DMA 162P Architectural and Engineering Specifications DESCRIPTION The product shall be a two-channel class-D power amplifier. Output power: either 2 channels x 160 W RMS @ 4 ohm (each) or a single 320 W Hi-Z line. Up to 4 amplifiers can be linked to a single matrix amplifier unit in order to increase the system output power and implement multi-room architectures. Yet, each amplifier can be used as a stand alone amplifier as well. It shall be suitable for either desktop or rack installation. It can receive processed audio signals from a matrix amplifier on a four-channel audio BUS (CAT5 cable), or as alternative, it is possible to select the local stereo LINE input (by closing the dedicated contact). A LINE output is also available, with a switchable low-pass filter for the connection to an active subwoofer. Its configuration can be carried out though either the dip-switches on its rear panel or RDNet® (when its optional board is installed). The amplifier can be installed into a 19” rack cabinet through an optional accessory (required for every pair, as each needs half a rack unit).
