Phase Invert Switch Inverts the phase ## Features - Active Crossover Stereo 3way-Mono 4way - 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. - 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 2ยกยฏs low output phase invert LED to indicate that this output is not operational in the LF sum mode.
