The FBQ2496 has line-level inputs and outputs so you cannot connect the vocal mic directly to it. You will need to route the vocal mic to an Aux output, connect that to the FBQ input and take the output to a spare XR16 input.

You should disconnect the original mic channel from the Main LR mix - open the channel Main tab and click the LR button to turn it off (grey).

Thanks Rex. How is best to configure the spare channel the FBQ is plugged into? Switch all the EQ and stuff off and set the channel gain and fader accordingly? Or is it possible to route the input channel directly to MainLR bypassing any of the channel strip?

Yes you could turn EQ and dynamics off on the FBQ return channel. You could use a pre-fader send from the original vocal channel to the Aux out so the channel fader is not used. Then the fader on the FBQ return channel becomes your vocal fader. If you reassign the channel inputs, you could have the FBQ return in the same channel position as the vocal mic input and place the vocal send channel in a less conspicuous position.

I imagine the FBQ output is a line level signal, so I wouldn't need an input with a preamp?

Hi Douglas @DB-4433 

Welcome to the forum. To be honest, most of the posting involves the digital mixers, TC Helicon products and the new synthesizers. I haven't used one of those Virtualizer Pro effects units for a number of years. But if I recall, you can only use one preset at a time. If you do want to use EQ, compressor, and other effects simultaneously, I would suggest you consider getting one of the X-Air digital consoles, such as the XR12. Each channel has a gate, EQ and compressor. Plus there are 4 FX slots that you can populate with the numerous type of FX built-in (56 to be exact). In fact the FX engine is identical to the one in the X32. 

Any luck with this?  I'm interested in both an EQ and Compressor together.  Thanks!

I am also trying to find this answer. For my new X2222usb mixer. Only one at a time, is that right? Unless  you choose a mix preset like #15 Delay-Reverb which is difficult to control. The delay (echo) goes on and on and I can't find a way to control it.

Thanks for any help!

Hi Bill ( @UUBill ), 

Welcome to the community.  Wow!  That's definitely going into my sound effects collection.  It appears you have a feedback loop somewhere in your system.   Has anything position wise changed in your setup? By position wise, I mean microphones relative to PA speakers? The first thing I'd do would be to change the meter from "Out" to "In" so you can see the levels coming in.   Next, I'd take picture of your current fader settings, then drop all of the faders to nil, and see if it still happens.  If not, bring the frequencies up a few at a time until it occurs.  That should tell you where the feedback is occuring. 

Hope this helps,

Ken
