Audio is often used in banquet halls, such as weddings, birthday banquets, thank-you banquets and annual meetings. The main amplifier and echo box should be used on the stage, and the sound should be supplemented in the backcourt to meet different customer needs. It is also necessary to consider whether the receiving range and signal transmission of the wireless microphone are good enough. It is recommended to use Rambo RB audio equipment as the whole audio system, with good sound quality and product quality. Our hotel uses this brand, and many wedding ceremonies say the sound is good.
