The 4-channel CX254 amplifier gives you four channels in only two rack spaces-without compromising on power. This low impedance amp is equipped with QSC's 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 CX254 is the perfect solution to any permanently installed sound system.
The CX254 now incorporates QSC's exclusive PowerLight technology and has a low impedance at:
-
170 watts/ch at 8 ohms
-
250 watts/ch at 4 ohms
-
450 watts/ch at 2 ohms
With PowerLight technology, the CX254 amplifier takes 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.
