Description:

Installed in weak power room or sub-control room of each broadcast management area, it has built-in high-fidelity power amplifier, suitable for the halls, corridor, outdoor and other areas of the program broadcast and local radio.

Features:

• * Standard 19-inch rack design with a black anodized brushed aluminum panel, sturdy handles, and professional mechanical assembly craftsmanship, giving the machine a very high-end appearance.
• * Industrial-grade 3.4-inch LCD display that clearly shows most dot matrix patterns and the machine's working status; supports infrared functionality, allowing content from the on-demand server program library to be accessed with an infrared remote control and enabling flexible and simple playback/pause control.
• * With embedded computer and DSP audio processing technology.
• * Built-in 1-channel network hardware audio decoding module supports TCP/IP and UDP, achieving network transmission of 16-bit CD-quality audio signals.
• * Equipped with a high-fidelity professional digital amplifier, featuring a power output of 60W at constant voltage (100V).
• * 1-channel AUX line input and 1-channel microphone (MIC) input interface with independent volume and bass/treble adjustment potentiometers, supporting local paging function in case of network disconnection.
• * 1-channel EMC input interface, with emergency alarm voice signals passed through, having the highest priority.
• * 1-channel auxiliary audio signal output interface for connecting external power amplifiers, featuring standard RCA connectors, making wiring connections very convenient.
• * 1-channel three-wire audio control emergency override output interface, no need for power override.
• * Built-in intelligent power management; automatically cuts off amplifier power when there is no music or call, and automatically turns on the amplifier power when there is a signal, with support for IP software programming to pre-open the amplifier power.
• * Built-in 3-level priority settings:
• EMC has the highest priority.
• Network alarm signals take precedence over MIC, AUX, and network background music signals.
• MIC takes priority over AUX and network background music signals.
• AUX and network background music signals are at the same level with no priority.
• * Supports mute intensity preset reduction functionality and background accompaniment preset functionality; includes status lamp display, such as level indicator, protection indicator, standby indicator, etc.
• * Compatible with routers, switches, bridge gateways, Modems, Internet, 2G, 3G, 4G, and any network structure.
• * Digitized product with easy expansion, location-independent, no need to add equipment for data center management, designed for shared network and installation convenience.
• * Supports remote firmware upgrades for terminals through the broadcasting system, eliminating the need for local upgrades and reducing maintenance workload.
• * Features USB playback functionality with USB drive input; when paired with an infrared remote control, it can play any song along with previous/next tracks, pause, stop, etc. (or select panel button operation).
• * 1-channel short-circuit input that can be used to trigger preset voice prompts (or alarms) and can also be used to control access control linkage with short-circuit input signals.
• * Comes with a 1-channel 100V constant voltage power backup input interface, allowing for flexible configuration of one main with multiple backups, multiple mains with one backup, or multiple mains with multiple backups for a highly reliable public ringing system.
• * Built-in high-performance main/backup switching detection module, switching to backup power input within 0.3 seconds during network, power outages, or machine failures.
