Overview
The 4100-1340 TFX Audio Interface Module interfaces the 4100U/4100ES Analog Audio
Controller to existing AUTOCALL TFX AMP-96 amplifiers. It provides an AMP-96 compatible
audio riser by converting the 10 Vrms audio signal from the 4100U/4100ES PDI to a 0.77 Vrms
signal. It provides a transformer coupled output that is trim pot adjustable to 0 dBm +/- 6dB. (This
module is similar to the TFX Riser Driver 2 board).
