ACS 8.2 Eight Input, Dual Output StereoMatrix Audio Controll Switcher
INSTALLATION
INSTALLATION GUIDELINES
Mounting:
The ACS 8.2 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 prefer-
ably away from sources of heat. We recommend before permanently
installing the ACS 8.2, you bench test and become familiar with the opera-
tion of the unit.
Power Supply Connection:
Install the 7-pin DIN power connector into the power receptacle on the
ACS 8.2. When ready, plug the power supply into the appropriate AC
receptacle.
Connecting The Audio Inputs, Outputs, Status Inputs And OC/Relays:
The input channels are numbered from 1 through 8 on the rear panel from
left to right. The ACS 8.2 interfaces to your audio equipment through
depluggable (Euro) screw terminals. Follow the legends for the desired
audio input and output connections, which appear on the rear side of the
printed circuit board and also on the layout drawing on the last page of this
manual. Remove each screw terminal, strip each conductor, insert the
conductor into the terminal and screw down the capture screw. The termi-
nals 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.
Connections can be made to the + and - outputs for balanced operation, or
to the + output and ground for unbalanced output operation.
It is recommended that all cables connected to the ACS 8.2 be looped
through ferrite cores to suppress RF. Surge protection with RF filtering
such as the Tripp Lite “ISOBAR 4” is also suggested for the power trans-
former. The purchase of an inexpensive uninterruptible power supply
(UPS) will provide back up in case of power outages. Check out our web
site for lightning protection links.
CAUTION!
In no case should
either the + or - out-
puts be connected to
ground.
The input impedance
is 20KW, 600W termi-
nation may be installed
on the connector.
CAUTION!
Installation of the ACS
8.2 in high RF environ-
ments should be per-
formed with care.
Shielded cable is sug-
gested for all control,
audio inputs and out-
puts. All shields should
be tied to the “CH
GND” terminal on
each channel. The sta-
tion ground should be
connected to the chas-
sis ground screw (CH1)
located behind J1 as
viewed from the rear.

tion devices, check out
