QSC CX204V

The QSC CX204V 4-channel CX amplifier give has four channels in only two rack spaces - without compromising on power. With high output power, versatile loading options, high thermal capacity and unmatched reliability, the CX Series is the perfect solution to any permanently installed sound system.
With PowerWave technology, CX amplifiers take your sound to a whole new level. Not only does it give you tighter bass and clean transparent highs, PowerWave also cuts waste heat, boosts reliability and gets rid of unwanted noise and hum. PowerWave is a revolutionary switching power supply technology that provides ample current to the audio power circuitry by charging the supply rails 230,000 times a second through an ultra-low impedance circuit. So unlike amplifiers that use conventional supplies, the audio signal is never starved prematurely and remains crisp and clean.

Features:

• Compact size
• Bridgeable channels 1 + 2 and 3 + 4, for maximum flexibility
