Selecting the sound field

This receiver can create multi channel surround sound. You can select one of the optimized sound
fields from the receiver’s pre-programmed sound fields.

Press SOUND FIELD +/– repeatedly to select the sound field you want.

You can also use 2CH/A.DIRECT, A.F.D., MOVIE (HD-D.C.S.) or MUSIC on the receiver.
You can switch the output sound to 2 channel sound regardless of the recording formats of the
software you are using, the playback equipment connected, or the sound field settings of the
receiver.
Note
You cannot select “A. DIRECT” when you select BD, DVD, GAME, USB, AirPlay, HOME NETWORK and
SEN as input.
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.

Enjoying Sound Effects

2 channel sound mode

2CH mode Effect
2CH ST. (2ch Stereo) The receiver outputs the sound from the front left/right speakers only. There is
no sound from the subwoofer.
Standard 2 channel stereo sources completely bypass the sound field processing
and multi channel surround formats are downmixed to 2 channels.
A. DIRECT (Analog Direct) You can switch the audio of the selected input to 2 channel analog input. This
function enables you to enjoy high quality analog sources.
When using this function, only the volume and front speaker level can be
adjusted.

Auto Format Direct (A.F.D.) mode

A.F.D. mode Effect
A.F.D. AUTO (A.F.D. Auto) Presets the sound as it was recorded/encoded without adding any surround
effects. However, for USA and Canada models, this receiver will generate a low
frequency signal for output to the subwoofer when there is no LFE signals.
MULTI ST. (Multi Stereo) Outputs 2 channel left/right signals from all speakers. However, sound may not
be output from certain speakers depending on the speaker settings.
