The CX23 is a 2-way stereo or 3-way mono active crossover designed to split frequencies so that low frequencies are delivered to the amp driving the sub cabinets and mid/top frequencies are delivered to the amp driving the mid/top frequency cabs. This type of system is more efficient and delivers more accurate sound quality, especially in larger PA systems.Power supply[tab]115/230Vac, 50/60Hz (IEC)[br]Input impedance : balanced[tab]40k ohms[br]Input impedance : unbalanced[tab]20k ohms[br]Output impedance[tab]220 ohms[br]Crossover ranges : stereo[tab]50Hz-5kHz;750Hz-7.5kHz[br]Crossover ranges : mono[tab]50Hz-5kHz;750Hz-7.5kHz; 2kHz-20kHz[br]Filter slope[tab]18dB/octave[br]Frequency response[tab]20Hz-25kHz +0/-1dB[br]Signal to noise ratio[tab]>90dB[br]THD[tab]0.006%[br]Dimensions[tab]482 x 44 x 170mm[br]Weight[tab]2.5Kg
