Application of Speaker Arrays Stage Hoist Controllers:
Application: To achieve optimal acoustic performance or for aesthetic concealment, main line array speakers, subwoofers, or distributed column speakers are often designed to be raised and lowered.
Controller Function: Adjusts the height and angle of the speakers (if equipped with an angling mechanism) based on the event type (lecture, concert, banquet). Safe, smooth, and quiet operation is critical to avoid generating mechanical noise that interferes with sound quality.
Controller Type: speaker arrays Stage hoist controllers can be single-point or group-controlled (for synchronizing multiple speakers). They typically require low operating noise and smooth start-stop transitions.
Lighting Truss / Fixture Hoisting:
Application: Truss systems suspending front lights, profile spots, effects lights, followspots, etc., need to be raised and lowered to facilitate installation, maintenance, and adjustment of lighting height and angle based on event requirements.
Controller Function: Precisely adjusts the height of the lighting fixtures. For complex truss structures, this may involve multi-point synchronized hoisting or positioning. Fixtures are often heavy and high-value, making safety and reliability the primary concern.
Controller Type: Group control systems are predominant. They require high synchronization accuracy, overload protection, stall protection, and other safety features. Positioning functionality is particularly important.
