1. Input Level Adjustment
This c ontrol a djusts the a mplifier's input sensitivity. Input sensitivity is va ria ble from
200 Millivolts to 8 volts. C loc kwise inc rea ses sensitivity. C ounterc loc kwise dec rea ses
sensitivity. The a mplifier c a n be driven to full power with a wide ra nge of signa l levels.
A lower signa l level will require inc rea sed sensitivity for full power. A higher signa l level
will require dec rea sed sensitivity. Avoid setting sensitivity lower tha n nec essa ry a s this
would introduc e unwa nted distortion.
2. Low Pass Filter Control
This c ontrol is used to set the desired low pa ss frequenc y (50 ~ 150HZ).
The filter a c ts to c ut-off frequenc ies a bove the set-point. In genera l, the selec ted
frequenc y should c losely ma tc h the resona nt frequenc y of the spea ker box.
