L3 Bluetooth Boombox
Owner’s Manual

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 the 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!
DO NOT THROW AWAY YOUR PACKAGING IT IS REQUIRED IN CASE 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 Switch

This controls the power of the DiamondBoxx. Push into power on.

The TWS Switch

This is used for True Wireless Stereo control. This is for wireless linking of two 2 nd rd or 3 gen DiamondBoxx in a Main/Secondary, LEFT AND RIGHT configuration.
To Wirelessly connect two compatible 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 the Main
   DiamondBoxx until the LED under the letter “M” blinks rapidly, then the release button.

5. Press and hold the TWS button on the Secondary DiamondBoxx until the LED under the letter “S” blinks rapidly, then the release the 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 releases the 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.

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 the charge level on the White LED bar graph  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 the 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.

The Volume Knob

Self-explanatory. Tip: We suggest if the music source is 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 affects 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.

The Treble knob provides about 10 decibels of range from min to max. It affects 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. The 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.

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 the 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 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.

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 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 the 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 DURATEC speaker coating that will provide years of protection and provides a barrier to 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.

Happy Listening!
