Figure 1.1
The Plena Mixer Amplifier is a mono amplifier for mixing up to 4 microphone signals and (background) music signals. You can adjust the volume of each input separately in order to obtain the correct mix and control the mixed output via the master volume and tone controls. Microphone input 1 can have priority with an optional chime signal, muting other sources. The power amplifier has a direct output for mixed signals and priority announcements, but additionally a priority controlled output relay routes the output to loudspeaker zones that should receive only priority announcements or no priority announcements at all.
