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 DATA WHEEL to select the Mic/Line Setup options.

Audio Routing Setups

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 DATA 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 DATA 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.

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

DATA WHEEL.

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.
