Enjoying Dolby Digital
and DTS surround sound
(A.F.D. mode)
The A.F.D. (Auto Format Direct) 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.
Press A.F.D. repeatedly to select
the sound field you want.
For details, see “Type of A.F.D. mode” (page
70).
You can also select “A.F.D.” in the Sur Settings
menu. For details, see “Settings for the
surround sound (Sur Settings menu)” (page
59).
Notes
• This function does not work in the following cases.
– MULTI IN is selected.
– Input signals of which the sampling frequency is
more than 48 kHz are being received.
• If you set up the sound field during DTS 96/24
signal reception, it will play back only at 48 kHz.
Tips
• We usually recommend “A.F.D. AUTO,” however
sometimes it may be better to use “SB
DECODING” (page 60) to match the input stream
to the mode you prefer.
• You can identify the encoding format of DVD
software, etc., by looking at the logo on the
package.

• Only Dolby Pro Logic IIx decoding is effective,
when a multi-channel signal is input.
At this time, the setup of “SB DECODING” and
“SB DEC MODE” in the Sur Settings menu
becomes invalid. When you select decoding modes
other than Dolby Pro Logic IIx, multi-channel
sound (being encoded) is output.
If you connect a sub woofer
This receiver will generate a low frequency
signal for output to the sub woofer when there
is no L.F.E. signal, which is a low-pass sound
effect output from a sub woofer to a 2 channel
signal. However, the low frequency signal is
not generated for “Neo:6 Cinema” or “Neo:6
Music” when all speakers are set to “LARGE.”
