Coaxial digital input with 24 Bit / 96 kHz
for VIOLECTRIC headphone amps
With this circuit it is possible to provide a coaxial digital input for Violectric headphone amps.
The coaxial digital input can be used to connect a digital device with a coaxial digital
output (often called "S/P-DIF") like CD/DVD-Players or computers.
PCM coded 2-channel digital data with sampling rates from 28 ... 108 kHz are supported.
The electrical characteristics meets the S/P-DIF standard while the incoming data may be "professional" or "consumer" coded.
The built-in digital receiver forwards the data to a separate D/A converter offering 110 dB dynamic range and –100 dB THD+N.
The converted digital data has priority over all other analog inputs and will mute these when valid data is received.
In case of ordering a headphone amp and the COAX input at the same time,
the headphone amp will be delivered with the COAX 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.
