1. Product Introduction

The COMTOM CT-NB8208 paging microphone console is a high-performance PA system paging station designed for remote audio control and multi-zone broadcasting. Equipped with a 3.0-inch color display and intuitive interface, it allows operators to perform zone selection, program playback, and emergency announcements directly from the console. It is widely used in school PA systems, factory paging systems, commercial building broadcast systems, and IP-based public address networks, where centralized and remote communication is required.

2. Core Advantages

The CT-NB8208 integrates a built-in MP3 player with ≥2GB storage and SD card expansion, enabling local audio playback and chime tone generation. It supports AUX input for external audio sources and transmits microphone, MP3, and AUX signals over long distances exceeding 500 meters. Using RS485 communication with FIFO data architecture, the system supports stable multi-device cascading with up to 16 paging consoles in a daisy-chain configuration. This makes it ideal for large-scale multi-zone PA system control environments requiring distributed operation points.

3. Application Scenarios

This paging microphone console is widely deployed in environments requiring flexible zone-based communication. In schools, it is used for classroom announcements, bell control, and emergency evacuation paging. In factories, it enables workshop-level communication and safety alerts across production zones. In commercial buildings and shopping malls, it supports background music control and promotional broadcasting. It is also used in transportation hubs, logistics centers, and government facilities where operators need direct control of multi-zone public address systems.

4. System Compatibility

The CT-NB8208 is fully compatible with both IP PA systems and 70V/100V constant voltage PA systems, making it suitable for hybrid system integration. It connects to the main PA host via RJ45 network cable for remote zone switching, program selection, and power control. It supports full remote operation of the central PA system, allowing operators to manage up to 16 broadcast zones (CH1–CH16) with individual or group control. Audio input includes MIC, AUX (10kΩ, 350mV), and line output (10V balanced), ensuring compatibility with professional public address system architectures.
