ProductsPower AmplifiersCX Series

The CX Series amplifiers are designed to meet the specialized needs of sound contractors. Featuring PowerLight™ switch mode power supply technology and features like gain control security panels and 70 volt direct models. All models feature DataPorts for integration with Q-Sys or QSControl.net systems.

The CX 2-Channel Series is designed to meet the specialized needs of sound contractors. Eight models have been designed from the ground up, combining QSC's exclusive PowerLight® technology with specific features to meet the requirements of fixed installations. With high output power, versatile loading options, high thermal capacity and proven reliability, the CX Series is the ideal solution to any permanently installed sound system.

The model line incorporates QSC's exclusive PowerLight technology. Three models, the CX302V, CX602V and CX1202V, provide direct 70 volt capability ranging from 250 watts to 1000 watts per channel for distributed audio systems. The CX302, CX502, CX702, CX902 and CX1102 offer low impedance capability and range in power from 325 watts to 1100 watts per channel at 4 ohms (20 Hz -20 kHz, 0.05% THD). The versatile CX902 and CX1102 have the ability to drive both 70 volt and low impedance loads for maximum flexibility. 

The CX amplifiers are equipped with many contractor specific features including 1 dB detented gain controls for easily repeatable settings and a custom security cover for tamper-proof installations. Active inrush limiting eliminates AC inrush current, cutting the need for power sequencers. 

CX amplifiers also include an HD15 Data Port connector to interface with Q-Sys and QSControl networked audio systems, for remote amplifier monitoring and control. 

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. 

Designed for permanently installed sound systems where rackspace is at a premium, QSC's CX108V and CX168 provide unprecedented levels of channel density for multi-channel amplifiers. The CX108V and CX168 provide 100 watts per channel at 70 volts and 90 watts per channel at 8 ohms 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.
