------------------------------------------------------------------------
|
|
1) What are the PAS, PAS+, and the PAS-16?
|
|
|
|
The PAS was the original PAS card. It is capable of FM synthesizing,
|
|
and digital sound. It can do 8 bit digital sampling and 8 bit digital
|
|
playback (I don't know at what rate). The PAS has shielding built
|
|
into it that eliminates background noise that can be created by many
|
|
of the components of computer systems (hard drives for example).
|
|
|
|
The PAS+ is the new version of the old PAS. I don't believe the PAS
|
|
is for sale anymore, as the PAS+ has probably replaced it. The PAS+
|
|
is capable of FM synthesizing, and digital sound. It has the
|
|
shielding that the original PAS had. It can do 8 bit digital
|
|
sampling and 16 bit digital playback.
|
|
|
|
The PAS-16 is currently the most advanced sound card in the Pro Audio
|
|
Spectrum line. It is capable of FM synthesizing, and digital sound.
|
|
It can do 16 bit digital sampling and 16 bit digital playback. It
|
|
has the shielding that was present in the original PAS.
|
|

|
|
2) What are the specs for the PAS-16?
|
|
|
|
Here are the specs for the PAS-16. I understand that the specs for
|
|
the PAS+ are identical, except that the PAS+ can only do 8 bit
|
|
sampling, and requires you to specify when you want SB compatibility
|
|
mode on or off.
|
|
(Sorry, I don't have specs for the original PAS.)
