OVERVIEW 

The ART CX311 Stereo 2-Way Active Crossover with Subwoofer Output offers a superb level of 

sound quality and its straightforward user interface gives you quick and easy access to all of its 

features. Designed for home, club, or DJ system applications or live sound reinforcement, the CX311 

employs 24dB/ octave state-variable, fourth-order, Linkwitz-Riley filters. These filters guarantee in-

phase outputs at all frequencies. This ensures the proper acoustic summing of common signals from 

adjacent drivers in the crossover region. 
The CX311 is a stereo 2-way electronic crossover with an additional subwoofer output. Each 

crossover channel splits the frequency of an input signal into two separate signals, which may then 

be sent to amplifiers or other signal processing equipment in a sound system. The subwoofer output 

can be used to add punch to low bass audio. 
Each stereo channel features high and low output level and crossover frequency rotary controls, while 

the subwoofer channel features its own output level and crossover frequency rotary controls. A low 

cut switch for each channel may be used to remove unwanted subsonic audio that can damage 

amplifiers or speakers. Each stereo channel also includes a phase switch that can be used to detect 

or correct audio path connection errors. The rear panel features balanced XLR and 1/4” TRS input 

and output connectors. Power for the CX311 is internal. 
The ART CX311 Stereo 2-Way Active Crossover with Subwoofer Output has been carefully designed, 

engineered and manufactured to provide you with years of great sound and reliable service.
