HF210 Bluetooth Digital Decoding Amplifier All-in-one Manual

 

Introduction

• This is a digital decoding power amplifier all-in-one machine, supports Bluetooth reception Qualcomm core version QC3008 Bluetooth 5.0, supports APTX-LL.
• Original TPA3116 chip: output power up to 2*50W+1*100W, low heat, low distortion, can easily drive 3-6 inch speakers for home audio systems.
• Original TI5532 digital audio amplifier: dual-channel low-noise high-speed audio operational amplifier Texas Instruments 5532 can be disassembled and replaced by itself. The resistors are selected by precision patches.
• PCB adopts 1.6mm thick double-sided board, 2.0 oz copper thickness, and full tinning process to ensure good passing performance of large and small currents.
• Special inductor for digital power amplifier: Red-gray ring audio dedicated high-current inductor, the sound is more clean and delicate, with clear levels. Independent treble and bass control to meet different listening styles.
• Fully enclosed dust-proof potentiometer: performance is more stable, more durable than ordinary potentiometer.
• All aluminum alloy shell: surface oxidation treatment, fine wire drawing process, no fading, no word loss, natural and minimalist design, simple operation experience.
