- Description
Details
The CXD4.2 consists of three powerful, four-channel amplifiers, each with onboard DSP and 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. These amplifiers not only provide the power and processing to make your system perform better, they offer outstanding efficiency ensuring that energy costs will be kept to a minimum over the life of the installation.
Flexible Amplifier Summing Technology (FAST)
CXD4.2 amplifier features Flexible Amplifier Summing Technology (FAST) that actively distributes the total amplifier power in various configurations across one, two, three or all four outputs. This flexibility allows CXD4.2 amplifier to drive (for example) two full-range surface mounted speakers along with a subwoofer and one 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.
Power Efficiency
CXD4.2 amplifier use QSC’s next generation class-D power amp design in combination with a custom power stage utilizing a new output device. These purpose built MOSFET devices provide high voltage operation without needing a full bridge output and offer better audio quality and thermal performance due to co-location of the semiconductors.
CXD4.2 amplifier benefit from the proven PowerLight power supply, made even better with Power Factor Correction (PFC) that aligns the current waveform with the AC mains voltage waveform. PFC enables CXD4.2 amp to draw current from the wall in a more efficient and controlled manner resulting in incredible power from a single standard AC breaker.- Features
