Nobsound NS-21G Mono Block Amplifier 100W High Efficiency with TPA3116 Chip Compact HiFi Subwoofer Amplifier Compatible with Bass Shaker RCA/AUX Input Adjustable Low Frequency Desktop Installation

$61.82

  • High Density 100W Power & Clear Bass Playback > Mono Channel Amplifier with 100W output in a small housing Uses TI TPA3116 Class D chip to achieve more than 85% energy conversion efficiency. It plays powerful low frequencies perfect for passive subwoofer and bass shakers. > Technical Rations: Supports 4-8Ω speaker load, 0.04% low distortion (THD+N) ensures distortion-free bass effect in home theater and gaming environments. The heat dissipation design of the metal housing ensures stable operation even after long continuous use. The compact design (90x105x30mm) can be installed around a desktop PC or AV rack space while providing deep bass that physically experience explosive movie sounds and music baselines
  • Dual Input & Multi-Device Connectivity > Equipped with RCA/3.5mm AUX Dual Input Can be directly connected to a variety of audio sources such as TVs, PCs, smartphones, game consoles, etc. > EXTENDED PRACTICALITY: Simple design without input-switch, so you only need to connect one side when using it (risk of cross talk at the same time). When combined with the included 19V power adapter (0.2 x 0.1 inch (5.5 x 2.5 mm) terminal), you can instantly set up even in limited spaces such as the back of your LCD TV or the foot of a desktop PC. Connect the Bluetooth receiver via AUX for wireless connection
  • Precision Variable Low Pass Filter (20-160Hz) > Bass cut-off feature with spin knob allows you to freely set between 20Hz to 160Hz. Prevents overlapping of main speakers and subwoofers. > Acoustically Optimized: The filter tilt feature is 12dB/octave For example, set it to 80Hz for music playback to clear the outline of base gear and lower it to 40Hz for movie-watching and highlighting ultra-low frequencies like terrain. Designed with phase integration with the main speaker, providing seamless bass integration that cannot be seen in your ears
  • Equipped with NE5532 opire amplifier & high definition signal processing: Adopts the standard OP amplifier "NE5532" with over 40 years experience in the audio industry. > Noise Suppression Technology: High SNR (signal to noise ratio) 103dB reduces humm noise when silent. Optimized for input sensitivity of 0.775V and standard line output levels, it works stable from the headphone output of your smartphone to the professional audio interface. In particular, it reduces distortion in ultra-low frequencies below 80Hz, and faithfully reproduces the microscopic bass nuances of electronic instruments and movie soundtracks
  • All Weather Metal Housing & Installation Flexibility > 1.18mm thick metal housing shields electromagnetic interference (EMI) and provides rigidity to a lightweight 11.8 oz (325 g). > Durable design: The heat conduction design of the metal bottom plate prevents heat escaping within the rated power range. It supports a wide input voltage of DC12-24V, and can be used with car battery or portable power supply. It offers a space-saving bass enhancement solution for a variety of situations, including mounting bass shaker on a gaming chair, enhancing the sound of a flat panel TV or building a compact audio system for the study
