Product 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.
Customer Reviews
Ich benutze diesen Verstärker in Kombination mit einem Phono-PreAmp und einem recht hochwertigen Plattenspieler und in diesem Setup funktioniert der Verstärker richtig gut.Testweise hab ich sogar einen 2.1 Betrieb gestartet und dieser war in Ordnung, entspricht aber nicht dem, was Vinyl hergeben kann, daher läuft das Setup nun wieder mit zwei älteren, bewährten Studiomonitoren von Canton und meine Scheiben klangen schon lange nicht mehr so gut.Die Verarbeitung ist einwandfrei, durch die Kühlrippen hatte er auch keine Probleme, als es noch wesentlich wärmer gewesen ist und das Netzteil ist gut, erzeugt so gut wie keine Interferenzen, was sicherlich an der Größe der Komponenten liegt, anders als bei kleineren Steckernetzteilen.Für ein Setup wie meines auf jeden Fall eine gute Wahl und Empfehlung !
