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.

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.
