• Turn down your PA when making all connections.
• The USB connection does not provide power to the unit.
• If you hear hum from your PA or amp, push the GRND in. Otherwise, it should remain out.

1. Turn down your PA's master volume.
2. Connect your mic, PA and AC adaptor to Correct XT as shown in the diagram. For live performance, a USB connection to a computer is not required.
3. Sing into your mic while adjusting the Input control so that the level LED flashes amber on peaks.
4. Set remaining knobs to center detent and ensure only the 2 Adaptive buttons are lit. Press the Tone footswitch so it's LED lights.
5. Sing while turning up your PA volume to a comfortable level. There will be a brief adaptive period as you sing then your voice will sound brighter and lightly compressed. From here you can experiment with the features of Correct XT.

Tone - The Tone footswitch activates the Shape and Dynamics processors which produce a "studio" vocal sound. Shape is a single-knob, multiband EQ that removes muddy lows due to microphone proximity effect while adding silky brightness. The Dynamics feature uses a high quality compressor and de-esser to tame volume peaks in both vowel sounds and sibilants (sss sounds). Warmth is a part of shape that boosts low frequencies for added warmth without muddiness.
Adaptive Shape and Adaptive Dynamics - Typically the two Adaptive LEDs should be lit so that Shape and Dynamics are tailored to your specific voice and it's moment to moment requirements. For example, a woman singing high in her range farther from the mic requires different EQ and compression than a deeper male voice singing right on top of the mic.
Pitch Correct - This helps you to be more aware of your singing pitch as well as to nudge you gently closer to being in-tune. It's like a metronome for singers. Your pitch is instantly compared to the notes in a chromatic scale (all notes are valid) and quickly shifted closer to the nearest semitone. The Pitch knob controls the speed and amount of correction. The center detent setting is the most natural sounding while still providing useful correction. Note that you will hear the effect; it is similar to chorusing but this is only heard by you and perhaps anyone nearby who can hear both your natural voice acoustically and your amplified and pitch-corrected voice.
Gate: This auto gate reduces mic level when you're not singing. It can be useful for reducing feedback as well as to minimize instrument leakage through the PA via your mic.
Anti-Feedback - Auto: This feature provides extra protection from squeals and rings during performance once you've followed the Tips for Avoiding Feedback listed below. To enable automatic antifeedback turn the Anti-FB LED on and the Manual LED off. This algorithm constantly looks for pure feedback tones caused by your mic and will engage one of its nine filters for each frequency up to nine in total. The bands are extremely narrow to minimize degradation of your vocal tone when and if they become active. If all nine bands become allocated, further feedback will cause Correct XT to turn down the volume of your mic by 3 dB once only. At this point, you should turn your PA/monitors down and reset the filters (see below).
Anti-Feedback - Manual: When this button is lit, anti-feedback problem frequencies will only be detected and eliminated when you press both footswitches together. Manual mode may work better when there are instruments in your band capable of pure tones such as Rhodes or flute which could fool the Auto algorithm.
Anti-Feedback On/Off & Reset: The Anti-FB button can be toggled to compare pre and post antifeedback sound if desired. Holding the Anti-FB button when it's LED is lit initializes all filters.

Anti-FB off & Reset can both induce feedback.
