DoukAudio TPA3255 Digital Power Amplifier, 300 watts x2 Stereo/Mono Channel SUB Amp for Home Speakers/Subwoofers (A100)

Product description

• Custom-made 48V Power Adapter and High-end Components Limited to heat dissipation and its power adapter, most TPA3255 amplifiers cannot output ideal power. Douk Audio also specially tailored a high-efficiency 48V power adapter for A100 to perfectly maximize TPA3255's performance. It also uses Japanese Rubycon, ELNA, German WIMA capacitors and high-precision potentiometer etc. to get exceptional audio quality.
• Exclusive Heat Dissipation Patent Integrates the heat sink seamlessly with its body and significantly expands the cooling area to achieve more direct and efficient airflow contact, allowing heat to be effectively dissipated through the casing and unleash the performance of TPA3255. The case won't be obviously warm even at continuous high power output compared with other similar amplifiers on the market.
• PFFB Design and Optimal 4-layer PCB Layout Adopts post-filter feedback technology (PFFB), effectively overcomes the common load dependency issues of Class-D amplifiers, significantly reduces distortion and enhances linearity, frequency response, sound purity and system efficiency. It also utilizes 4-layer premium immersion gold PCB, boosts signal stability and enhances performance and interference resistance for superior sound output.
