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 (–)
