4. Setup

4.1. Hardware Connection

Connect the AXE I/O One to your computer using the provided USB-C to USB-A cable. If your computer only has USB-C ports, you may need a USB-C to USB-C cable or an adapter (not included). The device is bus-powered, so no external power supply is needed.

4.2. Driver and Software Installation

Register your AXE I/O One on the IK Multimedia website using the provided registration card. Follow the instructions to download and install the necessary drivers for your operating system (Windows/Mac) and the included software (AmpliTube 5 SE, TONEX SE, Ableton Live Lite).

4.3. DAW Setup

Once drivers are installed, open your Digital Audio Workstation (DAW) software. Navigate to the audio settings or preferences and select "AXE I/O One" as your input and output device. This ensures your DAW recognizes the interface for recording and playback.

5. Operating Instructions

5.1. Front Panel Controls

• Input Gain: Adjusts the input level for your instrument or microphone. Monitor the LED indicators to avoid clipping (red light).
• Z-TONE Control: This knob allows you to continuously vary the input impedance from 'Sharp' (1 MOhm) to 'Bold' (2.2 kOhms). This interacts with your guitar's pickups to dramatically shape your tone.
• Active/Passive Switch: Select 'Active' for instruments with active pickups to bypass unnecessary gain stages, ensuring a clean signal. Select 'Passive' for passive pickups, which adds a clean gain boost.
• JFET/Pure Switch: 'Pure' offers a transparent and ultra-accurate tone. 'JFET' adds a Class A JFET input buffer for subtle harmonic enhancement and warmth, mimicking tube-like tones.
• Monitor Control: Blends between the direct input signal ('Direct') and the playback signal from your DAW ('DAW') for zero-latency monitoring during recording.
• Headphones Volume: Adjusts the output level for the headphone jack.
• Master Volume: Controls the overall output level to your studio monitors.
• 48V Phantom Power: Activates 48V phantom power for condenser microphones connected to the combo input.

5.2. Front Panel Connections

• Combo XLR/Instrument Input: Connect your guitar, bass, or microphone here. This input automatically detects whether an XLR or 1/4" jack is inserted.
• Headphone Output: Connect your headphones for monitoring.
• Amp Out: A dedicated output for re-amping. Send your recorded dry guitar signal to an external amplifier or pedalboard for further processing, then re-record it.

5.3. Rear Panel Connections

• USB-C Port: Connects to your computer or iOS device for data and power.
• MIDI In/Out: Connect MIDI keyboards, controllers, or other MIDI gear.
• SW/Pedal 1 & 2: Two controller inputs for connecting expression pedals or single/double switches for hands-free control of software parameters.
• Out 1/L & Out 2/R: TRS outputs for connecting to your studio monitors.

6. Software Integration

The AXE I/O One comes with a powerful suite of software to enhance your recording experience:

• AmpliTube 5 SE: A comprehensive guitar and bass tone studio with a vast collection of virtual amps, cabinets, stompboxes, and effects.
• TONEX SE: Create hyper-realistic Tone Models of your own gear or explore thousands of Tone Models on ToneNET.
• Ableton Live Lite: A lightweight version of the popular DAW for recording, arranging, and mixing your music.

Utilize ToneNET to explore and share presets, expanding your sonic palette with a community of users.

8. Troubleshooting

• No Sound/Input:
  • Ensure the AXE I/O One is properly connected via USB and powered on (LEDs illuminated).
  • Check all cable connections (instrument, microphone, monitors, headphones).
  • Verify that the AXE I/O One is selected as the input/output device in your DAW's audio settings.
  • Adjust the Input Gain, Monitor, Headphones, and Master volume knobs on the interface.
• High Latency:
  • In your DAW's audio settings, try reducing the buffer size. Lower buffer sizes reduce latency but may require more CPU power.
  • Use the 'Direct' monitoring option on the AXE I/O One to monitor your input signal with zero latency.
• Distortion/Clipping:
  • Reduce the Input Gain on the AXE I/O One until the clip indicators no longer light up red.
  • Ensure the Active/Passive switch is correctly set for your instrument's pickups.
• Microphone Not Working (Condenser):
  • Activate the 48V Phantom Power switch on the interface.

9. Maintenance

To ensure the longevity and optimal performance of your AXE I/O One, follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to clean the exterior of the unit. Avoid abrasive cleaners or solvents.
• Storage: Store the device in a cool, dry place away from direct sunlight, extreme temperatures, and humidity.
• Handling: Avoid dropping the unit or subjecting it to strong impacts. Do not attempt to open the casing or modify the internal components.
