Description
The RCF DMA 504 is a four-channel Class-D matrix amplifier providing 4 power outputs of 500 Watts each. Equipped with a powerful DSP platform, inputs and outputs can be managed in terms of routing and equalization. The complete set of processing functions includes PEQ, FIR filters, bass enhancement, limiters, compressors, and environmental equalization. Presets for RCF speakers are available on each channel for optimal acoustic performance and reliability. It can distribute 4 audio channels to other units through an analog audio BUS, combining a flexible and scalable multi-room architecture with an easy connection and installation. Configuration is simple and user-friendly and can be carried out through either the front panel controls (with OLED display) or RDNet. Thanks to its installation flexibility, accurate design, and robustness, DMA 504 is ideal for a wide range of business music and installed sound applications.
DMA Series
Class-D amplifiers equipped with a powerful DSP platform, allowing managing inputs and outputs in terms of routing and equalization. A complete set of processing functions is available, including speaker presets, proprietary bass enhancer algorithm, FIR filters, and environmental equalization. Thanks to its extremely compact size, accurate design, and robustness, it is ideal for a wide range of applications.
Scalable architecture
To fit with any installation need, DMA amplifiers have been designed with a highly scalable architecture and each device can distribute 4 audio channels to satellite units. This allows for increasing installed power and creating a multi-room architecture. The connection can be done with just 1 CAT5e cable.
Full on-board processing
Equipped with a powerful DSP platform, DMA units integrate RCF proprietary technologies such as FiRPHASE, a FiR filtering technology, and BASS ENHANCER, a sophisticated algorithm that increases low frequencies perception without affecting the output power.
Speakers presets
Pre-loaded presets, to optimize the performance and equalization of any RCF speaker and to have the right RCF signature sound.
Easy and flexible configuration
RCF Business Music products are ready to use in few steps, even faster when connected to the RDNet networked management.
