ULTRAMIZER PRO DSP1424P
1. INTRODUCTION
The BEHRINGER ULTRAMIZER PRO is a digital sound processing device based on a sophisticated DSP,
using 24 bit A/D and D/A converters. The high speed DSP is capable of performing the calculations needed for
the complex algorithms in fractions of a second, the only element affecting its performance being the software.
Despite extensive computing work which is done in the DSP1424P by a dual-engine 24-bit processor, the
ULTRAMIZER PRO can be operated easily and conveniently. All parameter edits are performed with the jog
wheel (rotary control). 50 presets are available to store user-defined programs.

The following operational manual will introduce you to the BEHRINGER ULTRAMIZER PRO
and its various functions. After reading the manual carefully, make sure it is always on hand
for future reference.
1.1 The design concept
Contrary to analog technique, which has a limited response time capability, digital technology can look ahead
to anticipate changes in incoming signals. The longer the look ahead, the more intelligent the response of the
device or algorithm used.
You probably have heard a voice or solo instrument disappearing after a strong bass drum or bass line. This
is a typical problem experienced by virtually every compressor. The level of a sound signal is mostly deter-
mined by the bass signals. When the bass rises above the set threshold value of the compressor/limiter, the
unit will reduce the gain, which is another way of saying that the overall level will be reduced to prevent the
signal from becoming too strong. With that reduction in level, all other components like voices and instruments
will also be reduced in level, making the sound muddy and dull.
This drowning out of voices and other instruments can be avoided if the frequency spectrum is divided in two
parts. Each section can then be compressed or limited individually. The signals from the different compressors
are then added up again to make up the complete spectrum again.
The ULTRAMIZER PRO divides the spectrum into two bands prior to performing the dynamic functions. This
enables a very musical and effective compression of the program material signal. On top of that, the
ULTRAMIZER PRO also features a highly effective denoiser, an accurate and fast peak limiter, a 3D surround
processor and a new super bass/exciter for both low and high frequencies.
The philosophy behind BEHRINGER products guarantees a no-compromise circuit design and employs the
best choice of components. Top-quality 24-bit AD/DA converters which belong to the best components avail-
able owing to its outstanding specifications and excellent sonic characteristics. A 24-bit DSP is used as the
heart of the ULTRAMIZER PRO. It performs the precise calculations needed for the processing of the complex
algorithms. Additionally, the DSP1424P uses resistors and capacitors with very tight tolerances, high-grade
switches, low-noise operational amplifiers (type 4580) as well as other selected components
The ULTRAMIZER PRO uses SMD technology (Surface Mounted Device). These subminiature components
adapted from aerospace technology allow for an extreme packing density, improving the units reliability even
further. Additionally, the unit is manufactured under ISO9000 certified management system.
1.2 Before you begin
Your BEHRINGER ULTRAMIZER PRO was carefully packed in the factory and the packaging was 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 in transit.
+
If the unit is damaged, please do not return it to us, 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.
The BEHRINGER ULTRAMIZER PRO fits into one standard 19" rack unit of space (1 3/4"). Please allow at
least an additional 4" depth for the connectors on the back panel.
+
Be sure that there is enough space around the unit for cooling and please do not place the
ULTRAMIZER PRO on high temperature devices such as power amplifiers etc. to avoid over-
heating.
