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 6 channel Class A/B hi-fidelity
300 Watt RMS (600W Max amplifier in a tri-amped
arrangement with active crossovers for the best sound
possible in the lightest package with the longest battery
life.
Your DiamondBoxx was hand-built and cared for
properly should provide you with years of listening
pleasure.
Ok! Let's Play!

This controls the power to the DiamondBoxx. Push in to
power on.
The TWS Switch
This is used for True Wireless Stereo control. This is for
wireless linking of two 2nd or 3rd gen DiamondBoxx in a
Main/Secondary, LEFT AND RIGHT configuration.
To Wirelessly connect two compatiable DiamondBoxx

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 transmitting 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.

than 30 feet from each other typically.

Battery Life / Battery Level Meter
When you first power up the DiamondBoxx the White
LED indicators under the DiamondBoxx logo will
illuminate as a bar graph showing the % of battery
charge. After a full recharge, the DiamondBoxx Model
L3 will play up to 40 hours depending on volume level
(around 8 hours max volume) and music type. 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 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.
Remember to check the battery level just switch the
DiamondBoxx Power Switch OFF and then back ON to
reboot and display charge level on the White LED
bargraph display.

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
all colors so it may look different from different angles)
the battery is more than 25% Charged.
If your diamond turns If it turns Red you are at less
than 25%. (It may blink between white and red a bit
with music playing, this is normal and means your
battery is around 25%)
If the diamond is red blinking pink-purple this means
the battery is too low to operate the DiamondBoxx,
please charge ASAP.
The AUX IN jacks
The front panel AUX IN jack can and the rear panel AUX
2 jack be connected to just about anything with an
audio output. This would include:
Laptops, Tablets and Phones
Computers, gaming consoles, and projectors
Audio Mixers
If the item you want to plug in doesn't have the right
jack, your local electronics store will have an adapter.
These two jacks are mixed together so multiple audio
sources can be played at once or mixed together.

7
The Volume Knob
Self explanatory. Tip: We suggest if the music source
being connected to the DiamondBoxx also has a volume
control, leave that device's control at MAX volume. Use
the DiamondBoxx volume control to control the level.
This will provide the cleanest sound without Bluetooth
or other random noise getting into the sound. IF THE
DIAMONDBOXX WILL NOT LIGHT UP ALL OF THE WHITE
LEDS WHILE PLAYING MUSIC WITH THE VOLUME KNOB
TURNED TO MAX PLEASE CHECK THE VOLUME LEVEL
AND THE VOLUME LIMITER SETTINGS IN YOUR
BLUETOOTH DEVICE SETTING AND THE APP THAT IS
BEING USED TO PLAY MUSIC. Many apps and phones
have this volume limiter enabled by default, turn it off
to feel the real power of the DiamondBoxx.
The Bass and Treble controls
The Bass knob provides about 10 decibels of range from
min to max. It effects frequencies from 20Hz to 100Hz
or so, gradually losing its effect with higher frequencies.
Adjust to taste. Note: If very bass heavy music is used
along with the bass knob at max, some real-time
volume limiting may occur and possible modulation
distortion, reduce bass or volume setting slightly.

8
The Treble knob provides about 10 decibels of range
from min to max. It effects frequencies from 2,000Hz to
20,000 Hz thus adding some sizzle to music that needs it
or reducing the brightness of music that is overly bright.
Adjust to taste.
To replace the knobs:
1. Turn knobs to minimum position. Indicator line
should be somewhere between 6 and 7 o’clock
when set to minimum
2. Pull the knob straight off without twisting
3. Check to make sure the knob shaft is still at
minimum position, Press the new knob onto the
shaft with the indicator line between 6 and 7
o’clock
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.

9
The 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 output jack can be used to connect to
DiamondBoxx subwoofers or other DiamondBoxx
products.
The input jack is a 2nd input that is mixed with the front
panel AUX jack, they can be used simultaneously.
These connections can also be used to link multiple
DiamondBoxxes together, or to add a DiamondBoxx
Subwoofer. By plugging a 3.5mm Stereo cable into the
OUT jack of one DiamondBoxx and into the IN jack of
another DiamondBoxx you will have double the sound.
The first DiamondBoxx will control the volume for both
DiamondBoxxes. You can continue to daisy-chain them
like this up to concert sound levels! Tip:Turn power off
to all DiamondBoxxes involved during this process.
Then turn on the "Main" DiamondBoxx before turning
on the next one.

10
The Rear Panel (cont.)
Bluetooth Tip: If using Bluetooth, turn the "Main"
DiamondBoxx on first, connect your Bluetooth device,
then continue to turn on any other DiamondBoxxes.
The cable required is a standard STEREO 3.5mm cable
(sometimes called TRS) available at guitar or musical
instrument store, or from our website or an electronics
supply store, or Amazon.
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 L3"
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. Also check phone
or other device’s settings for volume and volume
limiter.
The Bluetooth range should be about 50 feet in line of
sight. Putting things between (like human bodies) will
decrease this.

11
The Bluetooth (cont.)
If you are having trouble with “DiamondBoxx L3”
appearing in your Bluetooth device list power OFF the
DiamondBoxx for about 20 seconds. In the meanwhile
turn off Bluetooth services on your wireless device.
Then turn back on the Bluetooth services on your
wireless device, and the power ON the DiamondBoxx
L3. It should immediately pop up on the list. If this
doesn’t work delete any other DiamondBoxx that might
be on your list and repeat above procedure.
The DiamondBoxx Enclosure
The enclosure is made from high quality MDF wood.
This is what most great sounding speakers use to make
them sound good. Not plastic. The DiamondBoxx
enclosure is coated with DURATEX speaker coating that
will provide years of protection and provides a barrier
for water. If it should ever get damaged beyond your
liking by knocking it into things, dropping it, scratching it
etc; not all is 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
the finish coated by hand 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.
