Introduction
The IK Multimedia Z-Tone DI is an advanced direct box and preamp designed for guitar and bass players. It offers unique tone-shaping capabilities and flexible re-amping options, allowing you to capture both processed and clean DI tracks simultaneously. This manual provides comprehensive instructions for setting up, operating, and maintaining your Z-Tone DI.
Product Overview
The Z-Tone DI features a robust metal construction and intuitive controls for optimal sound manipulation.

Setup
Powering the Unit
The Z-Tone DI can be powered via 9V battery or 48V phantom power from a connected mixer or audio interface. Ensure the power source is correctly connected before operation.
Connecting Your Instrument
Connect your instrument (guitar or bass) to the INPUT jack using a standard 1/4" TS instrument cable.
Connecting to an Audio Interface/Mixer
For recording, connect the BALANCED OUT (XLR) to an XLR input on your audio interface or mixer. Alternatively, use the UNBALANCED OUT (1/4" TS) for unbalanced connections.
Using the Link Output (Re-amping)
The LINK output allows you to send a clean, unprocessed signal to an external amplifier or pedalboard while simultaneously sending the processed signal to your interface. Connect the LINK jack to your amplifier's input or the first pedal in your pedal chain.

Operating Controls
Gain Control
Adjust the GAIN knob to set the input level. The LED indicator next to the gain knob will illuminate green for a healthy signal and red if the signal is clipping. Adjust the gain to ensure the LED remains green during playing, occasionally flashing red on peaks.
Active/Passive Pickup Selector
Use the ACTIVE/PASSIVE switch to match the impedance to your instrument's pickups. Select ACTIVE for instruments with active pickups and PASSIVE for instruments with passive pickups. This optimizes the signal for the best tone.
Z-Tone Knob
The Z-TONE knob allows you to continuously vary the input impedance from 1 MΩ (SHARP) to 2.2 kΩ (BOLD). This unique feature interacts with your instrument's pickups, altering the tone and feel. Experiment with different settings to find the sweet spot for your instrument and desired sound.
Pure/JFET Channel Selector
The PURE/JFET switch selects between two distinct preamp circuits:
- PURE: Provides an ultra-linear, transparent sound, preserving the natural tone of your instrument.
- JFET: Engages a Class A JFET input buffer, adding subtle harmonic enhancement and a warm, tube-like character to your sound.
Ground Lift Switch
The GND LIFT switch disconnects the ground connection between the Z-Tone DI and the connected equipment. Use this switch to eliminate hum or buzz caused by ground loops.
Pad Switch (-20dB)
The PAD -20dB switch attenuates the output signal by 20dB. Engage this switch if the output signal is too hot for the input of your audio interface or mixer, preventing clipping.
Maintenance
To ensure the longevity and optimal performance of your Z-Tone DI, follow these maintenance guidelines:
- Keep the unit clean and free from dust. Use a soft, dry cloth for cleaning.
- Avoid exposing the unit to extreme temperatures, humidity, or direct sunlight.
- When not in use for extended periods, remove the 9V battery to prevent leakage.
- Handle all cables and connectors with care to prevent damage.
Troubleshooting
No Sound Output
- Check all cable connections to ensure they are secure and correctly plugged in.
- Verify that the Z-Tone DI is receiving power (either from a 9V battery or 48V phantom power). The "ON" LED should be illuminated.
- Ensure the input gain is set appropriately and not too low.
- Check the input selection on your audio interface or mixer.
Hum or Buzzing Noise
- Engage the GND LIFT switch to break potential ground loops.
- Ensure all power cables are properly grounded.
- Check for faulty cables or connections.
Distorted Sound
- Reduce the GAIN knob on the Z-Tone DI.
- Engage the PAD -20dB switch if the output signal is too strong for your interface's input.
- Check the input levels on your audio interface or mixer to prevent clipping.
