Featuring powerful onboard speaker processors as standard, PC-D / DI Series amplifiers offer processing such as 16-band PEQ, delay, peak limiting, and RMS limiting, as well as FIR filter** that achieve linear phase, allowing users to tune speakers perfectly with precision and ease. Dante outputs can be used to transmit further parameter adjustments of Room EQ to other amps, allowing EQ for multiple amp channels to be adjusted centrally. The speaker preset library is well-stocked with optimized presets for the Yamaha CZR Series and others, making it effortless to achieve the perfect speaker tuning for your system.
