Introduction

The Matrix K is a small, multi-function, professional audio system, which integrates a

microphone pre-amplier 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.
