4000W Amplifier using FAST channel combining technology. 4 Channel, 900 watts/ch at 8Ω, 1400 watts/ch at 4Ω, 1200 watts/ch at 2Ω, 500 watts/ch direct drive 100V, 625 watts/ch direct drive 70V
The QSC CXD4.3 Processing Amplifier from the 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.
The CXD4.3 Processing Amplifier features FAST (Flexible Amplifier Summing Technology) that actively distributes the total amplifier power in various configurations across 1, 2, 3, or all 4 outputs. Moreover, this power can also be used to drive 70 or 100V speaker lines directly from any 1 or all of the 4 outputs. This flexibility allows this amplifier to drive (for example) 2 full-range surface mounted speakers along with a subwoofer and a 100V distributed speaker line; or a high-power subwoofer and a bi-amplified full-range loudspeaker; three 70V distributed speaker lines and a low impedance surface mount speaker line; or a single high-power channel driving monster subwoofers.
