The two-way stereo/three-way mono Crest Performance CPC-1223 crossover features a true fourth order Linkwitz/Riley crossover filter with improved selectivity to 24 dB/octave and an extended crossover frequency range from 60Hz to 6 kHz.
Both of the CPC-1223’s channels feature ±20 dB gain control and switchable 24 dB/octave low cut filter at 40 HZ roll-off frequency. Each frequency band within the two channels has a 20 dB level control, polarity and mute switches, a green signal-presence LED (-20 dBu threshold) and a red Clip/Mute LED.
In addition, each of the two high frequency sections features an adjustable CD horn EQ boost control from 0 to +12 dB. Plus there is an independent sub-woofer output on the rear panel.
