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.

1. Mute keys - Mute/Unmute input and output channels. When an input channel is muted, a
red LED will come on for indication.
2. Gain/Menu keys - Selects the corresponding channel for the LCD menu display and is
acknowledged by a green LED. The last modified menu will be displayed on the LCD.
Linking multiple channels is accomplished by pressing and holding the first channel key,
then pushing the other desired channels. This eases programming for same parameters
across multiple channels. Multiple Inputs can be linked together and multiple Outputs can be
linked together. Inputs and Outputs are linked separately.
3. Peak Level LED - Indicates the current peak level of the Signal:
Signal (-42dB), -12dB, -6dB, -3dB, Over/Limit. The Input Over LED references to the
device's maximum headroom. The Output Limit LED references to the threshold of the
limiter.
4. LCD -Shows all the necessary information to control the unit.
5. Rotary Thumb Wheel - Changes parameter data values. The wheel has travel velocity
sensing which eases large incremental data modifications. For modifying delay and
frequency (1 Hz resolution), pressing the Speed key simultaneously will
increment/decrement the data value by 100X.
6. Menu Control keys - There are 6 menu keys: <<Menu (Menu Down), Menu>> (Menu Up),
<<Cursor (Cursor Down), Cursor>> (Cursor Up), Enter/Sys/Speed and Exit. The function
of each key is explained below:
<<Menu: Previous menu screen
Menu>>: Next menu screen
<<Cursor: Previous cursor in the menu screen
Cursor>>: Next cursor in the menu screen
Enter/Sys/Speed: Enter is used only in the System Menu to proceed with selected
actions.
Sys enters the System Menu from the main menu.
Speed modifies delay and frequency (1 Hz resolution mode)
data values by 100X.
Exit: Exit to the Main Menu

5.0 Powering Up the Device
After powering up the unit, the following initialization screen is displayed on the LCD:
** COMMUNITY ***
** DXP4800 CONTROLLER ***
------ INITIALIZING ------
The initialization process takes about 8 seconds and during that period the unit boots and
displays the DXP4800 firmware version. After the initialization process is finished the DXP4800
displays its main screen:
** COMMUNITY ***
******** DXP4800 ********
PROGRAM:01 XXXXXXXXXXXX
The screen shows the current program number and program name assigned to the unit. The
program assigned is always the last program the user recalled or stored before powering down
the unit. Now the DXP4800 is ready to operate.
6.0 Operating the Device
Tips: Channel Linking - If the user presses one of the Input or Output Menu keys, holds it down
and presses any other Menu key(s) in the same group (Input or Output group), then the
channels are linked together. The green menu LEDs for the linked channels are lit. Any
modification of the data for the selected channel will be applied to the linked channels as well.
To cancel the linking, just press any other Menu key or the Sys key after releasing the held key.
6.1 Input Menus
Each of the DXP4800 input channels has a separate Menu key. There are 3 menus for each
input channel.

8.0 PC Control Software
The DXP4800 is shipped with a special PC Graphic User Interface (GUI) application - XLink.
XLink gives the user an option to control the DXP4800 unit from a remote PC via the RS232
serial communication link. The GUI application makes it much easier to control and monitor the
device, allowing the user to get the whole picture on one screen. Programs can be recalled and
stored from/to the PC’s hard drive, thus expanding the storage to become virtually limitless.
XLink software can also be downloaded from Community’s website at www.loudspeakers.net.
