Our PA series of multi-channel power amplifiers comprises sophisticated class D amplifiers designed for use in AV systems, multi-room systems and multi-channel public address systems. They deliver outstanding sound quality with low levels of heat build-up and are equipped with almost completely silent, temperature-controlled fans. Integrated peak limiters prevent distortion with input levels of up to 26 dBu. To enable remote control, the amplifiers are equipped with an ON/OFF contact and VCA inputs with separate channels 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. The front features LEDs for signal, limit and protect as well as gain controllers for each channel, and bridge LEDs for each channel pair. Protect mode is triggered for any of the power amplifier channels via the isolated fault contact. The device is connected to the mains via a cold device cable. The inputs are equipped with IN and THRU XLR terminals. Two channels can be operated respectively in stereo, parallel or in a bridge. The speaker outputs are equipped with pluggable, screw-type terminals for cable cross sections up to 2 × 4 mm².
