Anti-Feedback
Everyone loves that amazing squealing sound coming out of the speakers, right?
Yeah, not so much.
Anti-Feedback automatically adapts to your environment and removes
frequencies that can cause feedback. It’s not a silver bullet, you still have to set
up your gear with reasonable volume levels and avoid pointing the mic at the
speakers, but Anti-Feedback can help when you’re “on the edge” and getting
some squealing here and there.
To activate Anti-Feedback, simply press the button. White is OFF, Blue is ON.
You’ll see the LED light blue when it’s working to get rid of offending frequencies.
If the LED is flashing constantly, it’s done all it can do and you’ll have to look at
the rest of your audio setup to reduce things further.

Pitch Correction
Nobody is perfect, so we give you the option to add a little bit of transparent
pitch correction to your voice. It gently guides you to the nearest semi-tone when
you sing.
To activate Pitch Correction, press the Pitch button. White is OFF, Green is ON.
An important note about Pitch Correction: it’s normal to hear “phasing” between
your head voice (not to be confused with “the voices” in your head) and the
corrected voice coming from speakers or headphones. The collision of the
two signals creates the phased effect. Your audience (or a recording) doesn’t
experience the sound.
You can actually use the phased sound to improve your pitch over time. The less of
the phased sound you hear, the closer you are to perfect pitch.

Pitch Guide
Sometimes it’s nice to get some about your singing. With the Pitch Guide, you can
see how close to the “true” note you are when you sing. It’s great to know that
you typically sing sharp or flat, or simply struggle with a particular note or two.
To activate the Pitch Guide, press and hold the Pitch button. To deactivate the
Guide, press and hold again. When the pitch meter turns on, you’ll see the LED
ring light from red (at the bottom) to green (at the top). When the pitch meter
turns off, the LED’s will change from green to red.
The pitch guide shows whether you’re “on the note” (green LED’s), “flat” (yellow/
red LED’s on the left hand side of the ring) or “sharp” (yellow/red LED’s on the
right hand side of the ring).
