Designed for a wide range of business, music, and installed sound applications, the DMA-504 Digital Power Amplifier from RCF is a four-channel, 500W per channel class-D digital matrix power amp designed with a flexible, scalable multiroom architecture. The DMA-504 couldn't be easier to use or install and with loads of optional accessories and expansion options, it will also appeal to advanced users seeking a sophisticated heart for complex audio setups.
Unbalanced RCA inputs and outputs are offered for simple analog audio I/O while Euroblock push-terminals are employed for balanced audio input and power distribution to up to four destinations. A user-friendly and accurate interface makes control simple, including a large control knob and bright graphical LCD display for control of DSP functions, linear phase filters, compressors, 3-band EQ, tone control, algorithmic bass enhancement, and routing options, including specific presets for RCF speakers. You can even view device information and a real-time VU-meter.

- RC 401: 1 volume and 2 buttons equipped wall mount control panel. Connection is easy with a Cat 5 shielded cable and the controller allows for adjusting the output volume, muting it, or selecting the desired input program.
- RDNet BOARD DMA: an expansion board for DMA amplifier units that instantly enables your devices to access an RDNet network. In combination with RDNet compatible devices and software, it allows control and real-time monitoring of all amplifier's parameters.
- BM 404: a desktop paging console that allows making selective calls to 4 zones. Specifically designed as a complement for business music systems, such as DMA amplifiers, the console is made of a shock-resistant polymeric body, fitted with an electret microphone on a 230mm gooseneck and a polyurethane foam windscreen. Connect up to 4 consoles on a single chain (interlocked) to each amplifier with a Cat 5 cable (included). Dedicated buttons with LEDs allow for microphone activation and zone selection. Chime tone is selectable with a single on/off switch. The RCF BM-404 is ready to use out of the box and does not require any configuration.
- RM-KIT DMA: this accessory allows for mounting DMA amplifiers individually or two amps side-by-side in a standard 19" rack cabinet. In case of a single amplifier, the empty half-rack unit can be closed with a blind panel (included). It also includes a set of brackets for wall-mount installation.
- BT BOARD DMA: an additional board that allows to connect a DMA amplifier to a mobile device using Bluetooth 5.0 technology. This makes possible to send audio from the mobile device to the amplifier, and at the same time, control levels and equalization of inputs and outputs.
- AR 1050: a 1 RU accessory for installation in RCF CR2600 series racks.
