There are 12 overhead speakers on the ceiling of the banquet hall, of which 8 are facing the indoor area and 4 are facing the outdoor area, and the sound field is evenly distributed. In small performances or exhibitions, mobile devices can be installed to enhance the demonstration effect.

Equipped with two power amplifiers, the driving mode is constant resistance mode. One drives eight overhead speakers in the nursing room, and the other drives four speakers outside the nursing room. The simulated sound field analysis can be divided into two situations: closed banquet hall and open banquet hall. When the partition is open, eight speakers provide indoor sound reinforcement, and the other four speakers installed indoors are responsible for providing outdoor sound reinforcement for the dining table area. After the partition is closed, only eight speakers provide sound reinforcement for the room, and the other four speakers are turned off.

(1) Sound field simulation of closed ballroom,

(2) Sound field simulation of the open banquet hall (considering the terrace),

Including multi-functional banquet hall sound system, ceiling with 8 overhead speakers, evenly distributed, which can meet the requirements of small banquets and general meetings. When there are large banquets, important meetings and entertainment needs, mobile devices can be installed to enhance the demonstration effect.
