ZHC368M Emergency Broadcast Processor
1. Overview
The emergency plug-in processor has a built-in high-quality microphone preamplifier, a switchable phantom power supply and a digital FM modulator, and a U-disk jack to play MP3 audio signals. When you need to insert an emergency broadcast signal, just press the emergency broadcast button, and the emergency broadcast processor will immediately output the FM radio frequency signal to the RF input port of the near-end machine. At this time, all 16 FM channels will insert the emergency broadcast signal.
