Controlling Noise and Distortion

Specifications

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.
