Using both the Balanced and Unblanced inputs

It works that way on my Mk IV. But don't assume ;--) Try it, with both volumes turned down.

I had both the balanced and unbalanced inputs connected on my Basis phono stage when I was comparing cables with no problems but as Nsgarch says try it carfully.

Call the manufacturer.

I have run parallel SE + BAL systems in the past, coverging at the POWER AMP. (CDP and PHONO AMP each go se to one PREAMP and bal to a 2nd PREAMP, the first PRE goes se to my POWER AMP and the other PRE goes bal to the same POWER AMP.) I always checked in first. Some said "no sweat", others said "no way". IIRC, it's a dicier move on outputs than on inputs, but I'd spend the dime on a call to be safe.

Good Luck

It all depends on how those inputs are arranged inside the amp. IF they are connected in some way all the time (ground? or negative leg?) then the power from the one that is on can go back up the line some to the one that is off and possibley cause problems. Transistors don't like current coming in backwards. (simplistic concept but just the idea
So it can be risky (cause damage) to the other source output, even if that source is turned off.

To be sure e-mail or call Mcintosh.
