Public broadcasting transmission line:

Although the transmission line is simple, it has different requirements depending on the system and transmission method. For auditoriums, theaters, etc., due to the short distance between the power amplifier and the speakers, 4~16Ω output ports can be used for output, and the transmission line requires a dedicated speaker cable; for the public address system, due to the wide service area and long distance, in order to reduce the transmission line For the loss caused by high-voltage transmission, a multi-strand sheathed wire with better insulation strength should be used.

Public address speaker system:

The loudspeaker system needs to match the entire broadcasting system, and the choice of its location should be realistic. Auditoriums, theaters, and dance halls have high requirements for timbre and sound quality, and speakers generally use high-power speakers; while public address systems, which require less timbre, can choose ceiling speakers, wall-mounted speakers, outdoor sound columns, etc. Lawn speakers, garden speakers, outdoor horns, etc.
