The QSC CXD4.5 Processing Amplifier from CXD Series is designed specifically for the needs of integrators. It provides efficient, robust, and high-fidelity power to drive multiple channels and configurations of loudspeakers. It simultaneously deploys sophisticated digital processing with optimal energy and rack space efficiency. This 4-channel amplifier with onboard DSP has the capability to configure and combine channels in various ways to drive a wide range of loudspeaker systems including 70V and 100V without the use of transformers. This amplifier not only provides the power and processing to make your system perform better, it also offers efficiency ensuring that energy consumption will be kept to a minimum over the life of the installation.
Flexible Amplifier Summing Technologyâ¢ (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.
