Introduction
The Matrix K is a small, multi-function, professional audio system, which integrates a
microphone pre-amplier with +48V phantom power, a Direct Box for connecting a guitar or
bass, a 3-channel dual bus stereo mixer and dual headphone amplifiers. The unique dual bus
design makes Matrix K the best choice for use with a computer based hard-disk recording system
or when you want to add a microphone to a digital instrument with line in and line outs. For
example, use the Matrix K with a synthesizer with a sampling function or to add vocals to a
digital piano with line inputs and outputs.
After connecting Matrix K to your computer, your new music-making system will include
many practical and convenient functions. Matrix K features not only inputs and outputs for
transmitting signal to/from computer but also two headphone outputs with volume control
knob for different monitoring needs. Matrix K also features different connectors such as Line
In, Monitor Output, gain adjustable Mic In and Guitar In to satisfy all of your music-making
needs. In addition, the Line In of Matrix K can receive un-balanced signals and convert into
balanced signals. Furthermore, Matrix K provides +48V phantom power to support professional
microphones.
Matrix K is bus powered when it connects with computer via IEEE 1394 port (Matrix K FW)
or USB port (Matrix K USB). It works with full functions without any other extra power adaptor
is needed.
Hardware Direct Monitor is another advantage for Matrix K users. Signals from the Line
In, Mic In or Guitar In can be sent to the headphone outputs or monitor speakers directly by
pressing the Direct Monitor button. Un-pressing the button will route those signals to the
computer and then out through Matrix K back to the headphone output or monitor speakers. This
is a convenient function to compare the sound before and after processing and recording on the
computer.
Besides working with computer, Matrix K can be used as a stand-alone device to add a
microphone or guitar to a keyboard that has a line in and out. Simply connect the audio matrix
and you can easily add a microphone or guitar to a digital piano with speakers or increase in the
number of headphone outputs.
Matrix K is a unique utility mixer that ts many different audio applications because of its
exible and powerful design. It’s especially useful in a small computer recording environment.
You’ll nd that Matrix K will come in handy for many different situations and that it’s quality
and cost performance is outstanding.

Driver Installation and Removal
Matrix K is an external digital audio device. You can start your music making just by an
IEEE 1394 cable (Matrix K FW) or USB cable (Matrix K USB) to connect with computer. After
installing driver, Matrix K FW can be used immediately.
Matrix K USB can work properly without any extra driver in Windows XP.
Both Matrix K FW and Matrix K USB will work properly without extra drivers in MAC OS X.
Driver Installation
The following is brief of Matrix K FW’s driver installation step in Windows XP.
Please note, do not connect Matrix K FW with computer before the installer ask you to do so.
Please insert the driver CD which is within the pack of Matrix K FW into CD-ROM drive.
The installation will start automatically later. Please select “Install Matrix K FW” in main menu
to start the driver and control panel installation.
Select “Next” to go on.
Please use the default path to install driver and control panel. Select “Next” to continue.
12
Select “Next” and go next step.
Select “Continue Anyway” to install.
Please connect Matrix K FW with computer by IEEE 1394 cable when this dialog shows up,
and select “Next” to continue.
Matrix K User's Manual 13
Matrix K User's Manual
Please ignore this dialog and select “Continue Anyway” to continue.
Please wait for the installation to be nished. The installation is completed when this screen
disappear.
After installing, there is a small Matrix K icon on the task bar. Open Matrix K FW’s control
panel by double clicking this small icon.
Driver Removal
To remove Matrix K FW, please go to “Control Panel \ Add or Remove programs” and
remove it.
Control and Settings
On Windows XP, besides the hardware controllers, most of the controls and settings of Matrix
K are set by its control panel. Matrix K FW has its own control panel. We will discuss about it
later.
Matrix K USB uses the volume control of Windows XP. It does not have its own control
panel, neither the ASIO driver supporting.
On MAC OS X, both of Matrix K FW and Matrix K USB use system control to adjust the
settings.
The following is some screen shots of Matrix K settings on MAC OS X. (The device name is
just for reference.)
