The B1 Bluetooth Receiver utilizes the AKM AK4396A DAC, widely known for its low noise and high fidelity. B1 is essentially an upsampling 24-bit Bluetooth DAC and will pad all bit depths internally to 24-bits, thus achieving a higher signal-to-noise ratio. Due to the AK4396A’s high signal-to-noise specs, the fact that digital signal is converted (upsampled) to 24-bits and the added benefit of triple redundancy power source conversion and filtering, the B1 presents impressive low noise and low distortion characteristics with a noticeable improvement over other Bluetooth devices.
Most Bluetooth implementations have very limited range, usually within just one room. But with careful signal management circuitry and antenna tuning, we offer a superior solution that will reach more than one room with no degradation in audio quality.
High quality Bluetooth audio
The B1 features aptX coding which is an advanced Bluetooth audio codec that provides much higher-quality sound than previous versions. The B1 is backwards-compatible with all previous Bluetooth implementations so you can wirelessly stream music from any device and still enjoy outstanding sound.
B1 also functions as a wireless audio bridge from your device to your favorite DAC or preamp. Use the internal DAC with RCA analog outputs or connect the optical output into another DAC.
