Package Contents

The CR-1 Active Subwoofer Crossover is shipped from the factory with:

• Owner’s Manual

• IEC power cord (3-prong)

• 4 ea. RCA Shorting Plugs

•  2 ea. Rack-mounting ears. 

Installation requires the use  

of a 4mm hex wrench (not included)

Placement Considerations :

Table-Top

: The CR-1 ships from the factory configured as a “table-top” 

component, including rubber feet. To use it in table-top mode, simply place 

the unit in your equipment stand where it will be convenient to use and where 

cable management will be optimized (a significant number of audio cables will 

typically be connected to the CR-1). 

The CR-1 chassis is very robust and can easily support the weight of most 

source components and signal processors. However, we do not recommend 

placing heavier equipment, such as amplifiers or receivers directly onto the CR-1.

We also do not recommend placing the CR-1 directly on top of a power amplifier 

or receiver, as the heat generated by those components could affect the CR-1. 

Whenever possible, place the CR-1 on its own shelf or surface.

Rack-Mount: 

The CR-1 can be rack mounted in a standard 19-inch equipment 

rack, through the use of the included rack-mount accessory kit. When installed 

in a rack, the CR-1 occupies two (2) rack-units of space.

To convert the CR-1 for rack mounting: 

1. Unscrew the rubber feet from the bottom of the CR-1.

2.  Remove the 4 mm hex-head screws that secure the end covers of the front panel

3.  Using the same hex-head screws removed in Step 2, attach the rack ears to 

each end of the front panel, as shown in the diagram on this page.  

Do not overtighten.

4. CR-1 is now ready to be installed into an equipment rack.

5.  To protect the finish of the rack-mount ears, we recommend the use of 

nylon washers between the rack-mounting screws and the front surface of 

the rack-mount ears.

We do not recommend rack-mounting the CR-1 directly on top of a power 

amplifier or receiver, as the heat generated by those components could affect the CR-1.
