Douk Audio A100 TPA3255 Digital Power Amplifier Mono/Stereo Bass Audio Amp 300W Item description Introduction The A100 is a mighty home audio amplifier designed by Douk Audio, with mono/stereo and bass/full-frequency switch. Adopting TI’s TPA3255 power chip, max output can reach 300W to effortlessly drive all home passive speakers and subwoofers. Besides PFFB technology, A100 is equipped with exclusive patented heat dissipation technology which makes TPA3255 reach its maximum potential, letting you immerse yourself in the high-fidelity audio world. Features Exclusive Patented for Heat Dissipation: The A100 breaks the traditional heat dissipation techniques, discards the conventional design of built-in heat sinks and body-edge ventilation holes, ingeniously integrating the heat sink seamlessly with the body of A100 itself. While maintaining the A100’s stylish and eye-catching looking, significantly expands the heat sink groove area and achieves more direct and efficient airflow contact to make great improvement in heat dissipation efficiency and ensures the A100’s stability and performance during continuous work. Innovative and Versatile Four Working Modes: A100 with mono/stereo and bass/full-frequency switch, that means it supports four combinations of working modes to adapt flexibly to your diverse usage scenarios and allow seamless mode switching. Bridged mono mode provides more power for your system, pairing two A100s to create a powerful audio system, significantly enhancing your listening experience. TI TPA3255 and PFFB design: Features the TPA3255 class D amp chip, default comes with DC 48V/5A power adapter, the max output power of each channel reaches 120W in stereo mode and 315W in mono mode. Adopts post-filter feedback technology (PFFB), significantly reduces distortion, enhances linearity and frequency response, and improves sound purity and system efficiency, it also utilizes four-layer premium immersion gold PCB, Japanese Rubycon, ELNA, German WIMA capacitors and high-precision potentiometer etc. for exceptional audio quality. Richer Connectivity and Adjustment: Besides mono/stereo speaker output, A100 also supports 3.5mm AUX output with amplification and independent volume control, another amplifier, active speaker or subwoofer can be connected to build 2.1 or multi-channel home theater systems. A100 also features Super Bass and SW-FREQ knobs to freely adjust the bass gain and cutoff frequency to achieve more shocking bass effects. Swappable Op-amps and More Details: default 2PCS pluggable NE5532, easily to be replaced by 8-pin dual op-amps like MUSES02, OPA2604, OPA2134PA, OP249, AD827, LME49720HA, etc. to tailor your own sound styles. All-Aluminum alloy chassis, compact yet powerful; bigger pure copper banana speaker terminals to transmit larger current safely; its unique shape makes it easy to be placed horizontally or vertically to adapt to different spaces. 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.
