2. Acoustic Amp Product Overview
The AC601/AC101 acoustic amp is a high-quality acoustic guitar amplifier with a solid-state preamp and an analog power amp, which delivers 250W of
power into a 4 ohm cabinet, or 150W into an 8 ohm cabinet.
The AC601 features one custom-designed 6” B&C neodymium speaker and one HF Compression driver.
The AC101 includes instead one custom-designed 10” B&C neodymium speaker and one HF Compression driver.

INPUTS
The ¼” INPUT JACK (1) connects your guitar to channel 1.
The INPUT JACK (2) connects your instrument to channel 2, and accepts a balanced XLR input, in case your guitar’s pickup supplies a balanced output.
You can also use this input to plug in a microphone—even while you play your guitar through the ¼” input!
GAIN and MASTER
There are three knobs on the front panel of the AC601/AC101 acoustic head that control the volume of your instrument. The GAIN (3)(4) control
determines how much signal is passed through the preamp stage of the unit, which includes equalization and the effects loop. The MASTER (17) volume
regulates how much output comes out of the power amp into your cabinet.
If playing through the amp causes the blue CLIP (5)(6) light to turn on at all, you should turn down the GAIN (3)(4) control to avoid distortion.
When you first plug into the amp, start with the GAIN (3)(4) and MASTER (17) controls set at their lowest levels, in other words turned all the way
counter-clockwise. Then, turn your instrument’s volume up to its full level and play as hard as you do in your most aggressive moments, and turn up
the GAIN (3)(4) control until the blue light starts illuminating. Next, back off on the GAIN (3)(4) just enough so that the light stays off as you
play. This method will result in the optimal gain setting for the instrument you’re playing. Different guitars have different output levels, mostly
depending on their pickups and onboard preamp and EQ settings.
Once you’ve set the GAIN (3)(4) level, use your MASTER (17) knob to control the volume of your instrument.
