When using stationary microphones, which will tend to cause feedback with fixed frequencies, use Single Shot mode to detect feedback frequencies and lock the frequencies until you reset them yourself.

Though the FireWire return signal cannot be routed to the AUX inputs, if users want to add additional effects to the return signal they are able to route the signal to the Control Room outputs using the “FireWire & 2T Return” button in the Control Room section.  Use the Control Room outputs to send the signal to the external processor, and return these signals through the AUX Returns as you normally would.

The traditional smiley-face curves of analog equalizers have begun to be replaced by a new generation of digital equalizers. Digital equalizers can offer more precise frequency settings as well as other options that allow users to optimize the sound mix in any given room. Regardless of what your audio needs are, chances are you will be using an equalizer in your audio chain. Using an equalizer is an effective way to help sweeten the sound of the room and reduce feedback.

Connect the microphone to your mixer, then the mixer to your i7100. The outputs of the i7100 can then be connected to an amp and speakers (or you may also like to connect the i7100 to a channel insert, if it’s easier).

1. Always try to position the speakers so that they are in front of all microphones, pointing away from them. If you point speakers back at you, it will almost certainly cause feedback. If you have to point them back at you, try to position them to point directly at the back of the mic.
2. Make sure all mics are positioned correctly. One mic out of position can cause the whole problem.
3. Listen for the frequency of the feedback and try to adjust the EQ accordingly; if you’re getting low end rumbles, turn down the bass on your mic channel or graphic EQ. If you’re getting high squeals, turn down the treble on the mic channel or graphic EQ, etc.
4. You may need to add a monitor system so that you can hear yourself better. You can power these from your mixer, or use active stage monitors, and EQ them separately from the mains in order to maximize levels before feedback occurs. Point these back at yourself at ear level and you can turn down your mains to control the feedback better.

Q: Is this preamp transparent? Can I get a vintage sound out of it? Is it warm? Is it ok if I put the mic in front of the guitar amp, or is this preamp good only for vocals?

The PPC Power Conditioner should work fine. It has a 10 amp rating, so you should first work out how many amps you need before starting. If your devices do draw more than 10 amps, the circuit breaker will trip. Otherwise, you’re fine.

Q: Is it possible to run a send and return on the AUX channel so that all channels are affected by the effect? Can I use a chaos pad to affect the main out channels by coming out the control room channel, through the chaos pad and back into the mixer through regular channels?

Q: Can I use the i7200 as a passive crossover? To clarify, I want to put the i7200 between my amplifier and speakers.

You would connect the EFX or AUX send of the mixer to the input of your effects unit and the output of the effects unit to the EFX or AUX return on the mixer. If you want to get only the effected sound returned , set the balance on the effect unit to 100% effects, without any direct signal mixed in.
