2> INTRODUCTION

Thank you for your purchasing of the DEVICE digital speaker processor. This processor builds on the advanced and experienced ideas of design and marketing, the excellent audio performance and competitive quality/price ratio make sure your interests.

This unit DEVICE , can provide two channel analog precise signal the precise digital control. She has audio

processor and audio management functions. It can be used to the middle/small sound reinforcement system. And can be used a monitor to monitor to monitor the working issues. RS-485 PC port is provided for use with proper software system. So it is fit for the large avenue systems. The front panel interface allows quick access to all parameter by indication functions: Full control is also available via MIDI input and output jacks. Also indicate each channel configure information (Sound resource, subwoofer, low frequency, middle frequency and high frequency). Numeral remote ID or current users serial number. Setting ID or transfer user's program is available by touching front panel buttons.

2.1 Audio Features The DEVICE utilizes state of the art DSP technologies, beginning with 24bits, 64kHz delta-sigma A/D converters, with 32 bits floating points DSP. Digital processing includes Gain, Polarity Invert, Parametric EQ, Shelving Filters, Time Delay, Crossover Functions (Butter worth/Bessel/Linwitz), Compression, Limiting, and Signal Routing. All inputs and outputs are precision balanced and RF protected using standard XLR connectors.

DIGITAL SPEAKER PROCESSOR

2.2 User Interface

Front panel interface:

LED dynamic indicate, Limiting function indication, Users Program configure indication. Mute input/output indication button, Current program number and Unit ID indication. Front panel operation/running, and Remote ID Changing function button.

Control system software:

The computer interface uses SYSTEM SOFTWARE for Windows98, which allows complete PC control through an USB serial port. The system software is supplied with each unit, or can be downloaded at no cost from the web site. Advantages of using the software include greater preset capacity, and a very intuitive visual representation of the audio routing and control process.

2.3 Other Features

Having 50 groups of configure programs, and accessory with audio equipment.

3> UNPACKING

As a part of our system of quality control, every product is carefully inspected before leaving the factory to ensure flawless appearance. After unpacking, please inspect for any physical damage. Save the shipping carton and all packing materials, as they were carefully designed to minimize the possibility of transportation damage should the unit again require packing and shipping. In the event that damage has occurred, immediately notify your dealer so that a written claim to cover the damages can be initiated. The right to any claim against a public carrier can be forfeited if the carrier is not notified promptly and if the shipping carton and packing materials are not available for inspection by the carrier. Save all packing materials until the claim has been settled.

DIGITAL SPEAKER PROCESSOR

4> AC POWER REQUIREMENTS

Note: The 115V/230V switch is built in the DEVICE to avoid damage caused by wrong operation. The default set is 230V before leaving factory. If the local voltage is 115V,please open the cover and set the switch at 110V under disconnecting the ac. If the fuse is damaged, please replace the same type and rating fuse.

Instruction: The show on the switch is standard. As above diagram, the show is 230V on switch, it means the current ac voltage is 230V.

10> FREQUENTLY QUESTIONS SOLVING

10.1 Audio relevant question

DIGITAL SPEAKER PROCESSOR

Disconnect

Panel button operation error

No Sound output

Overload indicator

is flashing often

Sound default

Noise

Check the power cord is connected well or not? And the power button on the front panel is turn on or not?

Check the lock button on the panel is flashing or not. And unit is locked status or not.

Check the input/output is silent or not? The plus of input/output is weak or not? Check the selection sound source of each output channel. And confirm whether have signal to relevant input channel. If finished setting the crossover, confirm the closed frequency of high filter is lower than the closed frequency of low filter.

Whether the input signal is over strong? (The max input signal is over 20dBu or not?). Whether the plus of Input/output increased much? Check the plus of parameter increased much.

Check the crossover setting if want output full range signal.

Check whether the setting of input signal and plus is limited. And will get more plus from output. So do not try to adjust much the plus of the equipment and filter. That will caused the output noise being strong.

10.2 RS-232/RS-485 connecting problem

1). Check all the connecting wires, and make sure these are standard wires. Please check the back plate connecting terminal definition for the reference of connecting standard.

2). While many machines are connected with the head line(485), Please check the address pins of the machines, and make sure no conflict.

3). Check the USB port, Keep the hardware and software are in the same port.
