blafili B3 Professional XLR Bluetooth 5.1 Receiver – LDAC & ESS DAC, Multi-Output for DJ, PA & Studio

Meet the blafili B3, a professional Bluetooth receiver designed to bring wireless sound to powered speakers, mixers, and DACs. It streams from your phone or computer with high fidelity, while remaining a receiver rather than a transmitter or amplifier. Note: it cannot drive passive speakers directly.

Key capabilities

• Supports LDAC, aptX HD, aptX Low Latency, aptX, SBC and AAC codecs for high quality wireless audio.
• Built around Qualcomm QCC5125 and ESS ES9018K2M DAC for low distortion and wide dynamic range.

Versatile connections

All active outputs are live simultaneously, offering RCA, optical, coaxial, and XLR options to fit your gear. Note: Toslink is output only and there is no optical input.

• Connect to hi fi receivers, preamps, amplifiers, DACs, or powered speakers with ease.
• RCA and optical cables are supported; USB and Bluetooth inputs provide flexible sources.

• Silent pairing and no start-up beeps keep listening uncluttered.
• Long range up to 33 m, with a removable RP-SMA antenna to help extend reach.
• 1.3 inch display with protective acrylic window provides quick status checks.

Practical use and setup

Power is supplied via USB C; you can pair from a phone or use a USB DAC mode with a computer. Custom broadcast names are available for branding and optional passcodes for added control.

• USB DAC mode supports up to 16 bit 48 kHz when used with a computer.
• The Bluetooth input takes precedence when both Bluetooth and USB sources are connected.
