The USB input is 1.0 / 1.1 compatible and needs no proprietary driver.
Audio files aresent to the headphone amp whereas audio formats up to 24 bit with 44.1, 48 and 96 kHz are supported. Please note: NO 88.2 kHz !!

The USB circuitry directs the digital audio data to a hig class D/A converter with 110 dB dynamic range and -100 dB THD+N. The D/A converter is followed by a high quality analog output circuitry.

The USB input has priority over all other inputs and will mute these when valid data is received.
When the analog RCA connectors from the headphone amps are set to be outputs, here the converted data is also present.

In case of ordering a headphone amp and the digital input at the same time, the headphone amp will be delivered with the digital option installed in place.

Delivered afterwards, retrofitting is easily done and consists of pluging and screwing.

The installation manual can be mailed in advance on request.
