Microphone Extension Operation
The Microphone Jacks on the Speaker/USB HUB Option provide a convenient way to extend the microphone input
connector to your desktop.
In order to use the MIC jack on the side of the Speaker/USB HUB Option, use the provided Microphone extender cable
(pink connectors) to plug into the rear of the Speaker/USB HUB Option (MIC OUT) and into the MIC input jack of your
sound card (if available). A microphone (that meets the requirements defined for your sound card) can then be plugged
into the MIC jack on the side of the Speaker/USB HUB Option.
Audio Input
The Audio Input on the back of the Speaker/USB HUB Option should be connected to the Line Output jack on the
computer system sound card using the provided cable (Lime Green connectors). The Speaker/USB HUB Option has a
built-in amplifier (Amp). If the Audio Out of the computer sound card has only Speaker Out, reduce the volume control
on the computer system.
NOTE
If the Audio Out of the computer supports both Speaker Out and Line Out, Please use the Line Out function
(For more information, refer to the documentation that comes with your computer).
