Features:

Standard rack mounted, 2U height; Advanced aluminum panel, using advanced polishing technology

Using a fixed static IP address, the address will not be lost when the network changes, ensuring stable operation

Designed using embedded PC technology and DSP audio processing technology; Built in embedded network voice encoding and decoding module, completing synchronous reception and encoding/decoding of network audio streams; Using high-speed industrial grade ARM chips, the startup time reaches millisecond level

An interface with one or four RJ45 download addresses, which can adapt to different network locations and modify addresses

Transmitting multiple sets of audio program content over the network

Single device has 1 audio matrix switching function

One or four LINE/MIC signal inputs, one or four independent network TCP/IP encoding functions; Independent volume adjustment; High quality digital audio transmission, noise free, capable of one-way calling

Sound quality reaches CD level (adaptive audio file bit rate of 32-320kbps)

The system configuration is complete, and the corresponding area broadcast terminal can be directly started by pressing the button 1 on the operation panel

Super strong cross gateway and cross routing capabilities, accessible wherever there is an Ethernet port

Equipped with remote upgrade function, product program updates do not require on-site upgrades and can be updated remotely through the network, which is convenient and fast

Multiple machines can be stacked, and multiple devices can be installed in one system without any quantity limit

The back of the machine is equipped with an IP address reset switch, which can restore the factory settings after resetting
