Features:

Designed with embedded PC technology and DSP audio processing technology: Built in embedded network voice decoding module to achieve synchronous reception and decoding of network audio streams; Using high-speed industrial grade ARM chips, the startup time reaches millisecond level; Improve the stability of device usage

Built in embedded network voice decoding module

Having an independent IP address, it can receive personalized scheduled playback programs from the server separately

High quality digital audio transmission, noise free, with CD level sound quality (adaptive audio file bit rate of 32-320kbps)

Support volume and balance adjustment: The device has full digital high, low, and master volume adjustment, making the adjustment clearer, more flexible, and accurate

Equipped with intelligent power management function, the device uses a built-in CPU to determine the operating status of the amplifier. When there is no working state, the amplifier automatically enters a sleep state with a standby power of ≤ 0.2W. When there is a playback task, the amplifier automatically starts up

Equipped with remote volume adjustment function, the terminal automatically adjusts the volume to the default state set by the system when starting and playing tasks automatically. The default values for automatic volume adjustment can be set as background music volume, emergency broadcast volume, fire broadcast volume, etc

Receive broadcast programs from servers through the network, including microphone paging, automatic forced insertion of fire alarms, telephone paging, etc

One line multi use: make full use of existing network resources, avoid redundant installation of lines, compatible with TCP/IP network protocol, can be hung anywhere reached by Ethernet network, truly realizing the integration of multiple networks such as broadcasting, computer, monitoring network, etc

The decoding terminal is equipped with an IP address reset switch, which can restore the factory settings
