Guitar Profile Capture.
Start the pedal in capture mode; press and hold the IR footswitch, connect the power cable.
It is necessary to use a condenser microphone to get the best result. Connect the acoustic guitar to the Optima Air input, position the microphone and connect it to the microphone preamp. And connect the microphone preamp output to the Optima Air Return.
You can see the input signal level and the return level on the pedal screen, make sure that the levels do not reach the maximum (peak) value or are not too low (usually 60-80% is the best level to capture).
Press the IR switch when you are ready. After counting from 3 to 1, you will be able to start playing the guitar to send the audio signal to Optima Air for capture and processing. Just play as cleanly as possible and use the finger positions or chords you play most of the time. The capture will take 10 seconds, the red AMP LED will start flashing when the recording is completed. You can press the AMP footswitch to save or press the IR button for a new recording.
