Nux NAI5 Optima Air Acoustic Guitar Preamp/DI with IR Loader

The Nux Optima Air is a dual-switch acoustic guitar simulator with a preamp for acoustic and electric guitars. It simulates any acoustic guitar tone, and converts it into an IR file with the best-optimized sound, depending on your guitar and pickup type.

NUX Optima Air has a unique profile capture function, so you can create your own acoustic guitar profile (IR file) by capturing your favorite acoustic guitar's sound. The IR loader is combined with a pre-amp that allows you to fine-tune your sound with a 3-band equalizer. There’s also an extra one-knob-control Reverb Effect. Attach any effect pedal using the SEND/RETURN effect loop, and add the Optima Air into the signal chain.

There is an XLR DI output for direct line/mixer connection, headphones output for silent play, and auxiliary input to connect and play along to a music player.

  • IR Level: Adjusts the simulated signal (Impulse Response file)
  • LEVEL Select (Push to Save): In manual mode, you can choose the IR file. And you can save your customized preset by pushing the knob
  • Gain: Adjusts the signal input Gain level

  • Preset Mode: Bank Down. Also, if you are editing a preset, you can push the IR footswitch to exit without saving

AMP Footswitch:

Great little box

By: on 2 March 2022
I did some research before purchasing and was happy to discover that the Optima Air gave a better result than the more expensive comparative items. Very happy with the sound I get (ridiculously much better than the quacky piezo sound of a plugged in acoustic!) and easy to use. Also, I know there's no guarantee of shipping times with all the covid delays, but I was happily surprised to receive it the day after ordering it.
