Ahuja APZ-502CU Paging Selector Control Unit – 10-Zone Paging Controller for Professional PA Systems
In large buildings, public spaces, or campuses, delivering announcements without interrupting background music everywhere is crucial. The Ahuja APZ-502CU Paging Selector Control Unit offers precise, zone-wise control over paging and background music (BGM). Whether you’re running a school, hospital, or corporate facility, this unit provides a smart, scalable solution for your PA system needs.
Key Features:
10-Zone Smart Paging Controller with Expandable Architecture
The APZ-502CU is designed for flexible zone management. Each unit supports 10 zones, and you can cascade up to 30 units, making it a powerful solution for up to 300 individual paging zones.
Seamless Integration with APZ-501RM Remote Paging Microphone
This controller seamlessly connects with the Ahuja APZ-501RM, enabling paging from multiple remote locations. Remote paging is effective and synchronized with your centralized system, ensuring consistent zone-based communication.
Priority Zonal Paging with Local Mic Override
Need to override remote paging? The APZ-502CU includes provisions for local microphone input, enabling priority announcements. This is critical in emergency scenarios where real-time control is essential.
Dual Amplifier Inputs for Music & Paging
It features two amplifier channels—one for background music (BGM) and one for paging. This ensures music is only muted in zones receiving announcements, maintaining a pleasant atmosphere elsewhere.
Zone Status Indicators for Real-Time Monitoring
Each zone includes a dual-color LED indicator showing whether it’s playing music or being paged—so operators can monitor system status at a glance.
