The Master Section gives the operator overall control of the settings that
apply to all inputs.
1. MASTER - BASS: 

Adds or subtracts bass to the MATRIX-200 output.

Adds or subtracts the mid-range frequencies produced

by the MATRIX-200. This control will add vocal clarity or instrument 
presence.
3. MASTER - TREBLE: 

Adds or subtracts the high range frequencies in the

overall mix.
4. MASTER - PLAYBACK: 

Controls the volume of the playback input jacks,

shown as No.23 on the diagram (right).
5. DIGITAL EFFECTS - LEVEL: 

Controls the mix level of the built in effects.

The MATRIX-200 features eight versatile

settings designed to suit a host of differing musical needs and tastes such
as Large Hall, Large Room, Small Hall, Small Room, Echo, Slap Back,
Chorus Reverb and Chorus.
7. DIGITAL EFFECTS SOURCE:

MASTER/INPUT SWITCH: Controls routing

internal DSP effects to either MASTER section, or to individual channels.
8. MASTER - POWER: 

When this LED is illuminated, the MATRIX-200 is

connected to AC mains voltage and powered on.
9. MASTER - VOLUME: 

Controls overall volume of the MATRIX-200

except for the playback inputs (See Description 4).

The Input section of the MATRIX-200 controls various aspects of the exter-
nal audio sources which can be plugged into the mixer, including micro-
phones, guitars, keyboards and certain other devices equipped with
either 1/4” jacks, 3.5mm stereo jacks, or microphone outputs
10. INPUT - EFFECTS: 

Controls level of each individual channel routed to

digital effects section when Effects Master/Input switch is in Source posi-
tion. These controls are not active when Effects Master/Input switch is in
Master position.
11. INPUT – TONE:

Adjusts tonal balance of each individual channel.

Turning tone counter-clockwise adds bass, while turning tone clockwise
adds treble.
12. INPUT – PAN (PAN/BALANCE on Channel 5):

Controls routing mono

signals from Channels 1-4 to either Left or Right speakers. Place PAN in
neutral position to keep source centered. Turning this control from center
moves the image of the performer on this channel towards one side.
Either fully clockwise or counter-clockwise will place this performer in
either the right or left side alone. PAN/BALANCE on Channel 5 balances
stereo image on stereo sources connected to either STEREO LINE 1/4”
jack (15) or stereo MP3/CD 3.5mm jack (16), or pans mono source 
connected to INSTRUMENT 1/4” jack (17).
13. INPUT – VOLUME:

Controls volume of each individual channel.

Unbalanced 1/4” jack inputs for channels 1-4. Will

accept wide variety of music sources. Tip is connected to signal (+), while
sleeve is connected to signal ground (—).
15. INPUT – STEREO LINE:

1/4” stereo jack to connect stereo sources

with line level output(s).

3.5mm stereo pin plugs (TRS style) connects so

that your portable music source(s) can be used as an input to play
through your MATRIX-200.
17. INPUT – INSTRUMENT: 

1/4” jack input for string instrument, such as

acoustical guitar with passive pickup, or electrical guitar. 
18. INPUT – MIC: 

Balanced XLR inputs to connect low-impedance micro-

phones to channels 1-4. These inputs will accept virtually any micro-
phones, both dynamic and condenser. All four XLR inputs are phantom
powered to provide voltage required by condenser microphones. These
inputs will also accept any mic-level balanced signals.

1/4” jacks to connect

external processing device, such as compressor or equalizer to 
MATRIX-200. Each 1/4” jack has input and output; one jack for Left
channel and one jack for Right channel. SLEEVE on 1/4” jack is connect-
ed to the ground. RING must be connected to the input of external
device, and TIP must be connected to the output of external device. Please
refer to the diagram labeled “Y-Cable Setup” on Page 7 of this manual
for a graphic depiction of this.
NOTE: 

Different processors may have a different configuration than the

MATRIX-200 on their connectors. Please review the manual information
of the external processor before assuming it is the same as the 
MATRIX-200. If the external processor uses a different connection 
standard, then you will likely need to buy adaptors to properly connect
the two units together.
NOTE:

Do not insert Mono 1/4” jacks into insert jacks.

This 1/4” jack is used to connect

footswitch to remotely mute digital effects and master volume. 
22. RECORD OUTPUTS: 

RCA jacks to connect stereo recording device 

to MATRIX-200. This record output is unaffected by the Master volume
control.
23. PLAYBACK INPUTS: 

RCA jacks used to connect stereo source to

MATRIX-200. This input bypasses all controls, including Master Volume
(9) and Equalizer (1), (2), and (3), and is controlled only by playback
level control (4). It is also not affected by Mute Footswitch (22).
