High-Quality Bluetooth Audio
- Extended-range wireless: Most Bluetooth implementations have very limited range, typically within just one room. But with careful signal management circuitry and antenna tuning, we offer a superior solution that has up to 3 times the range of standard Bluetooth for multi-room use, with no degradation in audio quality.
- 24-bit DAC: The HD4 Bluetooth receiver and USB input both utilize the PCM 5102 DAC, widely known for its low noise and high fidelity. The PCM 5102 is used as an upsampling DAC and will pad all bit depths to 24-bit, achieving a higher signal-to-noise ratio and lower noise floor. Due to the high signal-to-noise specs of the PCM 5102, the fact that digital signal is upsampled to 24-bit as well as the added benefit of onboard triple redundancy power source conversion and filtering the HD4 Bluetooth implementation presents impressive low noise and low distortion characteristics with a noticeable improvement over other Bluetooth devices.
