Cool A-Rigging Sound System

Complete Active Line Array Sound Reinforcement System.

Consists of:
• 1 active sub woofer
• 4 full range speakers
• rigging hardware

Ribbon tweeters used in this system can give a wide-range frequency response up to 40KHz, which guarantees high fidelity and even sound field. The tweeter's impedance and phase response curves are almost ideal horizontal lines. The moving mass of the transducer is as light as milligrams so that the impulse response is perfect. The distortion rate is effectively reduced due to the suspension system formed by using special thin foam rubber surround and spraying processed paper cone.

The rigging part is designed to meet different application requirement. The splay angel can be adjusted by minimum 1 degree vertically.

The active subwoofer applies low distortion technology, linear amplification 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 the subwoofer and the full-range speaker, which forms an integrated Line Arry Cluster

Active Amplifier with DSP
DSP Audio processing technology and linear amplification technology are integrated into R8 active amplifier module. The amplifier with power handling of 600W can drive 5pcs of speakers at the same time. Optimized software is applied for frequency response, delay, crossover, frequency compensation and gain control as well as compressor and limiter protection via RS-232 port connected to computer. 24 bits - AD/DA conversion technology with precise filter calculation and gain control and intelligent protection system.

Introduction of Software
Active module with built-in DSP processor can manage and adjust tweeters and woofers separately. It contains functions like gain, crossover ( high pass & low pass), equalization, compression & limitation, delay and phase inversion control. And integrated intelligent testing and controlling systems are available for equipment protection to maximum degree. 6 configuration modes can be saved in the system for convenient use at any moment.

Standard RS-232 port can be conveniently 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 and stability for long time operation.
