Features
Thank you for selecting the
ZOOM A2.1u
(simply called the "
A2.1u
" in this manual). The A2.1u is a
sophisticated effect processor for acoustic guitar with the following features.
●
Latest technology for top performance
Excellent sound quality is assured by signal processing circuitry featuring 96 kHz/24 bit sampling and
internal 32-bit processing. Frequency response remains flat to 40 kHz, and signal-to-noise ratio is an
amazing 100 dB or better. A built-in USB port serves for direct connection to a computer. You can use
the A2.1u as audio interface for the computer, allowing direct recording with the supplied DAW
software.
●
Full array of effects optimized for acoustic guitar
Out of a versatile palette of 47 effects, up to eight (including ZNR) can be used simultaneously. The
A2.1u offers effects which simulate the sound of famous acoustic guitars, a mic simulator that creates
the ambience of microphone recording, and other specialized acoustic guitar effects.
●
Select optimum characteristics for pickups and amps
The A2.1u allows you to select the best frequency response for your pickup and amp. This is great for
eliminating sonic problems that can occur when playing an acoustic guitar through a guitar amplifier.
●
Automatic suppression of acoustic feedback
The feedback control feature pinpoints the frequency where acoustic feedback (howling) occurs and
provides an efficient cure. The function can be activated by foot switch during a performance.
●
XLR connector for direct output
In addition to the regular output jack, the A2.1u features an XLR connector for sending a balanced line-
level signal to equipment such as a PA mixer or recording console. The signal can be derived from a
point before or after effect processing. A ground lift switch is also provided, which is useful to prevent
hum in the direct output caused by ground loops.
●
Advanced interface
Rotary selectors and three parameter knobs make operation extremely quick and intuitive. The muting
interval when switching patches has been reduced to less than 8 milliseconds, allowing virtually
seamless patch changes.
●
Rhythm function and auto-chromatic tuner
Rhythm patterns created from highly realistic PCM sources are built in. The auto-chromatic tuner
designed for guitar makes tuning easy and quick.
●
Support for foot switch and expression pedal operation
Adjust effect parameters or volume in real time with the expression pedal that is built right into the unit.
In addition, the CONTROL IN jack on the rear panel lets you connect an optional external pedal (FP01/
FP02) or a foot switch (FS01).
●
Dual power supply principle allows use anywhere
The A2.1u can be powered from four IEC R6 (size AA) batteries or an AC adapter. Continuous
operating time is approximately 6 hours with alkaline batteries.
Please take the time to read this manual carefully, in order to get the most out of your A2.1u and to ensure
optimum performance and reliability.
