Page 19: Audio Routing Setups
Audio Routing Setups Setups Introduction The GNX4 is equipped with four inputs and four outputs that can be configured several different ways for both live and recording applications. These settings determine which pair of outputs the mic, line, and guitar processing are routed to and how the mic or line inputs are routed through the GNX4’s effects... - Page 20 Audio Routing Setups - All input sources (guitar, mic, line, drums, onboard 8-track recorder playback and USB playback) are routed to both output pairs in mono. Speaker Compensation can be turned on and off independently for either the 1/4" or XLR outputs using the Speaker Compensation switch associated with each pair on the rear panel.

Page 22: Mic And Line Setups
The Mic and Line Setups are configurations for the mic and line inputs designed for both live performance and recording applications. The GNX4 acts as a mixing device for mic and line sources, and can eliminate the need for a mixer when the GNX4’s outputs are to be plugged directly into a full-range powered speaker system. -

Page 24: Making Connections
Making Connections For Live Performance The GNX4 was designed to be extremely flexible to meet any of your application needs. For many GNX4 users, its primary purpose will be for use in live performances. Whether you are a solo performer who spends weekends playing at a small club or the power-user playing the largest venues each night, the GNX4 has just what you need to do the gig right. -

Page 44: Effects And Parameters
Effects and Parameters Effects and Parameters The GNX4 features a comprehensive set of effects for creating just the sound you need for any musical application. These effects are connected in a standard effects chain with pickup simulator, wah, compressor, Whammy™/IPS, and distortion stompbox effects placed before the amps. Effects placed post amp are those that typically sound best when heard in stereo like modulation effects, delay and reverb. -
Page 45: Effect Definitions
GNX4 works. Preset Levels The GNX4 presets each have an independent level control for quick balancing of the levels between presets. Preset Level is accessed by selecting the Wah – Pickup row of the Matrix using the Effect Select buttons and then adjusting Knob 5. -

Page 56: Amp Channel Footswitch
From the factory, the Amp Channel Footswitch selects between the Channel 1 Amp, Channel 2 Amp, and the Warped Amp state when the GNX4 is in Stompbox/Control mode. However, you can configure the function of the Amp Channel Footswitch within a preset. -
Page 57: Lfos
A minimum and maximum value can be assigned. For instance: if the Amp Gain was assigned to LFO1, and the minimum value was set at 1 and the maximum value was set at 99, the GNX4 would automatically sweep the amount of distortion from clean to distorted and back to clean. Individual LFO speeds can also be assigned. -

i cant get any sound out of my gnx4 work station what am i doing wronge
Possible issues causing no sound from the DigiTech GNX4 workstation include:
1. Incorrect output routing – Ensure "Stereo All" or "FX" is selected in the Output Setup.
2. Playback only available on USB 1-2 – If using USB 3-4, no playback will occur.
3. Mono/Stereo mismatch – Set tracks to mono or stereo correctly in the track settings.
4. Line inputs not selected properly – Ensure correct input source is selected using the DATA WHEEL.
5. Phantom power issues – If using a mic that doesn’t need phantom power, turn off +48V to avoid problems.
6. Audio conflict – Disable theater audio driver in the video card if there's a conflict.
7. System not rebooted – A reboot may be required to resolve device recognition or routing issues.
