Active Crossover

The dbx 234s is a dual channel crossover with all the features you would expect from a professional product. It features Linkwitz-Riley 24dB per octave filters, independent output gain controls for level matching, output phase inversion, 40 Hz low cut filter, and optional mono summing of the low frequency (subwoofer) output. Everything in the design exudes great precision from the solid "click" controls to the high quality 1/4" TRS inputs and outputs.

Low cut Switch Activates 40 Hz Butterworth, 12 dB/octave high-pass filter, one switch per channel.
Phase Invert Switch Inverts the phase at the output, one switch per output.
x1 / x10 Switch Multiplies the low-high(mono: low/mid and high/mid) crossover frequency range of the front-panel markings by a factor of 1 or 10, one switch per channel.
Mode Switch Selects stereo/mono and 2/3/4-way operation
LF Sum Switch Selects normal (stereo) or mono-summed low frequency operation and disables Ch 2’s low output phase invert LED to indicate that this output is not operational in the LF sum mode.
