- * Built-in 240W high-efficiency digital power amplifier, integrated 2 power A + B independent dual-speaker loop zone output, each zone has independent LED indicator, independent output control buttons and volume adjustment.
- *4 audio balanced input interfaces for playing any audio source in the zones*Local emergency PTT microphone input and emergency voice can be configured by PC software to be played in specific zone.
- *Automatically detect the working status of each zone loop (fault, normal)*The 4-channel trigger input/output port can trigger the emergency voice preset by the PC software to the specified zone or the corresponding external power source to the corresponding event warning.*Support third-party emergency audio input (user-defined emergency audio source)*Integrated independent EVAC/ALERT voice information player.*The remote paging microphone / fireman microphone online interface can connect with remote paging microphone and firemanmicrophone, each paging station connection uses standard RJ-45 network port and standard CAT-5 network cable, voice transmission uses balanced transmission mode for long-distance transmission.*Controller online interface can be connected to the slave unit, it uses standard RJ-45 network port and standard CAT-5 network cable.*communication interface, supports visual interface operation based on Window platform, and the system status can be automatically synchronized.*Support DC24V battery backup power supply.*With power amplifier monitoring function.*Support PTT recording function, no external equipment required.*System fault, dry contact output for emergency status, dry contact input for emergency status reset*The zone output has three-wire and four-wire over-ridding adjustment functions.*With IP address reset function and impedance calibration function.*The master-slave unit is integrated, and the device can be used as a controller or a slave unit by setting code address, and the maximum of 19 slaves can be simultaneously online.*The system can extend the number of the zones by slave units, it support 40 zones maximum.Specifications:
