DBX 223XSV, Mode switch for stereo or mono, 40Hz high pass (low cut) filter both channels, Subwoofer Output, Linkwitz-Riley Filters, Range Switch (x10), XLR Connectors
The 223s from dbx is a dual channel, stereo 2-way or mono 3-way crossover. A crossover is essential for efficient PA operation because it filters the full band input signal into specific frequencies that match a speaker’s optimum frequency-reproduction range. This leaves the amplifier free to use its full power on the usable signal, eliminating distortion and delivering clear sound.
The unit features Linkwitz-Riley 24dB per octave filters, independent output gain controls for level matching, output phase inversion, 40Hz low cut filter, and optional mono summing of the low frequency (subwoofer) output. Quality components and meticulous attention to detail offers exceptional sound and rugged reliability, while exuding great precision from the solid “click” controls to the high quality XLR inputs and outputs.
Features:
• XLR balanced ins and outs
• Mode switch for stereo 2-way or mono 3-way operation
• Low frequency summed (subwoofer) output
• x10 range switch on both channels
• 40Hz high pass (low cut) filter both channels
• Phase reverse switch on all outputs
• Individual level controls on all outputs
• 24dB per octave Linkwitz-Riley filters (the professional standard)
• Stereo/Mono status LEDs indicate the selected mode
• dbx® 2 year parts and labor as standard
• CSA NRTL/C approved
• CE compliant

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-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.
