The B3 for Business: One Box, Every Space

The blafili B3 is the commercial side of the blafili lineup: a Bluetooth audio receiver built for classrooms, boardrooms, hospitality spaces and studios that still run on wired speakers. A Qualcomm QCC5125 chip drives high-fidelity audio out of balanced XLR, RCA, COAXIAL and OPTICAL outputs — one small box lets any Bluetooth phone, tablet or laptop take over a professional sound system.

Where blafili B3 Makes a Difference

The B3 is built around a Qualcomm QCC5125 Bluetooth chip feeding an ESS ES9018K2M DAC — the same pairing trusted by desktop hi-fi. Our own PCB and interface module fold all of it into a palm-sized shield, so a full sound system hides behind any lectern, screen or counter.

Product Features

Wired systems limit mobility; incompatible AV setups. Any phone, tablet or laptop takes over the installed speakers — teachers and presenters move freely, and projectors and powered speakers just work.
Audio lag in large spaces; complex installations. Bluetooth 5.1 with aptX LL low latency (<40 ms) and a 100 ft range — one box covers the room, and adding speakers stays simple.
Clunky device switching; OS conflicts. One tap switches the link across phones, tablets and laptops — Windows, macOS, Android and iOS all supported.

Built for Commercial Spaces

Classrooms & training rooms teachers and presenters move freely while the lesson keeps playing through the installed speakers — no cables across the floor, no AV cart.
Boardrooms & offices one-tap switching between laptops and phones ends the "which cable is this" meeting opener; audio stays in sync for calls and video.
Bars, cafés & restaurants staff stream the house playlist from any phone at the counter and control it from up to 100ft away — the wired PA stays exactly as installed.
Studios & pro installations the balanced XLR output feeds mixers and powered monitors cleanly, and aptX HD keeps reference material sounding the way it was mastered.

FAQ

What is the blafili B3 used for?

It lets you add wireless stereo Bluetooth audio reception to any professional audio system. Once you pair your Bluetooth device to the blafili B3, you can send your device’s audio signal out of the blafili B3’s balanced XLR, unbalanced RCA, COAXIAL or OPTICAL outputs into a playback system of your choice.

How far is the Bluetooth range of the blafili B3?

The blafili B3 can play audio from an audio device that sends its signal over a Bluetooth connection (e.g., smartphones, tablet computers, etc.). The blafili B3 uses Bluetooth 5.1 + Enhanced Data Rate (EDR) and has a range of up to 100 feet (30 meters).

How do you pair with the blafili B3?

1. If blafili B3 is off, use the unincluded power adapter to connect its power input to your power source. 2. Make sure your desired Bluetooth device has its Bluetooth connectivity on and is within range. blafili B3 will automatically try to pair with the last-paired Bluetooth device, if any. If you are using that Bluetooth device again, you can start playing audio immediately. If you want to use a different Bluetooth device, continue to Step 3. 3. Un-pair connected Bluetooth device: Double press the MFB button. 4. On your Bluetooth device, enter its Bluetooth settings menu, and select blafili. Note: (Some older Bluetooth devices may require you to enter a PIN. If this is the case, enter 0000 as the PIN.) 5. On your Bluetooth device, start playing audio. To adjust your volume level, we recommend setting the volume control of each of your devices in the following order: your Bluetooth device, your mixer (if any — its input channel levels, then its main output level), your loudspeakers. Set each volume level as high as possible without creating distortion or any “clipping” of the sound. (Important: blafili B3 will not receive audio from a phone call. While using it, we recommend disabling your cellular connection, if possible).

How do you unpair the blafili B3?

To unpair your Bluetooth device from blafili B3, do one of the following: enter your Bluetooth device’s Bluetooth settings menu and disconnect from blafili, or double press the MFB button to un-pair the connected Bluetooth device. blafili B3 will unpair from your Bluetooth device and be available to pair to another one.

What type of audio equipment will the blafili B3 work with?

Once you pair your Bluetooth device to blafili B3, you can send outputs to your mixer, loudspeakers, or amplification system.

What can prevent the Bluetooth from connecting?

Using the blafili B3 near a microwave oven can interfere with the reception. If the blafili B3 is paired with a different Bluetooth device, other Bluetooth devices cannot pair to it. You must unpair (“disconnect”) the current Bluetooth device from blafili B3 to make it available to others.

Does the B3 work with projector and classroom AV systems?

Yes — teachers and presenters plug the B3 into the system’s free line input (XLR, RCA, optical or coaxial), pair the room’s phone or laptop once, and move freely while streaming. See the scenarios above or the business solutions page for the full setup.
