ACS 16.2 Installation and Operation Manual
INSTALLATION
Connecting the Audio Inputs and Outputs
The input channels are numbered from 1 through 16 on the rear panel from
RIGHT to LEFT as viewed from the rear. The ACS 16.2 interfaces to your audio
equipment through plug-in 5-position euro block screw terminals. Follow the leg-
ends on the rear of the unit for the desired audio input and output connections.
Before installing a wire, remove the plug-in 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 should be made to the + and - inputs for bal-
anced operation. For unbalanced inputs connect to the + inputs and connect the –
sides to ground using jumper wire. The input impedance is 20KΩ, if 600Ω termi-
nation is required, user supplied resistors may be installed on the connector.
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 on the
switcher or an external device.

Audio Input and Output Level Adjustment
Once the input and output connections have been made, the input levels can
be adjusted. The switcher is factory set for unity. Recommended input levels would
be in the range of 0 dBu to +8 dBu. Should input levels need to be changed, trim-
mers are accessible from the front panel. Each stereo input is labeled and has one
trimmer per channel.
Connecting the remote control/PIP (trigger) inputs
The ACS 16.2’s PIP inputs have two operation modes; PIP (triggers) and
remote control.
The operation mode is set by the switch number 8 on the Options dipswitch
(SW3-8) located on the ACS’s rear panel. When SW3-8 is OFF the unit is in remote
control mode and when SW3-8 is ON the unit is in PIP (‘triggers”) mode. The
PIP/remote control connections to the switcher are found on the bottom row of the
18-positon euro-block connector TB10. Each channel is pulled high (5-volts)
through a 20K resistor and is considered ON when connected to ground (pulled low.)
In PIP (“triggers”) mode (SW3-8 ON) the inputs supply status to any serial
polling device (when the unit ID is set to 0 (ZERO) no polling of inputs is required).
Response time is set for 50ms, but may be configured from 40ms to 2.54 seconds.
For information on the PIP serial status commands and syntax refer to the serial
burst mode commands section of this manual.
In remote control mode (SW3-8 OFF) there are remote control inputs for
each of the 16 audio input channels along with an output 2 (OP2) modifier input. If
an input channel is off a momentary closure to ground on its remote control input
will turn it on for output 1.
