Analog audio input connectors
Connectors are included with the matrix switcher, but you must supply the audio cable. See
figure 23 to wire a connector for the appropriate input type. Use the supplied tie-wrap to
strap the audio cable to the extended tail of the connector. High impedance is generally over
800 ohms.

Captive Screw Connector Wiring for Audio Inputs
NOTE:
The length of exposed wires is important. The ideal length is 3/16 inch (5 mm)
A mono audio connector consists of a tip and sleeve. A stereo audio connector consists of
a tip, ring and sleeve. See figure 24 to identify the tip, ring, and sleeve parts of the connector
when you are making connections for the matrix switcher from existing audio cables. The
ring, tip, and sleeve wires are also shown on the captive screw audio connector diagrams,

Typical Audio Connectors
The level for each analog audio input can be individually set via the front panel or remote
control to ensure that the level on the output does not vary from input to input (see
and Adjusting the Input Audio Level
on page 48). You can also use an SIS command
(see page 93), the XTP System Configuration software (see the XTP System Configuration
help file, or the HTML pages (see
Changing the input gain and attenuation
page 139).
