SR-IPVTR is an IP Digital Network Rack Type Voice Terminal with paging,decoding,acquisiting and intelligent power management function.

The digital audio signal can be encoded into an analog signal and connected to a traditional power amplifier.

A native analog audio source can be real-time encoded into a digital audio signal, real-time acquisition and transmission to any other one, more or all of the terminals. 

The weak current room or equipment room installed in each broadcasting management area can be connected with the traditional power amplifier, which can be used for broadcasting programs and native broadcasting in the hall, corridor, outdoor and other areas.

Futures:

1.Standard rack design, using high-speed industrial chip, start faster and more stable.

2.4.3 inch big screen real-time display of program broadcast, timing broadcast, device operation, IP address, firmware version and other status information.

3.Using fixed static IP address, when the network changes, the address will not be lost and the work will be stable.

4.The embedded PC technology and DSP audio processing technology are used to design the embedded network voice coding module to complete the synchronous reception and coding and decoding of the network audio stream, so that the audio quality can reach the CD level.

5.Built-in 2G2GByte SSD, supports server remote management, remote upgrade firmware version, support limited broadband background download, media library files can turn on offline automatic playback function.

6.With USB interface, the audio file of local U disk can be played on demand. With programming pre-open power function, Power control key can manually turn on the power interface.

7.Paging function: one-way paging (1 key), group paging (4 keys), whole area paging (7 keys), two-way intercom (5 keys).

8.1 channel Line audio input, 1 channel MIC input, 1 channel acquisition audio input, 1 channel Line audio output built-in digital pre-amplifier, support user custom priority level.

9.1 short circuit output, can control the timing device and other equipment.

10.The interface of 2000W high power amplifier has the function of intelligent power management. When there is no program playing or broadcasting, the output power supply can be cut off automatically to achieve energy saving and environmental protection.

11.Support server remote management, can be accessed where there is Ethernet, support cross-network segment cross-routing.
