Beijing Ditan Gymnasium - Boxing Training Center
Beijing Ditan Gymnasium covers an area of 11.4 thousand square meters, construction area of 13.6 thousand square meters, the venue size 44M × 24M, clear height 19.5M, have a fixed seating 2199, the platform front row has 14 seats. As Beijing in August 2008 a world-famous sports venues will be boxing training, in order to better serve this event, to serve the people in sports, at the end of 2007 a systematic transformation and equipment renewal.
The boxing training center as an integrated stadium sporting events in the meet at the same time, but also a variety of small and medium sized performing both functions. The transformation of the sound system include: the main stadium venue sound reinforcement system and a training center, second floor PA system. Advanced Communication Equipment (International) Limited, as the sound system integrators, beginning from the design will be built according to the basic sound of the stadium features and usage requirements, and made reference to several domestic and international new construction, renovation design of sports venues and experience the advantages of , in line with the reliability, stability, scientific, economic, practical design purpose, design a set of versatility, versatility and scalability as one of the PA system.
Sports Main venue sound reinforcement system design specification
Sports Main venue sound reinforcement sound reinforcement system design, including the venue's sound reinforcement system, auditorium sound reinforcement system, the podium listening systems, sound reinforcement control room monitoring systems, mobile sound reinforcement systems can be used independently of the subsystem.
Distributed sound reinforcement using the venue sound reinforcement-style layout, centralized distribution of the auditorium-style arrangement of reinforcement, the podium with the flow of sound reinforcement approach. Sound reinforcement system equipment can be divided into six parts: PA equipment, processing equipment, power amplifier equipment, mixing devices, peripheral devices and the signal processor and audio pickup device. The six formed part of the co-ordinated to ensure that the results are satisfactory when used to manipulate easily, reducing opportunities for error, and can set up in a very short period of time will be able to meet any changing needs.
The main competition field sound reinforcement system selected the United States JBL AE Series loudspeakers, AE Series loudspeaker is designed for large-scale sports venues and high-end theater designed. On the special train PT? Waveguide technology, two-way design, low-frequency limit can be 45Hz, so that to maximize the efficiency of long-distance voice transmission, the maximum sound pressure level alone reached more than 133dB, power 1000W, directional accurate, big power. The strong sales of special lock-bit systems, so that hoisting more convenient and more secure. Follow the 7:1 safety factor, box angle adjustment can be accurately and easily adjusted.
In addition, we have designed two JBL SRX series of two-way loudspeaker dedicated to take care of the VIP podium position, using an external passive crossover mode driver, to ensure the sound quality of music sound reinforcement requirements, and has a higher resolution.
All loudspeakers are equipped with the power to match the U.S. Crown CROWN CTS series of power amplifiers. Crown amplifier with amazing sound quality and strong power, CTS family is an example of today's power amplifier design. Unique damping is greater than 1000, so incomparably beautiful sounding bass; than 13V/ms conversion rate, so clear, bright treble anomaly; ultra-low phase distortion, so that a more realistic sound natural; ODEP (Output device simulation Protection ) patented technology to solve the power amplifier overload shutdown problems and improve the efficiency of the output circuit; advanced IOC indicator to ensure that no distortion, high-performance power amplifier output; second low-frequency and DC voltage output protection, and ultra-high frequency and radio frequency interference protection, can make speaker are not compromised; ground isolation switch to avoid the system signal with the power to cross-coupling caused by the exchange of hum. CTS series of metal packaging output devices, using advanced equipment and testing of each device's power curve and the peak power handling capability, through the use of screening and after pairing. With low distortion, high signal to noise ratio, low operating noise, and so on.
System, audio processing system arranged throughout the system, we should be able to deal effectively with the uniformity of sound field and sound, we have adopted a unit of Harman Group, BSS Audio intelligent network control processor. Sound reinforcement system in use between the mixer and the amplifier British BSS SoundWeb 3088 digital sound System. BSS launched in 3088 the network digital audio processor, each have eight analog input and output, set the gain, balance, pressure limit switch, sub-frequency filtering and other functions into one, composed of simple, flexible and convenient adjustment through the network to send digital audio signals, eliminating the past, various forms of traditional analog systems where the use of a complex variety of processing equipment. BSS SOUNDWEB system can be real-time control, testing each channel output level can also be off-line work alone, in normal use, the controller can not rely on external control computer and work independently. The device is a 24-bit, 48 kHz sampling, dynamic range up to 144dB, so that the sound reduction phase accuracy, low distortion, good transparency and transient response. Debugging the results of all the different sound field settings are the file form your computer, it can be modified at any time and switch.
In addition, the fire emergency broadcast signal can be directly into the Soundweb systems, by setting, if there is an emergency broadcast signal incoming fire (for example, higher than the signal-10dbu arrival), the system will automatically switch to an emergency broadcast signal in order to protect the people lives.
Mixer is a sound reinforcement system of central control equipment, good or bad quality of sound reinforcement system has a direct impact. According to actual needs, we use English SoundCraft GB8 Series 32 input mixer. This mixer has been used on many occasions, its addition to having a general sound reinforcement mixer owned by the basic functions, the function of its eight marshalling process can control will simplify operations, reduce error chances, but their gain would be able to put input of the signal amplification of 70 dB, while the equivalent input noise microphone (Microphone Equivalent Input Noise) in the 22Hz to 22000Hz, can less than -127.5 dB. In addition, each input channel has two input interface may be independent selection lines (high), or microphone level (low), while the 180-degree phase-change function, which foreign performing groups is particularly important because the phase of each country standards are may be different, when this problem occurs, simply press the button in question-channel phase can immediately be 180 degrees phase shift, the operation is very convenient.
5. Neighboring processors and audio equipment
All sources are chosen TASCAM professional broadcast grade equipment, CD machine, MD machines, as well as pairs of Kaka plane, and designed a platform Lexicon effects, 2 DBX 2231 graphic EQs can meet a variety of application needs. TASCAM professional broadcast equipment is world-class radio and television stations widely used in demonstration of its stability.
6. Signal equipments
For wireless microphone option, we are mainly based on the following three considerations: First, a stable and reliable carrier frequency transmitter and receiver with tracking capabilities, to achieve reliable reception; two wireless microphone must be used with the performance requirements of modern art; third, the selected operating frequency must be consistent with national radio frequencies using the appropriate requirements in order to frequency interference from the outside world. SHURE wireless microphone system for sound reinforcement pickup known for, and in some major events in both the domestic use SHURE products with high reliability. Therefore, we use SHURE wireless microphone as the main product. Wireless Microphone System SHURE wireless microphone product configuration in order to transmit / receive equipment based on actual demand according to performance and then choose different brands of pickup.
