Designed for permanently installed sound systems where rackspace is at a premium, QSC's CX168 power amplifier provides unprecedented levels of channel density for multi-channel amplifiers. The CX168 delivers 90W per channel @ 8 Ω. 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, and incorporate QSC's legendary PowerWave technology, creating tighter bass and clean, transparent highs. PowerWave also cuts waste heat, boosts reliability, and eliminates unwanted noise and hum. This revolutionary switching power supply technology that provides ample current to the audio power circuitry by charging the supply rails over 200,000 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.
