Conference Room Speaker System, Key Point One

The most important requirement of conference room speaker system is that it has enough sound pressure level, clear voice, good sound quality, good voice performance, uniform sound field and high transmission gain (not easy to scream).

To meet this requirement, the layout point, quantity and power of the speaker should be determined first. The first key point is the arrangement of speakers.

Speaking of the arrangement of speakers, many people say that the main speaker should be added to the sound box. In fact, conference rooms are different from theatres, live performances and other professional audio occasions, for these performance venues, audio-visual positioning is very important. They want the unity of sound and image to make the audience feel that the sound comes from the stage.

For the construction of conference room speaker system, the most important task is to let the audience hear and hear the speaker's speech, rather than care about where the voice comes from. It is not easy to realize the uniformity of sound field by adding a sound box to the main speaker. The uniform arrangement of wall-mounted speakers and ceiling horns can obviously improve the uniformity, clarity and sound transmission gain of the whole conference room. Therefore, the first key point of conference room speaker system construction is decentralized multi-point layout.

For decentralized multi-point arrangement, wall-mounted speakers and ceiling horns are usually used. By doing so, the sound field can be more uniform and the transmission gain can be greatly improved (the scream can be reduced). Multichannel digital power amplifier is the best choice for power amplifier, one power amplifier for a speaker or smallpox horn. Now the conference room control center computer room, they have small space, but more equipment, if the traditional AB class two-channel power amplifier is used, they have a high heat, fan noise, power amplifier occupies a large cabinet space. If multi-channel digital power amplifier is selected, this problem can be solved very well.
