The PA 2100 S-DSC is a compact, remote controllable 2-channel digital amplifier with integrated DSP. With minimal dimensions the PA 2100 S-DSC has a output power of 2 × 100 watts at 4 ohms, 2 × 60 watts at 8 ohms or 2 × 100 watts at 2 ohms. In bridge mode, it ­delivers output power of 1 × 200 watts at 4 or 8 ohms, guaranteeing excellent sound quality at all times. Single or multiple amplifiers in the PA S-DSC series can be connected via Ethernet, programmed using the DSC Control software and a PC, and operated using a media control system.

In addition to the 2×2 mixer matrix, the DSP also offers ten fully parametric filters, a delay of up to 10 ms, and compressors and limiters for each input and output. Up to 100 presets can be stored permanently. We can also preconfigure project-specific settings on request. The integrated limiters guarantee stable, distortion-free operation even with low load impedances.

The amplifiers are equipped with an automatic switch-on function, an ON/Stand-by contact and VCA inputs for external volume control. The amplifiers can be controlled individually or in groups using the WP-V and RP-V volume controllers or the DV module and UP/DOWN contacts. Up to 4 compact amplifiers can be mounted in 19” racks in a single height unit (in PA-T 1U).
