OPTO 24/192 for HPA

Optical digital input with 24 Bit / 192 kHz
for VIOLECTRIC headphone amps

With this circuit it is possible to provide an optical digital input for Violectric headphone amps.

The optical digital input can be used to connect a digital device with an optical digital
output (often called "Tos-Link") like CD/DVD-Players or computers.
PCM coded 2-channel digital data with sampling rates from 28 ... 210 kHz are supported
.
The characteristics meets the Tos-Link standard EIAJ RC-5720 while the incoming data may be "professional" or "consumer" coded. 

The USB receiver forwards the data to a separate D/A converter offering 115 dB dynamic range and –103 dB THD+N with outstanding sound because of the carfully designed analog output stage.

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 OPTO input at the same time,
the headphone amp will be delivered with the OPTO 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.
