QSC CX108V 8 Channel 70V Power Amplifier (Discontinued)

Part # CX108V
Model # CX108V

The QSC CX108V amplifier is designed for permanent installation sound systems where rackspace is at a premium, and provides unprecedented level of channel density for a multi-channel amplifier.

Description

Details

The CX108V provides 100 watts per channel at 70 volts respectively. With both models, each pair of channels may be bridged to configure these amplifiers as 4, 5, 6 or 7 channel units. Like the entire CX Series, the 8-channel models feature DataPorts for remote amplifier management or signal processing, incorporate QSC's legendary PowerLight technology, and deliver our unmatched reputation for quality and reliability.

QSC's PowerLight technology takes your audio to an entirely new level. Delivering tighter bass and clean, transparent highs, PowerLight also cuts waste heat, boosts reliability, and eliminates 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 per second through an ultra-low noise impedance circuit. Unlike amplifiers that use conventional supplies, the audio signal is never starved prematurely and remains crisp and clean.
