More sound to your amps and speakers 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.
Low/Mid: 45 to 960 Hz or 450 Hz to 9.6 kHz (x10 setting); Low/High: 45 to 960 Hz or 450 Hz to 9.6 kHz (x10 setting); Mid/High 450Hz to 9.6kHz (x10 setting)
Crossover Frequencies (Mono Mode)
Low/Low-Mid: 45 to 960 Hz or 450 Hz to 9.6 kHz (x10 setting); Low-Mid/High-Mid: 450 Hz to 9.6 kHz; High-Mid/High: 450 Hz to 9.6 kHz
Crossover Filter Type
Linkwitz-Riley, 24 dB/octave, state-variable
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.
