The balanced mic input has priority and 15 V phantom power, so announcements override background music from the RCA or 3.5 mm line input. A priority mute contact ties in a fire alarm. Speakers connect to a 4-pin terminal block with 4 Ω, 70V and 100V taps, and protection covers short circuits, overheating, overload and clipping.
