Built for system integrators, the CXD4.2 amplifiers provide multi-channel amplifi cation with built-in DSP and enough power to drive wide varieties of speaker systems with optimal energy effi ciency. The CXD4.2 consists of three light-weight, 2RU, four-channel amplifi ers with on-board DSP and fl exible channel combining as well as 70V and 100V direct drive. These amplifi ers not only provide the power and processing to make your system perform better, they offer outstanding effi ciency ensuring that energy costs are kept to a minimum over the life of the installation.
The on-board DSP offers four channels of cross-over fi lters, 5-band parametric EQ/Low-shelf/High-shelf, alignment delay and dynamics processing — everything needed to optimize a loudspeaker system. Additionally when using QSC loudspeakers, CXD amplifi ers provide Intrinsic Correction, a combination of fi ltering, limiting and loudspeaker knowhow that was fi rst developed for QSC's WideLine line-array loudspeakers. Intrinsic Correction compensates for the non-linearity in horn and driver design resulting in exceptional performance. The CXD also includes manufacturers' recommended tunings for a number of the most popular passive loudspeakers. A system setup wizard helps you select the right preset, or select one of the 20 confi guration templates and create tunings that you can save in the user preset library. Whether using the dedicated front panel user interface featuring a 400 x 240 display, rotary encoder and navigation buttons, or the Amplifi er Navigator software on a PC or Mac, the CXD amplifi ers are an ideal amplifi er/processing platform for installations.
Features
- Flexible Amplifier Summing Technology™ (FAST) drives most any loudspeaker system or configuration by distributing total amplifier power across one, two, three or all four channels.
- Capable of providing up to 5,000 watts continuous and 8,000 watts peak with 70V or 100V direct drive on each output of the CXD4.3 and CXD4.5, and on bridged output pairs of the CXD4.2.
- Full function onboard loudspeaker processing DSP with crossover and parametric EQ Filters, limiting and alignment delay eliminate the need for outboard loudspeaker processors.
