LOUDSPEAKER MANAGEMENT

1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this apparatus near water.
6. Clean only with dry cloth.
7. Do not block any ventilation openings. Install in accordance with the manufacture’s instructions.
8. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers)
that produce heat.
9. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one
wider than the other. A grounding-type plug has two blades and a third grounding prong. The wide blade or the third
prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for
replacement of the obsolete outlet.
10. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the
point where they exit from the apparatus.
11. Use only attachments/accessories specified by the manufacturer.
12. Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus.
When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.
13. Unplug this apparatus during lighting storms or when unused for long periods of time.
14. Refer all servicing to qualified service personal. Sevicing is required when the apparatus has been damaged in any
way, such as power supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus,
the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.
15. The apparatus shall be connected to a MAINS socket outlet with a protective earthing connection.
16. Where the MAINS plug or an appliance coupler is used as the disconnect device, the disconnect device shall remain
readily operable.
Introduction
The symbol, wherever is appears, alerts you to the presense of uninsulated dangerous voltage inside the
enclosure-voltage that may be sufficient to constitute a risk of shock.
The symbol, wherever is appears, alerts you to important operating and maintenance instructions
in the accompanying literature. Please read the manual.
To reduce the risk of electric shock, do not remove the top cover (or the rear section). No user serviceable
parts inside. Refer servicing to qualified personnel.
To reduce the risk of fire to electric shock, do not expose this appliance to rain and moisture. The apparatus
shall not be exposed to dripping or splashing liquids and no objects filled with liquids, such as vases, shall be
placed on the apparatus.
These service instructions are for use by qualified service personal only.
To reduce the risk of electric shock do not perform any servicing other than that contained in the operation
instructions. Repairs have to be performed by qualified service personal.

Introduction
The DP Series are powerful DSP based loudspeaker processors, ideally suited for install application, where they
combine the functions of a multitude of conventional products in a compact 1U unit with extensive remote control
capabilities. To achieve this, the DP Series devices have two inputs, three inputs, and four inputs and up to eight
outputs.
Base crossover modes:
6 Outputs have 2x2 way, 2x3 way, 4+2 way, 5+1 way and 6 way.
Each output has a gain control, variable delay line, highpass and lowpass crossover filters, seven band multi-type filters,
polarity, input signal source, a limiter. The crossover filters offer slopes of up to 48dB/Octave.
Security lock-out is avaiable for each parts.
Supply external device remote controls.
Remote port is and RS485.
8 Outputs have 2x2 way, 2x3 way, 2x4 way, 4+4 way, 5+3 way and 6+2 way.
4 Outputs have 2x2 way, 3+1 way, 4 way and 2 MonoSub.
Units also offer “Source” for free assign signal, which allows completely flexible routing of any output from any
combination of inputs.
Each input has a gain control, variable delay line, multi-type filters. Filter types included parametric equalisation,
high & low shelving, notch, band-pass, all-pass, variableQ highpass & lowpass.

5. Meters: Input and Output meters show dB from clipping point. Red CLIP LED show signal overflow, Yellow LED
show signal near -3dB.
1. Power Switch: turns the device’s mains supply off and on.
2. RS232: RS232 standard via a 9 pin D-type connector, for connection to PC.
3. RS485: RJ45 style sockets. Used for transmission of remote control data over long distance or multiply device
applications.
4. Audio Inputs: 3 pin XLR sockets are provided for each channel. All are fully balanced, pin 2 hot, 3 cold, 1 screen.
5. Audio Outputs: 3 pin XLR sockets are provided for each channel. All are fully balanced, pin 2 hot, 3 cold, 1 screen.
