Default composite to XLR

I have recently run into a problem I got a pro amplifier that has some age to it (around the 60's -70's) it only has XLR input on it. My preamp only has composite jacks and I was wondering if it were possible to get the amp working without having to use opamps to transfer it to XLR.

Thanks in advance

Hi,

you can connect one side of a balanced input to ground and drive the other input.

No op-amps needed.

Sometimes amplifiers have XLR input sockets but are not actually balanced.

Hi,
look up Rane notes for interconnects and grounding.
http://www.rane.com/note110.html

Shows how to wire up an adaptor for XLR to RCA and RCA to XLR
i.e. unbalanced to balanced interconnects.
