DiamondBoxx M3 User manual

MODEL M3

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 200 Watt RMS (400W max), class A/B
high fidelity amplifier in a bi-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 when cared for properly
should provide you with years of listening pleasure.
Happy Listening!

Battery Life
Fully charged the DiamondBoxx M3-115Wh will play 4-20 hours or 8-40
hours with M3 231Wh battery. Battery life depends on volume level
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.
The Diamond
Besides its looks, the 2 Carat 8mm 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 30% charged.
If your Diamond turns RED this means your battery is less than 30%
and getting low.
NOTE: If playing while charging, the charger LED might not ever turn
green as some charging power will be used to keep the battery fully
charged while playing). The battery can be charged at any time, with
the DiamondBoxx playing music or not.
If audio quits playing and the Diamond is RED mixed with a flashing
PINK/BLUE color this means the battery is completely discharged and
music has been muted to protect it from further discharge. If this
happens please plug charger into DiamondBoxx and let charge for a
few minutes before expecting the DiamondBoxx to unmute and start
playing music again.
NOTE:The DiamondBoxx can recharge while in use.

The Power Button
This controls the power to the DiamondBoxx.
Push in to switch power on.
Push again to switch DiamondBoxx off.
The Knobs
Your DiamondBoxx should have been delivered
along with 3 more sets of knobs in other colors.
This provides you with a way to customize your
DiamondBoxx the way you want it.
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.
Bass Knob
This 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 limit-
ing may occur.
Treble Knob
This 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 Change the Knobs
1. Turn knob to minimum position. Indicator line should be some-
where 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

TWS (True Wireless Stereo) Button
This controls the TWS (True Wireless Stereo)
system on the DiamondBoxx. This is used to con-
nect two DiamondBoxx 2nd generation or later
together wirelessly in a split stereo pair for an
amazing, headphone like stereo experience.
To USE TWS System
1. Start with both DiamondBoxxes powered OFF.
2. Power up one of the DiamondBoxx, pair your Blue-
tooth device with it. Start streaming some music to it.
3. Power up the 2nd DiamondBoxx
4. Now go back to the 1st DiamondBoxx, press and
hold the TWS button until the Diamond starts flashing
BLUE then release button. This will set this Diamond-
Boxx to “MAIN” speaker which will receive and play
LEFT audio only.
5. Now go to the 2nd DiamondBoxx, press and hold
the TWS button until the Diamond starts flashing
GREEN then release button. This will set this
DiamondBoxx to “SECONDARY” speaker which will
receive and play RIGHT audio only.
6. Wait for up to 2 minutes for the DiamondBoxxes to
configure themselves and form a secure connection.
NOTE: The maximum distance between the MAIN and
SECONDARY DiamondBoxxes should be less than 50
feet with a unobstructed path of each other. If
obstructions like walls and human bodies exist
between the two DiamondBoxxes the max range
could be shorter than 50 feet.
Tip: Raising the DiamondBoxxes off the ground/floor
may help extend the range.
8. If the TWS linking procedure didn’t work, press and
hold the TWS button until the Diamond turns RED,
this will CLEAR the TWS memory. Do this to both
units and start procedure again from Step 1.

The Bluetooth
To connect your Bluetooth device:
1. Turn on the DiamondBoxx
2. Start the Bluetooth service on your mobile device
3. Click on "DiamondBoxx M3"
The Bluetooth range should be near 100 feet if unobstructed. Putting
things between like human bodies and walls will decrease this. Lift-
ing the DiamondBoxx off the floor or ground will usually increase the
range.
If having trouble connecting, first check that another device isn’t
already connected, this is usually the reason for connection troubles.
If not solved power the DiamondBoxx off for 60 seconds. Open the
Bluetooth devices list on the device you wish to connect.
If DiamondBoxx M3 is already there, delete it. Now power on the
DiamondBoxx and watch for DiamondBoxx M3 to pop-up on the

Rear Panel Jacks
Charger
This is where you plug in the included charger to
recharge your DiamondBoxx. 16.8V 2A DC Only
5.5mm x 2.1mm USE ONLY THE INCLUDED CHAR-
GER OR MAJOR DAMAGE CAN OCCUR. Replace-
ment chargers are available at DiamondBoxx.com.
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
l Tablets
l Phones
l Projectors
l Computers
l Gaming consoles
l Audio Mixers / Musical Instruments
If the item you want to plug in doesn't have the right
jack, your local electronics store will have an adapter.
AUX 2
This is a ZERO LATENCY stereo 3.5mm input jack that MIXES.
While the AUX on the front panel overrides the Bluetooth, this AUX
2 input on the rear panel MIXES with the Bluetooth or the AUX on
the front panel for a various reasons including wanting to use a
microphone or musical instrument mixed with audio from Blue-
tooth or the front AUX jack.
OUTPUT
This is a stereo 3.5mm jack that outputs the same signal that is
being played. The audio signal that comes out here is volume
knob dependent, but Bass and Treble tone control independent so
they have no effect on the audio on this jack. While this might
have been useful when a subwoofer is connected, it is a bad thing

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.
