DAMGOO ZK-1001U Mono Amplifier Board: 100W Hi-Fi Power with TWS, Bluetooth 5.3, and Multi-Input Versatility

For audio hobbyists, DIY speaker builders, and power users seeking a compact yet high-performance solution, the DAMGOO ZK-1001U Mono Amplifier Board delivers powerful sound in a portable, intelligent package. With its 100W output and True Wireless Stereo (TWS) capability, this amplifier board offers not just raw performance but the flexibility to support custom speaker builds, outdoor sound systems, and mobile audio applications.

At the heart of the ZK-1001U lies the TPA3116D2 professional Class-D amplifier chip, known for its efficiency and ultra-low distortion (less than 0.3%), producing crystal-clear mono audio that’s ideal for driving passive speakers rated between 20–100W with 3–8Ω impedance. Whether you're powering a single full-range driver or building a mono speaker enclosure for events or installations, this amp delivers clean, dynamic audio performance.

Engineered for mobile and outdoor use, the ZK-1001U includes a built-in boost circuit that intelligently transforms input voltages (from 9V, 12V, or 15V power sources) into a steady 19V or 24V output, with 24V as the default. This makes it perfect for use with battery-powered systems, such as portable speaker builds or vehicle-based audio setups. Just connect a compatible battery—like a 7.4V, 12V, or 21V pack—and enjoy high-efficiency amplification anywhere, without worrying about power fluctuation or drop-offs.

One standout feature is TWS pairing, allowing you to wirelessly link two mono boards together and create a full stereo sound system. With a simple triple-click of the multifunction knob, the devices synchronize effortlessly—one as the left channel, the other as the right—giving you an immersive and versatile stereo experience without needing a dedicated stereo board.

Connectivity is made seamless with Bluetooth 5.3, delivering faster, more stable connections with wider compatibility and longer range—up to 15 meters (49 feet). Whether you're connecting via Bluetooth, AUX, USB drive, or USB sound card, the ZK-1001U offers four input modes that support everything from smartphones and tablets to PCs and media players. It even includes AAC decoding for improved wireless audio quality over compatible Apple devices.

Control is simple and intuitive, thanks to the smart multi-function knob. Rotate to adjust volume, press to play/pause, double-click to skip tracks, triple-click to enter TWS mode, or long-press to power on/off. Plus, onboard bass and treble adjustment lets you fine-tune your sound profile to match your preferences or environment.

Compact yet loaded with features, the DAMGOO ZK-1001U is more than just an amplifier—it’s a versatile, high-efficiency audio powerhouse tailored for modern, mobile, and DIY sound systems. Whether used in cars, custom speakers, or outdoor audio setups, it brings pro-level performance in a plug-and-play format.
