"=>" = L/R analog
"->" = digtal
If you have CD->DAC=>568=>L/R channel amp
You could also have DVD->568=>L/R channel amp
This would use the Processor and DACs in the 568 for DVD use. The 568 internal DAC would be bypassed for CD listening and just use the 568 as a switching device. This would be true "IF" the 568 does not convert the input analog signal to digital and back to analog again.
