Q: Is it possible to hear 24-bit audio-files via USB input of DAC Box S USB?
A: DAC Box S USB is equipped with a 24-bit/96 kHz DAC processor, that makes it possible to convert 24bit files into analog, but only when using digital coax (RCA) and optical (Toslink) inputs. The USB input is only able to deal with 16-bit files, because of technical restrictions in USB protocol. So if playback of 24-bit audio files is needed, digital coax or Toslink inputs should be used
Q: Why is there occasional noise and / or interrupts in playback of audio files via the USB input of the DAC Box S USB?
A: DAC Box S USB only is able to reproduce the signal which comes in. If the USB input is used and noise or interrupts can be heard, the main processor suffers from capacity overload. The best remedy in this case is to close all applications on the computer which are not used at this time.
Q: Why is no audio signal from an USB source available on the RCA-out of the DAC Box S USB, when the USB cable is connected first and then the power adaptor is plugged into the AC outlet?
A: The DAC Box S USB should be connected first to your AC power source and a few seconds later the USB cable can be connected to a PC. Doing it the opposite way, synchronization process may be faulty and no sound will be available via the audio outputs.
