The CP55 is one of the few analog Dolby processors that I know nothing about. Does it support both Dolby A and Dolby SR internally, or is it one or the other, or with an external box for both, like the CP50?

What is the difference, functionality wise, between the CP55 and the CP65?

The CP-55 will do fake SR with the Cat 222SR/A card, or can use the SRA5 externally with real SR. The CP-65 has slots for Cat 300/350 cards internally.

If you are doing video, don't get a CP55. It is nontrivial to modify it to send a non-sync signal through the matrix and subwoofer.

They also need an upgrade for split surrounds, if it will be used with a DA20 or DTS unit.

For most uses, a CP65 would be a better choice now, if something more modern is not an option.
