Introduction

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 processing.

Output Setups and Speaker Compensation

The GNX4 features both 1/4” and XLR outputs on the rear panel. These jacks let you simultaneously connect the GNX4 to an amplifier/speaker system on stage via the 1/4” outputs and connect directly to your PA system via the XLR outputs. The GNX4 incorporates Speaker Compensation filtering that can be turned on or off independently for each output pair depending on your application needs.

Use the OUTPUT SETUP button along with the DA TA WHEEL to select one of the Output Setup options.

The six Output Setups are as follows:

steroall - All input sources (guitar, mic, line, drums, onboard 8-track recorder playback and USB

playback) are routed to both output pairs in stereo. 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.

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. When enabled,these inputs can be routed around or through the GNX4’s effects processing and then mixed directly into the GNX4’s 1/4” and XLR outputs.

Use the SHIFT>MIC and SHIFT>LINE buttons along with the D A T A WHEEL to select the Mic/Line Setup options.

Both Mic and Line inputs have four settings that can be independently selected. They are as follows:

MIC OFF / LINe OFF - Mic and Line inputs are disabled. MIC DRY / LINe DRY - Inputs routed directly to GNX4’s outputs, bypassing all effects processing. MIC RVB / LINe RVB - Inputs routed through delay and reverb effects of the current preset. MIC FX / LINE FX - Inputs routed through all effects of current preset.

Optimizing the Mic Input Level

To adjust the microphone input level for optimal use, you must first setup the GNX4’s Record Level meter located on the Recorder Control and USB/Signal Routing Panel to monitor the live microphone signal. To do this, follow these steps:

1.Press the SHIFT button located on the Recorder Control and USB/Signal Routing Panel and then

press the CF/USB 1-2 SRC button.

2. Then use the DA T A WHEEL to select your desired input routing source (

STEREOfx,STEROALL,

MONO fx, MONO ALL,SUM+DGTR, SUM+MIC, DGTR+MIC,or DRY MIC). STEREOfx and mono fx will

only work if the Mic Input is selected properly. (See page 64 for more information regarding the GNX4 Input Sources.) Also, if the mic is routed through

MIC RVB or MIC FX,the active effect’s

level can impact the levels shown in the meters.

3. Talk or sing into the mic as intended for use and adjust the GNX4’s Microphone Input Level knob

located on the rear panel until the level consistently lights just below the 0 dB clip point on the REC LEVEL meter. Utilize the -20 dB pad switch also located on the GNX4’s rear panel if the level is too high to provide proper headroom.

NOTE: If your microphone requires phantom power,first make sure the microphone is connected, then press the Phantom Power switch (labeled +48V) located on the rear panel of the GNX4. The +48V LED located next to the DATA WHEEL indicates the phantom power is active. If your mics don’t need phantom power, it is best to turn it off.

Optimizing the Line Input Levels

To adjust the line input levels for optimal use,you must first setup the GNX4’s Record Level meter located on the Recorder Control and USB/Signal Routing Panel to monitor the live line input signals. To do this,follow these steps:

1.Press the SHIFT button located on the Recorder Control and USB/Signal Routing Panel and then

press the CF/USB 1-2 SRC button.

2. Then use the DA T A WHEEL to select your desired input routing source (

STEREOfx,STEROALL,

MONO fx, MONO ALL,SUM+DGTR, or DRY line). STEREOfx and mono fx will only work if the Line

Inputs are selected properly. (See page 64 for more information regarding the GNX4 Input Sources.) Also, if the lines are routed through

line RVB or line FX,the active effect’s level can

impact the levels shown in the meters.

3.Play audio back from your external audio device (mixer, keyboard,CD player, etc.) and adjust its output

level until the level consistently lights just below the 0 dB clip point on the GNX4’s REC LEVEL meter.

Audio Routing Setups

For Live Performance

The GNX4 was designed to be extremely flexible to meet any of your application needs. For many GNX4 users,its primar y 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. The following diagrams show examples of how to utilize the GNX4 in typical live performance applications.

Before connecting the GNX4,make sure both the GNX4 and your amplifier(s) are turned OFF.

Small Club Setup (Mono Amp Rig)

This diagram demonstrates a minimum setup for using the GNX4 in a typical,small club performance setup. All you need is your guitar, a couple of guitar cables, and an amp. This connection scheme also applies for use with a power amp/speaker cabinet rig.

1.Connect your guitar to the GNX4’s Guitar Input.

2.Connect a single mono instrument cable from the Left 1/4” Balanced Output of the GNX4 to the

instrument input or the effect return on your amplifier.

3.Switch the GNX4’s Speaker Compensation for the 1/4” Balanced Outputs to the OFF position.

4.Press the GNX4’s Output Setup button and select “

MONO 1/4” mode using the Data Wheel.

NOTE: When using a guitar amp(s), it may be best to connect the GNX4’s Output to your amp’s effects return to avoid coloration of the tone due to the amplifier’s tone controls.

Medium Stage Setup (Stereo Amp Rig)

Whether your gig is at a large club or a small hall,nothing beats running your guitar in stereo. This diagram demonstrates a typical setup using your GNX4’s line outputs,and two guitar combo amps.

1.Connect your guitar to the GNX4’s Guitar Input.

2.Connect mono instrument cables from the Left and Right 1/4” Balanced Outputs of the GNX4 to the

instrument inputs or the effect returns on your amplifiers.

3.Switch the GNX4’s Speaker Compensation for the 1/4” Balanced Outputs to the OFF position.

4.Press the GNX4’s Output Setup button and select “

STEROAll” mode using the Data Wheel.

Large Stage Setup (Stereo Amp/Cabinet Rig)

A large stage rig lets you really pull out all the stops since space isn’t necessarily an issue,but volume usually is. For this application, plug your guitar into the GNX4 and connect mono instrument cables from the GNX4’s 1/4” outputs into a stereo power amp feeding two cabinets. Using two cabinets gives you much more dramatic stereo separation and helps widen the sweet spot for your sound when you move onstage. Another great idea is to run the GNX4’s XLR outputs directly into the house P.A.and have the sound engineer control your front of house volume in the overall mix. Then if you need to turn up your stage volume,you won’t upset him by trying to rebalance your guitar volume in the house mix. This diagram demonstrates a typical,large stage performance setup.

1.Connect your guitar to the GNX4’s Guitar Input.

2.Connect mono instrument cables from the GNX4’s Left and Right 1/4” Line Outputs to a stereo

power amplifier amplifier and switch the 1/4” Outputs Speaker Compensation to the OFF position.

3.Connect XLR cables from the GNX4’s Left and Right XLR outputs to the house P.A. mixer and switch

the XLR Outputs Speaker Compensation to the ON position.

4.Press the GNX4’s OUTPUT SETUP button and select “

STEROALL“ as the output mode using the

DAT A WHEEL.

Coffee House/Solo Performance Setup

As a solo performer, we all know how important it is to minimize the amount of gear we have to cart to a gig. For the more elaborate system, this may include electronic keyboards, a CD player,and a mixer. The GNX4 virtually eliminates the need for most of this hardware. First, for your backing tracks,just rip your CD audio tracks into MP3s and place these in the MP3 folder created by the GNX4 on the compact flash card. If you need a mic for vocals or an acoustic instrument,just plug it into the GNX4’s mic input. You have a variety of routings you can select from including taking advantage of the GNX4’s effects processing. For the more advanced setup or if you have a partner on keyboards,just plug them into the GNX4’s line inputs and select the appropriate routing needed. Everything can now be run out the GNX4’s XLR outputs directly into powered speakers. You can even run to a floor monitor out one of the available 1/4” Line Outputs and enable Speaker Compensation on both pairs of outputs.

1.Connect your guitar to the GNX4’s Guitar Input.

2.Connect a microphone to the GNX4’s XLR Mic Input use the Mic Level control knob located next to the Mic Input on the GNX4’s rear panel to adjust the microphone output level. To adjust your microphone input level for optimal use see Optimizing the Mic Input Level on page 13.

3.Connect a mono instrument cable from the GNX4’s Left 1/4” Line Output to a powered monitor.

4.Connect the GNX4’s balanced XLR Left and Right Outputs to a pair of powered PA speakers.

5.Switch the Speaker Compensation on for both the XLR and 1/4” outputs.

6.Press the GNX4’s OUTPUT SETUP button and select “

STEROALL” as the output mode using the

Presets

A preset is a named and numbered location of a programmed sound that resides in the GNX4. Presets can be recalled with the Footswitches or the DA TA WHEEL. The GNX4 comes with 80 Factor y and 80 User presets. The Factory Presets do not let you store changes to them. The User presets let you store changes. From the factory, the 80 User presets are exact duplicates of the 80 Factory presets. This lets you create your own presets without worrying about losing any of the original presets. When you select a preset,the name of the preset appears in the green display and the number of the preset appears in the red numeric display. The User LED to the left of the DAT A WHEEL lights indicating the User preset is active. The Factory LED lights indicating a Factor y preset is active and the Card LED lights indicating a preset from a Compact Flash

Memory Card inserted into the GNX4’s Memory Card slot is active.

Footswitch Modes

When you first apply power to the GNX4, it powers up in one of three Footswitch Modes:Preset, Stompbox/Control,or Recorder. The Footswitch Modes are selected in two different ways:

Press the MODE button (located to the right of the D A T A WHEEL)

Press and hold Footswitches 4 and 5 simultaneously. Depending on which mode is selected,the UP/DOWN footswitch LEDs will light a different color. When

Preset Mode is selected,the UP/DOWN footswitches will be lit green. When Stompbox/Control Mode is selected, the UP/DOWN footswitches will be lit yellow. And when Recorder Mode is selected,

the UP/DOWN footswitches will be lit red. In any of the modes,the display shows the selected preset’s name and number. The vertical LEDs on the Matrix indicate which effects are active for the selected preset.

Preset Mode

The GNX4’s Presets are grouped into sixteen banks of five presets. (See the Preset List on page 112 for a complete list of Presets with their respective Bank locations.) When Preset Mode is active the UP/DOWN footswitches are used to select one of the sixteen Factory,User,or Card Banks. Successive presses of the UP/DOWN footswitches advances through all Factory/User/Card Banks. Pressing and holding the UP/DOWN footswitches scrolls through the Factory/User/Card Banks. Once a Bank is selected,Footswitches 1-5 will flash indicating a preset within that bank needs to be selected. If a preset is not selected within 5 seconds,the GNX4 returns to the currently selected bank and preset. A second press of the same footswitch bypasses the preset. Another press reactivates the preset.

For more information regarding the footswitch functions for Preset Mode see page 59.

Stompbox/Control Mode

Stompbox/Control Mode is another mode of operation that can be used during a performance. When

Stompbox/Control Mode is active, the UP/DOWN footswitches are used to select the GNX4’s presets. Footswitches 1-4 turn the effects on and off. Footswitch 5 is used as a Tap-Tempo switch for setting the delay time during a live performance.

For more information regarding the footswitch functions for Stompbox/Control Mode see page 60.

Recorder Mode

When Recorder Mode is active, the GNX4’s UP/DOWN footswitches are used for selecting songs and loops that reside in the recorder’s memor y. The 1-5 footswitches are used for hands-free control of the recorder’s functions.

For more information regarding the footswitch functions for Recorder Mode see page 61.

Expression Pedal

The Expression Pedal can control three different parameters simultaneously in each preset. Rock the Expression Pedal back and forth to change the values of the assigned parameters. Each parameter the Expression Pedal controls has an adjustable minimum and maximum range. The Expression Pedal also includes a feature called V-Switch and when enabled, it turns on the wah effect and switches from controlling the parameters assigned to the Expression Pedal and controls the Wah. See page 45 for more information on

Expression Pedal Pedal Assignment.

About the GNX4

Bypass

About the GNX4

The GNX4 Matrix

The main panel of the GNX4 is the Matrix. The Matrix is comprised of two main sections, Amp/Cabinet and Effects. It is used to navigate through the GNX4’s amp/cabinet modeling and effects parameters. Upon power up, the GNX4 defaults to the TONE amp control row in the Amp/Cabinet section and any effects that are enabled within a preset will have their corresponding LEDs lit in the Effects section of the Matrix. You can select one of the other three Amp Control rows,CHAN 1 EQ, GENETX, or CHAN 2 EQ using the Amp Control Buttons or you can select the different effects and their parameters using the Effect Select buttons. The LED to the left of each row indicates which row is active,while the Status Button and five Knobs control the corresponding parameter above or below each knob.

Viewing/Editing GENETX™and Amp Parameter V alues

To view or edit an amp parameter’s current value,you must first select the row in which the parameter resides using the Amp Control buttons located to the left of the amp parameter rows. After selecting the desired row, use the Status Button and Knobs to adjust the parameters. When turning a knob one click position the current value of the selected parameter will show in the display. If a Knob is turned again within 3 seconds,the parameter value will be changed. If a Knob is not turned within 3 seconds, the main display returns back to the preset name.

NOTE: If a parameter name is shown in the display while editing both Amps and Effects,the DATA WHEEL can change the value as well as the Knobs.

Amp/Cabinet Modeling

The GNX4 was designed to make sound processing easy and intuitive. Because the GNX4 provides both Amp Modeling and Effects Processing,the editing functions are divided into two sections:the Amp/Cabinet Modeling section and the Effects section. The GeNetX

™

technology contained in the GNX4 lets you go much

further than mere Amp Modeling. GeNetX lets you create your own Amp/Cabinet HyperModel

™

and store this custom creation to a User Amp/Cabinet location. When editing either the Amp/Cabinet Modeling,or the Effects section,you must start with one of the User or Factory Presets. The preset you begin with does not need to be in the location that you intend to save it.

After selecting a preset,you can select the Amp Models or Cabinet Types for your preset. Amp/Cabinet Modeling applies the tone of one of several vintage or modern Amp Models and Cabinet Types to your guitar signal. The GNX4 includes accurate emulations of 15 guitar Amp Models, 10 Bass Amp Models,one Acoustic Guitar Simulation,and 22 Speaker Cabinet Types.Your choices include:

Editing Amp Models and Cabinet Types

Each GNX4 preset has three channels,Channel 1 (green),Channel 2 (red), and Warp (yellow). Amp channels 1 and 2 have selectable amps and cabinets. Each channel has independent controls for gain, level,EQ, and cabinet tuning. The Warp channel is effectively a mixture of the Channel 1 and 2 amps and cabinets using the Warp knob in the Amp Controls section of the matrix. When parameter values have changed,the Store LED lights indicating the preset has been modified and needs to be stored (see page 58 for more on the storing procedure).

Once you have selected your amps for Channel 1 and 2,you can switch between these,as well as the Warp channel,using the Amp Channel footswitch (Stompbox/Control Mode only) or the Status button (GeNetX row is active) when the preset name is displayed. The following sections guide you through the process of selecting amps and cabinets,adjusting amp parameters, performing cabinet tuning, and creating then saving a Hypermodel
