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.

Source Formats on page 52.

Individual output settings are configured through the SSP 7.1 Setup and Control Software
(see Speaker Configuration Tab
Commands (see page 75):
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
Options and Usage on page 57.
RS-232 port (see figure 5, to the right) — 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).
