Several AGBE transmitters can be used inside of a building or conference room to translate the native language into different languages. Each translator is equipped with a microphone, linked to an AGBE 5W FM transmitter programmed to a specific FM frequency that patrons can receive on their personal FM Walkman. Perfect for conferences or international meetings.
Anshan General Broadcast & TV Equipment Co., Ltd.(AGBE) was established on July, 1998. Many technical personnel in the company have over 20 to 30 years experiences of designing and producing transmitter. It is a main manufacturer producing radio broadcast & TV transmitting equipment in China.
Since the establishment of the company, AGBE has been continuously exploring the brand new development trend of broadcast & TV technology and had a widely technology cooperation with some manufacturers that have the strong influence in the field of broadcast and TV industry from some countries in U.S., France, Italy, etc respectively. The company designed and manufactured a new generation broadcast TV transmitter and CATV wide band network transmission equipment with contemporary international advanced level.
In the product production process, AGBT strictly executes the national standard. In some working procedures like design type, material selection, assemble technique, test technique, aging test, after sale service etc, it also strictly executes ISO9001 control procedure and the qualification rate of equipment leaving the factory can reach to 100%.
Following the coming of digital TV transmitter time, AGBE finished the digital upgrading to the analog product a few years ago and the power amplification part of analog TV transmitter can be compatible with digital function and successfully developed 100W to 2.5 KW digital TV transmitters’ series products. The quality has reached to international advanced level.
AGBE would like to make excellent service to all customers in the principle of” excellent products, reliable reputation and satisfactory price ”.
