Hi

I have just bought a Pioneer 656A which includes the ability to play
SACD and DVD-Audio. I have a couple of DVD-A disks with both DD51
sound and Advanced Resolution Surround and Advanced Resolution Stereo
options.

I also have a hybrid Multi-Channel SACD and a couple of hybrid stereo
SACDs.

My question is when playing the DVD-A in Advanced Resolution Surround
mode or the SACD in Multi-Channel mode, what should I have my amp. set
to?

Should it be set to Pro-Logic? I have a Yamaha DSP A1092. If I turn
the effects (DSP) mode completely off, I am pretty sure it restricts
the sound to the two front speakers.

Hopefully this is a very easy question!!

Many thanks in advance for any advice.

David
