Digital Power Amplifier for Home Speakers/Subwoofers - Stereo/Mono Channel, 300W x2 - Douk Audio A100 TPA3255

About this item

• 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.
• TOP LEVEL Parameters to Truly Reproduce the Sound: Douk Audio A100 amplifier adopts the most cutting-edge technology in all aspects. The rated power is up to 240W@4Ω in stereo and 315W@4Ω in mono, it incredibly achieves a THD as low as 0.002%, a SNR of 115dB and a SINAD of 94dB on the premise of its powerful features and strong flexibility, far ahead of other similar ones.
• Innovative and Strong Playability: With MONO/STEREO and BASS/FLAT switch, A100 supports four working modes to adapt flexibly to diverse scenarios. Additional AUX output makes it easy to drive all subwoofers and speakers and build all multi-channels systems (1.0/2.0/2.1/2.2/4.0/5.1...). A100 also features Super Bass and SW-FREQ knobs to freely adjust the bass gain and cutoff frequency to achieve a more shocking bass experience.
• PFFB Design and Optimal 4-layer PCB Layout: Utilizes post-filter feedback technology (PFFB) to effectively address typical load dependency challenges associated with Class-D amplifiers, resulting in a marked reduction in distortion while improving linearity, frequency response, sound clarity, and overall system efficiency. Additionally, it features a 4-layer high-quality immersion gold PCB, which improves signal integrity and enhances performance as well as resistance to interference, leading to exceptional sound quality.
