R V R ELETTRONICA AUDIGIN-TFT FM Transmitters Broadcast Systems
Introduction
Main Highlights
- The card allows to TEX-TFT exciters the integration into those systems that use digital audio distribution.
It is located on rear panel of the TEX-TFT and is internally connected to the audio motherboard using a 10-pin flat connector. - The card allows the conversion of digital signal into “Left” and “Right” analog signals and then to deliver it to the modulator.
- This card can be added without requiring any special adjustments to the typical analog audio input section; by updating it there is no need to change the exciter firmware.
- The system provides for twelve cyclical queries that allow you to immediately find the active channel and put it on the air.
If a digital input is present, then it is automatically selected by the included
logic. The automatic exchange takes place to select the digital input between balanced (AES/EBU) or optical (TOSLINK). - Through the two trimmers it is possible to adjust the converted digital input level, to normalize the R and L signals with respect to the adjusted level for the analog input.
- The D/A conversion is performed automatically by 24-bit converters using a sampling frequency from 32 to 96 KHz.
- This card supports S/PDIF, AES/EBU, IEC958 and EIAJ CP340/1201 data formats.
