Denon POA-S10 Power Block Amp
I have 2 POA-S10 Power Block amps. They have been connected to a Denon PRA S10 Preamp. I have used these for many years with no issue. I moved the around the other day and was getting no sound from one side. On investigation I found the RCA input (Unbalanced) was loose and actually the metal housing had come totally away from the unit. The system has Balanced inputs for use with what I assume are xlr cables. I have no experience with these. I tried connecting the Balanced output from the Preamp to the balanced input of the amp and engaged the "balanced" input button on the amp. With this set up I still get no sound out of it.
Does anyone out there have any suggestion as to what I might try?
If this will not work how might I best find someone to repair that RCA input?
I am assuming it is connected to a board and I am going to have to have it reattached at best and the entire board (If I can find one) replaced at worst.
Thanks for any suggestion.
