PRODUCT DESCRIPTION

The Broadcast Tools® SS 16.4 provides matrix audio switching of 16 stereo inputs to 4 stereo

plus 4 monaural outputs. Matrix switching allows any/or all inputs to be assigned to any/or all outputs.

The SS 16.4 may be controlled via front panel switches, contact closures, 5-volt TTL/CMOS logic and/or

the multi-drop RS-232 or RS-485 serial port. Installation is simplified with removable screw terminals

(Euro).

PRODUCT FEATURES

PRODUCT DESCRIPTION

Front Panel:

The SS 16.4 is a 2 - RU device (19”w x 3.50”h x 10”d). The front panel supports 23 selection switches

and 72 LED indicators.

Rear Panel:

Installation is simplified with pluggable screw terminal connectors. The SS 16.4 may be pre-wired and

installed in minutes. The multi-drop RS-485 and RS-232 modular connection and a 7 pin “DIN” power

connector is provided for the supplied “Lump in the Line” power supply.

Switches:

Twenty-three pushbutton switches (The “PGM” switch is hidden) that may be used to mute or select

audio inputs and output channels. Sixteen macros may also be programmed and selected. 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,

again to disconnect.

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

LED Indicators:

The SS 16.4’s 72 front panel LED indicators provide operational display of the following information:

•Four indicators per input channel display which output channel the input is connected.

•Unit power and serial data activity.

•“PIP” Parallel Input Port active, indicating any change with the 24 input “Pulse Stretcher” ports.

•Four audio activity LED’s and detectors.

•SS 16.4 selected or active indicates that the multi-drop RS-232 or RS-485 serial port has been

addressed.

PRODUCT DESCRIPTION

Controls:

Audio Inputs:

Each of the 16 stereo inputs are balanced bridging (20KΩ) at a nominal line level of +4dBu. Sufficient

gain is provided for unbalanced consumer level products. Multi-turn level controls are provided for each

channel. Terminating resistors may be added to the connector, if needed.

Audio Outputs:

The SS 16.4 provides four selectable balanced stereo outputs. Four balanced monaural outputs are also

provided which follow their respective stereo outputs.

“ACT” Audio Activity Sensor:

The SS 16.4 contains individual audio activity sensors, which may be used as silence sensors for each of

the four stereo output channels. For each channel, a detector monitors the sum of each stereo channel.

The factory default time delay and restore delay is set at 10 seconds, with a fixed signal threshold of -

32dB. Upon silence detection for the user-selected time, the “ACT” indicator is extinguished for the

duration of silence and serial “ACT” status is sent. When audio returns and the restore time delay has

expired, the front panel “ACT” led will illuminate and serial “ACT” status is sent. The “ACT” may be

programmed for:

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

•Number of seconds of audio presence after an alarm state before the “ACT” led illuminates.

PIP Input:

The Parallel Input Port (GPI) with the Programmable Pulse Stretcher provides 24 pulse-stretched parallel

5-volt TTL/CMOS compatible inputs. The inputs are pulled high to 5 volts through a 20KΩresistor and

are activated by pulling the input to ground. These inputs supply status to any serial polling device (when

the unit ID is set to 0, no polling of inputs is required). For all PIP inputs a pulse of specified minimum

input duration (000 to 2.55 Seconds) causes the status to go true until the end of the input pulse. The pulse

width may vary between the specified value and 10 ms less than that value. This allows the polling

computer more time to detect an input change.

PRODUCT DESCRIPTION

“Open Collector” Status Outputs, 16 Port Output Control

The SS 16.4 provides sixteen 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.

•Burst mode control

Relay Outputs, 8 Port Output Control:

The SS 16.4 contains 8 spst (normally open) relays. Each relay may be latched on, latched off or pulsed

on by serial burst commands. The relay “pulse” time may be set from zero to 9.9 seconds. The default

pulse length is one second.

Serial Communication:

The SS 16.4’s serial communication may be configured for either multi-drop RS-232 or RS485, allowing

up to 8 - SS 16.4’s on the same computers serial port. 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 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:

User Programming:

The SS 16.4 programming is stored in non-volatile memory. Configurations are set with selection

dipswitches and computer commands.
