1. CONTROL SELECT: Both
microphone and aux input volume
can be adjusted from the front
panel controls or remotely from
a controller via the RS-232 Serial
Interface. This switch selects either
front panel control or RS-232
control. Front panel controls are
ignored during RS-232 operation.
2. RS-232 IN: A 9 pin connector
to connect the CAT 860 to an
external controller.
3. SPEAKER OUTPUTS (1–4): These
binding post connectors are used
to connect the CAT 860 to the
speakers. Depending on speaker,
all outputs may not be used.
*Note: Wiring to these terminals
should follow the Class 2 wiring
methods as outlined in the
National Electric Code.
4. CHARGERS: These jacks can
be used to charge the optional
LightMic or handheld mic as an
alternative to connecting them to
the REDMIKE cradle charger.
5. DC POWER: Plug the 24 V power
supply into this jack.

First, find a suitable location to set-up the amplifier. It is best to put the amplifier
in a stable location near the other equipment to be used. It can be set in a
cabinet, on a tabletop, or mounted on the wall with the included bracket.

The included wall bracket is
specifically designed to support the
CAT 860.

SET-UP & USE
1. LOCATION OF THE AMPLIFIER
Avoid Separated Set-ups
Components should be housed
together. Wires should be routed
back directly to the amplifier.

2. IR SENSOR/RECEIVER (ISR) INSTALLATION
Next, find a suitable location for the ISR. Poor location will cause substandard
performance of the CAT 860 Classroom Audio System. The ISR should be as
high as possible in the room – the ceiling is the best location, centered along the
longest wall in the room. When possible, use a conduit to protect the wires (not
included). Poor choices for placement are corners, on walls at heights lower than
7 feet (2 meters), or in places where the line of sight from the ISR to the receiver
is or could be obstructed.
Good placement
Conduit is Recommended

Avoid!

Once you find a suitable location for the ISR, follow these instructions to mount
it. There are different instructions for mounting depending on if the ISR will be
mounted to a suspended ceiling grid or secured to a wall / solid vertical surface.
1. Attach the bracket to the ceiling
tile grid (t-bar).
a. Slide the tabs onto the outsides
of the t-bar, starting with one
corner.
b. Attach the second tab around
the other side of the t-bar.
c. Repeat with the other side of
the bracket so it is connected at
all four points.
2. Slide the ISR onto the bracket until
it “clicks” into place.
a. Guide the mounting rails onto
the bracket, oriented as
pictured.
b. Once secure, the ISR locks into
place.
c. To remove the ISR, press the
release bar down and slide the
ISR off the bracket.
3. Uncoil the Cat 5 sensor cable.
Connect one end of the cable to
the ISR. Secure wire overhead and
route it back to the system.
4. Connect the other end of the Cat
5 sensor cable into the SENSOR
INPUT jack on the CAT 860
amplifier.

MOUNT BRACKET
1. Locate the speaker installation
instructions packed with your
speaker(s).
2. Follow instructions and mount
speaker(s).
3. Return to this manual to complete
the set up of your system.
A. Determine the location:
a. It should be located near a
power outlet.
b. Height should allow for access to
front control panel, but also be
in compliance with building and
ADA regulations.
B. Screw the bracket to the wall at
the two screw hole points with
the included hardware. Attach
to a stud when possible; use the
drywall mollies when studs are not
available.
C. Slide the CAT 860 onto the bracket
using the channel on the bottom
of the amplifier.
D. Secure the CAT 860 to the bracket
by tightening the screw on the
bottom.
E. Now that the CAT 860 is secure,
it can be slowly pulled out and
pivoted for better access to the
back panel. Push the CAT 860 back
in, to lock into place.
F. The power supply can be set
on the back of the bracket and
secured with ties if desired.
