The secret to making speakers sound great lies with the crossover you use. With the dbx 234xs Crossover, you'll get great performance, ultra-low-noise, rugged reliability and four decades of dbx knowledge and expertise in building the world's finest processors. The 234xs uses precision filters to separate the audio signal and direct the correct frequencies to your loudspeaker drivers. By directing only the specific frequency bands to each speaker driver the 234xs leaves your amplifiers free to use their full power on the usable signal eliminating distortion and giving your PA system a cleaner and better sound.
The dbx 234xs 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 XLR inputs and outputs.
Key Features:
2-/3-way stereo, 4-way mono operation
24dB/octave Linkwitz-Riley filters
XLR inputs and outputs
Low-frequency summing for subwoofer output
x10 range switch on both channels
40Hz highpass (low cut) filter both channels
Phase reverse switch on all outputs
Individual-level controls on all outputs
Stereo/Mono status LEDs indicate the selected mode
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.
