DiamondBoxx XL2 User manual

Model XL2

Congratulations on your purchase of the highest performance
portable Bluetooth speaker / amplifier system available. Our
design goal was to build something that could be heard over a
noisy gathering or environment while sounding great, as well as
being completely portable, without need for nearby electricity.
We used the highest quality materials for each intended purpose.
Wood Aluminum Titanium Lithium Leather Neodymium
Put together along with a 660 Watt RMS (1000W Max) Class A/B
12 channel high fidelity amplifier in a tri-amped or bi-amped
arrangement (mode dependent) with active crossovers and DSP
for the best sound possible in the lightest package with the
longest battery life.
Your DiamondBoxx was hand-built, cared for properly it should
provide you with many years of listening pleasure.
Happy Listening!

Battery Life
After a full recharge, the DiamondBoxx will play 3–50 hours depend-
ing on volume level, mode, music type and which battery option your
DiamondBoxx has. Charging is accomplished by plugging in the
supplied charger to the rear panel. DiamondBoxx CAN BE played
while charging.
If the LED on the charger is RED it is charging. When it turns GREEN
the DiamondBoxx is fully charged. If playing music while charging,
the charger LED might not ever turn green or might blink red to the
beat of the music, this is normal. The battery can be charged at any
time, with the DiamondBoxx playing music or not.
The Diamond
Besides its good looks, the 2 Carat CZ Diamond serves as the battery
level indicator while the DiamondBoxx is playing. When it looks
WHITE (really a combination of Red, green and blue colors so it may
look different from different angles) the battery is more than 25%
charged. If your diamond turns RED the battery charge level is less
than 25%. (It may blink between colors a bit with music playing, this is
The Power Button
This controls the power to the DiamondBoxx.
Push in to switch power on.
Push again to switch DiamondBoxx off.
Volume Knob
We suggest if the music source being connected to the DiamondBoxx
also has a volume control, leave that device's control at MAX volume
an use the DiamondBoxx volume control to control the level. This will
provide the cleanest sound with lowest background noise floor.
The LED Bar Display
The LED bar display can tell you three things.
1. The battery charge level in 10% increments
2. The output volume level relative to maxium output
3. The TWS (True Wireless Stereo) setting mode
When the DiamondBoxx is first turned on the LED display will display
the battery level for about 5 seconds. After this the LED bar will
become a stereo output volume level indicator. It will display TWS
mode only while setting up the TWS connection.

TWS Function
To wirelessly connect two 2nd generation DiamondBoxx perform the
following:
1. Power on the DiamondBoxx that will be the MAIN unit
2. Connect the Bluetooth device to it
3. Power on the DiamondBoxx that will be SECONDARY unit
4. Press and hold the TWS button on Main DiamondBoxx until the
LED under the letter “M” blinks rapidly, then release button.
5. Press and hold the TWS button on the Secondary DiamondBoxx
until the LED under the letter “S” blinks rapidly, then release button.
6. Wait for up to 2 minutes for the DiamondBoxxes to form a secure
connection. (It may pause the music on the Bluetooth device trans-
mitting music so you may have to restart your music)
7. If after 2 minutes you are unable to make a connection press and
hold the TWS button on both DiamondBoxxes (one at a time) until
the LED under the letter “C” flashes rapidly and then release button.
This should clear the TWS system, now start from step 1 again.
NOTE: the 2 DiamondBoxxes must be less than 30 feet from each
other typically.
This is used for switching between SQ (Sound Quality)
mode and SP (Sound Pressure) modes, as well as con-
trolling the TWS (True Wireless Stereo) function. A
quick press and release of the button will toggle the
DiamondBoxx XL2 between SQ mode and SP mode.
The indicator on the Mode switch will illuminate blue

The Bluetooth
To connect your Bluetooth device:
1. Turn on the DiamondBoxx
2. Reduce the DiamondBoxx volume to minimum
3. Start the Bluetooth service on your mobile device
4. Click on "DiamondBoxx XL2"
TIP: We suggest setting the volume control on your mobile device to
MAX and using the volume control on the DiamondBoxx to set the
volume to your desired listening level for best performance.
The Bluetooth range should be about 50 feet in line of sight. Putting
things between (like human bodies) will decrease this.
If you are having trouble connecting:
1. Make sure nothing else / nobody else is connected to it.
2. Power off DiamondBoxx for 30 seconds, then power on and look
for DiamondBoxx XL2 to pop up on your mobile device, tap to
connect.
3. Make sure you are within 50 feet line of sight, closer if objects,
walls, human bodies etc. are between the DiamondBoxx and the

Aux In Jack - Front Panel
The front panel AUX IN jack has ZERO LATENCY and can be
connected to just about anything with an audio output. This
would include:
l Laptops, Tablets and Phones
l Computers, gaming consoles, and projectors
l Audio Mixers
If the item you want to plug in doesn't have the right jack, your
local electronics store will have an adapter.
Note: If using the DiamondBoxx as an audio amplifier for a video
source, (watching movies and etc.) the AUX jack should be used
as it will avoid the delay caused by wireless audio transmission)
The USB POWER Jack
We added this feature because we thought ahead. If you are
at the beach or somewhere else listening to your music and
your phone battery is running low, no worries. The Diamond-
Boxx has a built in 2.1A USB power connection. It will charge
your phone or tablet from wherever you happen to be. Just
plug in your phone charger cable and turn the DiamondBoxx
on.

Rear Panel
This is where you plug in the included charger to recharge your
DiamondBoxx. USE ONLY THE INCLUDED CHARGER OR MAJOR
DAMAGE CAN OCCUR, THE MODEL XL and XL2 USE A 7A 4 PIN
CHARGER THAT IS DIFFERENT THAN MODEL M AND MODEL L
CHARGERS.
The OUT jack is for connecting to the IN jack of another
DiamondBoxx Model XL2, XL, L2, or L. They can be daisy-chained
in this manner an indefinite number of times to create a giant
sound system! If two Model XLs are to be used in a LEFT and
RIGHT stereo setup, use the TWS wireless function. If the ¼” jack
method is used both DiamondBoxx will play stereo information
themselves.
You can combine the TWS function with the ¼” jack linking
method as well if you have multiple “left” DiamondBoxx and
multiple “right” DiamondBoxx. If this is something you wish to do
make the Left and Right pair of DiamondBoxx using the TWS
function as outlined on page 4, then connect additional “left”
DiamondBoxx together using the rear ¼” jacks and ¼” stereo
cable (sometimes called TRS or balanced cable, available on
DiamondBoxx.com or a musical instrument store) Repeat the
wired linking for the “right” speakers. No wire is needed between
the left and right sides.
Getting crazy with it
If you really want to get crazy we suggest purchasing some
DiamondBoxx replacement small feet from DiamondBoxx.com to
screw into the sides of the DiamondBoxx so that they can be
positioned vertically instead of horizontally. (These are the feet
for the Model M and L, L2) Then stack the left and right
DiamondBoxxes in towers with the tweeters to the outsides and
place all DiamondBoxxes in SP Mode. This will create a “Line-Ar-
ray” system which will give you the loudest possible output,
especially at a distance.

The Handle
The handle was designed to make the DiamondBoxx portable
while feeling good in your hand. It can lock in 2 positions. As with
anything leather, it is a little stiff at first. A good pull on it should
lock it in the upright position. Pressing down on it in the middle
and on the ends should lay it flat again.
The DiamondBoxx Enclosure
The enclosure is made from Medium Density Fiberboard (MDF).
This is what most great sounding are made from. No plastic. As
such, it is difficult to manfacuture any crazy curvy shapes as pos-
sible with, but it SOUNDS better. Isn’t that the point?
The DiamondBoxx enclosure is sealed using DURATEX speaker
coating that will provide years of protection.
If it should ever get damaged beyond your liking by knocking it
into things, dropping it, scratching it and such, all is not lost. You
can send it to us in the ORIGINAL PACKING or equivalent and we
can replace the enclosure for a small fee.
As they are all hand built and rolled it is normal for there to be
slight inconsistencies in the finish. Consider them like beauty
marks, specific to your DiamondBoxx.
To clean just wipe down with a water dampened cloth.
