CD to DAC to DAT to DAC?

So I receive my Panasonic SV-3800 DAT deck yesterday...

I connect my turntable to the analog input (obviously) and connect my CD player to the digital input (TOSLINK).

I then take the coax out on the DAT deck to my DAC (and then out to the amp over RCA).

For some reason the DAT deck acts like the CD player isn't there. Do I need to run it into the DAC, then out via coax back to the DAT, and then back out to the DAC (and then into the amp)?

This doesn't seem right to me, but I'm just a bit baffled - I mean, does the signal from the CD player need to be processed prior to hitting the DAT?

Thanks,
Mark

Like I said earlier DAT operates at 48kHz sampling rate and CD at 44.1kHz. Unless the DAT is specifically designed to accept both 48kHz and 44.1kHz in the toslink input it will not accept the digital output from a CD player since it has a different sampling rate. If it can accept both frequencies the selection might be automatic or manual.

What are you trying to achieve ? Do you want to sample the turntable and put it through the DAC ? Is the turntable directly connected to the DAT, or do you mean the output of the phono preamp ? Why route the CD player through the DAT ?

Does the DAT digital input auto detect the sample rate ? CD is 44.1khz and DAT is 48khz, so sample conversion would have to occur somewhere, and if not in the DAT then this could be the problem.

Also why would the DAT player output the data stream from its digital input unless you were recording that input and monitoring (like an analog tape deck .... it doesn't automatically route the input to the output unless you're recording).
