R ibbon tweeters used in this system cangive a wide-range frequency response up

to 40KHz, which guarantees high fidelity

and even sound field.

The tweeter's impedance and phase responsecurves are almost ideal horiz ontal lines. The

moving mas s of the transducer is as light as

milligrams so that the impulse response is

perfect !

The distortion rate is effectiv ely reduceddue to the suspension system f ormed by

using spec ial thin foam rubber surround

and spraying proc essed paper cone.

The rigging part is desi gned to meet differentapplication r equirement. The splay angel can

be adjusted by minimum 1 degree vertically.

The active subwoofer applies low distortion technology, linearamplification technology, and DSP audio processing technology.

Input signal is amplified by the built-in pre- amplifier, then processed

and distributed by DSP, finally output via power amplifier to thesubwoofer and the full-range speaker, which forms an integrated

Line Arry Cluster

With 4 P urchase Full-rang Sp eakers

Active Subwoo fer With DSP

This product is main ly designed for high grade venues, like the big

meeting room, multifunctional hall, church,l uxuryb ig o rsuperci nemain family and other places. This system includes a active subwoofer

and four pieces full range cabinets with passive crossover inside.

It can be extended according to different applications.

Introduction of Software

Active module with bui lt -i n DS P processor can manage

and adjust tweeters and woofers s eparately. It contai ns

functions li ke gain, crossover ( high pass & low pass),

equalization, com pression & limitation, delay and phase

invertion c ontrol. And integrated intelligent testing and

controlling sy stems are available for equipment protection

to maximum degree.

Several opti onal filters are available for different unit

configuration and application.

6 configura tion modes can be saved in the sy stem for

convenient use at any moment.

Latest recomm ended software for system configurati on

can be downloaded from the website.

Standard RS-232 port can be conveni ently used

to connect the system to PC for DSP presetting

and parameter adjustment.

Metallic case shielding DSP module eliminates

interference from small signal processing circuits

and also helps keep connectors in good sealed

condition.

The combination of big aluminium radiator and

stageless & brushless fans forms an effective

cooling system which guarantees safety andstability for long time operation.
