DAC8 PRO

The nicest 8-channel D/A converter

Analog performance redefined

Analog topology by Okto Research employing high-speed fully-differential operational amplifiers results in exceptionally low harmonic and intermodulation distortion. Our approach to power supply design renders extremely clean analog output, free of undesirable RFI and with undetectable level of mains harmonics.

Measurement below shows the analog output of the DAC8 PRO with volume set to -2dBFS receiving a 1kHz signal from a budget USB-SPDIF adapter. It was taken using a Rohde & Schwarz UPV audio analyzer.
