MICROPHONE INPUT JACK: A microphone can be used to record voice or music
for a variety of software applications. To take advantage of this feature simply
connect a standard high quality dynamic or self-powered electret microphone
to this jack.
NOTE: Microphone not included. The microphone plug required is a mini type
measuring 3.5mm (1/8").
MASTER LEVEL CONTROL: Under normal circumstances, this control is used to
control the volume level of the system. Turning this control clockwise increases the
volume while turning it counterclockwise decreases volume. When either the BASS
or TREBLE buttons are activated, this control acts to raise or lower the respective
function that has been selected. The relative position of the MASTER LEVEL
CONTROL is displayed in the IntelliBase control panel in the form of a slider where
0 represents minimum and 256 represents maximum.

CONTROL, this button is used to increase or decrease the low frequency response
of the system. When the BASS control is active, the indicator light above the button
is illuminated. The relative position of the BASS control is displayed in the
IntelliBase control panel in the form of a slider where 0 represents minimum and
256 represents maximum. Waiting for a short period or depressing the button
a second time deselects the BASS function and enables the MASTER LEVEL
CONTROL to be used as a volume control.

CONTROL, this button is used to increase or decrease the high frequency response
