I've seen three seemingly different Ultra Stereo processors in our circuit:

JS-220
JS-120
JR-220 (or 120 possibly, I don't have the list in front of me)

I know about the J2-220, as I have 9 of them at Lakeville, what are the differences between these?

The basic difference between all the USL JS-series models is what cards are inside them.

All can be made into JSX-1000's simply by changing out (or adding, if missing) the proper cards.

The JS-Series manual should have a chart inside of it that shows which models have what cards in them (and what cards to get to upgrade a lesser JS processor into a JSX-1000) [Smile]

Arron is correct. Steve, if you need more clarification you can e-mail me.

Also not that it applies here but within the JS line are several different motherboards and chassis
The original JS didn' do SR or split surround and in the later ones there has been several revisions and the THX version is different too I beleive

Aaron,
Yes, I do have the JS series manual, and I understand how the addition of cards changes the model number. What I'm asking about is the difference between JR and JS models. All the JR models I've seen seem to be older models. Are the capabilities of the JR more limited than the JS?
