A100 TPA3255 300 watts x2 Digital Power Amplifier, Stereo/Mono Channel SUB Audio Amp for Home Speakers/Subwoofers, Black, SUC-A100

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@4 in stereo and 315W@4 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
