Description

Product Overview: 
The BRZHIFI BL50B is a high-fidelity 2-channel Class-D digital amplifier engineered for audiophiles who require lossless wireless performance. Built on the Qualcomm QCC3034 platform, it supports APTX-HD 24-bit transmission, delivering studio-grade audio over Bluetooth. The internal architecture features an independent TI PCM5102A DAC to ensure superior dynamic range and low distortion, all housed in a precision-machined, heat-dissipating aluminium alloy chassis.

Key Technical Features:
-Lossless Bluetooth Integration: Equipped with the QCC3034 chipset, providing APTX-HD 24-bit lossless transmission for high-resolution wireless audio that rivals wired connections
-Independent DAC Decoding: Features the Texas Instruments PCM5102A 24-bit DAC, offering a 112dB dynamic range and a direct 2.1V RMS output for clean, burr-free high frequencies
-Precision Tone Customization: High-quality front-panel potentiometers allow for independent Bass and Treble adjustment alongside a smooth-taper Master Volume control
-High-Efficiency Power Stage: Utilizes Class-D architecture to drive 4–8Ω speakers efficiently, maintaining a low static power consumption of only 5W
-Interference-Shielded Chassis: The all-aluminium alloy body provides natural cooling and protection against electromagnetic interference (EMI) for a cleaner signal path
