Decoding the input audio
signal automatically
In this mode, the receiver automatically detects
the type of audio signal being input (Dolby
Digital, DTS, standard 2 channel stereo, etc.)
and performs the proper decoding if necessary.
This mode presents the sound as it was recorded/
encoded, without adding any surround effects.
However, when "MENU EXPAND" in the
CUSTOMIZE menu is set to "ON", "A.F.D.
2CH SW" in the SURR SET UP is set to
"CREATE" and if there are no low frequency
signals (Dolby Digital LFE, etc.) it will generate
a low frequency signal for output to the sub
woofer.
Press A.F.D. repeatedly to select "A.F.D.
AUTO".
The receiver automatically detects the type of
audio signal being input and performs the proper
decoding if necessary.
Tip
In most cases, "A.F.D. AUTO" provides the most
appropriate decoding. You may want to use SURR
BACK DECODING (page 34) to match the input
stream to the mode you prefer.
Enjoying stereo sound in multi
channel (2 channel decoding
mode)
This mode lets you specify the type of decoding
for 2 channel audio sources. This receiver can
reproduce 2 channel sound in 5 channels
through Dolby Pro Logic
DTS Neo:6; or 4 channels through Dolby Pro
Logic. However, DTS 2CH sources are not
decoded by DTS Neo:6; they are output in 2
channels.
Press A.F.D. repeatedly to select the 2
channel decoding mode.
