cd to dac connection ? Help pls !

squonkster · 3rd October 2010, 02:13 PM

Hi, I have bought a Kinshaw dac ....BUT i cannot see a Toslink connection which is the only digital out on my Pioneer pds-801 cd player which i want to use as a transport. If i use the analogue outs on the cd to the audio outs on the dac am i bypassing the dac ? and thus using the cdplayer as the dac ? which obviously is not what i want. Is it possible to buy a cable with the toslink connector on one end and a coax or rca on the other? Any advice i would be most grateful for !

Hi,

a simple "cable" will not work, as the signal has to be converted from optical (which ist red light) to electrical for the input of your DAC. There are quite a few DIY converter designs online, but if money doesn't matter you can buy them as well.

Thankyou, so it seems the only option is to buy a converter to go toslink to coax ? `can someone confirm my suspicion that using analogue interconnects will just bypass the dac ?

...yes it will!

You already named it -> "analogue interconnects"

the CDP itself contains a DAC to provide analogue output signals if you don't use an external DAC.

Connecting these analogue outputs to any device behind your DAC will bypass it and use the CDP internal DAC - the signal that comes out of the analogue outputs is already an analogue waveform, not a digital signal.

Connecting the CDP analogue outputs to the DAC analogue outputs will be even worse - you should not connect outputs to outputs, there's a good chance to damage one of the output stages!

You can also DIY a coax output in your player if you're up to a little research and your soldering is decent. Doesn't cost much.

Less than 15$ that includes the case, shipping and power supply? Probably for you or me, not for average joe that, no offense, doesn't know the difference between analog and digital outputs.

Yeah, you're right. That's hard to beat if you're not a hacker.
