Controlling
Noise and
Distortion
MegaWorks THX 5.1 550 has
moderately high input sensitivity, so
it may amplify the hum and hiss
inherent in some audio program
sources. Any noise is not due to a
fault in the speaker system.
You can minimize background noise
as follows:
❒ Use the MegaWorks THX 5.1
550 remote control as your
master volume control.
❒ If your speaker system is
connected to a computer, adjust
the settings of your computer’s
sound control software. (If you
are using Creative Sound Blaster
software, this would be the
Surround Mixer application).
Turn off any input controls that
you do not need, such as
Microphone, and set the
remaining input controls to about
70% of their maximum volume.
❒ Adjust the master output volume
of your sound control software,
such that your speaker system
reaches a comfortably loud
volume in its default volume
settings.
