Specially designed for collecting external analog audio signals for IP network broadcasting systems, it can encode analog audio into digital audio and transmit it to designated area terminals for playback through the network.

Standard 19 inch rack design, black aluminum oxide brushed panel, sturdy pull-out, professional mechanical assembly process, machine appearance is very high-end

Industrial grade 4.3-inch color screen, which can clearly display most dot matrix patterns and machine working status; Equipped with an infrared remote control, it can play/pause any content in the on-demand server program library, with flexible and simple operation.

The device is designed using embedded computer technology and DSP audio processing technology.

Built in 1 network hardware audio encoding module, supporting TCP/IP, UDP, IGMP (multicast) protocols, realizing networked transmission of 16 bit CD sound quality audio signals.

3-channel AUX and 1-channel MIC input interface, with independent volume and high/low frequency adjustment potentiometer control, supporting local paging function when disconnected from the network.

1-channel EMC input interface, input emergency alarm voice signal as direct, with the highest priority

2-channel audio signal auxiliary output interface, expandable external power amplifier, standard lotus socket interface, easy wiring connection

Built in 3-channel intelligent power management, automatically turns on the power during music collection or calling, supports IP software programming pre power on function

Built in priority setting: EMC is given the highest priority, while MIC takes priority over AUX music signals.

Support mute intensity preset reduction function, support background accompaniment preset function; Support status light display, including level indicator light, protection indicator light, standby indicator light, etc.

Equipped with USB playback function and connected to a USB flash drive. Can remotely play any song and play the previous, next, pause, stop and other functions (or select panel button operation), locally play or push to any terminal

Support scheduled broadcasting tasks and temporary broadcasting tasks, and the priority level of broadcasting tasks can be set by the server.

Supports three playback modes: "Normal playback", "Intermediate playback", and "Advanced playback". "Normal playback" can achieve extremely low latency network audio capture effects, "Intermediate playback" can achieve low latency general sound quality network capture effects, and "Advanced playback" can achieve extremely low distortion rate network audio capture effects.

Supports routers, switches, bridge gateways Modem、Internet、2G、3G、4G、 Any network structure such as multicast, unicast, etc.

Support remote firmware upgrades for broadcast systems on terminals without the need for local upgrades, reducing the workload of maintenance personnel.
