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.  |  IP: Logged Kishore Ghokshe Film Handler Posts: 2 From: mumbai, maharashtra, india Registered: May 2012 posted 01-19-2014 04:54 AM                        Can u give me the details of impedance converters as we are finding it difficult to get here  |  IP: Logged Sam D.

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.  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 01-19-2014 04:48 PM                     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.  |  IP: Logged Mohd Ridzuan Film Handler Posts: 25 From: K.L , Malaysia Registered: Jul 2012 posted 01-27-2014 07:47 PM                     You can use converter Ultra stereo Dax602 without CAT790. If you using CAT790 odyssey is the best solution.  |  IP: Logged
