* More Information Details: Expanded system flexibility begins here with the PCX Mono and Multi channel amplifiers. Whether you need a mono, four channel or five channel amp, PCX amplifiers give you limitless system configuration potential. At the heart of all of the PCX amplifiers, is the TC-X crossover. The TC-X crossover allows complete control of the frequencies from 30-4KHz, HP/LP/Full. On the multi-channel amplifiers, you have the front channel crossover acting as a 2-way, tracking crossover. What this means during installation is, by sending the crossover front channel signal to the rear channel, you now have the ability to Bandpass the rear channel. Every limitation has been eliminated from the PCX Line of amplifiers... What else would you expect from PrecisionPower.
