CT7512 Networked Playback Terminal – Product Description

Overview

The CT7512 Networked Playback Terminal is a high-performance, wall-mounted digital audio solution designed for professional public address and background music systems. Built on a fully digital architecture and leveraging the TCP/IP network protocol, this terminal functions as an intelligent signal processor that receives and plays audio content from a central control system. It is ideal for use in commercial environments such as schools, hospitals, shopping centers, hotels, and office buildings, where reliable, high-fidelity audio playback and emergency alerting are essential.

Engineered for both networked operation and local control, the CT7512 delivers seamless integration into large-scale audio systems while maintaining independent functionality for local playback and monitoring.

Key Features & Benefits

1. Fully Digital Signal Processing with TCP/IP Networking

• Based on the standard TCP/IP transmission protocol, enabling integration into existing network infrastructures.
• Acts as a fully digital analog-to-digital conversion signal processor, ensuring minimal signal loss and maximum audio fidelity.
• Centrally controlled by a main control system for coordinated playback of background music, emergency paging, and alarm signals across multiple zones.

2. Integrated 2×25W Digital Power Amplifier

• Built-in high-efficiency digital power amplifier (2×25W)capable of directly driving passive speakers—eliminating the need for external amplification in many installations.
• Designed with low power consumption settings, making it energy-efficient and suitable for 24/7 operation.
• Ideal for small to medium-sized rooms or zones requiring self-contained audio output.

3. Premium Design with Intelligent Display

• Features a high-end piano-lacquered front panel for a sleek, professional appearance.
• Equipped with a digital display that shows:
  • Real-time clock (RTC)
  • USB flash drive program playback serial number
• Provides users with instant visual feedback for scheduling and playback status.

4. High-Fidelity Audio Performance

• Powered by an industrial-grade chip and a fully digital design.
• Integrated DSP (Digital Signal Processing) audio chipenhances sound clarity, dynamic range, and noise reduction.
• Supports decoding of 16-bit digital audio streams at a maximum sampling rate of 48kHz.
• Delivers CD-quality, high-fidelity sound with a high voice transmission index (STI), ensuring clear speech intelligibility.

5. Advanced Real-Time Operating System

• Runs on an independently developed real-time operating system (RTOS).
• Ensures strong real-time performance and perfect synchronization of audio across multiple terminals—even when playing different programs simultaneously.
• Critical for applications requiring precise timing, such as emergency alerts or multi-zone paging.

6. Flexible Local Playback & Connectivity

• Includes an MP3 player with USB portfor local media playback—ideal for standalone operation or backup content.
• Comprehensive I/O Interfaces:
  • 1 × Auxiliary audio input (for external devices)
  • 1 × Auxiliary audio output (for daisy-chaining or recording)
  • 1 × Microphone input (supports local paging)
  • 1 × Short-circuit output (for triggering alarms or relays)
  • 1 × DC 24V output (powers external devices like sensors or relays)

7. Monitoring & Status Indication

• Supports on-site ambient sound monitoringvia microphone input.
• Enables Output Audio Monitoring for system diagnostics and quality control.
• LED Indicators clearly displays device working status and signal activity for quick troubleshooting.

8. User-Friendly Local Control

• Panel includes 6 shortcut keys for easy access to common functions such as play, pause, volume control, source selection, and emergency paging.
• Allows staff to operate the system efficiently without needing network access.

9. Network Configuration & Redundancy

• IP address can be set via web interface or management software.
• Supports domain name login, allowing connection to dynamic IP servers—no fixed public IP required on the server side.
• Features automatic failover between primary and backup servers:
  • If the primary server fails, the terminal automatically switches to the backup serverwithout manual intervention, ensuring uninterrupted service.

10. Compact & Mountable Design

• Dimensions: 238 × 190 × 52 mm (L × W × H)
• Wall-mountable with standardized hole spacing: 150 × 166 mm center distance
• Space-efficient and easy to install in electrical cabinets, corridors, or control rooms.
