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.
