TDM-1630 full duplex digital mobile audio link
TDM 1630 equipment is a digital transceiver designed to be used as a professional full duplex audio link for contribution in radio broadcasting.
It is made of all necessary components to process audio from analog to digital, and modulate carrier uplink, and the opposite processes in downlink.
It works in just one frequency for uplink and downlink. In this way, we will get a mobile broadcast quality full duplex audio link with only a pair of TDM 1630 equipment.
The high output power and reception sensitivity makes it a highly useful system for live news gathering.
