1. INTRODUCTION
The BEHRINGER ULTRA-CURVEPRO is a fully digital sound processing device based on DSPs and 24-bit
A/D and D/A converters. The high speed DSPs are capable of performing any process in fractions of a second,
the only element governing their performance being the software. The enormous flexibility available means that
the ULTRA-CURVEPRO has a range of features greatly exceeding those found in a conventional analog
graphic equalizer, at a price previously unimaginable.
+ The following operational manual will introduce you to the BEHRINGER ULTRA-CURVEPRO
and its various functions. After reading the manual carefully, make sure it is always on hand
for future reference.
1.1 The design concept
The BEHRINGER ULTRA-CURVEPRO is a digital mainframe. This means that after the servo-balanced input
stage the signal is converted to digital and that all processing is done within the digital domain. After process-
ing the signal is then converted back to analog and sent to the servo-balanced outputs. With the digital input /
output option it is possible to connect a digital device to either the input or output or to both in and output.
Processing digitally gives certain advantages. What the unit does only depends on the software that runs the
device and the performance depends on the processing speed and quality of the hardware that the software is
run on. When new ideas and algorithms are developed and become available they can be implemented in the
software. It also means that the ULTRA-CURVEPRO has become more than just a very good graphic equal-
izer. It also incorporates a full parametric equalizer and several intelligent active functions like the
FEEDBACKDESTROYER, limiter, and noise-gate. It even means that the ULTRA-CURVEPRO can measure
and correct the response of the a system in a room. This gives this digital mainframe possibilities beyond
conventional analog units.
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. Two 24-bit DSPs are used as
the heart of the ULTRA-CURVEPRO. These perform the precise calculations needed for the processing of the
complex algorithms. Additionally, the ULTRA-CURVEPRO uses high quality resistors and capacitors with
very tight tolerances, high-grade switches, low-noise operational amplifiers (type 4580) as well other selected
components
The ULTRA-CURVEPRO DSP8024 uses SMD technology (Surface Mounted Device). These subminiature
components known from aerospace technology allow for an extreme packing density, plus the unit's reliability
could be improved. Additionally, the unit is manufactured in compliance with the ISO9000 certified manage-
ment system.
Fail-safe relays have been incorporated into the design of the BEHRINGER ULTRA-CURVEPRO, which auto-
matically and silently bypass the unit in the event of power supply disconnection or failure. These relays are
also active at switch-on to isolate the ULTRA-CURVEPRO until the power rails have settled, thus preventing
the possibility of a potentially damaging switch-on thump.
1.2 Before you begin
Your BEHRINGER ULTRA-CURVEPRO 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 ULTRA-CURVEPRO 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
ULTRA-CURVEPRO on high temperature devices such as power amplifiers etc. to avoid over-
heating.
