Important Notice

The serial number for the MegaWorks THX 2.1 250D is located on the subwoofer. Please write this number down and keep it in a secure area. This is for your security.

CAUTION

Take care to prevent accidental operation of your new loudspeaker system at excessive sound pressure levels! In a typical personal computer installation, the MegaWorks THX 2.1 250D satellite speakers are less than a meter from the listener.

Notes

•Treble settings can be adjusted in the same way as for the speakers.

•When you disconnect the headphones, the system will revert to a preset default master volume setting (two Level Indicators lit), in order to prevent high headphones volume levels from being applied to the speaker system.

Controlling Noise and Distortion

MegaWorks THX 2.1 250D 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 2.1 250D 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.
