Other electronic devices used on the stage, such as lighting consoles, audio equipment, wireless microphone receivers, etc., will also generate electromagnetic interference to varying degrees. Therefore, they need to be kept at a distance of at least 2 meters from the 4-way stage hoist controller. In particular, the dimmer in the lighting console will generate a large amount of harmonic interference during operation. If it is too close to the 4-way stage hoist controller, it may cause distortion of the controller's control signals. For wireless devices, their antennas should be avoided from facing the hoist controller to reduce the interference of radio waves on the controller.

In the equipment debugging stage, in addition to conducting routine tests on the signal transmission of the controller, the operating state under the complex electromagnetic environment of the stage should also be simulated. A spectrum analyzer can be used to detect the electromagnetic interference intensity around the controller. If the interference signal exceeds the specified threshold, electromagnetic filters or isolation transformers should be added in a timely manner. The electromagnetic filter should be installed at the power input end of the controller to filter out high-frequency interference in the power supply; the isolation transformer can be used to isolate the electromagnetic coupling between the controller and other equipment, thereby improving the anti-interference ability of the 4-way stage hoist controller.
