Douk Audio A100 HIFI Mono/Stereo Power Amplifier TPA3255 Digital Audio Amp 300W Item description Introduction The A100 is a mighty home audio amplifier designed by Douk Audio with top-level parameters and epoch-making innovation. Adopt exclusive heat dissipation patent, optimal circuit layout and PFFB design, with the help of custom-made 48V power adapter to maximize the actual output power of TPA3255. With MONO/STEREO and BASS/FLAT switch and AUX output, it is easy to drive all subwoofers and speakers and build all multi-channels systems, letting you immerse yourself in the high-fidelity audio world.Features 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. 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. 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: 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. 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. Warm tips: 1. The kind of AUX output signal (bass or full-frequency) is determined by the input signal, and the AUX output with amplification. 2. The super bass and SW-FREQ knobs are only valid in the SUB mode, invalid if you select FLAT mode. 3. Before use, please make sure that you have selected correct working modes, mono or stereo, sub or flat, or else the A100 won’t work normally.
