9: HIGH: Use this control to adjust the high frequency response of the amplifier.
Rotating the control counterclockwise reduces the high frequency output. Rotating
the control clockwise increases the high frequency output. The High control pro-
vides a range of 33dB of boost or cut at 10kHz.
10: MASTER LEVEL: Use this control to adjust the overall output of the amplifier.
11: LIMIT: This LED illuminates when the amplifier is near clipping. Flashing at
peak playing levels is acceptable. However, if the indicator remains illuminated,
reduce the Master Level control (#10) until the indicator flashes.

internal speaker is disconnected when this jack is used. The impedance the exter-
nal speaker must be 4 ohms or greater!
