Experienced technical personnel are aware, the debugging of large sound engineering sometimes than installing more cumbersome effort, installation and a drawing of what, the machine is new, at least not worried about any big problems. Maintenance and height is not the same, because the device may not at that time to maintenance technicians to install, so are not familiar with the line, even on the operating functions may not be familiar with, so the trouble is inevitable, need more rational analysis and detection of patience.B44service manual download site
The audio system we have maintained is generally divided into the following several:B44service manual download site
Is a common conference room, hall in the company such as places, these places sound generally not very large, equipped with basic speakers, amplifier, mixer, equalizer, effects, music playback source, wireless microphones and other basic equipment, usually have the rooms or dedicated console to the positioning of the device, at the far end of the circuit output is speaker wire, besides other devices are mostly concentrated in one place. This maintenance is concerned, the relative to facilitate some, at least the fault range is relatively easy to troubleshoot.B44service manual download site
The other is a large number of stage lighting systems. In the maintenance process of the sound stage we concluded that, in addition to the above small audio system with the characteristics of, large sound also has complex line, long distance transmission, operation control modes, equipment installation does not focus on the characteristics, such as a cinema hall stage, basic lighting system can divided into five to ten road lights to illuminate, the number of speakers are more, power amplifier is more, but not small power and detection to switch canonical order carefully, lest the artificial damage. In addition, this large stage tend to have a separate room to operate and play audio system, as well as separate controllable silicon box to control the lights, complex line between equipment, failure factors, inspection and maintenance are more difficult.
