associated encoders. In the selected band (a flashing arrow is displayed), you can change the central frequency (“F(Hz)” column) by turning the first encoder, the Q (“Q” column) by turning the second encoder and the gain (“G(dB)” column) by turning the third encoder. The “HPF”, “LPF” and “EQ” contextual keys in this screen allows you to activate filters and equalizer; the “BACK” key allows you to return to the graphic configuration screen.

• “FADER”: allows you to assign another input channel to the physical fader where this signal is currently found.

• “ROUTE”: gives you acces to the menu for control and configuration of the internal routing of the equipment.

3.4.3.1.3.1.

“FADER” menu.

This submenu is displayed as a list of all the inputs available in the system (except the ones that are yet assigned to a fader). You can make your selection by turning any of the associated encoders and then pressing any of them or the “OK” contextual key to confirm the selection that is highlighted at that moment.

The “BACK” contextual key allows you to return to the previous menu screen without changed the assigned signal.

3.4.3.1.3.2.

“ROUTE“ menu.

From this internal submenu you can manage the internal routing of signals in the console. You can access from the advanced information menu of an audio input channel and that submenu shows an alphabetical list of all of the outputs present in the console, followed by the internal summing buses (“Program”, “Audition”, “Aux1” and “Aux2”), the monitoring buses (“Cue”,

The operation of the contextual keys, from left to right, is as follows:

• “BACK”: pressing this key allows you to return to the previous menu screen (the changes you may have made are saved).

• “ADD”: enables you to create the cross-point toward the output signal or bus that is highlighted at that moment.

• “DEL”: enables you to delete the cross-point toward the output signal or bus that is highlighted at that moment.

• “OK”: pressing this key allows you to return to the previous menu screen (the changes you may have made are saved).

The routing toward the “Program”, “Audition”, “Aux1” and “Aux2” internal buses works in a different way depending on the assignment of the selected input to a fader or not:

- when the input is assigned to a fader and, in the previous list, you select “Program” bus

(for instance), when you press the “ADD” key the routing key (“PROGRAM” in this case) of the channel is activated (the associated LED is lighted). In the display, the crosspoint toward that bus appears for a moment and then dissappear. The “DEL” key has no associated function in that case (you must press the “PROGRAM” channel key to deactive that routing). If now you press the “ON” key of the channel, the cross-point appears now in the display (if you rise the fader, the “ON AIR” indicator will light); in that case, the “DEL” key allows you to deactive the routing toward that bus (the cross-point disappear and the “PROGRAM” channel key turns off).

- when the input is not assigned to a fader and, in the previous list, you select “Program” bus (for instance), pressing the “ADD” key is equivalent to set that input “ON AIR” (the cross-point appears and, if gain is not configured at its minimum value, signal is sent to that bus). The “DEL” key allows you to deactive that routing (the cross-point disappears).

4. CONFIGURATION SOFTWARE.

The AEQ FORUM console is ready for use once the mixer inputs and outputs have been properly connected.

The console is shipped with the Audio inputs/outputs modules as requested by each customer.

However, the name tags used for the channel audio inputs and outputs are generic (MIC 1,

ANA 3, DIG 5 ...) and routing and effects programmed are AEQ standards that are used for functional testing of the console, whereas these settings may not be entirely to the preferences of the client.

This equipment is delivered with a Configuration Software for Windows 2000, XP, Vista or 7.

This configuration software allows the user to modify the original configuration to its exact requirements at any time.

The auto run disk furnished with the console contains the executable file that installs the configuration software. You can find it going through the following screens:

Installing the application is simply a matter of executing this file and following the on-screen instructions as they come up.

There are two distinct parts in this submenu: the upper part is dedicated to the configuration of the Studio Room section and the lower to the Control Room section.

4.2.4.1.

“Studio Room Section“.

This section of “Monitoring Configuration” submenu lets you choose how the four keys under the display of the Studio Room Control and Monitoring section shall work, either in “Mixer” or

“Exclusive”. If the option “Mixer” is selected, the output bus associated with “Studio” monitor and headphones will act as a summing bus and therefore may be more than one of the four keys simultaneously activated, thus mixing the signals corresponding to each of the four keys on the studio monitor and headphones. On the other hand, in the “Exclusive” mode, this output bus will not act as a summing bus and therefore may not be more than one key activated at any given time (this effectively means that by pressing any of the four keys, the previously activated one will be disconnected from the summing bus and replaced by the new selection).

In this section you can also allocate the GPO physical outputs associated with Studio “OFF AIR” green light (indicates that there are no sources, typically microphones, activated in the studio room) and “ON AIR” red light (indicates that there are no sources, typically microphones, activated in the studio room). You can choose between the opto-coupled GPO´s (1 to 8) or the contact relay GPO´s (9 to 12): these last ones are recommended. See section 2.2.2.1 of this manual.

“Control Room Section“.

This section of “Monitoring Configuration” submenu lets you choose how the four keys under the display of the Control Room Control and Monitoring section shall work, either in “Mixer” or

“Exclusive”. If the option “Mixer” is selected, the output bus associated with “Control” monitor and headphones will act as a summing bus and therefore may be more than one of the four keys simultaneously activated, thus mixing the signals corresponding to each of the four keys on the studio monitor and headphones. On the other hand, in the “Exclusive” mode, this output bus will not act as a summing bus and therefore may not be more than one key activated at any given time (this effectively means that by pressing any of the four keys, the previously activated one will be disconnected from the summing bus and replaced by the new selection).

89

Dynamics processors are used to modify the dynamic ranges of an audio signal to adapt it to specific needs or to produce certain sound effects. A compressor enables you to reduce the dynamic range of the signal. Your purpose may be to adapt a signal with a very broad dynamic range to a circuit that will not support such wide variations in level, or to generate a certain sound in a signal.

The graph represents the variation produced in the different levels of the signal applied to this function. On the horizontal axis are the input levels, while the vertical axis shows output levels.

The “Compressor/Limiter” function acts as a “constant gain” compressor; that is, below the threshold, all input signals are amplified (or not amplified) equally, while above the threshold, the input levels are reduced to a greater or lesser degree according to the compression ratio.

If the compression range selected is the maximum, the function will act as a limiter in such a way that the signals that exceed the selected threshold at input will not exceed a certain level at output. For example, with a threshold = 0 dB, a gain of 10 dB and a compression ratio of 1:50, you will ensure that all the signals that exceed 10 dB at input will also be output at 10 dB, while the signals that are below the threshold will have an overall gain of 10 dB.

The available controls are:

• “THRESHOLD”: this is the threshold above which the compressor will act. Signal levels that exceed this threshold will be affected by the compressor settings. The threshold range varies from -42dB to +22dB.

• “ATTACK TIME”: this is the time it takes the compressor to react to an increase in the input signal. It ranges between 0.5 and 100 ms.

• “RELEASE TIME”: this is the maintenance time during which the compressor keeps acting, even when the level of the input signal has fallen below the threshold. It ranges between 0.01 and 10 s.

• “RATIO”: this is the compression ratio. A ratio of 1:1 does not involve any variation in the signal, as the level of the input signal is maintained at the output. A ratio of 2:1 indicates that the level of an input signal which exceeds the threshold will be reduced to half at the output. The highest ratio available is 50:1, which will be used to implement signal limiters. The limiter must reduce all signals exceeding a certain level to that level.

90

AEQ FORUM


• “GAIN“: this enables you to apply a general gain to the signal. This entails a general increase of the signal level, which will be especially noted at low input levels that are under the threshold set. It ranges between 0 and 40dB.

• “OK”: allows you to accept the created or edited configuration. A double confirmation is required.

• “Cancel”: allows you to reject the created or edited configuration. No change you may have made is saved.

4.3.4.2. Advanced configuration of Noise Gate.

From the initial screen of the pre-sets advanced information menu (“Digital Sound Processes”) you can configure and activate/deactivate the Noise Gate operation.

When you select the “Active” checkbox, the “Configure” button gets active and gives you access to the graphic display where the Noise Gate associated parameters can be modified.

A noise gate is a dynamics processor that lets signals through whose level exceeds a certain threshold, strongly attenuating the signal levels below that threshold and thus muting noise. It enables its user to eliminate extraneous noise from a signal source, whether it is background noise in the studio, in the case of a microphone, or the background noise generated by a playback device, for example, a tape.

The available controls are:

• “THRESHOLD“: determines the level above which signal is allowed through the gate.

• “ATTACK TIME”: the time for the gate to react to a signal that is exceeding the threshold.

• “RELEASE TIME”: the time that the gate should remain open once the signal exceeding threshold has disappeared.

• “HOLD TIME”: the time that the gate should remain open when the signal falls below the threshold.

• “RANGE”: the limit of dynamic range where created configuration will have effect.

91

AEQ FORUM


The threshold must be adjusted to a level slightly higher than the level of the noise to be avoided. Thus, the threshold will be set at a very low level. Above the threshold, the noise gate does not act (unity gain), letting the rest of the signal through without processing it. The gate remains closed; i.e. when the signal surpasses the threshold level, the gate opens. The attack time is the time the gate takes to open (unity gain) when it receives a signal whose amplitude exceeds the threshold level; this time must be short to avoid cutting off the beginning of a sentence or song. The release time is the time the gate takes to close when the signal level falls below the threshold. The hold time is the minimum time during which the gate remains open; it is used to prevent the gate from closing when the signal level drops briefly—for example, when an announcer pauses while speaking. The hold time prevents the gate from opening and closing constantly in the presence of a signal whose level fluctuates in a range close to the threshold level.

4.3.4.3. Advanced configuration of Equalizer.

From the initial screen of the pre-sets advanced information menu (“Digital Sound Processes”) you can configure and activate/deactivate the Equalizer operation.

The number of faders to configure depends on the number of 4 faders modules (FRCH) installed on the AEQ FORUM control surface (1, 2 or 3 FRCH modules can be installed, providing then with a maximum of 4, 8 or 12 channels) or AEQ GRAND FORUM control surface (4 or 5 FRCH modules can be installed, providing then with a maximum of 16 or

20 channels).

• “Talkback MIC”: allows you to configure the operation of the microphone input present in the common I/O’s section at the rear panel of the AEQ FORUM. When “Self-Control” checkbox is not activated, that input is configured only as an orders microphone toward studio or return for any open communication lines (this is a typical configuration for AEQ

FORUM when installed in a Studio/Control configuration). When “Self-Control” checkbox is activated, that input is configured as autocontrol microphone (it simultaneously works as orders microphone), so the host of the radio program is also the operator of the mixing console (this is a typical configuration when the Studio and

Control areas of the radio station are in the same room). Only when “Self-Control” checkbox is activated you can assign the talkback mic to a fader (when it’s not activated, the mic will not appear in the channels list).

•

“Studio”: section where you can configure the initial activation of one or several keys to send signal to monitor and headphones placed under the display of the studio monitoring section. The available options are “Program”, “Audition”, “Cue” and “Sel”

(when section is configured in “Exclusive” mode, you can activate only one key: see section 4.2.4.1 of this manual). “Sel Input” and “Sel Out” drop-down menus allows you to select a single input, output or internal summing bus to associate it initially with the

“SEL” monitoring key (that selection can be modify later by means of “HP/SOURCE” encoder).

• Name of the snapshot (test 1 in the example).

• Name of the channel (ANA 3 in the example).

• “Routing”: allows you to configure the initial activation (or not) of the quick routing keys that are available above each fader channel of AEQ FORUM control surface.

• “Balance/Panorama”: allows you to manage the initial balance or panoramic control for this input channel.

• “Buttons”: allows you to configure the initial status of the PFL sending button (“CUE”) and the CHANNEL ON/OFF keys of AEQ FORUM control.

• “Digital Gain”: allows you to control the initial input gain of the selected channel from -

12dB to +12 dB, by means of a graphical representation of a sliding fader.

• “Fader”: allows you to configure the initial virtual position of that channel fader.

IMPORTANT NOTE:

This configuration will take effect when that channel is not associated to a physical fader in the control surface; when it’s associated to a fader, the value corresponding to that physical fader position will be taken.

• When you move the corresponding fader in the control surface, that initial value updates.

• “Digital Sound Processes”: allows you to configure and activate/deactivate initially the available processes for that channel or, by means of “Load Preset” button, to select and load a previously created preset (see section 4.3.4).



4.3.5.2. Advanced configuration of outputs.

Within the “Configure Inputs & Outputs” advanced configuration screen, the right part of the screen shows the complete list of all the available audio output channels. Three columns are shown:
