BEHRINGER is an audio engineering company that has been successfully developing products for studio and live applications for many years now. Our range of products includes microphones and a variety of 19" devices (compressors, enhancers, gates, tube processors, headphone amps, digital effects devices, DI boxes etc.) as well as various monitoring and P.A. speakers plus professional live and recording consoles. The name of BEHRINGER stands for
We also set great store by flexibility, which has become a particularly important factor in the music business over the past few years. Modern guitarists and musicians need to offer a broad range of sounds, but should still be able to play in different kinds of applications at short notice: home recording, studio, live concerts. For this reason, it has always been our prime concern to give you a maximum of functions that can still be operated intuitively and
As technology advances, you’ve got to keep track of latest technological breakthroughs to avoid falling by the wayside. We too have continuously improved the ULTRACOUSTIC and included many of your valuable suggestions. We have spared neither expense nor effort to test different types of circuitry and speakers until the results have given us complete satisfaction. After all, we really want to give you fully designed and developed products that meet your expectations in every respect. The ULTRACOUSTIC shall be a useful tool for years to come, which is why we’ve equipped the effects modules of our entire guitar amplifier series with EPROMS that can be updated. In this way, we can keep working on new algorithms and considering your ideas and suggestions. The resulting software updates will be made available for free on the Internet, so as to ensure that your amp will never be outdated.
We’ve packed our entire experience into this

1.1 The design concept
The philosophy behind BEHRINGER products guarantees a
The ULTRACOUSTIC uses SMD technology (Surface Mounted Device). These subminiature components adapted from aerospace technology allow for an extreme packing density to further improve the overall reliability.
The
1.1.1 Tube emulator
A special FET circuit in your ULTRACOUSTIC emulates the positive characteristics of a tube exciter, producing additional harmonics and a subtle compression effect which gives your guitar sounds the power to make themselves heard and adds sustain and definition. Acoustic guitars, in particular, with their wide dynamic range, need to produce a homogeneous sound image in all registers. The FET circuit makes sure that even the high registers have sufficient sustain and won’t get drowned. While the WARMTH control allows you to add the tube sound effect as desired.
