Sound Pure's Take

Condition: Used, Very Good

From Acoustic Image Amps

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 frequency 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.
