Axe I/O Solo Combines IK's 2 Decades of Innovation in Analog Modeling and Hardware Design to Make Recording Guitar Faster, Easier and Better Than Ever.

Your Guitar's Golden Channel:
- Axe I/O Solo offers a triple-topology instrument input designed to preserve your guitar's unique character, combined with powerful tone-shaping features to adapt to any guitar or bass, and helps you coax a wider range of sounds from any instrument.

Pick Your Pickup:
- Passive: Designed to accommodate everything from low-output vintage pickups to hotter modern humbuckers with ultra-low noise and extended frequency response
- Active: Bypasses unnecessary gain stages when using active pickups, to keep your signal path as direct, transparent and clean as possible

Choose your channel:
- Pure: A completely transparent and ultra-accurate preamp circuit that won't color your sound in any way
- JFET: A Class A JFET input buffer for subtle harmonic enhancement, midrange focus and warmth

- Axe I/O Solo also offers IK's patent-pending Z-Tone® circuit, letting you dial in impedance from 1 M Ohm ("sharp") down to 2.2 k Ohms ("bold") that interacts with your pickups.
- At the maximum impedance, you'll find your sound tighter, sharper and more precise. Increase the load and the sound becomes thicker and bolder. 
- You'll quickly find yourself using these controls to give your guitars even more sonic character – with just a few minutes' experimentation you can dial in a sound that fits the mix beautifully.

Pure Mic Preamp for Transparent Recording:
- Axe I/O Solo offers a high-definition, Class A mic preamp designed for transparent and clean recording. An extended, flat frequency response captures the full tonal range of your voice or instrument without coloring the sound, and best-in-class dynamic range ensures ultra-quiet recordings.

Tone Modeling and Reamplification Made Easy:
- Axe I/O Solo also includes a dedicated Amp Out so you can create the perfect tone models of your amps and pedals using Tonex for Mac/PC. Or process your recorded tracks using real guitar amps and stomps without the need for external accessories (and without having to unplug your gear). This low-noise output also eliminates ground loops during amplification and tone modeling to keep your high-gain amps as quiet as possible.
- It's simple: Connect the Amp Out to your amp, then mic it up using Axe I/O Solo's microphone preamp. Now you can create a perfect tone model using Tonex for Mac/PC. Capture a clean copy of your signal while recording and feed it back to your amp afterwards to experiment with different amp, stompbox and microphone settings without re-recording countless takes.

A Truly High-End Audio Interface for Everybody:
- The original Axe I/O set a high bar for sound quality. Axe I/O Solo preserves the best-in-class dynamic range, ultra-low self-noise and wide, extended frequency response essential to capturing the most accurate details of your performance, and for keeping your sound completely pure and transparent.
- Axe I/O Solo offers separate master & headphone volume and a monitor knob to blend direct signals and the audio from your computer for zero-latency monitoring.
- 24-bit, 192-kHz conversion and an ultra-stable, low-jitter internal clock ensures the highest fidelity, delivering truly professional-grade recordings for everyone.

Advanced Digital Control & Routing:
- Axe I/O Solo also includes a powerful, convenient Control Panel application to manage inputs & outputs and assign routing & controller inputs.
- In the Interface tab, you can view the active inputs, enable phantom power and control the ground lift to dial in the least noise for your setup. Adjust output volume, direct-monitoring routing, select the sample rate and more.
- The Controller tab gives you control over the 2 controller inputs. Set behavior, MIDI channel, MIDI CC #, minimum and maximum values, and more, to dial in the best settings for any application you want to control.
- The Axe I/O Solo Control Panel lets you keep focused on your work, instead of adjusting settings on the unit itself, for a faster, freer workflow.
