Customizing the MicroSystem CD’s output
The MicroSystem CD has a line output which can feed its audio into an external device.
Uniquely, you can program this output to tailor it for use as:
Note: The subwoofer output is not low-passed. Use the subwoofer’s crossover, set for best blending (about 110Hz).
Programming the line output
Note: If the subwoofer output is set, a small “S” will show in the display to alert you that bass has been removed
from the internal speakers. The subwoofer output sends a summed monaural signal to both left and right RCA jacks.
Using the Bass trim
Fixed-level: With the unit powered off, press Preset 1 and
Snooze/Sleep together for 5 seconds. “L1” will appear in
the display;
Variable-level: With the unit powered off, press Preset 2 and
Snooze/Sleep together for 5 seconds. “L2” will appear in
the display;
Subwoofer output: With the unit powered off, press Preset 3
and Snooze/Sleep together for 5 seconds. “L3” will appear in
the display.
• A fixed-level output that ignores the volume setting (useful for recording or
for feeding the MicroSystem CD’s radio or CD signal to an external receiver
that has its own volume control);
• A variable-level output that responds to the MicroSystem CD’s volume
setting (useful for feeding an external amplifier or powered speaker system
that has no volume control); and
• A subwoofer output that feeds bass to an external powered subwoofer and
simultaneously reduces the bass fed to the MicroSystem CD’s speakers. They
will play louder and will match the subwoofer better.
The Bass trim knob, located on the back of the unit, is used
to adjust the bass level. When the MicroSystem CD is placed
near a wall, the bass can become more pronounced. Setting
the unit away from a wall can sometimes decrease the bass.
Adjust the Bass trim to achieve the desired amount of bass
output.
