The PA 2100 DSC is a sophisticated class D multichannel amplifier with an integrated 8 × 8 DSP matrix. It delivers outstanding sound quality with low power consumption and low levels of heat generation. The amplifier comprises 8 symmetrical inputs and 8 outputs. OUT 1 – 2 are speaker outputs each with 100 watts power. OUT 3 – 8 are symmetrical LINE OUTs. Single or multiple amplifiers in the PA-DSC series can be connected via Ethernet or USB, programmed using the DSC Control software and a PC, and operated using 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, and compressors and limiters for each input and output. We can also preconfigure project-specific settings on request.

The highly efficient, class-D power amplifier modules in the PA DSC series are equipped with complex limiters that guarantee stable, distortion-free operation even with low load impedances. 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 individually independently or in groups using our WP-V and RP-V volume controllers or the DV module and UP/Down contacts.

Any fault in the power amplifier channels is signaled via the isolated fault contact. Inputs 1 – 4 are set up as XLR terminals. The remaining inputs and outputs are equipped with pluggable screw-type terminals.
