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.
Processing Functions
The DMA-504 is packed with a host of DSP functions that provide enough flexibility for handling any environment or usage scenario. Proprietary filters and algorithms pair with standard features like EQ and compression for a comprehensive range of functions.
- FiRPHASE linear phase filters
- 80 to 200 Hz high-pass filter
- Proprietary bass-enhancement algorithm
- 3-band EQ and tone control
- Environmental equalization for adapting to different room sizes and spaces
- Specific presets for RCF speaker models
- Multiple compressors
- Real-time VU-meter and device information via graphic LCD display
Routing and I/O
With tons of Euroblock power and audio routing, along with RCA I/O, the DMA-504 has a lot of options for setting up your audio system. Whether driving a single room, single-stage setup, or powering a complicated multi-room system, this matrix power amp has you covered. Control is easy with the intuitive front-panel interface.
- Four unbalanced RCA inputs (two stereo pairs), two unbalanced RCA outputs (stereo pair)
- 3.5mm Aux input on front panel
- Three RJ45 terminals for equipment networking (satellite terminals) and paging
- USB-B for firmware updates and software configuration
- Euroblock push-terminal balanced inputs, Euroblock remote connectors
- Eight Euroblock power outputs for speakers
- Level, mute, and output routing controls via front panel
- Customizable names for inputs, outputs, and connected devices
Customizable and Expandable
The DMA-504 is compatible with a range of accessories and expansion devices for enhancing functionality. This amplifier is RDNet ready (with the appropriate connection board), and it can be made to support rack mounting, Bluetooth app control, and more. The DMA-504 is compatible with the following accessories and modules:
- 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.
