Detailed Description Zone 4P
Zone 4P combines source management and amplification for four configurable audio zones. Its four integrated amplifier channels each deliver 100 W into 4 Ω or 8 Ω. This brings the controller, loudspeaker processing and amplification together for small to medium commercial systems.
Four stereo line inputs, two microphone inputs and two HDMI inputs provide connections for music, announcements and TV sound. Line input 1 has an S/PDIF option, while the microphone inputs supply 48 V phantom power. Four line outputs also allow additional amplifiers to be connected where the installation requires them.
Paired amplifier channels can operate in bridge mode at 200 W into an 8 Ω minimum load or a 70 V line. WebApp configures routing, loudspeaker presets and timed events, while ZonePad panels give staff access to everyday controls at the point of use. Paging and alarm-override inputs complete the system connections.
