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 (see figure 14 to wire an output connector).
These connectors output the tied unamplified, line level audio. 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 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 33). A tie with audio
breakaway can only be performed if, in the DSP Configurator, the Output Signal Source
is set to From DSP (see Output signal processor chain, Volume controls on page 103).
You can make audio breakaway ties with an SIS command (see page 58) or the Product
Configuration Software (see Matrix Software on page 73).
