Zoom GFX-707 User Manual

This module contains a 4-band equalizer for making tone adjustments. The equalizer has only one effect type, but because there are
many parameters, it is divided into two pages titled EQ P1 and EQ P2. (Use the MODULE / keys to switch between pages.) This
module also comprises the ZNR settings.
The original noise reduction developed by Zoom cuts noise
during performance pauses without impairing the sound quality.
Adjusts ZNR sensitivity. The recommended approach is to set the
value as high as possible without producing an unnatural cut of
the instrument sound. When set to "oF", ZNR is disabled.
ZNR operates independently of the EQ module. The ZNR
setting will be active also if the EQ module is off, and the EQ
module and ZNR can also be used together.
This page of the 4-band equalizer allows adjustment from the
extreme high range to the midrange.
Controls boost/cut in ultra high range (center frequency 8 kHz).
Controls boost/cut in high range (center frequency 3.125 kHz).
Controls boost/cut in midrange (center frequency 800 Hz).
This page of the 4-band equalizer allows adjustment in the low range.
1 selects the ultra low range (center frequency 63 Hz) and 2 the
low range (center frequency 125 Hz).
Controls boost/cut in the range selected with LOW F.
Adjusts volume level after passing EQ module.

Effect Types and Parameters
In this section, all effect types and parameters of the GFX-707 are explained. Parameters that are the same for several
effects are explained in detail only the first time they appear.
The [ ] mark indicates that this parameter can be assigned to the expression pedal ( p. 22).
The - marks indicate parameters that can be controlled with the parameter knobs 1 - 3 in play mode.
