500W IP Audio Power Amplifier – 8 Zones

High-Performance Amplifier for 7700 Series IP Audio Systems

The 500W IP Audio Power Amplifier from the 7700 Series is designed for reliable, 24/7 operation in multi-zone paging, public address, and background music systems. Perfect for schools, airports, shopping malls, sports venues, and public spaces, this amplifier provides superior audio quality and intelligent network integration, making it a powerful solution for clear communication across large environments.


Key Features:

? High-Fidelity 500W Output8 independent zones, delivering clear and powerful sound across various locations
? IP Network Audio Integration – Built-in TCP/IP, UDP, IGMP (multicast) support for 16-bit CD-quality audio transmission
? Advanced DSP ProcessingEmbedded DSP technology for optimized sound clarity and low latency audio delivery
? 19” Rack-Mount DesignProfessional black aluminum panel, with a 3.4” LCD display for status monitoring
? Multiple Inputs & Outputs:
    - 1 x AUX (Line) Input & 1 x MIC Input (Independent volume, treble, and bass control)
    - 1 x EMC Input (Highest priority for emergency audio signals)
    - 2 x RCA Audio Outputs (For additional amplifier connections)
? Intelligent Power ManagementAutomatic standby mode when there is no background music or paging signal, consuming less than 3W in standby
? Priority Control – Adjustable audio priority levels for:
    - EMC Signals (Highest priority)
    - Network Alarm Signals (Higher than MIC, AUX, and background music)
    - MIC Inputs (Higher than AUX and background music)
    - AUX and BGM (Equal priority)
? Energy Efficient – High-efficiency design for continuous, reliable operation


Ideal for:

Educational Institutions – Multi-zone paging, announcements, and background music for classrooms, lecture halls, and common areas
Retail & Commercial Spaces – Professional paging systems, in-store music, and public address
Corporate OfficesMulti-zone audio for conference rooms, lobbies, and offices
Airports & Transport HubsClear, efficient communication across multiple zones in busy terminals
Large Venues & Sports Arenas – Robust and scalable audio system for public announcements and background sound
