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.
