1.2 EQUIPMENT 
DESCRIPTION 
The DIGITAL Transmitter is part of a combined Digital Studio to Transmitter Link that provides broadcasters with six 
uncompressed program channels and a data channel to meet the requirements of consolidated operations. It provides the 
maximum number of high quality program channels over a single RF channel. 
The TFT Digital STL consists of a transmitter and receiver pair that accommodates up to three AES/EBU (stereo) inputs 
or up to six discrete audio channels. The transmitter has a 2-Watt output and delivers them uncompressed in a 
configurable digital method to the receiver. Sample rates of 32, 44.1, and 48 ks/s are supported. The method of 
modulation is a function of the number of channels and sample rate and is configurable from a front panel jack that can 
be connected to a laptop PC. The RF system is frequency agile and set by software in the transmitter and receiver. 
The frequency and input/output configuration of both the transmitter and receiver can be set for optimum values of 
threshold and modulation via a laptop PC that can be connected to a modem. User-friendly software with a graphical 
user interface (GUI) is provided with each system. The transmitter and receiver can be remotely controlled over an 
internet or LAN connection.
