Introduction
Thank you for purchasing one of the critically acclaimed Octet Matrix Audio wireless speaker
systems. Please read through the entire manual before attempting to install your wireless
speaker system. Wireless setup & operation can sometimes be problematic, but by following
the guidelines in this manual, you should have your system up and running optimally with
few problems.
Features
Octet Matrix Audio has set the standard in the wireless speaker category by integrating
uncompressed digital audio wireless transmission with high efficiency Class T amplification in
convenient, easy to use systems. Utilizing the 5.8 GHz wireless band, the DE7/BA21 wireless
speaker systems offer trouble free operation in most home environments.
Octet Matrix Audio wireless speaker systems offer the following category leading features:
44.1 kHz/16 bit (-DW50 systems) or 48 kHz/24 bit (-DW60 systems) uncompressed
digital audio for audiophile quality wireless audio transmission.
Completely independent right and left monitors with integrated wireless receiver and
50 watt or 60 watt class T amplifier (100 watts or 120 watts total).
Minimizes interference possibilities by operating in the less crowded 5.8 GHz wireless
band.
Wireless audio link produces less than 1.5 milliseconds latency (delay) making Octet
Matrix Audio wireless speakers ideally suited for use in home theater systems and
high end gaming systems. Other wireless systems can have as much as 30 milliseconds
latency, making them unusable in many of these installations.
High efficiency Class T amplifiers deliver high power at low distortion with very little
excess heat generation. Class T amplifier architecture provides high definition audio
performance while operating at class D amplifier efficiency.

1) Choose Source, based on output type, from group 1 or 2.
2) Choose receiver/amplifier output from 1a, 1b, 2a, 2b, or 2c.
3) Hook up receiver/amplifier output chosen in step 2 to the DWT4416 or DWT4824 input
indicated.
4) Follow the steps in Wireless System Testing.
Wireless System Testing
Follow the instructions here prior to calibrating the system. This will allow you to confirm
proper wireless operation with the components in their intended locations. If problems are
found in this step, follow the Troubleshooting Guide to resolve the issues before continuing
with installation. Please follow these instructions prior to drilling any holes or permanently
mounting any components.
Transmitter
The DWT4416/DWT4824 transmitter can be placed anywhere convenient. However, do not
place it on top of other devices that generate large amounts of heat such as receivers,
amplifiers, DVRs, etc. Keyhole patterns on the bottom of the transmitter case allow the
DWT4416/DWT4824 to be mounted on a wall, or on the side or back of a home
entertainment system cabinet.
Rotate the DWT4416/DWT4824 transmitter volume knob to its centered position (straight
up). Connect the system components as determined with the System Setup Flow Chart and
connect the power supply first to the transmitter and then into the wall outlet. Place the
transmitter in, or near, the desired final location.
Wireless Speakers/Wireless Amplifier
Temporarily place the wireless speakers in or near the desired final positions. The locations
must be close to power outlets. Rotate the volume knobs to the centered position (straight
up).
Testing the System
After the components are set up as described above, play some audio material through the
system at a low to moderate system level. DO NOT USE THE OCTET MATRIX AUDIO SETUP CD
FOR THIS STEP! YOU MAY DAMAGE EQUIPMENT, YOUR HEARING, OR BOTH.
The first time you operate the system, it may take a moment or two for the wireless link to
establish a solid connection, and may even produce some crackles and pops while connecting.
Once the speakers have locked onto the transmitter confirm that the system operates

Page 10

correctly without audio dropouts or crackling. If the system does exhibit any of these
problems, use the troubleshooting charts to resolve the issue before continuing.
Component Installation
You are now ready to permanently mount the system components. If you will be mounting to
walls, try to screw into wooden studs. If you can’t locate studs suitable for your installation,
use wall anchors capable of holding the weight of the component. If you don’t have a stud
finder, mark the desired location and drill a test hole with a drill the same diameter as the
screw body. If you hit a wood stud, then use the holes and screw directly into the stud. If you
don’t hit wood, drill out the same holes with a drill diameter suitable for wall anchors that
will hold the component weight and screw into those.

DWT4416/DWT4824 Transmitter Mounting
If you choose to mount the transmitter, print out this page. Make sure that Page Scaling in
the print settings is set to “none”. Use a nail, screw tip, or other sharp object to mark the wall
or other mounting surface by puncturing the paper at the two crosshairs.
If the planned mounting space is tight, use scissors to cut around the template outline and
position the template exactly where the transmitter will be mounted. Puncture the paper at
exactly the location of the screws (instead of at the crosshairs) or the transmitter outline will
shift up to an inch from the expected location.
If you cannot locate a stud to screw into, drill a ¼” hole at each marked location and tap in
screw anchors. Fasten screws to a stud or anchors leaving approximately ” gap between the
wall and the bottom of the screw head.

Page 12

Wireless Speaker Placement/Mounting
The “L” or “R” appended to the end of the model number indicates which channel that
speaker will receive from the transmitter. Octet Matrix Audio wireless speakers can be placed
on speaker stands, bookshelves, or on any flat, stable surface. They can also be mounted to
walls with wall mount brackets (sold separately). If you choose to mount the speakers to a
wall, make sure you screw into a stud, or use a wall anchor capable of holding the weight of
the speaker. Each wireless speaker must be located near a wall outlet.
Final Verification & Optimization
You will use the Octet Matrix Audio Setup CD for the final verification and optimization step.
If the transmitter and speakers will be located in different rooms, we recommended that you
temporarily set up the wireless speakers near the transmitter location. Actual speaker
location is not important, but they should be directed towards the transmitter so you can
easily hear them while confirming setup and adjusting the transmitter output.
The test tracks on the Octet Matrix Setup CD are:
1) Introduction
2) Left-Right Channel Identification
3) Left-Right channel phase confirmation
4) Track 5 warning
5) 1 kHz tone, 0 dBFS
Channel & Phase Verification
1) Set the volume controls on the transmitter and both wireless speakers to 12:00 (straight
up). Turn or set the volume control on the source, receiver, or amplifier to 9:00 (¼
volume).
2) Insert the Octet Matrix Audio set up CD into a CD player, DVD player, or Blu-ray player.
If the CD doesn’t start playing automatically, point the player to track 1 and then hit
play. When the Octet Matrix Audio Setup CD introduction starts, adjust the source,
receiver, or amplifier volume to a comfortable listening level.
3) Track 2 is a channel identification track and will alternate between spoken “Left
channel” and “Right channel” routed only to the respective channels. Confirm that “Left
channel” is coming from the left wireless speaker and that “Right channel” is coming
from the right wireless speaker. Left channel speakers will have an “L” appended to the
end of the model number on the speaker label. Right channel speakers will have an “R”
appended to the end of the model number on the speaker label.

Page 13

4) If the channels are reversed, check the wiring into the transmitter and re-route the
wires if necessary. If the wiring to the transmitter is correct, check all other system
wiring and fix any incorrect channel routing.
5) Track 3 is a phase verification track to confirm that speaker to speaker phase is correct.
To use this track effectively, you should be centered between the speakers and 3' - 5'
away. The track alternates between the spoken phrase “In phase” followed by pink
noise played in phase, and “out of phase” followed by pink noise played out of phase.
Both the voice introduction and the pink noise will be either in phase or out of phase.
6) When everything is set up correctly, you should hear:
a. In Phase - the voice and the pink noise will have a clearly defined point of origin
centered between the speakers.
b. Out of Phase - the voice and pink noise will have no clearly defined origin and may
even sound as if the sound originates outside of the speakers.
c. There will also be a distinct difference in bass levels with the pink noise. The pink noise
will sound fuller (more bass) when in phase, and thinner (less bass) when out of phase.
7) If you hear the opposite effects, check the wiring into the transmitter. In some cases,
the equipment setup or environment can cause confusing results. If the wiring seems
correct, try moving your listening position towards the speakers and move slightly to
one side of center, listen, and then move slightly to the other side of center and listen. If
you still don’t hear what you think you ought to, try reversing only the left input wire
polarity and perform the phase test again.
Dynamic Range Optimization
1) Determine the maximum system level via the main system volume control. If you have
several sources (CD player and DVD player, for example), you must use the source with
the highest analog output with the 0 dBFS test signal. See Advanced Test Procedures
section for determination of the source with the highest output.
2) Set the transmitter volume control to the 9:00 position.
3) Confirm that both wireless speaker volume controls are set to the 12:00 position.
4) Disconnect all other speakers and set the main system volume control to the maximum
level determined in step 1.
5) Place the Octet Matrix Audio test CD into the source selected in step 1 and select track 5
(or select the 0 dBFS track copied to MP3 player, iPod, iPhone, etc).
6) Adjust the transmitter volume control up until you hear distortion. The onset of
distortion will be obvious, with a clear transition point. Back the transmitter volume
control off slightly until the distortion disappears. This setting should not have to be
changed again unless system component changes are made.

Advanced Test Procedures
Determination of highest output source
1) You should have a voltmeter or a computer with a soundcard* in order to determine
which source has the highest output level for a given input signal. You do not need a
calibrated measurement system because you only need to determine the relative output
of each source with a known signal (the Octet Matrix Audio 0 dBFS test tone). If you have
a voltmeter, play track 5 through each source and measure the voltage at the source
output. The source output that registers the highest voltage is the source you should use
for the dynamic range optimization setup. If you do not have a voltmeter, you can
download one of the audio level meters in the Resources section to a computer with a
soundcard (preferably a laptop) and connect the source outputs to the soundcard input to
determine the highest analog output.
2) If you want to skip the technical nonsense and trust your ears, make a copy of the Octet
Matrix Audio Test CD and play Track 5 in two sources at the same time. Set the Main
System Volume to ¼ volume and switch the source selector from one source to the other
to determine which source sounds louder for a given Main System Volume setting. The
source with the highest output should be used for Dynamic Range Optimization.
*Any AC voltmeter or PC soundcard will do. You will be measuring sine waves and are interested in relative levels, so it
doesn’t matter if your meter is an RMS responding meter or an average responding meter, or even if it’s out of calibration. If
none of this makes sense to you, don’t worry. The relative values you measure with anything other than a truly broken
meter or soundcard will give you the results you need.
