Stereo Audio Digital Transmitter

INTPRO10 Audio System is the best of stereo digital audio technologies. This system uses a hi reliability DSP system to process the audio signal. Hi quality DAC and ADC sample the Audio signal to very hi frequency (over-sampling technique) in order to even improve the characteristics of all audio path.

This approach allows a very clear audio for this kind of digital transmitter

The Radio transmission is fully digital DSS technology for 2.4GHz Band and GFSK for 380MHz  – 460MHz.

All data are AES encrypted.

The Receiver have two complete receivers used in diversity mode to improve the performance.

All received audio is recorded on onboard SD memory Card.

A remote power down features is used on Transmitter.

A transmitter can be a separate piece of electronic equipment, or an electrical circuit within another electronic device. A transmitter and a receiver combined in one unit are called a transceiver. The term transmitter is often abbreviated “XMTR” or “TX” in technical documents. The purpose of most transmitters is radio communication of information over a distance. The information is provided to the transmitter in the form of an electronic signal, such as an audio (sound) signal from a microphone, a video (TV) signal from a video camera, or in wireless networking devices a digital signal from a computer. The transmitter combines the information signal to be carried with the radio frequency signal which generates the radio waves, which is often called the carrier. This process is called modulation.
