State-of-the-art technology in established design – the DSP.3 has been continually refined and presents itself as our best digital 8-cahnnel signal processor we have ever built.

Searching for the perfect sound pushes our engineers on and on. The 64-bit audio DSP and throughout sophisticated signal processing with 96kHz sampling rate and native 32-bit resolution as well as the new separated ADC: AK5556 and DAC: AK4458 from Asahi Kasei Microdevices (AKM) provide outstanding sound quality.
