Xunkong Participated in Creating A Multifunctional Auditorium for A School in Sichuan

Xunkong has participated in creating a multifunctional auditorium for a school in Sichuan, which is successfully checked and accepted. The project has won unanimous praise from the clients.

Xunkong has participated in the whole process of the project, including the preliminary scheme design, the decoration and construction, product supply and engineering commissioning. The whole project is composed of different solutions including LED large-screen display system, stage lighting system, audio and video signal system, professional sound amplification and conference speech system, decoration and wiring system.

The design sketch of the project:

The large screen of the project makes use of LED for display system. With the length and width over 30 meters, the venue is very large. The large screen resolution is designed to combine a main screen and auxiliary screens. In addition, on the top of the large screen, a LED striped screen is equipped to display messages and other information.

The Main screen which is 12 meters wide and 4.8 meters high is placed in the center of the stage. In addition, two pieces of auxiliary screens that are respectively 4 meters wide and 2.5 meters high are installed on the both sides of the stage. As display screen system has ultra wide angle of view, there is no dead angle and no color cast. And the image can be displayed seamlessly, providing the auditorium with a high-definition, high brightness and perfect display system.

Since the auditorium is designed for multi-functional use, the design configuration and layout of the overall lighting system should meet the needs of all sorts of artistic performance. The whole stage should be laid out scientifically and reasonably. Stage lighting is divided into the inside area and outside area, which are equipped with basic lights that can be flexibly adjusted to meet the needs of performance and other functions. Therefore, the professional LED ceiling spotlight system is equipped, supported by multi-function PAR lamps, professional computer beam lights, follow spot, mist blower, fogger machine, digital silicon dimmer, switch unit , signal amplifier, professional lamp controller and other equipment. The main and auxiliary illumination interacted and cooperated to create different atmospheres for the auditorium, designed for all kinds of entertainment and purposes.

Lighting effect commissioning:

The sound reinforcement system of the auditorium takes the national sound reinforcement hall level (Standard L1) for reference, which is mainly composed of speakers, power amplifier, audio processing equipment, digital mixer console, microphones, audio source and other equipment.

Coverage angle plan of speakers:

In order to achieve higher sound pressure level and stronger directivity, 8 linear array speakers (L-8) are designed and installed as the main sound reinforcement speakers, and 2 ultra-low speakers (l-15B) are mounted on both sides of the stage, next to the two auxiliary LED screens. The sound amplifying system adopts the best stereo sound reinforcement way with left and right sound channels, which can effectively reduce the distortion of sound image, offering better auditory effect to the audience. 

Since the auditorium is more than 30 meters long, the back row area is not completely covered in the sound coverage of the main speakers. In order to improve the whole acoustic field uniformity  and audio-visual effect at the same time, 4 12-inch all frequency speakers (E-12L) are used at the back of the auditorium on both sides as auxiliary speakers, and 4 E-12L speakers are embedded for hidden installation along the stage below for sound reinforcement of the front area of the audience. In addition, the stage is equipped with 4 echo speakers (F-12) for performers to make a better performance in reality.

Sound Field Coverage Diagram: 

According to the professional sound field analysis and measurement by EASE, the maximum sound pressure level of the auditorium is up to 106dB, and the balanced sound pressure level is stable at 101db-103db, which meets and exceeds the requirements of the design for the sound reinforcement.

It is particularly important choose a set of high-performance, high-quality, leading-technology and cost-effective speaking equipment. Based on this concept, Xunkong offers the auditorium a set of time-keeping conference system which is formed of the leading-technology conference units (SV- MT318A/B) that have OLED displays, energy conservation and environmental protection, and timing and the countdown function. This conference system is very convenient for the the participants to control the speaking time.

Besides, it is easy for management personnel to manage and control various devices and signals in the auditorium through a wireless touch screen or a tablet PC. Xunkong adopts the control host D1008 to control the lighting, volume, electric curtain, air conditioning, large screen image display, etc. and other devices including power supply controller, dimmers, screen processor, seamless matrix switcher, etc., which makes all A/V signals and equipment controlled intensively and gets the control system to be expanded and upgraded in the future.
