Introduction; The Design Concept; Before You Begin - Behringer Feedback Destroyer Pro DSP1124P User Manual

1. INTRODUCTION

Thank you very much for expressing your confidence in BEHRINGER products by purchasing the
FEEDBACK DESTROYER PRO DSP1124P. With the FEEDBACK DESTROYER PRO you have acquired a
highly useful device for the control of sound reinforcement systems, which will enable you to focus your
attention on what is essential: your music. The fully featured DSP1124P not only suppresses feedback but
also incorporates a wealth of additional functions in one single unit. Its 24 separate filters can be edited in all
parameters, and automatically detect and suppress feedback frequencies. With its pro-level internal
processing circuitry, the unit can also be used as a high-end equalizer for stage and studio applications. The
MIDI interface allows for integrating the DSP1124P into any MIDI system, and the open system architecture
enables you to update the system software whenever you want. In short: the DSP1124P will be your reliable
“workhorse” over many years to come.

This manual first describes the terminology used, so that you can fully understand the
FEEDBACK DESTROYER PRO and its functions. Please read the manual carefully and keep it
for future reference.

1.1 The design concept

The philosophy behind BEHRINGER products guarantees a no-compromise circuit design and employs the
best choice of components. A 24-bit DSP is used as the heart of the FEEDBACK DESTROYER PRO, which
belongs to the best components available owing to its outstanding specifications and excellent sonic
characteristics. What is more, high-quality 24-bit A/D and D/A converters ensure the accurate processing of all
signals. Additionally, the FEEDBACK DESTROYER uses high-quality resistors and capacitors with very tight
tolerances, high-grade switches, and further selected components.
The FEEDBACK DESTROYER PRO employs SMD technology (Surface Mounted Device). These subminiature
components known from aerospace technology allow for an extreme packing density and improve the unit’s
reliability even further. Additionally, the DSP1124P was manufactured in compliance with an ISO9000 certified
management system.

1.2 Before you begin

Your FEEDBACK DESTROYER 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 FEEDBACK DESTROYER PRO requires one standard 19" unit of rack space. 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 FEEDBACK
DESTROYER PRO on high-temperature devices such as power amplifiers, etc. to avoid overheating.
+
Before you connect your FEEDBACK DESTROYER PRO to the mains, please make sure that
your local voltage matches the voltage required by the unit:
The fuse holder on the female mains connector has 3 triangular markings, with two of these triangles opposing
each other. The FEEDBACK DESTROYER PRO is set to the operating voltage printed next to these markers
and can be set to another voltage by turning the fuse holder by 180°. CAUTION: This instruction does not
apply to export models exclusively designed, e.g. for 115-V operation!
Please use the enclosed power cord to connect the unit to the mains. The cord complies with all applicable
safety standards.
