OVERVIEW The ART CX310 Stereo 2-Way/ Mono 3-Way Active Crossover is a perfect addition to any sound reinforcement system. Designed for PA and fixed-installation applications, the CX310 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.
INSTALLATION The ART CX310 may be used in a wide variety of applications and environments. Enclosed in a 1U (1.75 inches high) rack-mountable, all-steel enclosure, the unit is designed for continuous professional use. The depth is 6.5 inches, exclusive of the power cord. Mounting location is not critical. However, for greater reliability, we recommend that you not place the unit on top of power amps or other sources of heat.
OPERATION FRONT PANEL CONTROLS POWER SWITCH The POWER switch applies and removes power to the unit. Make sure that all equipment after the CX310 is either off or the outputs are turned all the way down before turning the CX310 on or off. CLIP INDICATORS Separate HIGH and LOW CLIP indicators are provided for each channel of the CX310. These indicators will light at approximately 3dB before clipping occurs in any stage of the channel.
These controls attenuate only (there is no gain). In most cases you would set them to 0 (fully clockwise). You can use these controls to prevent overdriving the inputs of your amplifiers or to compensate for variations in amplifier gain or speaker efficiency. Additionally, you can use these controls to balance the level between highs and lows in your system.
APPLICATIONS The following guidelines refer to a P.A. system, but the same basic ideas apply to a home recording setup or a Hi-Fi system. Typical Setup For a stereo 2-way system, separate high frequency (horn or tweeter) and low frequency (bass or subwoofer) speaker cabinets are used for each channel (left and right) of the stereo sound system and are driven by their own power amplifiers.
