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.
