5.3.3  Speaker Tapping Adjustments 
 
Both amplifier types have controls to adjust the power output.  
 
NOTE:   However in terms of efficiency and battery capacity that it is preferable to reduce the volume by 
adjusting  the  speaker  taps  to  a  lower  setting  and  leaving  the  controls  turned  right  up  (fully 
clockwise),  rather  than  by  using  the  volume  controls.  Listed  below  are  the  Card  Tap 
configurations.
