When designing Overhead Loudspeaker Paging Systems, the need many times arises for multiple inputs to an Amplifier. Additional equipment is needed.
Examples are alerting tones, fire alarms, weather alert tones, telephone ring tones, etc.
To accomplish multiple inputs, you can use a Mixer Amplifier or stand alone mixer to feed multiple signals into a single input amplifier. We often recommend Pro-Matrix Mixers and Amplifiers.
