Sony str-da3600es User Guide

The Auto Format Direct (A.F.D.) mode allows you to listen to higher fidelity sound and select the 
decoding mode for listening to a 2 channel stereo sound as multi-channel sound.

• This function does not work when the multi-

channel input is selected.

• “Multi Stereo” does not work in the following 

cases.
– The multi-channel audio signals are being 

received.

– Dolby TrueHD, or Linear PCM signals with a 

sampling frequency of 176.4 kHz and higher are 
being received.
