If you connect a subwoofer

This receiver will generate a low frequency
signal for output to the subwoofer when there
is no LFE signal, which is a low-pass sound
effect output from a subwoofer to a 2 channel
signal. However, the low frequency signal is
not generated for “NEO6 CIN” or “NEO6
MUS” when all speakers are set to “Large”.
In order to take full advantage of the Dolby
Digital bass redirection circuitry, we
recommend setting the subwoofer’s cut off
frequency as high as possible.

Notes on sound fields

• Depending on the speaker pattern settings,
some sound fields may not be available.
• You cannot select PLIIx MV/MS and PLIIz
at the same time.
– PLIIx MV/MS is available only when the
speaker pattern is set to a setting with
surround back speaker(s).
– PLIIz is available only when the speaker
pattern is set to a setting with front high
speakers.
• The sound fields for music and movie do not
work in the following cases.
– DTS-HD Master Audio, DTS-HD High
Resolution Audio or Dolby TrueHD with
sampling frequency of more than 48 kHz
are being received.
– “A. DIRECT” is selected.
• “PLII MV”, “PLIIx MV”, “PLII MS”,
“PLIIx MS”, “PLIIz”, “NEO6 CIN” and
“NEO6 MUS” do not work when the
speaker pattern is set to 2/0 or 2/0.1.
• When one of the sound fields for music is
selected, no sound is output from the
subwoofer if all the speakers are set to
“Large” in the Speaker Settings menu.
However, the sound will be output from the
subwoofer if
– the digital input signal contains LFE
signals.
– the front or surround speakers are set to
“Small”.
– “MULTI ST.”, “PLII MV”, “PLII MS”,
“PLIIx MV”, “PLIIx MS”, “PLIIz”,
“HD-D.C.S.” or “P. AUDIO” is selected.
