RCF Audio’s DMA 504 is a class-D matrix amplifier for desktop or rack installation, offering four 500W channels with a powerful DSP platform.
The DMA 504 is housed in a 2U-rackmount case suited to a wide range of applications, from retail stores to bars and restaurants, meeting rooms, education and public facilities where background and foreground music is required.
The unit’s inputs and outputs can be managed in terms of routing and equalisation with a comprehensive set of processing functions including PEQ, FIR filters, bass enhancement, limiters, compressors, and environmental equalisation. Presets for RCF speakers are available on each channel for simple optimisation of acoustic performance and reliability.
The DMA 504 sports two stereo line inputs on RCA connectors and a single mic/line balanced input on removable screw terminals. A mono analogue line output is also available with a low-pass filter for connection to an active subwoofer. A dedicated paging input on RJ 45 connector allows the connection of up to four BM 404paging consoles, interlocked on a single chain, and a RC 401 wallmount remote control can be connected to each output channel to select the desired input and adjust the output level.
The DMA 504 can distribute all four of its audio channels to other units through an analogue audio bus, combining a flexible and scalable multi-room architecture with an easy connection and installation. User-friendly configuration is available through the front panel controls (with OLED display), or via RDNet management software.
