MegaWorks THX 250D has
moderately high input sensitivity, so
it may amplify the hum and hiss
inherent in some audio program
sources (more common in analog
rather than digital sources).
Any noise is not due to a fault in the
speaker system. You can minimize
background noise as follows:
❒
Use the MegaWorks THX 250D
volume control as your master level
control. Examine your computer's
mixer software (for example,
Surround Mixer in Sound Blaster
software). Turn off any inputs you
don't need (Microphone, for
instance). Set the remaining input
volume controls to about 70% of
their overall scale.
❒
Adjust the sound control program's
master output level so that the
MegaWorks THX 250D reaches a
comfortably loud output level.
