The QSC CX204V is a 4-channel CX power amplifier, CX Series is the perfect solution to any permanently installed sound system.

The QSC CX204V is a 4-channel CX amplifiers give you four channels in only two rack spaces-without compromising on power. Choose from three models - a direct 70 volt model and two low impedance versions, each equipped with our exclusive PowerLight switching power supply technology to virtually eliminate noise and hum. 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 PowerLight technology, CX amplifiers take your sound to a whole new level. Not only does it give you tighter bass and clean transparent highs, PowerLight also cuts waste heat, boosts reliability and gets rid of unwanted noise and hum. PowerLight 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.
