Analog audio output connectors
Connect audio devices, such as an audio amplifier or powered speakers, to these
3.5 millimeter, 5-pole captive screw connectors. These connectors output the tied
unamplified, line level audio (see figure13 to wire an output connector). Use the supplied
tie-wrap to strap the audio cable to the extended tail of the connector.

ATTENTION:
• For unbalanced audio, connect the sleeves to the ground contact. DO NOT
connect the sleeves to the negative (-) contacts.
• Pour l’audio asymétrique, connectez les manchons au contact au sol. Ne PAS
connecter les manchons aux contacts négatifs (-).
NOTES:
• The length of exposed wires is important. The ideal length is 3/16 inch (5 millimeter)
(see the audio input connector NOTES on the previous page for details).
• The audio that is output on these connectors is converted from the tied embedded
input signal or the analog audio input. This feature allows you to duplicate the
outputs while eliminating the need for extra receivers.
By default, the audio ties follow the video ties. Audio breakaway, which can be activated
via the front panel or under remote control if, in the DSP Configurator, the Output Signal
Source is set to From DSP (see Output signal processor chain, Volume controls on
page97), allows you to select from any one of the audio input sources and route it
separately from its corresponding video source (see Example 3: Remove a tie from a set
of ties on page32). You can also use an SIS Command (see page56) or the Product
Configuration Software (see Matrix Software on page70).
