A switch on the rear panel allows the digital audio output to be turned off if its use is not required.

Turning the digital output “off” when not using it will result in slightly higher sound quality through the analog outputs.

A second switch sets the sample rate available at the digital output. Selecting “44/48 kHz” will down-sample high sample rate (88.2, 96, 176.4, or 192 kHz) PCM discs to single rate (44.1 or 48 kHz) PCM output.

Only change the sample rate switch while the unit is powered on and no disc is playing.

If the unit is not powered on or if a disc is playing, the position of the switch will not be detected. This can lead to a mismatch between the position of the switch and the actual state of the unit.

Selecting “88/96 kHz”will allow high sample rate PCM discs to output dual-rate PCM (88.2 or 96 kHz) at the digital audio output. This higher quality format can be used with a device capable of accepting higher sample rates. Dual-rate discs will output dual-rate audio, while quad-rate (176.4 or 192 kHz) DVD-Audio discs will be downsampled to dual-rate audio.
