Control is on the what now?

Posted by Legendre on January 3, 2005 at 13:51:44:
Ok, I've really mangled this thread.. Don't know what I was thinking but when I saw 'CDP', I thought Passive Volume control. (Yes, I am the brain specialist!)
Essentially, I gave the correct answers, to the wrong question.
If you have a CDP (CD Player, doh) that does volume control in the digital domain, or does it in the analog domain *before* a line-amp output, there should be no real problems with running a nominal length of interconnect (2-3 meters) direct into one of our amps.
If the CDPs output is balanced, find out (from the manufacturer) if it is designed to drive 600ohms. If so, terminate the input of the amp at 600ohms and see how you like it.
Standard method is to simply add a 600ohm device across pins 2 & 3 of the XLR input. You can also try using two 300ohm resistors, one each on pin 2 & pin 3, tied to ground on the other end. Depending on how your XLR cable is constructed (use of shield / drain wires etc) one setup may work better for you than the other.
Sorry for the blinding confusion on my end,
Bill
