4. Signal Outputs

Connect these output jacks to the input jacks  

of studio monitors. Like the inputs, there are two  

types of output connectors to choose from for  

the left and right outputs: 1/4" balanced or unbalanced 

or unbalanced RCA. Since these are connected together 

electrically, do not connect more than one pair of cables 

at a time to the output jacks.

The frequency range depends on where the crossover 

level is set.

These output jacks are wired the same as the input 

jacks as seen on the previous page.

5. Input Level Knob

The CR8S-XBT subwoofer expects a line-level signal 

at its input. Use this control to adjust the sensitivity  

of the input section (from Off to Max) according to  

the signal strength at its input.

6. Sub Output Level Knob

This knob adjusts the subwoofer’s overall output  

level (from Off to Max). Balance the subwoofer  

to your desired low-frequency output level  

and adjust the crossover to your desired setting.

7. Crossover Knob

The CR8S-XBT crossover allows you to choose  

a crossover frequency for studio monitors ranging  

from 40 Hz to 180 Hz for optimal sound. Adjust  

to what sounds best to your ears.

8. Polarity Switch

This switch – when left – sends a normal (0˚)  

polarity of the signal into the subwoofer amplifier.  

It has no effect on the signal at the outputs.

This switch – when right – reverses the polarity  

of the signal going into the subwoofer amplifier by 180˚.  

It has no effect on the signal at the outputs.

There is no right or wrong setting for this switch.  

Listen to the overall blend of the subwoofer with  

the rest of the system and select the switch position 

that gives you the best sound. In fact, your system  

may vary when positioned differently. Don’t be afraid  

to experiment with the position of the polarity switch. 

See page 10 for more information.

9. CRDV Jack

Plug the 1/4" connector of the included CRDV volume 

controller to this jack for remote control of the overall 

and subwoofer levels.

CRDV: Features

Included with your CR8S-XBT subwoofer is a CRDV 

volume controller. With it, you are able to control the 

overall volume level, as well as the subwoofer level...  

all without having dig around behind the subwoofer!

There are three control knobs:

•  The top control knob adjusts the overall volume  

of the system. Rotate clockwise to turn it up and 

counter-clockwise to turn it down... although we  

don’t know why you would want to turn it down!

•  The middle control knob adjusts the subwoofer 

volume. Rotate clockwise to turn it up and counter-

clockwise to turn it down.

•  The bottom control knob adjusts the settings  

of the sun. Rotate clockwise to turn the heat up  

and counter-clockwise to turn it down.

Hey sports fans, in a pinch, the CRDV can also 

double as a hockey puck.
