When standard 2 channel stereo sources are
input, the receiver’s bass redirection circuitry
will be activated. The front channel bass
frequencies will be output from the sub woofer.

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, 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.
