Amplifier- QSC CX168

Updated August 6, 2026

Amplifier- QSC CX168 Product Overview 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 . 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. Features 90W per channel @ 8 , 130W @ 4 Channel pairs bridgeable for maximum flexibility PowerWave technology delivers tighter bass and cleaner highs Four HD-15 DataPort connectors (one per channel pair) for Q-SYS control/monitoring Specifications Power Ratings: 8 , 0.05% THD: 90W 4 , 0.1% THD: 130W Midband Rating, 8 , 0.1% THD 1 kHz: 100W all channels, 120W single channel Midband Rating, 4 , 0.1% THD 1 kHz: 140W all channels, 180W single channel 16 0.1% THD 20 Hz - 20 kHz: 180W 8 0.1% THD 20 Hz - 20 kHz: 260W Input Impedance: 6 k unbalanced, 12 k balanced Input Connectors: 3-pin Euro-style detachable terminal blocks (one per channel) Data Port Connector: HD-15 Connector (Ch 1+2, 3+4, 5+6, 7+8) Output Connector: Two 8-pin Euro-style detachable terminal blocks Front Controls: AC switch, Ch 1, 2, 3, 4, 5, 6, 7 and 8 gain knobs Rear Controls: DIP switches for Ch. 1 - Ch. 8, clip limiter on/off, LF filter on/off, LF filter freq select 33 or 70 Hz, inputs parallel or stereo; bridge mode Amplifier Protection: Full short circuit, open circuit, thermal, ultrasonic and RF protection; Stable into reactive or mismatched loads Load Protection: On/off muting; individual channel DC fault blocking Dimensions (W x H x D): 19" x 3.5" x 14" (2 U) Weight: 21 lbs. net, 27 lbs. shipping
