Sony R-DG1200 Operating Instructions Manual page 60

Notes
• This function does not work in the following cases.
– The multi channel input is selected.
– DTS-HD signals with a sampling frequency of
more than 48 kHz are being received.
– Dolby TrueHD signals with a sampling
frequency of more than 48 kHz are being
received.
– PCM signals with a sampling frequency of more
than 96 kHz are being received.
– DTS 96/24 signals are being received.
• Neural-THX is activated as a PCM signal when a
sampling frequency of less than 48 kHz, a 2
channel analog signal or Linear PCM signals are
input. The Neural-THX processing will be turned
off automatically when another type of signal is
input. The beginning of the sound may drop out
when the SURROUND processing is turned on/off.
Tips
• You can identify the encoding format of DVD
software, etc., by looking at the logo on the
package.
• Dolby Pro Logic IIx decoding is effective when a
multi channel signal is input.

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 "Neo:6 Cinema" or "Neo:6
Music" 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.
