Sony HT-9950M Manual

The following switches the method of 
outputting audio signals when you connect a 
component such as an amplifier (receiver) or 
MD deck with a digital input jack.
For connection details, see page 20.
Select “DOLBY DIGITAL,” “DTS,” and 
“48kHz/96kHz PCM.”

If you connect a component that does not 
conform to the selected audio signal, a loud 
noise (or no sound) will come out from the 
speakers, damaging your ears or speakers.
• DOLBY DIGITAL (DVD VIDEO/DVD-

RW only)

Selects the type of Dolby Digital signal.

• DTS (DVD VIDEO/DTS-CD)
Selects the type of DTS signal.

When “DTS” is set to “DTS” and a DTS-CD is 
played back, audio signals are not output from the 
LINE OUT AUDIO L/R 1/2 jacks. When a 
component that cannot receive the stream signal of 
DTS is connected to the HDMI OUT jack, audio 
signals are not output from the HDMI OUT jack.

• 48kHz/96kHz PCM (DVD VIDEO only)
Selects the sampling frequency of the audio 
signal.

• The analog audio signals from the LINE OUT 

AUDIO L/R jacks and 5.1CH OUTPUT jacks are 
not affected by this setting and keep their original 
sampling frequency level.

• If the HDMI OUT jack is connected to equipment 

not compatible with 96 kHz/24 bit signals, 
48 kHz/16 bit PCM will be automatically output 
even when you select “96kHz/24bit.”

◆ AUDIO (HDMI)

Selects the type of audio signal output from 
the HDMI OUT jack.

• A loud noise (or no sound) will be output if you 

connect the player to a TV that is not compatible 
with DOLBY DIGITAL/DTS signals and 
“AUTO” is selected. In this case, select “PCM.”

• If you are using the HDMI OUT jack, make sure 

that “DIGITAL OUT” is set to “ON.”

D-PCM

Select this when the player is 
connected to an audio 
component lacking a built-in 
Dolby Digital decoder. You can 
select whether the signals 
conform to Dolby Surround 
(Pro Logic) or not by making 
adjustments to the 
“DOWNMIX” item in 
“AUDIO SETUP” (page 81).

DOLBY 
DIGITAL

Select this when the player is 
connected to an audio 
component with a built-in 
Dolby Digital decoder.

D-PCM

Select this when the player is 
connected to an audio 
component without a built-in 
DTS decoder.

DTS

Select this when the player is 
connected to an audio 
component with a built-in DTS 
decoder.

48kHz/96kHz PCM:

48kHz/16bit

48kHz/16bit The audio signals of DVD 

VIDEOs are always converted 
to 48 kHz/16 bit.

96kHz/24bit All types of signals including 

96 kHz/24 bit are output in their 
original format. However, if the 
signal is encrypted for 
copyright protection purposes, 
the signal is only output as 48 
kHz/16 bit.

AUTO

Normally, select this. Outputs 
audio signals according to the 
“DIGITAL OUT” settings 
(page 82).

PCM

Converts Dolby Digital, DTS, 
or 96 kHz/24 bit PCM signals to 
48 kHz/16 bit PCM.
