WHAT IS AN ATTENUATOR ?

 

ATTENUATORS REDUCE THE DRIVE SIGNAL TO THE AMPLIFIER SO THAT THE INPUT LEVEL OR GAIN CONTROL CAN BE ADJUSTED IN A MORE USEFUL RANGE. FOR EXAMPLE IF THE LINE DRIVER HAS AN 8 VOLT OUTPUT AND THE AMPLIFIER HAS A 100mv (.1volt) TO 2 VOLT RANGE OF INPUT LEVEL, THE GAIN POTS WOULD HAVE TO BE ALL THE WAY DOWN. A 12 db ATTENUATOR WOULD ALLOW THE USER TO ADJUST THE AMP POT TO ABOUT 1/2 ROTATION. MANY HOME TYPE BASIC AMPLIFIERS DO NOT HAVE INPUT LEVEL CONTROLS. THE ATTENUATOR IS PERFECT FOR THIS APPLICATION ALSO.
