Application:
1. Tour Guide with MP3 player (G-MP3T + SPL-32R)
(1) Not only speaker's voice but also MP3 audio file can be heared by listener.
(2) The MP3 audio file can be selected by speaker on G-MP3T, it alsocan be activatedplay automatically byRFID trigger.2.Triggering play by RFID trigger
When the unit is close to RFID trigger, it will trigger and play corresponding MP3 file. The code (0-4095) of triggered fileand triggering range (0-100m) is determined by RFID trigger.
3. Fast switch channel by RFID trigger
When the unit is close to RFID trigger, it will automatically switch channel of wireless transmitter. The code value of RFID trigger is 1, it means it will switch to User Channel "U1". The code value of RFID trigger is 32, it means it will switch to User Channel "U32". The triggering range ((0-100m)is determined by RFID trigger.
4. Realization of video synchronization
This system uses AVT-6 Audio trigger unit to realize the video synchronization function. In figure below, when Mp3 transmitter taken by speaker who entered the triggering range of Audio trigger, Mp3 transmitter would transmit synchronous audio with video, and in different languages. The visitors will hear the synchronous audio of video in their required languages by selecting different RF channel of receiver.
