QSC CX168 overview

  • 1Description

The QSC CX168 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 HD15 Dataport, which enables computer-networked remote amplifier management and signal processing, using QSControl software.

The CX168 is equipped with a variable speed fan cooling system with rear to front airflow, and the 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

The CX168 incorporates the design, cost-effective operation, and performance features that QSC is able to implement after three decades of experience building amplifiers serving all professional sound markets.

Lightweight 21 lbs, 8-channel power amplifier with 90W per channel at 8Ω
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 speedfan cooling with rear to front airflow and front panel grill
HD15 DataPort connectors for QSControl computer software integration, remote control of installed setups
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 1dB detented rotary gain controls for simplified, more precise settings
Detachable Euroblock input connectors
