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 thorough-
ly 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 devel-
oped 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 reso-
nances when using an acoustic guitar.
Before using this unit, carefully read the sections entitled: "IMPORTANT
SAFETY INSTRUCTIONS" (p. 2), "USING THE UNIT SAFELY" (p. 3), and
"IMPORTANT NOTES" (p. 4). These sections provide important informa-
tion concerning the proper operation of the unit. Additionally, in order to
feel assured that you have gained a good grasp of every feature provided by
your new unit, this manual should be read in its entirety. The manual
should be saved and kept on hand as a convenient reference.
