Wuhan professional audio price, Wuhan Jiuhua video (certified), audio video provided by Wuhan Engineering Co., Ltd. Jiuhua. Jiuhua Video Engineering Co., Ltd., Wuhan (www.jowa-tech.com) is specialized in the "network products, multimedia products, audio equipment, smart home product design and installation," the enterprise, the company of "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Lo. Sound reinforcement system mainly product information and related parameters: JBL JRX112M FOH sound stereo Features: JR × 112M stereo is a compact and low profile design of the sound, so do not take up too much space or block the vision of the audience hall. The most important stage is the speaker midrange clarity. We pay special attention to maximize the harsh tenor optimization features. Use JR × 112M high sound pressure sensitivity and moderate drive amplifier can produce powerful enough sound pressure level. JR × 112M includes JBL's dual-angle pole socket, the front room, after the part of the audience can get the same sound pressure level. Technical parameters: Frequency range (-10dB) 1 60Hz-16kHz frequency response (± 3dB) 1 70Hz-12kHz sound pressure sensitivity (1W / 1m) 99dB rated power and impedance 2 250W / 8Ω peak power (W) 2 1000W Recommended amplifier ( W) 250W-500W / 8Ω maximum SPL (1M) 129dB directivity characteristics (HXV) 90 ° x 50 ° 1.8kHz crossover frequency volume (H x W x L) 572x394x318mm Weight (kg) 19.5 low frequency drive (JBL) M112 -8 high frequency drive (JBL) Scientific Design 24121 "sound reinforcement systems: performance results with good fullness, you can make the sound full, rich, melodious music active in the electro-acoustic system, only through the use of sound. Peripherals efficient sound signal processing and a reasonable selection of speakers of these measures, the fullness of the sound to be able to meet the requirements. sound reinforcement system acoustic characteristics of computer-aided design is the use of modern technology in an ideal way of Wuhan Engineering JBL audio Where there is high-precision, high efficiency, more importantly, there is no need to wait until the end of the installation will be able to know the results of the engineering design. acoustic characteristics of computer design system has a very good credibility and accuracy of Wuhan sound engineering, installation, enter the hall built in sound When the data is accurate enough Wuhan professional sound price, which is calculated with the final electro-acoustic data comparing the measured results, the error can be controlled within decibels. to engineering design and installation, this is enough, but it also has a very good design installation and commissioning guidance, which has been well validated in previous engineering design. CAD computer system uses acoustic design calculations hall, gymnasium (field), the acoustic characteristics of multi-purpose hall, lecture hall sound system, it means, no need to wait until after the system installation, commissioning and measurement is completed, will be able to know the results of their design and installation. In other words, according to the audio system and design calculations given in this design has clearly see that the system is expected to sound acoustic characteristics of the PA system.
