Dare we call the Weiss DAC204 a Swiss army knife? It is certainly the most versatile digital-to-analogue converter in Weiss Engineering’s product offering.
Use the DAC204 for easy switching between multiple units with digital outputs — including a computer or mobile with USB out — and enjoy the pristine and low-jitter conversion to analogue audio from the unit’s outputs. The DAC204 can also convert DSD audio to PCM and offers a digital output in the AES/EBU format.

Measurements:
*The measurements below have been taken at the following conditions (unless noted otherwise): 1 kHz measurement frequency, maximum selectable output level, 192kHz sampling frequency (Fs), 22kHz measurement bandwidth, unweighted, 0 dBr equals the output level at 0 dBFS input.
Frequency Response:
Fs = 44.1 kHz, 0Hz-20kHz: within +- 0.25dB
Fs = 88.2 kHz, 0Hz-20kHz: within +- 0.25dB
Fs = 88.2 kHz, 0Hz-40kHz: within +- 0.8dB
Fs = 176.4 kHz, 0Hz-20kHz: within +- 0.25dB
Fs = 176.4 kHz, 0Hz-40kHz: within +- 0.8dB
Fs = 176.4 kHz, 0Hz-80kHz: within +- 2.5dB
Total Harmonic Distortion plus Noise (THD+N):
−116 dBr (0.00016 %) at −3 dBFS input level
−125 dBr (0.000056 %) at −40 dBFS input level
−125 dBr (0.000056 %) at −70 dBFS input level
Linearity:
At 0 dBFS to −120 dBFS input level: less than ±0.4 dB deviation from ideal
Spurious components (including harmonics):
At 0 dBFS input level, maximum output level, 1 kHz, all components at less than −120 dBr
At 0 dBFS input level, maximum output level, 4 kHz, all components at less than −115 dBr
