I cannot get the optical out to work from the G08. Is this a setting? The light is working but no sound I send.
Hi Coeno
If you have bought a 568 it is probably still set up for the previous owner's system, so you may find that none of the sources have the Optical input designated as the active connector as currently configured.
If you want to evaluate the G08 via each of it's connections, you can set it up to do so via analogue, SPDIF and Optical simultaneously.
Using the legacy setup programme, go into the page for Sources, and set CD for the Optical input via the drop down input menu. Then choose any two other sources, make one of them A1 input for connection to the G08 analogue output, and make the other D1, D2, D3 or D4 input, for connection to the G08 via SPDIF.
You may want to check if the G08 digital output is upsampled all the time, or if there's a choice in it's own set up menu. If it's outputing 16 bit, follow Steve's advice above and set the Optical and SPDIF inputs on the 568 for 16 bit precision, under the tabs for the two source labels which you've chosen. If the G08 is sending out 24 bit (I presume it will if it's sending 88k) then set the 568 for 24 bit input precision. Getting this right can make quite a difference to the sound.
