NUX NAI-5 Optima Air｜Acoustic Simulator & Preamplifier｜Acoustic Simulator & IR Loader

The Optima Air is an acoustic guitar tone simulation effect processor designed for acoustic guitars and paired with a preamplifier.

After the sound of the guitar is picked up using magnetic or piezoelectric pickups, the signal enters the OPTIMA AIR.
We can use pre-set models to change the tone of the guitar to classic acoustic guitar tones such as Martin, Taylor, and Gibson.

You can also use your electric guitar to simulate the tone of these acoustic guitars through the OPTIMA AIR!

It also has an internal box sampling function!
If you have an acoustic guitar on hand, he can also help you record it.
When performing outside, you can use your electric guitar to simulate the tone of your acoustic guitar without having to carry multiple guitars!

Features

• IR function
  Optima Air includes 15 IR settings.
  Each IR file contains the guitar type and pickup type.
  The IR profile name includes the guitar setup profile, optimized guitar type, and pickup type. Press the IR footswitch to turn the IR function on/off.
  
• Air preamplifier
  The Optima Air comes equipped with a preamplifier featuring gain and three-band equalization.
  His brilliance lies in our use of NUX's latest TS/AC-HD physical modeling algorithm to simulate the EQ circuit of the classic Neve 1073 microphone preamp.
  The classic analog circuit analogy states that adjusting a single parameter will cause subtle changes in the overall tone. NUX's TS/AC-HD algorithm recreates this characteristic by modeling the original circuit, allowing you to have the same captivating tone as in the recording studio.
