Broadcast Tools®ACS 8.2 Plus Eight Input, Dual Output StereoMatrix Audio Control Switcher

DESCRIPTION

PRODUCT DESCRIPTION

The Broadcast Tools® ACS 8.2 Plus provides matrix audio switching of 8 stereo

inputs to 2 stereo plus 2 mono outputs. Any input assigned to output one has fading

capabilities. Matrix switching allows any/or all inputs to be assigned to any/or all

outputs. The ACS 8.2 Plus may be controlled via front panel switches, contact clo-

sures, 5-volt TTL/CMOS logic and/or the multi-drop RS-232 serial port (control via

USB or Ethernet with optional devices). Installation is simplified with plug-in

euroblock screw terminals.

PRODUCT FEATURES

• True matrix switching, any or all inputs may be assigned to any or all outputs.

Any input assigned to output one may be faded up, down or dimmed from either

the front panel, contact closures, 5-volt TTL/CMOS logic or the multi-drop RS-

232 serial port.

• Stereo LED VU meters with front panel output selection switch.

• Stereo headphone amplifier with front panel output selection switch, headphone

jack and level control.

• Internal silence sensors monitor both output channels. Each is equipped with

front panel LED indicators; separate SPDT SS alarm relays, adjustable alarm

delay and restore duration.

• Front panel input selection switches are provided for each input channel with

separate output indicator LED’s

• Power-up selection of inputs to outputs, mute or last source selected.

• 16 input GPI port (PIP or Remote Control) with LED indicator.

• Eight open collector channel status outputs or programmable via burst com-

mands.

• Eight SPDT relay outputs with multiplex function on output two. Programmable

via burst commands.

• Optional AGC function on each output channel.

• Logic functions via microprocessor and non-volatile memory

• Most configuration options via rear panel dipswitches.

• Multi-turn input and output level controls.

• Electronically balanced stereo inputs.

Broadcast Tools®ACS 8.2 Plus Eight Input, Dual Output StereoMatrix Audio Control Switcher

DESCRIPTION

FUNCTION DESCRIPTION

Front Panel:

The ACS 8.2 Plus is a 1-rack unit device (19”w x 1.75”h x 10”d). The front panel

supports fourteen selection switches, 25 LED indicators, headphone and LED VU

meter output selection switch, headphone jack and headphone level control.

Rear Panel:

Installation is simplified with euroblock pluggable screw terminals. The rear panel

host’s audio and control plug-in euroblock screw terminals, input/output trimmers,

multi-drop RS-232 modular connector and 5-pin DIN power supply connector.

Switches:

The front panel of the ACS 8.2 Plus contains selection pushbuttons for each input

channel. A mute switch is provided to turn off each audio channel. Fade up, down

and dim push buttons are provided for inputs assigned to output one. A push-push

switch is furnished for both VU meter and headphone monitoring selection. Input

channels may be programmed for the following operations:

• Overlap (default) - 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 – Multiple inputs at a time to any given output - Push once to connect input,

press again while holding down the mute switch.

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

that output.

LED Indicators:

The ACS 8.2 Plus’s front panel LED indicators provide operational display of the

following information:

• LED indicators for each input switch displaying which output channel the input

is assigned.

• The mute indicator LED is lit when all channels are off.

• Two 10 - LED VU meters are selectable between output channels.

• Two “SS” LED’s indicating when an output channel has drop below –37db.

• “PIP” Parallel Input Port (GPI) active, indicating any change with the 16 input

GPI ports.

• “Pwr/Ser” LED which indicates valid power and will flash when the serial RS-

232 port is receiving or transmitting serial data.

• Optional AGC LED’s. Each output AGC module will drive two LED’s indicat-

ing above/below the target level.

Broadcast Tools®ACS 8.2 Plus Eight Input, Dual Output StereoMatrix Audio Control Switcher

DESCRIPTION

Controls:

• Headphone and VU meter monitor switch to select which output channel is

monitored.

• Headphone jack

• Headphone level control

• Input, Output, Fade, Dim, Mute and Program push buttons

Audio Inputs:

Each of the 8 stereo inputs are balanced bridging (20KΩ) at a nominal line level of

+4dBu. Multi-turn level controls are provided for each channel.

Audio Outputs:

The ACS 8.2 Plus provides two selectable balanced stereo outputs. Two balanced

monaural outputs are also provided which follow their respective stereo outputs.

The stereo outputs are adjustable.

Stereo 10 – LED VU Meters:

The ACS 8.2 Plus contains LED VU meters selectable between the two output

channels.

Silence Sensors:

Each output channel has a detector that monitors the sum of each stereo channel.

The factory default delay is set at 10 seconds, with a threshold of -37 dB, while the

restore time is set at 10 seconds. Upon silence delay detection, the “SS-1 or SS-2”

SPDT relays close for the duration of the silence and the corresponding (SS-1 or SS-

2) LED is lit for duration of silence. Serial data is sent on either the loss or restora-

tion of audio. The sensor may be programmed for:

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

reached.

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

cleared (Restore).

Remote Control (GPI) Inputs:

Most front panel functions may be controlled with the 5-volt TTL/CMOS logic com-

patible, contact closure inputs.

PIP (GPI) Inputs:

The Parallel Input Port provides 16 parallel 5-volt TTL/CMOS logic compatible GPI

inputs. The inputs are pulled high to 5 volts through a 20KΩresistor and are acti-

vated 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).

Broadcast Tools®ACS 8.2 Plus Eight Input, Dual Output StereoMatrix Audio Control Switcher

DESCRIPTION

“Open Collector” Status Outputs, 8 Port Output Control

The ACS 8.2 Plus provides eight open collector status outputs. The status outputs

may be configured to operate in one of three modes:

• The status output follows the associated channel (multiplex applications).

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

• Software Control.

Relay Outputs, 8 Port Output Control:

The ACS 8.2 Plus contains 8 - SPDT relays. Each relay may be latched on, latched

off or momentarily turned on by a non-dedicated computer. The “pulse” time may

be set from 100msec to 9.9 seconds. The default pulse length is one-second.

8 SPDT relay outputs may be controlled by software. Each relay may be com-

manded to:

Multiplex “MPX” NON-software control. SW17-9 must be ON. Each relay fol-

lows the associated input channel selected to output two only.

WEBSITE:

product updates and

additional information.

Latch On Turns on and stays on (through power

failures) until turned off.

Latch Off Turns off and stays off (through power

failures) until turned on.

Momentary On Overrides latch; turns on for (default)

second, then latches off.
