DMA 162 Architectural and Engineering Specifications

DESCRIPTION
The product shall be a two-channel class-D matrix amplifier, equipped with a powerful DSP platform, allowing managing inputs and outputs in terms of routing and equalization; moreover, dedicated presets for speakers have been implemented to optimize its acoustic performance.
Output power: either 2 channels x 160 W RMS @ 4 ohm (each) or a single 320 W Hi-Z line.
It shall be suitable for either desktop or rack installation.
It shall have 2 stereo LINE audio inputs on RCA connectors, 1 MIC+LINE balanced audio input on removable screw terminals and a LINE audio output with a switchable low-pass filter useful for the connection to an active subwoofer. A dedicated input having RJ 45 connector allows the connection of up to four dedicated paging microphones (interlocked one another on a single chain).
A wall-mount remote control can be linked to each output channel in order to adjust its respective volume level and select the desired audio input.
Up to 4 audio channels can be sent to additional amplifiers (through a BUS with a single CAT5 cable), combining a flexible and scalable multi-room architecture with an easy connection and installation.
Its configuration shall be user friendly and carried out through either its front panel controls (with OLED display) or RDNet® (when dedicated optional board is installed).
The matrix amplifier can be installed into a 19” rack cabinet through an optional accessory (required for every pair, as each needs half a rack unit).
