I’m in need of unbalanced to balanced converters, and I’m looking at passive transformer based solutions.
I have a Denon X4200W, which is an AVR with normal RCA pre-outs
My use case is AVR->Subwoofer (long cables that do exhibit slight hum with RCA cables) and AVR->power amp (horrible hum with RCA->XLR adapters, though I still have some cables coming that need to be tried).
From what I can tell, transformer based solutions that can handle sufficient voltage (1.5 V or more) are not too common. One option I’ve found is the Palmer LI 02. The only problem that I can see is that it has a 600 ohm input impedance, which is AFAIK much lower than what is common for power amps used with AVRs.
Is a 600 ohm input impedance a problem though? Can it harm the AVR, or cause any problems with audio quality?
Alternatively, are there other solutions more suited to the task?
