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 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).
This section provides information on the speaker audio functions.

Using the USB (Universal Serial Bus) HUB Featuers
Universal Serial Bus (USB) is an innovation that conveniently connects
different devices to your computer. USB enables you to have the flexibility to
connect your mouse, keyboard, and other devides to the monitor instead of the
computer. The Speaker/USB HUB Option provides a 4 port USB HUB that will
enabel you to connect a chain of up to 120 devices on a single USB connection.
You can “hot-plug” USB devices, that is, you can attach the devices while the
computer is on. You can also disconnect USB devices while maintaining “Plug
and Play” auto detection and configuration. This monitor comes with an
intergrated BUS-power USB hub that can have up to four other USB devices
attached to it. The Speaker/USB HUB Option has an intergrated BUS-powered
HUB that meets the USB 2.0 Specification for Full Speed Devides, allowing up
to 4 low power (<100 mA each) USB devices to be attached.
USB HUB Jacks External USB 1.1 low power devices such as
keyboards and mice can be connected to these
ports.

of the side view.
Notes :
To activate the USB hub function, the
Speaker/USB HUB Option
must be connected to a
USB compliant computer (OS) or another hub with the USB cable(enclosed).
When connecting the USB cable, check that the shape of the connector at the cable side
matches the shape at the connecting side.
High powered devices (such as stand alone scanners and camera’s etc.) can not be
connected to the USB HUB ports. Self powered devices (use an extermal AC adapter to
meet the high power repuirement) can be connected to the USB HUB port.
The USB HUB is compliant to the USB 2.0 Specification and will support low speed and full
speed devices (same as USB 1.1). The HUB can not support high speed devices and will
connect them as full speed devices.
Connecting USB devices
1. Insert the USB cable into the square USB connector of the Speaker/USB HUB
Option as shown is the diagram on the left. Then, insert the other end of the
USB cable into the rectangular USB connector on a USB-compliant computer
or USB hub as shown in the diagram on the right.
2. Insert the USB cable for USB-compliant devices into the rectangular USB
connector in the monitor as shown in the diagram on the right.
