Product Description

Project DAC Box S USB


The DAC Box S USB is a high-quality Digital-Analogue Converter with three switchable inputs, allowing for multiple digital musical sources to be converted in a more convenient and better sounding way. By over-sampling the input signal, this small device produces a thorough and fluid sound performance.

The 'S' version of the DAC Box USB uses the same technology as its predecessor and has the same footprint. The only differences are in the thicker, more stylish front-plate, and the smaller power supply that helps the unit comply with new 1Watt Standby regulations outlined by the European Court.

Key Features:

Audiophile 24bit/96kHz D/A-conversion

Precision D/A chip from Texas Instruments

8 times oversampling

3 Inputs (RCA, Toslink, USB)

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

A: DAC Box 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 the USB protocol used. So if playback of 24bit audio files is needed, digital coax or Toslink inputs should be used!

Q: Why is there sometimes an audible noise noise and/or interruptions in the playback of audio files via the USB input of DAC Box USB?

A: DAC Box 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 could be suffering from capacity overload. Best remedy in this case is to close all applications on the computer, which are not currently being used.

Q: Why does no audio output seem to come from USB source the when USB cable is connected first and then the power adaptor is plugged into mains?

A: DAC Box S USB should be connected to the mains first 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.
