Welcome to Acoustic Image!
You have purchased a state-of-the-art musical instrument amplifier, combining purity, power and portability in a package that sets a new standard in high
fidelity amplification.
Each of our designs is engineered to accurately reproduce the sound of
acoustic and electric instruments, delivering flat frequency response across
the entire musical spectrum; extended, tight, well-controlled bass; and
complete clarity of sound reproduction.
This manual provides operating information for your Acoustic Image Clarus
1, Clarus 1R, Clarus 2, Clarus 2R, Clarus SL, Clarus SL-R, Focus 1, Focus
1R, Focus 2 or Focus 2R.
The Basics
All Acoustic Image integrated amplifiers are based on a superb class-D power
amp that delivers 300 Watts into 2 ohms (Clarus amps), 350 Watts into 2 ohms
(Clarus SL amps) or 600 Watts into 4 ohms (Focus amps) and on a
sophisticated, sensitive preamplifier. The features of the preamp and the
power amp configuration define the specific amp model.
The power amp is a high efficiency design that requires no external heat sinks
or cooling fans and is capable of driving loads as low as 2 ohms (4 ohms for
Focus amps). AC power and output speaker jacks are located on the rear of
the enclosure. A standard, three-prong detachable AC power cord is used
to provide power to the unit, while an AC voltage selection switch allows the
unit to operate at 115V/60 Hz or 230V/50 Hz.
Depending on the model chosen, your preamp offers an instrument channel
alone or instrument and microphone channels, with or without an 8-program
digital reverb (the Clarus SL·R uses the same reverb with three program
options). All of our preamps incorporate a four-band EQ per channel, high
and low impedance instrument inputs (to optimize the sound of piezo-type
pickups), an effects loop with return level control, and a selectable notch/high
pass filter for feedback control and reduction of low freqency boominess-along with a direct out capability with ground lift and a master level control. The
Clarus SL’s do not have the return level control, notch/high pass filter or the
direct out ground lift.
Yours is a high fidelity amplifier with full-range frequency response and low
distortion and noise that will accurately amplify your sound. Onboard EQ is
sufficient to overcome room acoustics and subtly shape the sound of your
instrument. However, you should note that our amps are not designed to play
at tonal extremes or with a distorted output. To achieve these, use an external
effects box.
