1.0 Introduction
Welcome! You’ve joined the group of people that have chosen high quality Community
loudspeaker systems, accessories, and components for over 35 years. We’re really gratified
you did and we will do our best to make sure you are satisfied with your new DXP4800 digital
system controller. In order for you to get the most effective use of this product please take a
few minutes to read this manual. We have included a great deal of useful information that will
help you to realize the best performance, operation, sound quality, and reliability from your new
controller. This manual contains information for the proper set-up and operation of the
Community DXP4800 controller. While every attempt has been made to ensure this information
is correct and up to date, Community continuously incorporates worthwhile improvements to
each product which may include changes and/or modifications not contained in this manual.
The DXP4800 is a complete 4 input - 8 output digital loudspeaker management system
designed for the touring or fixed sound installation markets. The absolute latest in available
technology is utilized with 32-bit (40-bit extended) floating point processors and high
performance 24-bit Analog Converters. The high-bit DSP prevents noise and distortion induced
by truncation errors of the commonly used 24-bit fixed-point devices. A complete set of
parameters include I/O levels, delay, polarity, 6 bands of parametric EQ per channel, multiple
crossover selections and full function limiters. Precise frequency control is achieved with its 1
Hz resolution. Inputs and outputs can be routed in multiple configuration to meet any
requirements. The DXP4800 can be controlled or configured in real time on the front panel or
with the intuitive PC GUI accessed via the RS-232 interface. Software upgrade for CPU and
DSP via PC keeps the device current with newly developed algorithms and functions once
available. Multiple setup storage and system security complete this professional package.
The Community DXP4800 is inherently rugged and is carefully packed in well designed cartons.
It is a good idea to carefully inspect the unit after it has been removed from the packaging as
sometimes there is hidden damage due to some unfortunate incident during shipment. Please
note that once the shipment has left Community (or the dealer), the responsibility for damage is
borne by the freight company. This means that if there is damage, you must file a claim with the
freight company. Each freight company has its own set of regulations that must be followed and
forms that must be filled out. Therefore, the freight company must be contacted as soon as a
shipping damage problem is discovered. Save the carton and packing material because many
damage claims will be considered invalid if these are thrown away. The Community dealer and
the factory will try to help in any way possible. Remember, though, it is up to the party receiving
the shipment to file a damage claim.
It is always a good idea to keep the carton and packing material in case the unit must be
shipped back to your dealer or country distributor.
