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.
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.
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.

Output level indication:
Indicates signal levels of each output after all signal processing.
Output level correspond to the level scale printed at the left side of the indicator.
When OVER is lit for a long time: means that the signal is too big, can lower the input
signal;
When LIMITER is lit: means the compressor is working.
Indicates simply which output channel is fed by which input channel and the output
frequency range based on the setting of filter cut-off frequencies.
This function helps prevent speaker from being damaged as you can make sure of each
output's status when you operate RECALL or connect an amplifier and loudspeaker.
The print at the right side of the LED show each indication's meaning as follows:
IN-1,IN-2
Indicates which input's signal is the sound source. When both indicators
light up, it indicates monomixed signal is the sound source.
HF,MF,LF,SLF
Indicates the frequency range of each output channel:
HF : High Frequency; Lights up when frequen cies>=1KHz;
MF : Middle Frequency; Lights up when frequencies from 500Hz to 1KHz;
LF : Low Frequency. Lights up when frequencies from 100Hz to 500Hz;
SLF : Super Low Frequency; Lights up when frequencies<=100Hz.

Real line: before processing Broken line: after processing
Capable adjust with 15.515 sec steps at 0- 2.034seconds ( 15.515 sec is equivalent to approximately
5.275mm in the speed of sound.
NOTE:
The minimum delay time between input and output while using an analog input/output is about 1.2msend
when delay time is set at 0. This delay is caused by signal's passing through A/D, D/A converter and the
signal processor.
Capable of switching normal or inverse (180 ).
Capable of setting for each channel.
Except Muting and source of invoice is individual setting everlasting, Parameter of other channels can be
