Extron Electronics SSP 7.1 User Guide - Manual (Page 11)

NOTES: • 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.
For more information about input formats, see “Front Panel Features and
Operations” on page 6 and the “Source Formats” section on page 61.

Figure 3. Audio Outputs
Individual output settings are configured through the SSP 7.1 Setup and Control
Software (see page 30) or SIS commands (see page 86):
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 66.

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).
