Detailed Description Zone 4
Zone 4 manages four independently configurable audio zones from one controller. Sources can be assigned to areas such as a bar, lobby, restaurant or shop floor, with source selection and volume adjusted for each area. Onboard DSP provides the processing and loudspeaker presets used to configure the system.
Four stereo line inputs, two microphone inputs and two HDMI inputs accommodate music, announcements and TV sound. Line input 1 also offers an S/PDIF option. The microphone inputs include 48 V phantom power, and dedicated connections support ZonePad panels, paging stations and alarm override.
WebApp runs inside Zone 4 and opens in a browser for installer setup and everyday control. Presets and timed routines recall changes during the day. Four line outputs feed external amplifiers, allowing the amplifier choice to match the loudspeaker load and output required in each zone.
