Hearing damage, prolonged exposure to excessive SPL
B-52 Pro-Audio speakers, including the MATRIX-200, are capable of producing sound pressure levels (SPL) sufficient to cause per-
manent hearing damage to performers, production crews or people in the audience. Hearing protection devices such as ear-plugs
are recommended. Caution should be taken to avoid extended exposures to SPL levels in excess of 85 dB.
Amplifier Module Precautions
Do not attempt to service the MATRIX-200 by yourself. Refer all servicing to a B-52 Pro-Audio Authorized dealer. Service
is required when the MATRIX-200 amplifier has been exposed to liquids or suffered damage. Do not operate the unit if
liquid has spilled into the amplifier. Immediately remove the power cord from AC mains power if such an event should
occur.
WARNING – Shock Hazard
To reduce the risk of fire or electrical shock, do not expose this unit to rain or moisture. Do not operate your MATRIX-200 near a
pool or other standing water. Make sure all blades on the polarized power plug are fully inserted into the power source. Ensure
the power cord is not stretched, pinched or otherwise abused. Ensure the power cord is routed to avoid foot traffic. Your MATRIX-
200 amplifier should be cleaned only with a dry cloth.
The MATRIX-200 Powered Stereo Mixer with DSP
Cautions
1) When placed on slick, smooth or slippery surfaces, vibrating speakers may move from their original location. Precautions should
be taken to insure the system does not fall off of a raised stage or platform.
2) Please turn the volume down prior to turning the system on to prevent possible damage to the speakers.
3) If you are using an optional active subwoofer with the MATRIX-200, be sure all cabling is connected to the MATRIX-200 from
thesubwoofer,thesubwoofer’svolumecontrol(s),andthevolumecontroloftheMATRIX-200areturnedallthewaydown,
before either unit is powered on.
4) After connecting your source(s) to the MATRIX-200, make sure your MATRIX-200 and signal sources have their volume controls
turned all the way down before powering on the MATRIX-200 to avoid turn on thumps that could damage your speakers.

MATRIX-200 FRONT PANEL CONTROLS
MASTER SECTION
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 out-
put.
2. MASTER - MID: Adds or subtracts the mid-range frequencies pro-
duced 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.
6. MASTER - DIGITAL EFFECTS: The MATRIX-200 features eight versa-
tile 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 rout-
ing 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).
INPUT SECTION
The Input section of the MATRIX-200 controls various aspects of
the external audio sources which can be plugged into the mixer,
including microphones, 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 rout-
ed to digital effects section when Effects Master/Input switch is in
Source position. 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 clock-
wise 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 chan-
nel 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.
14. INPUT – LINE: 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).
16. INPUT – MP3/CD: 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
microphones to channels 1-4. These inputs will accept virtually any
microphones, both dynamic and condenser. All four XLR inputs are
phantom powered to provide voltage required by condenser micro-
phones. These inputs will also accept any mic-level balanced signals.
PATCH SECTION
19. INSERT INPUT/OUTPUT LEFT and RIGHT: 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 connected to the ground. RING must be connected to the input of
external device, and TIP must be connected to the output of exter-
nal 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 con-
nect the two units together.
NOTE: Do not insert Mono 1/4” jacks into insert jacks.
20. EFFECTS SEND/RETURN LEFT and RIGHT: 1/4” jacks to connect
external effects processor. 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 connected to the ground. RING must be connected
to the input of external processor, and TIP must be connected to the
output of external processor. 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 instruction
manual information of the external processor before assuming it is
the same as the MATRIX-200. If the external processor uses a differ-
ent connection
standard, then you will likely need to buy adaptors to properly con-
nect the two units together.
NOTE: Do not insert Mono 1/4” jacks into insert jacks.
21. FOOTSWITCH EFFECTS/MUTE: 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 vol-
ume 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).

MATRIX-200 REAR PANEL
1. LOUDSPEAKER OUTPUTS – RIGHT and LEFT:
Connect to right and left speakers according-
ly. Use only speakers supplied with MATRIX-
200 System.
2. SUBWOOFER OUTPUT: XLR output to connect
optional active subwoofer to the MATRIX-200.
While the MATRIX-200 is a full range active
system, the very low frequency performance
can be enhanced by adding an external sub-
woofer. The subwoofer will both extend the
range of the system, and add increased low
frequency output ability. The subwoofer XLR
output jack has both left and right channels
combined, minus the
higher frequencies sent to, and reproduced by
the satellite speakers. The XLR output only has
signal present when the “sub sw” (sub switch;
item # 3) is in the on position.
3. SUBWOOFER ON/OFF: Used to activate
subwoofer output (2), and to activate high
pass filters on main channels. This improves
performance of the system by causing a more
ideal acoustical summation of the subwoofer
and main speakers. It does so by limiting
cone excursion, and by increasing the head-
room available to both the speakers and
amplifier.
4. HEADPHONES: 1/4” stereo jack used to
connect headphones for monitoring when
speaker use is not possible, or if headphones
are preferable. NOTE: This jack is inactive
if the speaker cables are inserted into the
speaker output jacks (1).
5. VOLTAGE SELECTOR SWITCH: DO NOT
CHANGE THIS SETTING WITH THE AC MAINS
POWER ATTACHED! This switch is only used to
modify the unit when it is transported to a dif-
ferent location with a different available AC
mains source (such as moving a unit bought
in the USA to Europe). Please check that this
switch is in the appropriate position for your
local electric source.
WARNING: Using an improper setting on this
switch can destroy the MATRIX-200, create
an electrical hazard and void your warranty!
Do not change this setting unless you must to
match to the AC mains power available.
6. POWER ON/OFF: Press this switch to turn
the MATRIX-200 on or off.
7. AC INLET: Male IEC AC mains connector
for standard detachable AC mains cords.
This cord will also need to change if the unit
is moved between regions with different AC
mains voltages. It will require an AC mains
switch setting change as well.
8. FUSE HOLDER: This fuse depends on your
local AC Mains voltage. For 115V setting,
this fuse is a 5amp T5AL. For the 230V set-
ting, the fuse used is a T2.5AL as shown.
CAUTION: Connect the power cable only after you have absolutely made sure that the local mains
voltage matches the voltage specified on the device. If you connect to the wrong voltage, you may
destroy the electronic components of the MATRIX-200 system.
