The TX-PSD1 is the ideal choice in many applications where switching needs to be controlled from a constant-voltage amplified audio source. The module will trigger on any program material, with paging sources being the most common. The TX-PSD1 provides an open-collector SLAVE output to control other modules or equipment when a paging signal is detected.
