Description

The PA 4800 DSC is a sophisticated, class-D multi-channel power amplifier with an integrated 8×8 DSP matrix and two sockets for different input modules. The three different models in this series are equipped with symmetrical line inputs, asymmetrical cinch inputs or an 8-channel Dante module, and can be expanded by adding a second input module. By combining two input modules, the power amplifier can be operated as a central amplifier unit with a mix of analog and digital signal sources. Ground Lift switch for each input channel pair plus dip switches for modifying input sensitivity on each channel enable the amplifier to be easily adjusted to different signal sources.

The PA 4800 DSC circuits are designed to ensure outstanding sound quality and safety levels with minimum heat build-up. The generously proportioned, high-capacity mains adapter together with our new processor-controlled class-D power amplifier modules guarantee outstanding efficiency levels and enormous power reserves. The Automatic On/Off function (switchable for each channel) automatically switches inactive amplifier channels to an energy-saving Sleep mode. The power amplifier has an output rating of 4 × 800 watts at 2 - 4 ohms or 2 × 1600 watts at 4 - 8 ohms in bridge mode, the outputs 5 - 8 are symmetrical line outs.

One or more power amplifiers in the PA DSC series can be connected via Ethernet or USB, programmed using the LB AUDIO CONTROL app on a PC, and operated via a media control system. In addition to the 8 × 8 mixer matrix, the DSP also offers ten fully parametric filters, a delay of up to two seconds, plus compressors and limiters for every input and output. We can also preconfigure project-specific settings on request.

To enable remote control, the amplifiers are equipped with an On/Off contact and VCA inputs with separate channels for external volume control. All outputs can be controlled independently or in groups using our WP-V and RP-V volume controllers or the DV module via Up/Down contacts. Any fault in the power amplifier channels is signaled via the isolated fault contact.
