hi steve, just a few queries about the latest info on the pace car.
hadnt realised there was a possibility of using an external clock. can this come in via wordclock?
Yes, but only as a master clock, not a word clock input, and it must be 11.2896 or multiples or 24.756 or multiples.
would this allow the possibility of a wider choice of clock rates if the external clock can generate them?
The Pace-Car version 3 can output master clock, bit clock or word clock for 16/44.1 or 24/96. Input is only master clock.
does the quality of the onboard clock become irrelavent if using an external one?
In the transport or networked converter, the internal clock is replaced with the Pace-Car clock. For Transports, the word clock will lock the internal master clock. The quality of the transport clock is not important.
If you are inputting a clock, the there is no need for an internal clock in the Pace-Car.
will the pace car be able to handle 48k sample rate?
No. Mainly because the converters and DAC's do not support AC3 anyway.
this is going to be important for dvd playback, i dont know of a software dvd player that will upsample to 96k. also wondered about the reason for having 44.1 sample rate limited to 16 bit?
I had not planned on provinding the frequencies required for DVD players. These are usually 27MHz master clock and there is a frequency synthesizer that creates all of the other frequencies. DVD players do not have a clock that can lock-on to a word-clock.
I could make a customized version to do 24/48 though.
