    Optima Air Pre-amp
    NUX Optima Air is equipped with a pre-amp that allows you to enhance your sound by using a 3-band equalizer.

    The beauty of an analog circuit is that chaos makes the muse. While you tweak the knob, it affects itself and also other parameters.

    Driven by NUX's white box algorithm (physical modeling) of Neve 1073, Optima Air can replicate the chaos in a compact size, while providing lots of features like USB audio stream, Reverb function, and IR Capture.

    Editor Software
    You can load 3rd party IRs and edit preset names through editor software.

    Optima Air also supports USB audio stream, which means you could use Optima Air as recording interface. You can adjust USB AUDIO routing through editor software. For WINDOWS operating system, please download NUX ASIO Driver from SUPPORT. The editor software offers you built-in LEVEL adjust knob, so you can tweak the 3rd party IR level.


    Capturing a Guitar Profile
    Run the pedal in capturing mode; press the IR footswitch and hold, plug in the power cable.

    You need to use a condenser microphone for better result. Connect the acoustic guitar to the Optima Air's input, place the microphone and connect to a microphone to a microphone preamp. And connect the microphone preamp's output to the Optima Air's Return (Please check the picture)

    Make sure everything's connected, and you are all set to capture.

    nullYou can see the input level and the return level on the pedal screen, make sure the levels are not reaching to the MAX (Peak) level, or too low to capture it. Usually, 60% to 80% is the best level for capturing.

    You can press the IR footswitch when you are ready. It will countdown from 3 to 1 then you could start to play guitar to send the audio signal to Optima Air to capture and process. Just play as clean as you can, and use finger position or chords you are playing most of the time. Capturing record will take 10 seconds, you can also see it on the screen, the RED AMP LED will start blinking when the recording is done. You can press the AMP footswitch to save, or you can press the IR button to restart the capturing.
