ODI768: Octal Digital Input 768kHz:

 

Digital Audio Sources

Many stereo audio sources today are digital such as CD, DVD, digital TV etc. All players of that category have analogue outputs, using them would distorte the sensitive audio signal.

S/PDIF Audio Signals 

In the meantime, however, most players have an optical or electrical digital output too. Those outputs deliver in general a standardized digital audio signal named S/PDIF (asymmetrical).

Toslink

The optical output via toslink also delivers a signal specified to S/PDIF. Both can be recorded by the behold ODI768. Within certain limits it doesn't matter at which data rate the signal arrives.


All Signals

between 32 kHz and 108 kHz are processed in the best possible way. Consequently also the known sampling rates of 44,1 kHz (CD-player), 48 kHz (DVD, DAT + TV),96 kHz (studio technology) and 192kHz (SACD) are recorded.

No Forwarding

Octal Digital Input means of course no output so no forwarding of digital audio signals from behold to other digital devices. If this feature is wanted you have to use the DIO768 module.

In Two Steps 

It may be mentioned here that all signals in the behold DIO768 are converted in two steps. At first they are converted step-less from the input initial data rate to 192 kHz sampling rate and from there fourfold to the 768 kHz already known.

Highest Possible Level

The signals then are available for further processing in the system on highest possible level. We of course can not process information not available in the digital audio signal. We can, however, reduce considerably the negative effects which unavoidable appear at low sampling rates. 

It applies also here that the number of ODI768 is arbitrary to the pre-amp APU768 as long as there is space.
