Douk Audio A100 TPA3255 300W Dual Channel Digital Amplifier for Home Audio and Subwoofers

About this item

• 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.
• 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.
• Key Specifications for Accurately Replicating Sound Quality: The Douk Audio A100 amplifier features advanced technology throughout. It delivers a rated power of 240W@4Ω in stereo and 315W@4Ω in mono. It boasts an impressively low THD of 0.002%, a SNR of 115dB, and a SINAD of 94dB, surpassing comparable models 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.
• 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.
