GUITAR AMPLIFIER

OWNER'S MANUAL

We’d like to take a moment to thank you for purchasing the Roland AC-100 Acoustic Chorus guitar amplifier. We hope you’ll take the time to thoroughly read through this owner’s manual. It will help you fully appreciate all the great features of the AC-100 and help to ensure that the unit provides you with years of trouble-free service.

Features

•The AC-100 is optimally designed for both acoustic and electro-acoustic guitars. The amp includes digital effects that make use of Roland’s DSP technology to provide fat choruses and deep reverbs.

•The Chorus effect provides more warmth and creates a greater sense of spaciousness compared with conventional effects thanks to a newly developed technique of sound imaging which separately outputs the various frequency ranges of the sound.

•The AC-100 features a Tri-Amp system that uses three two-way speakers to accurately reproduce the sound of an acoustic guitar.

•The MIC/AUX CHANNEL and GUITAR CHANNEL are each equipped with a dedicated preamp, thereby allowing simultaneous use of a guitar and microphone. This also makes it possible to set up a wide variety of systems that include (for example) a recording device or rhythm machine.

•The GUITAR CHANNEL includes a SHAPE switch that lets you create a wide range of sounds suitable for an acoustic or electric guitar.

•The AC-100 features an Anti-Feedback circuit to eliminate unwanted resonances when using an acoustic guitar.
