The CX34 is a 2 or 3-way stereo or 4-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]50k ohms[br]Input impedance : unbalanced[tab]25k ohms[br]Output impedance[tab]200 ohms[br]Crossover ranges[tab]45-960Hz (switchable 10x) or 450Hz-9.6kHz[br]Filter slope[tab]24dB/octave[br]Frequency response[tab]20Hz - 20KHz, +0/-0.5dB[br]Signal to noise ratio[tab]>90dB[br]THD[tab]<0.004% @ +4dBu, 1kHz[br]Dimensions[tab]482 x 44 x 170mm[br]Weight[tab]2.5kg
