Function Description

Front Panel

The SS 4.4 is a 1-rack unit device (19”w x 1.75”h x 6.0”d). The front panel supports

19 selection switches, 24 LED indicators, headphone, powered monitor and LED

VU meter selection switch, ¼” T/R/S jack and level controls.

Rear Panel

Installation is simplified with plug-in euroblock screw terminals. The rear panel hosts the connectors, input/output level trimmers, “OPTIONS” Dip-switch, multidrop RS-232 modular connector and 5-pin DIN universal power supply connector.

Switches

The front panel of the SS 4.4 contains separate input selection pushbuttons for each of the four output channels.

A mute switch is provided to turn off each audio channel, while the macro switch allows the user to program or select up to 16 macros.

A front panel monitor selection switch, level controls and led indicators are furnished for powered monitors, LED VU meters and headphone monitoring of the four output channels.

The input channels may be programmed for the following operations:

• Overlap - Overlap one audio source with another while the button for the second source is held down. Both channels will be fed to the output until the second button is released, at which time the first audio source will be switched off.

• Mix - May connect more than one input at a time to any given output - Push once to connect input, then hold the MUTE switch and press the selected input again to disconnect.

• Interlock - Connecting one input to any output disconnects all other inputs from that output

LED Indicators

The SS 4.4’s front panel LED indicators provide operational display of the following information:

• Led indicators on each input channel switch.

• Four “MON” led’s displaying which output channel is currently being monitored.

• The “MACRO” led indicator will flicker when activated.

• The “MUTE” indicator is lit when all channels are off.

• The “ACT” led indicating audio activity for output channel one. Trip level set at –25db.

• One “SS” led indicating when output ONE has a silence sensor alarm.

• “PIP” (Triggers) active. Flickers, indicating any change with any of the 16 trigger inputs.

• “PWR” led which indicates valid power and will flash when the serial RS-232 port is receiving or transmitting data.

Controls

Front panel powered monitor level control.

Front panel headphone level control.

Audio Inputs

Each of the four stereo inputs are balanced bridging (20K

Ω) at a nominal line level of +4dBu. Ample system gain is provided to accommodate most unbalanced consumer level products. Multi-turn level trimmers are provided for each channel.

Audio Outputs

The SS 4.4 provides four balanced low impedance stereo outputs. The outputs may be adjusted with the multi-turn trimmers.

Silence Sensor

The SS 4.4 contains a silence sensor for stereo output one. A detector monitors the sum of stereo output one. The factory default delay is set at 10 seconds, with a threshold of -25 dB, while the restore time is set at two seconds. Upon silence delay detection, the “SS” led will illuminate and the SPDT SS relay will close for the duration of the silence. The sensor may be programmed for:

• Number of seconds of silence that must be present before an alarm state is reached or terminated.

• Number of seconds that valid audio must be present before an alarm state is cleared.

PIP (Trigger) Inputs

The 16 input “PIP” (GPI/Triggers) are used to monitor closures and pass that information back to the control computer. Response time is set for 50ms, but may be configured from 40ms to 2.54 seconds. The inputs are pulled high (5 volts through a

20K

Ω resistor) and activated by forcing the input to ground. These inputs supply status to any serial polling device (when the unit ID is set to 0 (ZERO), no polling of inputs is required).

WEBSITE:


“Open Collector” Status Outputs, 4 Port Output Control

The SS 4.4 provides four open collector status outputs. The status outputs may be configured to operate in one of three modes:

The status outputs follow the associated channel.

The status outputs a one-second pulse when the associated channel is selected.

Software control

Relay Outputs, 4 Port Output Control

The SS 4.4 contains four SPDT relays. Each relay may be latched on, latched off or momentarily turned on by an attached control computer. The “pulse” time may be set from 100 msec to 9.9 seconds. The default pulse length is one-second. The relays may be set for “MPX” mode. In the “MPX” multiplex mode, the relay follows the associated input channel assigned to output two.

Mounting

The SS 4.4 is designed to be rack mounted in a standard 19” rack. It should be mounted in an area that is accessible from the rear and preferably away from sources of heat. We recommend before permanently installing the SS 4.4, you bench test and become familiar with the operation of the unit.

Power Supply Connection

Insert the universal AC input, multi-voltage DC switching power supply’s 5-pin DIN connector into the power receptacle on the rear panel of the SS 4.4. When ready, plug the power supply into the appropriate AC receptacle.

CAUTION! Only use the power supply provided with this product.

Connecting the audio inputs, outputs and remote control devices

It is recommended that all cables connected to the SS 4.4 be looped through ferrite cores to suppress RF. Surge protection with RF filtering such as the Tripp Lite “ISO-

BAR 4” is also suggested for the power transformer. The purchase of an inexpensive uninterruptible power supply (UPS) will provide back up AC in case of power outages. Check out our web site for lightning protection links.

Connecting the audio Inputs and Outputs

The input channels are numbered from 1 through 4 on the rear panel from left to right. The SS 4.4 interfaces to your audio equipment through plug-in euroblock screw terminals. Follow the legends for the desired audio input and output connections, which appear on the rear of the unit. Before installing a wire, remove the plugin euroblock screw terminal and turn each capture screw fully counterclockwise.

Strip each conductor to a length of 0.25” and insert the conductor fully into the terminal. Turn the capture screw fully clockwise to secure the conductor.

The terminals accommodate wire sizes from 16 - 28 AWG solid or stranded wire.

Connections may be made to the + and - inputs for balanced operation, or to the + input and grounding the - side for unbalanced input operation. The input impedance is 22K

Ω, 600Ω terminations may be installed on the connector if required.

CAUTION!

Installation of the SS

4.4 in high RF environments should be performed with care.

Shielded cable is suggested for all control, audio inputs and outputs. All shields should be tied to the “GND” terminal on each channel. The station ground should be connected to the chassis ground screw (GND) located on each side of the chassis as viewed from the rear.

For lightning protection devices, check out www.polyphaser.com

and www.itwlinx.com.

Connections can be made to the + and - outputs for balanced operation, or to the + output and ground for unbalanced output operation.

CAUTION!

In no case should either the + or - OUTPUTS be connected to ground.

Adjusting Input and Output Levels

Once the input and output connections have been made, the input levels can be set.

The switcher is factory set for unity, but has about 10 dB of system gain.

Recommended input levels would be in the range of -6 dBu to +10 dBu. Should input levels need to be changed, they are accessible from the rear panel. Each stereo input and output is labeled and have two trimmers per stereo channel.

Input Channel Expansion

Input expansion may be accomplished by connecting a shielded cable between the first units EXT 1+ input terminal and the second units unbalanced output. The shield should be connected to the ground terminal. Follow the same procedure for the EXT +1 right channel. The above example provides 8 inputs, with the first switcher providing the main output.

Connecting the RS-232 Serial Port

The multi-drop RS-232 transceiver always switches between transmit and receive mode, unless the unit ID is zero. In that case, the unit will always leave the RS-232 transceiver enabled. Use the provided modular (S9) 9-pin D-sub connector adapter and reversed modular cord to connect the SS 4.4’s serial connector to your serial port.

Connecting Two SS 4.4’s To A Single Computers Serial Port

Multiple SS 4.4’s may be cascaded serially to operate from the same serial port. The first step is to assign unit ID’s to each SS 4.4. One suggestion is to assign unit ID 1 to the first SS 4.4 and unit ID 2 to the second switcher. The second step is to parallel the serial ports of the SS 4.4’s. Plug the male end of the duplex modular adapter into the supplied female (S9) DB-9 to RJ-11 adapter, then attach the supplied modular line cords into each of the duplex modular adapter receptacles (Radio Shack Cat

No. 279-0357) and the other ends into each SS 4.4 modular receptacles. See the diagram below. NOTE: Three or more SS 4.4’s may be daisy chained by using the above description and a Radio Shack Cat No. 279-0410, 5-jack modular adapter.

The command to enter menu mode is: *0MM. The menu mode displays certain parameters, and allows for the control and/or configuration of most switcher functions.

Serial Burst Mode Commands

Burst mode allows a computer or ASCII terminal to control and interrogate the unit.

This section defines all burst mode commands. Each burst mode commands starts with an asterisk (*). Next is a single decimal digit that corresponds to the unit (ID) address 0-3. Following that are one or more ASCII characters specifying the command. No carriage-return or line-feed is required to terminate the command except for those few commands of variable length, if the maximum length is not sent. If the command requested a response, the response will consist of an upper case “S”, followed by the unit address, and then the specific response. If acknowledgements are enabled, successful commands are responded to with “RRR” while errors get an

“EEE” response. The syntax of each command is given below. The syntax shows the command exactly as it should be sent, except that lower case characters represent values that should be substituted: e-mail: [email protected] voice:

Set-up Commands

*uMM - Open up Menu

*uCEx - Enable Error and Good Responses - Where x = Y to enable and N = disable.

In this mode, when a command is sent that is in error, the unit will reply (possibly before receiving the entire command) with “EEE.” If the command is sent correctly, the unit will reply with “RRR.”

*uCDEF - Set factory defaults

*uCIIttt - Set “PIP” Programmable Pulse Stretcher Input Duration = ttt: 000 –> 255 hundredths of seconds (255 = 2.55 Seconds)

*uCLx - Lock Front Panel if x is “L”. Unlock Front Panel if x is “U”

*uCPR - Power up audio state: Restore audio from power up state

*uCPS - Power up audio state: Save power up state

*uCRtt - Set Relay Momentary Pulse Length – tt: 00-99 for 00 –> 9.9 Seconds

Set-up Commands

*uCSAtttt - Set silence sensor time delay to tttt seconds (0002 – 9999), 0000 = OFF

*uCSBtttt - Set silence sensor restore delay to tttt seconds (0002 – 9999), 0000 =

Information Retrieval Commands

*POLL - Respond with unit (ID) address in appropriate time slot. If there are multiple units on the line, each will respond with a different delay after receipt of this command.

*uSL - Send Audio Status: SuLo,x,x,x,x<CR><LF>. “u” is unit ID, “o” is output, and “x” is “1”for connected; “0” for not connected for each respective input.

*uSPii - Send single input (GPI) PIP status. Response is “SuP,ii,x” where “x” is 0 if the corresponding input is high, 1 if low.

*uSPA - Send ALL input (GPI) PIP status. Response is:

“SuP,A,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x<CR><LF > where input 0 is first and input 15 is last. “x” is 0 if the corresponding input is high, 1 if low.

*uSO - Send status of all Open Collectors. Response is: SuO,x,x,x,x<CR><LF> (0

= OFF).

*uSR - Send status of all relays. Response is: SuR,x,x,x,x<CR><LF> (0 = OFF).

*uSS - Send status of silence sensor: SuS,a<CR><LF> a = 0 (not silent), 1 = silent
