A rack mount active crossover may be configured in either stereo 2- way or mono 3-way mode. Designed to be used in a multi-amplifier, multi-speaker PA or front of house system, it accepts a balanced line input via XLR connectors on the rear panel. Output connectors are all balanced XLRs.

The crossover frequencies can be adjusted from 45 to 960Hz, with a x10 scale selector allowing adjustment from 450Hz to 9.6kHz. Gain controls are provided for inputs and for the separate low, mid and high bands. This flexibility allows the system output to be tuned, using the crossover, to suit the speaker system in use and the venue acoustics. Having established as linear a response as is possible by adjusting the crossover filter points and gains, an equaliser such as the A 5330 can be used to fine tune the system.

A separate subwoofer output socket and gain control is provided, with the subwoofer low-pass point adjustable from 20Hz to 200Hz. This output is available in either 2-way or 3-way mode. When using the subwoofer output, a “low cut” switch enables all frequencies below 40Hz to be cut from the other crossover outputs. In a multicabinet system this can be employed to protect the mid/bass drivers from damage caused by powerful sub-bass signals. To provide further signal adjustment, phase invert switches may be used to reverse the polarity of the low, mid or high output signals.
