DMA 504 Architectural and Engineering Specifications

DESCRIPTION
The product shall be a four-channel class-D matrix amplifier, equipped with a powerful DSP platform, allowing managing inputs and outputs in terms of routing and equalization. It shall offer output power both four-channels x 500 W RMS @ 4 ohm (each) or two-channels 1000 W Hi-Z line. It shall be suitable for both 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.
