Structure
SIP2101T uses a 400MHz ARM processor architecture and a professional bidirectional audio codec . The arm processor isresponsible for data transmission, user command analysis and execution, and power amplifier interface control.
The professionalaudio codec is responsible for audio input and output. Its internal structure is as follows:
Its appearance structure is as follows:
Application
Outdoor loudspeaker
Desktop walkie talkie
intercom terminal
PLAY
The network audio equipment can receive the audio stream from the network, and convert it into an analog audio signal for output after being decoded. The figure below is a standard playback application scenario.
The SIP2101T/SIP2103T network audio module is used as a playback terminal, and only needs to increase the power supply and external power amplifier. It can be used as a device alone, or integrated in other audio equipment (power amplifier, or active speakers, etc.) to make it a network audio playback terminal.
INTERCOM
SIP2103T can be used in a two-way SIP intercom system
The broadcast intercom host can use our company's broadcast system control software, broadcast equipment, network microphones, etc., or use the SIP server prepared by the user.
This VoIP Telephone Circuit is ideal for access system, railway applications, tunnels, highways, campus, parking lot, power stations, oil&gas station, marine applications, underground mining, retail banking, clean rooms, firefighter, taxi, industrial, prisons, parking-lots, power stations, chemical plants, etc.
The company is a national high-tech enterprise with high-tech products.
We have set up R & D center, chip factory and comprehensive manufacturing base in Guangzhou. The factory covers an area of 8500 square meters. The company is committed to building international top brands.
We have a professional and strong R & D team to provide further customization in terms of firmware, software and solution requirements.
