ULTRA ACOUSTIC MODELER AM400
Thank you for showing your confidence in us by purchasing the BEHRINGER ULTRA ACOUSTIC
MODELER AM400. This high-quality modelling effects pedal is designed for all electric guitar players
who want to add incredibly realistic acoustic guitar sounds to their playing. Thanks to its Real Sound
Modeling (RSM) technology that combines state-of-the-art DSP technology with sophisticated algorithms
to emulate real acoustic environments, you can create everything from standard, large-resonant,
brilliant to bright Piezo pickup simulations.
The LEVEL control adjusts the output level of the effect.
The REVERB control adjusts the amount of reverb effect that can be added to the signal.
The RES(onance) control adjusts the resonance of the simulated acoustic guitar body.
The ATTACK control adjusts the amount of attack and harmonic content of the high frequencies.
The MODE control lets you choose between four different acoustic modes:
STANDARD produces a typical acoustic guitar sound.
LARGE delivers a large, more resonant acoustic.
PIEZO simulates the distinct brightness of a classic piezo pickup.
BRIGHT gives you a brilliant and ultra-present sound, perfect for cutting through in a live environment.
The ON/BATT-LED illuminates when the effect is activated. It also serves as a battery level
Use the footswitch to activate/deactivate the effect.
Use this 1/4" TS IN connector to plug in the instrument cable.
This is the 1/4" TS OUT connector. When you only use this output, it carries the affected signal
when the effect is active, and the direct signal (without effect) when the effect is inactive—both
optimized for connecting to guitar amplifiers. When both the OUT and the DIR OUT (see
connectors are used, the OUT connector carries the affected signal optimized for connecting to
a mixer/PA when the effect is active. When the effect is inactive the OUT connector is muted.
This is the 1/4" TS DIR OUT connector, which is muted when the effect is active. When inactive
it carries the direct signal (without effect) optimized for connecting to guitar amplifiers. It works
the same way, when both the DIR OUT and the OUT (see
Use the DC IN connection to plug in a 9 V power supply (not included).
The BATTERY COMPARTMENT is located underneath the pedal cover. To install or replace the 9 V
battery (not included), press the hinges with a ballpoint pen and remove the pedal cover. Be careful
not to scratch the unit.
The AM400 has no on/off switch. As soon as you insert the jack into the IN connector, the
AM400 begins running. When not using the AM400, remove the jack from the IN connector.
This extends the life of the battery.
The SERIAL NUMBER is located on the underside.
In rare cases interferences of the normal function may appear by external influence (e.g.
electrostatic discharge), as for example sound disturbances or malfunctions. If this
occurs, please turn down the volume on subsequent amplifiers and disconnect the
input connector briefly to restart the application.
