The CX168 8-Channel Low-Z Power Amplifier from QSC is a lightweight, rackmount, 8-channel power amplifier with a custom security cover, built primarily for use in fixed installation sound systems. The 90W per channel unit offers a solid complement of controls and indicators, featuring detented rotary gain control knobs, LF filter switches, clip LEDs, and an HD-15 Dataport, which enables computer-networked remote amplifier management and signal processing, using Q-SYS software. The CX168 is equipped with a variable speed fan cooling system with rear to front airflow and energy-efficient Powerwave technology for the switching power supply. The Powerwave design sends current to the amp's power circuitry via a very low impedance circuit, charging the supply rails a staggering 230,000 times a second. The result is a consistently clean signal and predictable power distribution, with lowered thermal buildup and improved signal reproduction.
Features- Lightweight 21 lb, 8-channel power amplifier with 90W per channel at 8 Ohms
- Integrated security cover for set-and-forget tamper-proof installation
- Proprietary PowerWave switch-mode power supply technology for efficient performance and compact size
- Innovative Active Inrush Limiting design eliminates AC inrush current, eliminates cost of and need for expensive power sequencers
- Variable-speed fan cooling with rear-to-front airflow and front-panel grill
- HD-15 DataPort connectors for Q-SYS networked control and monitoring
- Bridgeable channel pairs for flexible routing, power distribution
- Individual Channel DIP switch control for clip limiters, high-pass filters, bridge-mono and parallel operation
- Selectable high-pass filters protect speakers, prevent speaker transformer saturation with minimal effect on program material
- Comprehensive protection circuitry includes DC, infrasonic, thermal-overload, and short-circuit protection
- Dedicated front-panel indicators include Signal, Clip/Protect, unique Bridge-Mono and Parallel LEDs
- Individual front panel 1 dB detented rotary gain controls for simplified, more precise settings
- Detachable Euroblock input connectors
- Unified barrier strip output connector
