Introduction
Built for system integrators, the CXD series amplifiers provide multi-channel amplification with built-in DSP and enough power to drive wide varieties
of speaker systems with optimal energy efficiency. The CXD Series consists of three light-weight, 2RU, four-channel amplifiers with on-board DSP and
flexible channel combining as well as 70V and 100V direct drive. These amplifiers not only provide the power and processing to make your system
perform better, they offer outstanding efficiency ensuring that energy costs are kept to a minimum over the life of the installation.
CXD amplifiers feature Flexible Amplifier Summing Technology (FAST). Depending on the model, 1600, 2500, or 5000 Watts of total power can be
distributed across one to four outputs. In addition, the CXD4.3 and CXD4.5, can drive 70V or 100V speaker lines directly from any one or all of the four
outputs. This flexibility allows CXD Series amplifiers to drive (for example) two full-range, surface-mounted loudspeakers along with a subwoofer and
one 100 V distributed loudspeaker line; or a high-power subwoofer and a bi-amplified full-range loudspeaker; three 70V distributed loudspeaker lines
and a subwoofer; or a single very high-power channel to drive monster subwoofers.
The CXD Series amplifiers use QSC’s third-generation class-D power amp design in combination with a custom power stage utilizing a new output
device. In addition, CXD amplifiers employ the proven PowerLight power supply in conjunction with Power Factor Correction (PFC) which aligns the
current waveform with the AC mains voltage waveform. PFC enables the CXD Series amplifiers to draw current from the wall in a more efficient and
controlled manner resulting in very high power from a single standard AC breaker. Additionally, the CXD Series amplifiers offer multi-stage sleep
modes saving energy when possible without sacrificing performance. The result is an exceptionally powerful and flexible platform that offers low
weight and efficiency.
With four channels of amplification plus signal processing in just 2RUs, the CXD series replaces equipment taking up as much as three times
the rack-space.
A single CXD Series amplifier is a capable and sophisticated loudspeaker processor. Integration of processing and amplification means that the DSP
knows exactly what the amplifier is doing so dynamics processing can be far more accurate and effective. This approach employs both RMS and Peak
Limiters that allow the amplifier and loudspeaker to produce more output without being pushed to distortion or destruction.
The on-board DSP offers four channels of cross-over filters, parametric EQ/Low-shelf/High-shelf, alignment delay and dynamics processing —
everything needed to optimize a loudspeaker system. Additionally when using QSC loudspeakers, CXD amplifiers provide Intrinsic Correction™, a
combination of filtering, limiting and loudspeaker knowhow that was first developed for QSC's WideLine line-array loudspeakers. Intrinsic Correction
compensates for the non-linearity in array and horn design resulting in exceptional performance.
The CXD also includes manufacturers' recommended tunings for the most popular passive loudspeakers. A system setup wizard helps you select the
right preset, or select one of the 20 configuration templates and create tunings that you can save in the user preset library.
With a dedicated front panel user interface, complete with LED meters and indicators, a 400 x 240 TFT color display, a rotary encoder and navigation
buttons, the CXD amplifiers provide an intuitive means to control the system.
Unpacking
There are no special unpacking instructions. You may want to keep the shipping material for the unlikely event that the amplifier should need
returning for service.
