ZOOM / AC-2 Acoustic Creator アコースティックギター用プリアンプ

A high-quality preamplifier with the "acoustic remodeling" function that reproduces the natural body sound of an acoustic guitar, which is lost by passing it through the pickup.

■ Acoustic remodeling
16 built-in source guitar presets that simulate the acoustic characteristics of an acoustic guitar depending on the body material, shape, and structure. Dreadnought, round shoulder, orchestra, 12 string guitar, nylon guitar, upright bass, etc., select a preset according to the guitar you are using, and select the type of pickup (piezo/magnetic) to get the natural tone of the guitar.

The beautiful and rich sound of acoustic instruments can be played from the PA speakers on the live stage.

■ Preamplifier with DI function
The "AC-2" is a pre-amplifier for acoustics that can accept piezo, magnetic, and passive type pickups. DI function that can be directly connected to a PA mixer, 3-band EQ that allows tone adjustment according to the environment, reverb that adds depth and breadth to the sound, S/N ratio 120 dB/noise floor -100 dBu ultra-low noise design, etc. for live use It provides a full range of basic performance as an acoustic preamplifier and DI pedal.

■ Smart volume control
The newly developed VOLUME control equipped with "AC-2" adjusts both input gain and output level to appropriate levels at the same time with a single knob (patent pending). Musicians on stage can easily and smartly adjust the volume with simple operations.

■ Effectively suppress feedback
By pressing the anti-feedback switch, the frequency that causes the feedback is automatically detected, and the band is cut pinpoint with a sharp filter.
Quickly and effectively eliminates the feedback that often occurs during live performances of acoustic instruments, while minimizing changes in sound quality.

■ Ttuning
Built-in chromatic tuner with a high-brightness LED meter that can be activated immediately with a foot switch. On the live stage, you can always tune without stress.
