DiamondBoxx SUB8.2 User manual

SUB8.2

Congratulations on your purchase of the first battery powered
rechargeable wireless Bluetooth SUBWOOFER! Our design goal was to build
something that could add depth to the first 2 octaves of any other portable
speaker that has an AUX IN jack. EVEN YOUR CAR!! As well as being
completely portable, without need for nearby electricity. We used the
highest quality materials for each intended purpose.
We used the highest quality materials for each intended purpose.
Wood Aluminum Lithium Leather Stainless Steel
Put together along with a 200 Watt RMS (400W Max)Class A/B high fidelity
4 channel amplifier with user adjustable 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!

DO NOT THROW AWAY YOUR PACKAGING it is required incase of
return for WARRANTY ISSUES or REFUND. If it’s too bulky, cut the
tape on the bottom and fold it flat. Store foam endcaps next to it.

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
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.
Bass EQ Knob
The Bass EQ knob provides about 14 decibels of range from min to max. It effects
frequencies from 20Hz to 80Hz. Centered at 45Hx these frequencies give music size
and realism. Adjust to taste. Note: If very bass heavy music is used along with the
bass knobs at max, some real-time volume limiting and/or distortion may occur,
reduce bass controls or volume settings slightly.
The Xover control
The Xover knob adjusts the range of frequencies the SUB8.2 will play. More
exactly it determines the highest frequency the SUB8.2 will play before starting to
filter it out. The range is from 50Hz to 150Hz. If placed at 50Hz the SUB8.2 will
play frequencies from 20Hz –50Hz. If set at 150Hz it will play frequencies from
20Hz –150Hz. The idea here is to set it to the frequency that your other speaker
plays down to so that the combination of the SUB8.2 and your other speaker
sound good together. In the end, adjust to taste. 70Hz is a good starting point.
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.

Battery Life / Battery Level Meter
When you first power up the DiamondBoxx the White LED indicators will illuminate
as a bar graph showing the % of battery charge. After a full recharge, the
DiamondBoxx will play 6 –40 hours depending 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. (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 startup sequence and display charge level on the
White LED 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, please charge ASAP.

TWS (True Wireless Stereo) Button
This is used for True Wireless Stereo control. This is for
wireless linking of two 2nd or 3rd gen DiamondBoxx or two
DiamondBoxx SUB8.2 in a Main/Secondary LEFT and RIGHT
configuration or a Mono/Mono configuration.
To Wirelessly connect two compatiable DiamondBoxx perform the following.
1. Power on the DiamondBoxx that will be the MAIN.
2. Connect the Bluetooth device to it
3. Power on the DiamondBoxx that will be SECONDARY
4. Press and hold the TWS button on MAIN DiamondBoxx until the LED next to
the letter “M” blinks rapidly, then release button.
5. Press and hold the TWS button on the Secondary DiamondBoxx until the LED
next to 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 next to the
letter “C” flashes rapidly and then release button. This should clear the TWS
system, now start from step 1 again.
8. Note the 2 DiamondBoxxes must be less than 30 feet from each other
typically.
To switch between Left/Right Stereo and Mono/Mono operation while in TWS
mode - Press and hold TWS button on the MAIN speaker until the LED next to
the letter “X” flashes, immediately release.

The Rear Panel
This is where you plug in the included charger to recharge your DiamondBoxx. USE
ONLY THE INCLUDED CHARGER (16.8 VDC, 2 Amps) OR MAJOR DAMAGE CAN
OCCUR.
The FULL and 80Hz HP jack can be used to connect to additional DiamondBoxx
subwoofers or other DiamondBoxx products or any other speaker with an AUX IN
jack. We recommend if connecting a Model M, M3, 40W, 40TWS, or any other
small size Bluetooth speaker to the subwoofer to use the 80Hz HP OUTPUT jack.
This jack is useful to remove the bass from the speaker connected to it and let the
SUB8.2 handle the low notes. Most smaller speaker systems will be able to play
louder when they don’t have to try to reproduce the low notes, leave those for the
SUB8.2
The rear panel INPUT 1 jack and INPUT 2 jack can be connected to just about
anything with an audio output. This would include:
Output from another DiamondBoxx
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 or
music store will have an adapter.
These two jacks are mixed together so multiple audio sources can be played at
once or mixed together, they can be used simultaneously.
These connections can also be used to link multiple DiamondBoxxes together. 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.
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 SUB8.2"
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.
If you are having trouble with “DiamondBoxx SUB8.2” 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
SUB8.2. 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 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 high quality MDF wood. This is what most great
sounding speakers use to make them sound good. No plastic. As such, it may not
be as rugged as plastic when it comes to cosmetic blemishes, but it SOUNDS much
better. 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
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.
