Mono Audio (local audio) outputs — Connect audio devices, such

as an audio amplifier or powered speakers, to these four or eight 3.5 mm,
5-pole captive screw connectors. These connectors output the selected
unamplified, mono line level audio. See figure 10 to wire an output
connector. Use the supplied tie-wrap to strap the audio cable to the extended tail of the
connector.

Captive Screw Connector Wiring for Audio Output

CAUTIONS:

For unbalanced audio, connect the sleeves to the ground contact.

DO NOT connect the sleeves to the negative (-) contacts.

The length of exposed wires is critical (see the

CAUTIONS

on page 14

for details).

Matrix sizes 1616 and smaller have four local audio outputs.
Matrix sizes 1632 and larger have eight local audio outputs.
These outputs are always outputs 1 through 4 (or 8), with the same inputs tied to them
as to TP outputs 1 through 4 (or 8).

NOTES:

The audio that is output on this (these) connector(s) is converted from

the tied proprietary TP input signal or the local audio input. This feature
allows you duplicates of the outputs while eliminating the need for extra
receivers.

When an input that is configured as RS-232 is switched to a local audio

output, the output is muted to prevent RS-232 noise on the audio
output.

The volume level for each local output can be individually set via the front panel or
remote control (see the “

Operation

” section, the “

Programming Guide

” section, the

Matrix Software

“ section, and the “

HTML Operation

” section).

By default, the audio ties follow the video ties. Audio breakaway, which can be activated
via the front panel or under remote control, allows you to select from any one of the
audio input sources and route it separately from its corresponding video source (see the

Operation

” section, the “

Programming Guide

” section, the “

Matrix Software

section, and the “

HTML Operation

” section).
