Hi

We have installed cat790 on a cp650 processor need ur valuable suggestions on below point.
1. Need detail of option io card (specification, if possible model no.)
2. Doremi dcp2000 aes and option card pin configuration.
3. Had used a option card but getting distortion from center speaker.
4. No signals for back surrounds(right/left) through this option card.

Thanks in advance,

kishore

You should be able to find the manuals in the warehouse section. Just remember that Doremi AES output are balanced, and cat 790 are not. While (too) many people still don't install any impedance converters, ideally you should.

Can u give me the details of impedance converters as we are finding it difficult to get here

Odyessy Products makes a nice breakout board for the 650 with transformers. Take a look at their website under Odyssey Products.

A number of dealers on this site carry these boards, typically around $150.00 plus shipping.

Check this out.

One commonly used is the 650-OPTIO-AES-RJ, but you choose what you need.

Or you can fit your own impedance converters, just google it, from 110Ohm to 75Ohm.

Anyway, it should work anyway. The conversion is just a good practice and can sort some problems out.

You can use converter Ultra stereo Dax602 without CAT790. If you using CAT790 odyssey is the best solution.
