ULTRA-Q PRO PEQ2200
Like all BEHRINGER devices, the ULTRA-Q PRO is based on a well thought-out concept and yields excellent
technical data. Both signal-to-noise ratio, distortion products and, above all, its audio qualities have been
optimized over long-term development and testing periods. The result is a parametric equalizer of the absolute
high-end class.

The following operational manual will introduce you to the BEHRINGER ULTRA-Q PRO and its
various functions. After reading the manual carefully, make sure it is always on hand for future
reference.
2. THE DESIGN CONCEPT
2.1 High quality components and design
The philosophy behind BEHRINGER products guarantees a no-compromise circuit design and employs the
best choice of components. The operational amplifiers NJM4580 which are used in the ULTRA-Q PRO, are
exceptional. They boast extreme linearity and very low distortion characteristics. To complement this design
the choice of components includes high tolerance resistors and capacitors, detent potentiometers and several
other stringently selected elements.
For the first time, the ULTRA-Q PRO PEQ2200 uses SMD technology (Surface Mounted Device). These
sub-miniature components known from aerospace technology allow for an extreme packing density, plus the
units reliability could be improved. Additionally, the unit is manufactured in compliance with a ISO9000
certified management system.
2.1.1 Failsafe relay
A failsafe relay has been incorporated into the design of the BEHRINGER ULTRA-Q, which automatically and
silently bypasses the unit in the event of power supply disconnection or failure. This relay is also active at
switch-on to isolate the ULTRA-Q PRO until the power rails have settled, thus preventing the possibility of a
potentially damaging switch-on thump.
2.2 Inputs and outputs
2.2.1 Balanced inputs and outputs
As standard, the BEHRINGER ULTRA-Q PRO is installed with electronically servo-balanced inputs and out-
puts. The new circuit design features automatic hum and noise reduction for balanced signals and thus allows
for trouble-free operation, even at high operating levels. Externally induced mains hum etc. will be effectively
suppressed. The automatic servo-function recognizes the presence of unbalanced connectors and adjusts the
nominal level internally to avoid level differences between the input and output signals (correction 6 dB).
2.2.2 Transformer balanced outputs (Optional)
In contrast to electronic balancing, the use of transformer-balanced outputs offers the advantage of galvanic
separation between units. Electrical potential differences and ground loops in audio installations do not there-
fore impair the performance of the units. The transformer-balanced outputs, commonly used in radio and TV
engineering, can also be fitted retrospectively upon request. The BEHRINGER transformer OT-1 is designed to
the highest exacting standards and is available as an accessory.
3. INSTALLATION
Your BEHRINGER ULTRA-Q 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 ist contents for any signs of physical damage, which may have occurred in transit.
