About the system
Master volume control. Controls overall volume level. Turning the con-
trol clockwise increases the volume; turning the control counterclock-
wise decreases the volume.
Bass control. 15dB boost or cut of bass at a center frequency of 50
Hz. Turning the control clockwise boosts the bass; turning the control
counterclockwise cuts the bass. The detent, or “click,” in the center of
the control is the “flat” position, zero boost or cut.
Treble control. 15dB boost or cut of treble at a center frequency of
5kHz. Turning the control clockwise boosts the treble; turning the control
counterclockwise cuts the treble. The detent, or “click,” in the center of
the control is the “flat” position, zero boost or cut.
Trimmer.  This control on the circuit module attenuates overall output
level. Its factory setting is the mid position. 
Caution: Setting gain too high may cause distortion.
