FAQ - Hints for using DAC Box S USB  

Q: Does the device support Windows 10?  

A: The device is fully compatible with Windows 10. It may be necessary to reinstall latest drivers after updating from Windows 7/8/8.1 to Windows 10.  


Q: Does a driver exist for the DAC Box S USB?  

A: You do not need a driver for Windows-, Mac OSX- or Linux-Systems.  

The driver is already integrated in the operating system.  


Q: Is it possible to hear 24bit audio-files via USB input of DAC Box S USB?  

A: DAC Box S USB is equipped with a 24bit/96kHz DAC processor, that makes it possible to convert 24bit files into analogue, but only when using digital coax (RCA) and optical (Toslink) inputs. USB input only is able to deal with 16bit files, because of technical restrictions in USB protocol. So if playback of 24bit audio files is needed, digital coax or Toslink inputs should be used!  


Q: Why sometimes there is noise and / or interrupts in playback of audio files via USB input of DAC Box S USB?  

A: DAC Box S USB only is able to reproduce the signal which comes in. If USB input is used and noise or interrupts can be heard, the main processor suffers from capacity overload. Best remedy in this case is to close all applications on the computer, which are not used at this time.  


Q: Why no audio signal from an USB source is available on RCA-out of DAC Box S USB, when USB cable is connected first and then the power adaptor is plugged into mains?  

A: DAC Box S USB should be connected first to mains and a few seconds later the USB cable can be connected to a PC. Doing the opposite way, synchronisation process is eventually faulty and no sound is available via audio outputs.  


Q: DAC Box S USB will not be recognized by Mac OSX and is not available under Audio. What can I do?  

A: Turn off your Computer and press at start alt+cmd+p+r until another starting sound appears. With this command the USB bus will be reset and the USB Box will be recognized new.
