Compact yet powerful 100W bass output: This unit employs TI's standard Class D amplifier chip, the "TPA3116." With a rated output of 100W (at a 4Ω load), it can easily drive passive subwoofers and bass shakers. Despite its small size, it faithfully reproduces the low-frequency energy of explosions in movies and shockwaves in games. It is ideal for adding bass that is often lacking in desktop audio and home theater systems. Wide compatibility with two input systems: RCA and AUX. The input terminals are equipped with two systems: a standard stereo RCA and a 3.5mm AUX that can be directly connected to smartphones and tablets. It can connect to most audio equipment, including TVs, PCs, CD players, streaming devices, and even smartphones and game consoles. It can be easily integrated into existing audio systems and adds a dedicated bass channel. *Caution: Do not connect to both RCA and AUX simultaneously. This may cause signal interference or jamming. Simple control with a single knob: Power ON/OFF and output level adjustment are integrated into one knob. Turn it to adjust the volume, press it in to turn the power on or off. You can instantly adjust only the subwoofer output without changing the settings of the main system. You can easily control the strength of the bass at your fingertips, whether you are watching a movie or playing a game. Clear, low-distortion bass delivered by the NE5532 op-amp: The amplification stage employs the NE5532 op-amp, a well-established audio component. This op-amp is known for its excellent low-distortion and low-noise characteristics, and is particularly renowned for its high-fidelity low-frequency reproduction. The bass output from the subwoofer is not simply "loud," but also reproduces texture, tightness, and subtle nuances with clarity. You can enjoy the basslines of music and sound effects in movies without any distortion. Robust aluminum casing and space-saving design: The casing is made of aluminum, which offers excellent heat dissipation and rigidity. The slim body, measuring 30mm in height and 90mm in width, fits neatly into narrow spaces such as on a desk, in the gap of a rack, or next to a TV stand. Its robust construction ensures stable operation even during prolonged use. It solves the "lack of bass" problem for gamers, audiophiles, and home cinema enthusiasts without taking up much space. Compact, durable, and designed for bass enthusiasts: The NS-21G features a robust, all-metal case built for long-term use, yet its compact size allows it to fit anywhere on your desk or shelf. It's perfect for gamers, audiophiles, and home theater enthusiasts who want more powerful bass without sacrificing space. The NS-21G is a compact mono amplifier designed specifically for passive subwoofers and bass shakers, delivering powerful bass to movies, games, and music. Equipped with a highly efficient TPA3116 Class D amplifier chip and the low-distortion NE5532 operational amplifier, it achieves clear and powerful bass reproduction. With two inputs—RCA and 3.5mm AUX—it easily connects to a wide range of devices, including TVs, smartphones, PCs, and game consoles. Its compact aluminum casing fits easily into desk or rack spaces, making it a reliable partner for bass enhancement in everything from living room home theaters to gaming desks.
