Introduction - Zoom G2.1u Service Manual

Introduction

The G2.1u is a multieffect processor with the following features and functions.
●Latest processing technology for outstanding performance
96 kHz / 24 bit sampling (with 32 bit internal processing) assures excellent sound quality. Frequency response
remains flat up to 40 kHz, and input-converted signal-to-noise ratio is an amazing 120 dB, demonstrating the high
level of performance achieved by the G2.1u. The G2.1u also has a USB connection and can be used as a direct
guitar/computer interface.
●Versatile palette of effects including new creations
Out of a total of 54 effects, up to nine (including ZNR) can be used simultaneously. The high-quality choices
provided by the G2.1u include distortion effects that simulate the tones of famous amps and effects pedals, 6-band
guitar EQ and delay effects with "hold" control operated by foot switch.
●Great for live performances and direct recording
The distortion effect module provides two different algorithms for each of its 17 effect types, one for live
performance and one for direct recording. Depending on the on/off setting of the CABINET & MIC effect which
simulates amp cabinet sound and mic characteristics, the most suitable algorithm is automatically selected, giving
you the best sound for any application.
●Integrated rhythm functions and auto-chromatic tuner
A number of rhythm patterns using realistic PCM drum sounds are provided. This is convenient for use as a
metronome during individual practice or to provide a simple rhythm part for a quick session. An auto-chromatic
tuner for guitar is also built right into the unit, allowing you to easily tune your instrument also at home or on stage.
●Sophisticated user interface
The combination of a rotary type selector and three parameter knobs make the effect editing process intuitive and
quick. The mute interval when switching patches has been reduced to less than 5 milliseconds. Seamless patch
changing is now a reality.
●Dual power supply principle allows use anywhere
The G2.1u can be powered from four IEC R6 (size AA) batteries or an AC adapter. Continuous operating time on
batteries is approximately 7.5 hours with alkaline batteries.
●Easy operation with expression pedal and foot switch
The expression pedal on the top panel lets you adjust the tonal quality of an effect or the volume in real time.
An optional expression pedal (FP01/FP02) or foot switch (FS01) can be connected to the CONTROL IN jack. The
external expression pedal is used for controlling the volume. The foot switch is convenient for quickly toggling
effect programs or for setting the tempo of the rhythm function.
Please take the time to read this manual carefully so as to get the most out of the unit and to ensure optimum
performance and reliability.
