Mic inputs have 3-band tone control, priority and talkover, so announcements lower the music automatically, and 48 V DC phantom power supports condenser mics. A Bluetooth 4.2 receiver and a front 3.5 mm jack make it easy for staff to play music from a phone. A priority mute contact lets a fire alarm silence the system. Master output has 2-band tone control and an LED level meter; each zone has its own source selection and volume.
