Behringer CX3400 Pro Super-X Crossover

The Behringer CX3400 Pro Super-X Crossover is equipped with state-of-the-art Linkwitz-Riley filters, and features stereo 2-way/3-way and mono 4-way crossover functionality. The CX3400 utilises ervo-balanced and golt-plated XLR connectors for each of its inputs and outputs, with switchable 25Hz low-cut filters and individual limiters providing exceptional loudspeaker protection. The unit's ultra-high precision potentiometers ensure superior accuracy and repeatability, whilst illuminated switches allow for simple operation even in the darkest of environments. Individual gain controls, mute switches, and phase-reverse switches enable intuitive and efficient operation, whilst a shielded toroidal mains transformer ensures minimal noise interference. With a wide array of professional features, the high-performance CX3400 creates incredibly accurate audio frequency separation.
