PCM/MPEG/DOLBY setting

[Slalomguy]

Hi all,

On the setup menu of my separate digital tuner there is the option of PCM
,MPEG2 or Dolby D.
Which setting do I use?
I do not have a surround reveiver,audio output from the tuner is via rca
cables directly to the TV

PCM = a single RCA-style port that carries the signal for all sound
channels.
Dolby Digital = usually a single optical port that provides digital
transmission of all sound channels.

If your TV only has RCA ports for left/right audio, then you won't be using
either PCM or Dolby Digital. I'd have to see your tuner's manual to
determine what they mean by "MPEG2", but that's probably the option you
want.

No. PCM is an encoding method for digitizing audio signals without
compression. The port you refer to is a coaxial digital audio port,
which can carry any type of digital audio. Coaxial and optical digital
audio connections are functionally the same.

Again, no. Optical ports, like coax ports, can carry any digital audio,
be it Dolby Digital, DTS, or PCM.

These settings shyould apply only to the digital audio outputs on your
tuner. Since you are not using them, the settings shouldn't matter.

There may be another menu section to control the nature of the signal
being sent to the analog audio outputs, which you are using. Make sure
this are set to "downmix" or "stereo." Likely this is done
automatically, however.

In your case it doesn't matter the setting only applies to the digital out.

MPEG2 is the standard that is being adopted by sat companies.
Dolby digital is the standard sound format for the new HDTV standard, but
not every station is broadcasting in 5.1 yet, which means that you will most
likely get dolby digital 2, which is just dolby 2 channel.
My local CBS station broadcasts most of the time in dolby dig 2, but when
theres 5.1 programming they switch to that
