Controlling Noise and Distortion
Specifications
MegaWorks 510D 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 510D volume control as your master level control. Examine your computer's sound control software (Mixer program 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 510D reaches a comfortably loud output level when the control is set straight up (12 o'clock).
