1, the auditorium: The main loudspeaker system serving the audience includes the following elements: (60 ⅹ 40) four high-tone tubes, (90 ⅹ 40) tweeters and two high-frequency horns And low-frequency speakers four (a solid lifting in the audio corridor, will not produce mechanical noise due to vibration), radiation field, the balcony and the auditorium audience stage; stage mouth left and right sides of the wall with a three-frequency Box, radiation in the auditorium in the former area, and the top of the mouth of the audio corridor speaker audio and video down, to ensure that the site more natural audio and video sensory; pick Taiwan set up under the six full-frequency engineering series with audio delay As the platform under the complement of sound; serve stage performers stage back to send the system consists of four two-way back to send sound composition; both sides of the platform at the same time set up two full-frequency box for the meeting when the podium Seat heard; hall of the technical space, such as the dressing room, light control room and so set up a monitoring system. The sound spots are arranged on the walls of the stage, on the stage floor, on the inner walls of the orchestra, on the auditorium (on the external walls of the orchestra), on both sides of the auditorium, on the second floor. The need for more than 80 microphone points through the machine room by the user the flexibility of the plug hole to transfer to the tuning channel. Peripheral equipment, the system set to serve the audience of the digital reverb; configure the distribution amplifier for the PA signal transmission and external signal exchange, to meet the needs of the broadcast situation; channel set feedback suppressor; system to add real-time spectrum analysis Instrument, the measurement microphone is fixed in the pick platform for users to monitor, adjust. |
