Sound reinforcement system System Description: The sound design, audio-visual effects to achieve basic ground floor of Building --1 multifunction multimedia presentations, theater and theater-speak sound big Wuhan Gene Technology Co., we adopt 5.1 channel Dolby surround sound design, equipped with the United States "MONTANA" manufacturers of SR-810 single 10-inch main speakers one pair, SV-410 single 10-inch center / surround speakers each one right, and subwoofer SR15B 1 pair. While matching "MONTANA" M-700 and R-550 main amplifier subwoofer amplifier 1 units and M-500 amplifier 2. Supplemented by "PATNOR" Timing power station equalizer 1s, "YAMAHA" MG166CX mixer a professional digital marshalling station and other audio processing equipment. Uniform clear, soft and delicate, open and full, endowed with dynamic sound, and no shortage of expressive and shocking sound field environment, and can effectively suppress feedback built in the existing sound condition, prevent whistle, highly reduced guarantor sound and music sex. Features 90 ° x 70 ° dispersion angle is designed for short-range sound projection distance language class conference room audio, can be used in sports stadiums, auditoriums, performing arts centers, places of worship and so on. The tweeter, with a separate subwoofer (Bose? MB12 or MB24 bass array) composed the group use, or used directly for language sound reinforcement. Bose V2 IF components into two 4.5-inch unit extended frequency range, with a smaller distortion and improved frequency response. Compared with ordinary 8-inch or 12-inch unit, can provide a smoother, more natural sound performance language. LT 9702 WR speaker Bose V2 is equipped with two intermediate frequency components. Large Bose waveguide provides an effective 90 ° x 70 ° dispersion angle control (levels can be as low as 250Hz multimedia reception hall meeting sound vertically down to 500Hz). The sound from the speaker to minimize the overlap between the international lecture hall acoustics, reduce comb filtering interference and improve speech intelligibility. Compliance with IEC 529 IPX5 rating can be used indoors or outdoors environment. ? Cover angle control technology: Bose Panaray covering angles LT series long-stroke speaker fairly tight range in the coverage angle of the speaker, the sound frequency response and sound pressure is very uniform; when more than cover the angular range, its sound Pressure decay is almost zero.
