So a bit about my scenario… I’m considering making a guitar amp for fun. I have come into some IcePower 50asx2-btl modules salvaged from Galaxy audio monitors (one was converted back to an SE by adding an inductor for home use). Now the trouble with this amplifier is that it only accepts a balanced input. I’m familiar with basic differential to balanced converter boards using opamps and such, but I’m really familiar with amplifying an unbalanced instrument signal from an electric guitar into a balanced line level signal.
Are there standalone boards that can accomplish this? Or will I need to use an instrumentation amp into a diff. to balanced board?

I have a big knowledge gap in this area, so some insight into my issue would be greatly appreciated.

Thanks
