CX168 8-CH Low-Z Power Amplifier. 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. Providing 140 W/CH into 4 ohms and 260 W/CH Bridged along with the right connector set for ease of wiring, the CX168 is ideal for installation applications. 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 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. QSC's PowerLight technology takes your audio to an entirely new level.
