The world's first Meyer Sound exhibition hall ceiling active system landing on Silicon Valley​

The McEnery Conference Center in San Jose, United States, recently completed a forward-looking Meyer Sound project, setting up the world's first Meyer Sound active showroom smallpox system, making the conference center officially jumped into the focus of the global conference of convention and Exhibition (MICE) frontiers.

Silicon Valley is a global innovation center. The local innovation spirit is not only limited to IT and Internet industry, but also to the innovative application of AV technology. As the largest conference and Exhibition Center in Silicon Valley, McEnery has been looking forward and focused on innovation and market leadership in the face of unusually complex and harsh demands and expectations from customers such as apple, Facebook and NVidia.

The core of the new sound reinforcement system is the application of a smallpox system that can be integrated into a delay compensated voice to line array system in real time. But in order to ensure that no matter where the stage location (zero) is located, this function can be achieved. The system requires not only linear, full bandwidth response, but also the independent delay of each speaker. More important, many of the future market leading companies will employ A-1 level engineers in different major activities, which must be tested and accepted by these engineers.

The first stage of the project is to remove the old ceiling with T type pole installed constant pressure system. The reverberation time of the exposed bucket ceiling was 7 seconds after the removal of the ceiling, but under the guidance of the acoustic consultant, the reverberation time was reduced to about 1 second after the extreme acoustic treatment of the intermediate frequency band RT60.

A total of 226 independently controlled speakers and 60 hyper bass speakers are deployed in the solution. The system provides flexible and comprehensive bandwidth response in independent operation, and can also be used as a delay system when deploying a temporary line array in a large conference.

The core technology of the integrated system uses the IntelligentDC of Meyer Sound, which has functional and comprehensive flexibility. It combines the sound quality of the active speaker and the advantage of the installation of the low voltage system. Each compact and lightweight loudspeaker receives discrete dedicated line level audio signals and 48V DC power from a remote rack MPS-488HP power unit. The technology can also monitor all the speakers in the system, which not only allows each speaker to delay, balance or mute, but also allows the technical personnel to operate freely on the mobile control equipment.

The main speaker of the system is UPJunior-XP, a compact 26 minute compact two frequency loudspeaker, which accurately provides 80 degree 50 degree coverage. In order to extend the frequency response of the flatness system to the minimum scale of eight degrees, a total of 60 Amie-Sub hyper bass speakers are added to the heart configuration, which is configured to be 20 three sound box combinations; such a directional control of the heart configuration is very important to control the bass rebound of the bucket shaped ceiling, especially effective.

After the transformation, the audio system and available space of the San Jose Conference Center are more flexible and flexible, and suitable for a wider customer base. Especially in meetings, business time is very important, sometimes in the setting and adjustment delay of the audio system, it will even consume the time of the whole day, which often directly affects the other aspects including the set up time arrangement.
