The meanings of these symbols are as follows: • Handling Caution This symbol indicates explanations about extremely dangerous matters. If users ignore Warning this symbol and handle the device the wrong way, serious injury or death could result. If users ignore this symbol and handle the device the wrong way, bodily injury and damage to the equipment could result. Since the GFX-4 is a precision electronic device, avoid applying excessive force to the switches and buttons. [. . . ] Use the / keys to bring up the patch name on the display. This display allows changing the patch name. The flashing character is the one that is currently selected for editing. O P Q R S T U V W X Y Z 6. When the patch level and patch name have been set, press the LEVEL/NAME key. The GFX-4 returns to the previous mode. 12 - 13). If you call up another patch in program mode without storing the current patch, any editing changes will be lost. Editing Operations Setting the ZNR Threshold The GFX-4 incorporates the ZNR (ZOOM Noise Reduction) circuit which is highly effective in minimizing noise in playing pauses. In manual mode or program mode, press the ZNR key. The indication "ZNR" appears on the display, and the current setting (oF, 1 - 10) is shown on the GROUP/BANK indicator. 3. When the threshold has been set, press the ZNR key once more. The GFX-4 returns to the previous mode. If required, store the patch. If you call up another patch in program mode without storing the current patch, any setting changes will be lost. 2. Use the L/M keys to adjust the ZNR threshold (sensitivity). Choose the value which yields the best noise reduction without causing the sound to be cut off abruptly. The setting "oF" means that ZNR is turned off. 18 ZOOM GFX-4 Using the Expression Pedal (RTM function) The GFX-4 has an integrated expression pedal that can be used to adjust the volume or effect parameters in real time. This section explains how to make RTM settings and use the function. 1. Select the patch for which you want to make RTM settings, and press the PEDAL module key in manual mode or program mode. The PEDAL module display is shown. This module serves for making expression pedal settings. Depending on which knob is operated, the parameter name appears on the display and the current setting is shown on the GROUP/BANK indicator. The RTM setting can be made in manual mode or program mode. However, if the PEDAL module key is pressed in program mode, the unit reverts to the original condition if no control is operated for 5 seconds. To use the expression pedal as volume pedal in bypass mode, the stereo output of the GFX-4 must be used. If the mono output is used (playback system connected only to the OUTPUT MONO jack), the expression pedal does not function as a volume pedal, regardless of the EXPVOL parameter setting. 2. Use the pedal module key to bring up the indication "EXPVOL" on the display. 4. Use the pedal module key to bring up the indication "EP-DRV" on the display. This display lets you make settings for using the expression pedal as a volume pedal and for selecting the function of the assignable switch built into the expression pedal. This display allows you to select the effect module to be adjusted in real time with the pedal. RTM control is possible for the DRIVE, MODULATION, and DELAY/REVERB modules. Use knobs 1 - 3 of FX panel 2 to set the following parameters. • Parameter Knob 1 • • • • EXPVOL Determines whether the expression pedal is used as a volume pedal in this patch. • Parameter Knob 2 • • • • MINVOL When the "on" setting is selected with knob 1, you can set the minimum volume (the volume when the pedal is fully raised) with this knob. • Parameter Knob 3 • • • • EXP-SW The expression pedal incorporates an assignable switch (electronic switch that is toggled between on and off when the pedal is fully depressed). This knob lets you select the function of the switch from the following two options. 0: Toggle RTM controlled module on/off status 1: Switch between program mode and manual mode 5. [. . . ] • Is mono output used (playback system connected only to OUTPUT MONO jack)? Expression pedal on/off switching is not performed properly • Readjusting the pedal may correct the problem. Readjust pedal, as described on page 28. Oscillation occurs • Is high-gain distortion effect used together with compressor/booster effect or EQUALIZER? Reduce parameter values of high-gain module (gain, tone, level).
