Bypassing a Mixer Preamp
 

Is there a way to bypass my Touchmix8 Preamps?

I'm almost getting myself a Grace Design Felix, and I would use it preamps for my vocal mic and my acoustic guitar... But I would use my QSC Touchmix8 for mixing, live recording, effects (reverb and compressor) and fighting feedback issues.

Is there a way to use the Felix, and bypass the mixer preamp?

I strongly suspect any benefit you might theoretically achieve in a gig situation would be barely perceptible to you and totally unnoticed by anyone else in the room.

If the touchmix 8 has an effects loop, connect to the return jack. This will bypass the entire preamp.

It don't have an effects loop. :(

Sell the Touchmix!

I just don't sell it because it have a lot of nice features, such as the track live record, build in effects (comp and reverb are user in every performance), the EQ (the Felix would have EQ, too... a great one, so it is a draw), and the most important feature is the Anti Feedback Wizard, that help me A LOT in preventing to feedback in my presentations (I used to struggle with volume before feedback in the venues I was).

If it wasn't a big problem, I would use a Tonedexter in the FX loop of a Felix and would be happy forever. Hahahahahaha.
