Extron electronics SSP 7.1 User Manual page 11

NOTE: The length of the exposed wires in the stripping process is critical. The ideal
length is 3/16 inches (5 mm). Any longer and the exposed wires may touch,
causing a short circuit between them. Any shorter and the wires can be easily
pulled out even if tightly fastened by the captive screws.
Do not tin the wires. Tinned wire does not hold its shape and can become
loose over time.

Audio Outputs
Individual output settings are configured through the SSP 7.1
Software (see page 30)
Mono — Output is through the center channel only but can be reconfigured to be
output through the left and right front channels. In the absence of a center channel,
mono is also output through the left and right front channels.
2-channel (stereo) — Only the front left and front right channels are used.
2.0 to 2.1 surround configurations — Audio is output through front left and front
right channels with (2.1) or without (2.0) a subwoofer.
3.0 to 3.1 surround configurations — Audio is output through front left, front right,
and center channels with (3.1) or without (3.0) a subwoofer.
4.0 to 5.1 surround configurations — Audio is output through a combination of front
left and right, left and right surround, center and subwoofer channels.
6.0 to 6.1 surround configurations — Adds a back channel to 5.0 or 5.1
configurations. The back left channel receives the sixth channel information and serves
as the center back speaker in this configuration.
7.0 to 7.1 surround configurations — Both the back left and right channels are
active. Listening modes designed for 6.1 channel outputs pass the same signal to both
the back left and right channels. Listening modes designed for 7.1 channel outputs pass
separate signals to each channel to produce a stereo back sound effect.
For more information about speaker configuration and output formats, see the
"Listening Mode Options and Usage" section on page

RS-232 port — The SSP 7.1 can be configured using the SSP 7.1 Setup and
Control Software or SIS commands, using this 3-pole captive screw connector
(or the 2.5 mm Tip Ring Sleeve (TRS) mini jack plug on the front panel).
