Overview
DMA 504 is a four channels Class-D matrix amplifier 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 PEQ, FIR filters, bass enhancement, limiters, compressors and environmental equalization. Moreover, specific presets for RCF speakers have been implemented, and can be selected to optimize their acoustic performance.
