Professional Sound Solution for Lecture Hall of the Indoor Stadium

The lecture hall in the stadium is also called the multifunctional lecture hall which can accommodate more than 300 people, with an area of 390㎡, about 28m in length, about 14m in width, and 4.3m in height. And the stage is about 9m in length and 6m in width. The lecture hall is mainly used for important conferences, various lectures, art performances, academic reports, and other important activities of the stadium. Due to the high frequency of use of the lecture hall, there are certain requirements for speaker quality and system functions.

The sound reinforcement system is mainly composed of speakers, power amplifiers, mixers, microphones, sound sources, video matrix system, and other equipment, which can realize simple meetings, lectures, special reports, etc.
D5821, D5824, and D5823 can be used as the audio source inputs, based on the customer's needs for speeches, special symposiums, and work reports.
MG16, D6573, D6643H, and D6642H can be used as professional audio processing equipment, making the sound clear without distortion and feedback howling.
In this system, we arrange two series of array speakers LA1420/the 1420S on both sides of the stage for full sound pressure, uniform sound field, and accurate sound image positioning on the scene; and six 350W full-range professional speakers D6565 for auxiliary sound reinforcement on both sides of the seats, making the live music clear with a better performance.

Professional Sound System Design

The array speakers integrate professional speakers, power amplifiers, and digital signal processing units. The digital signal processing unit can manage and optimize performance, as well as protect the power amplifier and sound reinforcement unit. And the unique correction technology can enhance the accuracy of sound expression and reduce on-site commissioning work. The array speaker system can transmit line-level signals, with low line loss and better sound quality.

Applications

With low noise, high intelligibility and durability, the speakers on both sides of the stage can work well without distortion even in a high-power working environment, for creating a stereo original sound in every corner of the lecture hall.

As the multifunctional conference system solution provided by DSPPA for the lecture hall has powerful functions and easy-to-understand system operation, it can effectively guarantee the daily operation of various meetings and activities in the lecture hall.
