Hi guys,

Maybe you guys can help me with bi-amping my front JBL 4675's & 4670.
Pre/pro=Denon 2807
HF amp= L/C/R channels of an Outlaw 7700
LF amp=Monster MPA-3250

Signal from Denon is unbalanced.

I've tried several different prosound x-overs including a behringer dcx2496 digital, an analog dbx, an analog behringer, and I currently have a bbe ds48 digital. All of them have caused too much hiss.

Thinking maybe the hiss is due to trying to run a balanced pro sound x-over with an unbalanced signal I even tried my old Audio Control caraudio x-over and it hissed badly also.

Everything I've tried results in WAY too much hiss coming from the horns.

I tried various level settings such as boosting the input signal and cutting the hf outputs on the x-overs but it really didn't help. Basically with all trims on the x-over at their minimum I still hear a lot of hiss.

If i just run the signal straight from Denon right into the Outlaw(hf amp) then there's barely any hiss at all.

Both the Outlaw and the Monster have the balanced input option so would getting something like a rane balance buddy to get a balanced signal help hiss?

Thanks in advance for the help,
Ken
