CR8S-XBT: Rear Panel Features

1. Power Connection and Fuse

Connect the power cord to this
IEC socket securely, and plug
the other end into a live AC outlet.
Make sure the AC outlet has
the correct voltage indicated
below the IEC socket.
Disconnecting the plug's
ground pin is dangerous.
Don't do it!
The fuse is located behind the
fuse cover, at the bottom of the IEC
socket. See the "Troubleshooting"
section on page 11 for information
about replacing the fuse.

2. Power Switch

Press this switch up to turn
the CR8S-XBT subwoofer on.
Make sure the input and output
level knobs are off [fully counter-
clockwise] before turning it on.
The ring surrounding the
Running Man logo on the front
panel illuminates white when
the CR8S-XBT is plugged into
an AC outlet and the power
switch is turned on.
Press this switch down to turn
the CR8S-XBT subwoofer off.

3. Signal Inputs

Connect the line-level signal from a computer, mixer,
or other signal source to one pair of these input jacks.
There are two types of input connectors to choose from:
1/4" line-level signals driven by balanced or unbalanced
sources or RCA line-level signals driven by unbalanced
sources. Since these are connected together
electrically, do not connect more than one signal
at a time to the input jacks.
A balanced signal provides better noise rejection
and is the preferred method, especially if using a cable
longer than 20 feet (6 meters).
They are wired as follows, according to standards
specified by the AES (Audio Engineering Society):
1/4" TRS Balanced Mono Wiring:
Sleeve = Shield (Ground)
Tip = Hot (+)
Ring = Cold (–)

To connect unbalanced lines to these inputs,
use a 1/4" mono (TS) phone plug, wired as follows:
1/4" TS Unbalanced Mono Wiring:
Sleeve = Shield (Ground)
Tip = Hot (+)
The unbalanced RCA plugs are wired as follows:
