Page 4: Digital Inputs
SRC is impressive, with artifacts and distortion products below -140 dB. The DA8 has four AES/SPDIF digital inputs (eight audio channels) on the standard 25 pin D-sub connector at the back panel. The connector follows the YAMAHA DB-25 USB input industrial pin-out standard. -
Page 5: Analog Outputs
The DA8 has eight analog audio outputs on the standard When the incoming clock signal is lost or discontinued, 25 pin D-sub connector at the back panel. The connector the master clock oscillator gently glides back to its follows the TASCAM DB-25 industrial pin-out standard. -

Page 12: Technical Section
DA8 D/A Converter Technical section Distortion characteristics There has always been focus on distortion, when it comes to judging audio equipment. It can be argued, that any distortion product (2nd, 3rd harmonic etc) below -60 dB is inaudible, simply because the distortion tones are a consequence of the incoming tone, and thus are always masked by it. -
Page 13: Fft Distortion Analysis
DA8 D/A Converter Distortion in depth analysis. FFT (Fast Fourier Transform) A more detailed picture of the distortion characteristics can be seen using FFT analysis, which allows the magnitude of the individual distortion components to be quantified. In this FFT analysis only the distortion analysis at 48 kHz sample rate is included. -
Page 14: Crosstalk
The true balanced nature of the DA8 really pays off. The crosstalk is below -110 dB in the main part of the spectrum. Only above 10 kHz is a slight increase seen, reaching approx. -105 dB at 20 kHz Note: This is a linear and unweighted measurement. -
Page 15: Hum And Noise
DA8 D/A Converter Hum and noise Using an analog power supply with an oversized toroidal transformer and linear regulators could be cause for concern. However, not to worry. The carefully designed power circuits creates an electromagnetic quiet environment, free from the usual radiation pollution from a switch-mode power supply, and the true balance nature of the analog circuits really pays off. -
Page 16: Sample Rate Converter, Classical Distortion Analysis
DA8 D/A Converter Sample Rate Converters The DA8 has four hardware Sample Rate Converters, one on each AES input. Their quality is truly exceptional and the sonic performance is outstanding, Absolutely the best that today’s industry can offer. Classical distortion analysis of the Sample Rate Converters Input is 1 kHz @ -0.2 dBFS. -
Page 17: Sample Rate Converter, Fft Analysis
DA8 D/A Converter Distortion in depth analysis of Sample Rate Converters. FFT (Fast Fourier Transform) A more detailed picture of the distortion characteristics can be seen using FFT analysis, which allows the magnitude of the individual distortion components to be quantified. In this FFT analysis only the result of the sampling rate conversion from 44.1 kHz to 48 kHz is included.
