UL TRAROC GX110
1. INTRODUCTION
Thank you very much for expressing your confidence in BEHRINGER products by purchasing the ULTRAROC
GX110. With the ULTRAROC, you have acquired a modern Guitar Workstation that sets new standards in
practice amp engineering. When developing the GX110, our top objective was to reproduce the authentic
sound of classical guitar amps as perfectly as we could and combine it with latest DSP technology – while
focusing on an user interface that can be operated intuitively.
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 no-compromise quality, fully-featured products and exemplary service – even years
after purchase – as well as sensationally low prices, which allow any ambitious music lovers to make their
musical dreams come true.
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 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 Guitar Workstation that offers you a complete set of
functions, but can still be operated intuitively and quickly – no matter what kind of style you play.
Unfortunately, conventional guitar amps are often not fully designed and developed. Moreover, many manufacturers
of traditional-style guitar amps are somewhat afraid of using state-of-the-art technology. The ULTRAROC, on
the other hand, is a pioneering guitar amp that has considerably more functions than any conventional 2-channel
amp with a built-in spring reverb. Still, you can use the GX110 so that it mimics an excellently sounding
2-channel combo amp with an – admittedly – good spring reverb (except for that “shatter” sound when the amp
gets knocked over). However, we recommend that you make yourself familiar with the ULTRAROC in full detail,
so that you know what each of the many functions does and be able to fully exploit the numerous effects and
control options provided.
As technology advances, you’ve got to keep track of latest technological breakthroughs to avoid falling by the
wayside. We, too, have continuously improved this amp 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 gave
us complete satisfaction. After all, we really want to give you fully designed and developed products that meet
your expectations in every respect. The ULTRAROC shall be an useful tool for years to come, which is why
we’ve equipped the effects modules of our Guitar Workstation 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 latest generation of guitar amps. Many people contributed to this
project of intense development: studio musicians, collectors of vintage guitar amps, music and guitar lovers
alike. We even invited guitar amp tuning experts to help us develop an amplifier that gives you the best of all
worlds:
s Sophisticated analog technology with a “feel factor” only analog technology can provide.
s The perfect emulation of tube-specific nuances to make up for the drawbacks encountered in tube designs
(noise, hum, etc.)
s Latest DSP technology to give you a broad range of modern high-gain and vintage-type effect sounds.
s Rugged and solid construction which even withstands roughest handling.
I Intuitive operation, so that you can focus your mind on what is most important to you: your music!
+ This manual first describes the terminology used, so that you can fully understand the
ULTRAROC and its functions. Please read the manual carefully and keep it for future reference.

1. INTRODUCTION
UL TRAROC GX110
1.1 The design concept
The philosophy behind BEHRINGER products guarantees a no-compromise circuit design and employs the
best choice of components. The operational amplifiers used in the ULTRAROC are exceptional: they boast
extreme linearity and very low distortion characteristics. To complement this design, the choice of components
includes low-tolerance resistors and capacitors, high-quality potentiometers and several other stringently selected
elements.
The ULTRAROC 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 super-robust steel-plate enclosure of your ULTRAROC, with its generously dimensioned power supply,
ensures that your GX110 will never fail on the stage – even when the going gets tough. The enclosure is made
of high-grade and non-polluting MDF wood, which consists of multiple tongued layers.
1.1.1 VIRTUBE technology
Tube preamps usually have three to five triode stages in series producing various degrees of distortion,
dynamic compression and frequency response modification. In addition to the characteristic curve, along
which the signal is distorted, also the order of filters and distortion stages play a vital role. While clean and
slightly distorted sounds may be a pleasure to hear when the signal has lots of bass prior to the distortion
stage, this configuration would lead to a muddy, fuzz-like sound when hi-gain settings are used. For this
reason, tube amps have passive, and usually simple filters switched between the individual amplifier stages.
These filters determine which frequencies contribute to the distorted sound.
After the distortion stages, too, filter circuits are used to provide a perfect blend of output signal and generated
harmonics. Our VIRTUBE circuits have been optimized to mimic this sophisticated interaction with solid-state
components. EQ and filters between the single stages are the same as those used in classical tube amps. The
non-linear characteristic curves are simulated by means of specific diode types. The result is an amplifier
that gives you sounds with a very pronounced tube character.
1.1.2 JENSEN loudspeaker
Since Peter Jensen produced the first loudspeakers in 1923 JENSEN reshaped the communications industry.
As the demand for new electric guitar and bass amplifiers increased, so did the need for JENSEN speakers
in the 50’s and 60’s. JENSEN represented the worldwide industry standard for speaker products and their
sound was in fact the sound of Rock ´n´ Roll. Still these vintage speakers are highly valued by top musicians
and collectors around the world. Famous american and british brands choose JENSENs for their top-of-theline products. There is no doubt about the tremendous impact the loudspeaker has on the sound of electric
guitar amplifiers. Consequently, JENSEN has put into production those legendary speakers again that
contributed so much to the history of modern music, using the most sophisticated and modern facilities
Europe has to offer. You will find them in top-of-of-the-line guitar amps.
1.2 Before you begin
Your BEHRINGER ULTRAROC was carefully packed in the factory and the packaging is designed to protect
the unit from rough handling. Nevertheless, we recommend that you carefully examine the packaging and its
contents for any signs of physical damage, which may have occurred during transit.
+ If the unit is damaged, please do not return it to BEHRINGER, but notify your dealer and the
shipping company immediately, otherwise claims for damage or replacement may not be granted.
Shipping claims must be made by the consignee.
Be sure that there is enough space around the unit for cooling and please do not place the ULTRAROC on high
temperature devices such as radiators etc. to avoid overheating.
+ Before you connect your ULTRAROC to the mains, please make sure that your local voltage
matches the voltage required by the unit!
