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 alarm, weather alert tones, telephone ring tone, and etc. To accomplish this you can use a Mixer Amplifier or stand alone mixer to feed multiple signals into a single input amplifier.
