INTRODUCTION
Congratulations on your purchase of the CX168 power
amplifier. To help you obtain the best results from your
purchase, we encourage you to carefully review this manual.
With information including connections, configuration and
operation, it offers many useful guidelines.
The CX168 provides a high level of channel density in a small,
lightweight form factor ideal for multi-zone audio systems.
Representing the culmination of QSC’s extensive experience
in power amplifier development, the CX168 is a highly
versatile, reliable, and user-friendly tool that will likely remain
a central component of your system for years to come.
Like the entire CX Series, the CX168 is equipped with QSC’s
exclusive PowerWave
TM
switching power supply technology
to virtually eliminate noise and hum while reducing the unit’s
overall weight. Comprehensive protection circuitry includes
DC, infrasonic, thermal overload and short circuit protection.
The CX168 includes 4 HD15 DataPorts (one per channel pair)
for remote management or DSP. These ports allow each
channel pair to be governed by QSControl, QSC’s audio
networking system—enabling the system operator to control
amplifier gain levels, check the unit’s clipping and thermal
status, plus monitor numerous additional system parameters.
Alternatively, these DataPorts facilitate connection of signal
processing equipment, such as QSC’s DSP-3, which offers two
channels of independent digital signal processing - including
crossover filters, shelf filters, signal delay, compression, peak
limiting, and parametric filters.
As individual channel pairs may be bridged, the CX168 is
configurable as a 4-, 5-, 6-, 7-, or 8-channel unit. Further, the
CX168 features detachable Phoenix-style input and output
connectors—enabling the audio system to be wired with
greater ease. Other features include 1-dB recessed and
detented gain controls and a security cover for tamper-proof
installations.
The CX168 is easy to use. All operating mode switches are
grouped together on the rear panel, with one switchblock per
channel pair. These switches enable clip limiter on/off, LF
filter on/off, LF filter select and operation modes. The
amplifier’s front panel includes corresponding LEDs to indicate
Bridged or Parallel modes in addition to Signal and Clip
status.
Your CX168 power amplifier was designed to provide many
years of trouble-free, great-sounding operation. We hope you
enjoy your new CX168.
