Hi Daniel,

I was getting the raised level through all the channels I tried. Both the ones with preamps and the ones without.

Hi Daniel,

That's the odd thing for me. I know the rear inputs don't add gain yet there was. I used both a mic requiring phantom power and one not. Both had gain on them thru the rear inputs with out any preamp applied. I tried different pres. It just seems very strange. Could it be a faulty machine?

Thanks.

Hi rwa,

First, you should not connect an outboard preamp output to the FF800 preamp input. Only use the rear panel inputs for line level signal.

Next, there is only a rudimentary level matching system for these rear panel inputs. Typically, choose +4 or -10 for these based on the outboard device output level. +4 would be a good choice if the preamp is outputting balanced audio, and you're using a TRS/XLR cable.

If the level is still too hot coming in, even after matching levels between the preamp and the Fireface, then you have to control this level at the preamp output stage.
