Unbalaned to Balanced


What would it sound like if I run an unbalance cable on my preamp(only unbalanced connections) to the balanced input on my amp(amp has a choice on Balanced or Unbalanced connections)?Ron

I use those for processor ( XLR ) to Amp. ( RCA ) for Atmos speakers.
Atmos speakers are rather small so I am not shure about the sound  quality.
I don’t ear any  ´´  hum  ´´
Hi Vinyl,
No difference. In fact, a lot of amps don't have truly balanced inputs. They ground the (-) pin. It's there for convenience.

Lots of pro amps did this, because in a studio balanced cables are the norm. 
Best,

I have just bought a ATI AT524NC power amp. I have not received it yet.
RCA. And. XLR inputs.
where do I have to look to know if that amp is truly balanced ?
In the specification ?
thanks
