Prewired Audio Converter Transformer and LED Indicator Card 

As previously indicated, the AV-V70 includes an installed 70Vrms Speaker Circuit Interface Card prewired to the 
Audio Converter Transformer and the LED Indicator Card. Wiring to the Audio Converter Transformer includes both 
the 25Vrms input wiring and the 70Vrms output wiring (see figure 9).   

 

 

 

 

In addition to the Audio Converter Transformer wiring, the 70Vrms Speaker Circuit Interface Card is prewired to an 
LED Indicator Card, located on the front of the AV-V70 enclosure. The LED Indicator Card includes a 24 VDC LED 
and 70Vrms Speaker Circuit Interface Card trouble LED (see figure 10).
