Wuzhi Audio ZK-1001U 100W Mono Amplifier Board

The Wuzhi Audio ZK-1001U is a compact mono amplifier board that delivers up to 100W output with TWS wireless pairing and Bluetooth/USB/AUX inputs for DIY and vehicle audio systems.

Engineered around a genuine TPA3116 chip, the ZK-1001U combines high-output power, wide voltage compatibility, and simple controls to upgrade small speakers, custom enclosures, or mobile audio rigs. Its built-in boost circuit stabilizes lower input voltages to the board’s required operating level while three rotary knobs let you shape volume, bass and treble. Add True Wireless Stereo (TWS) to link two boards for left/right channels without extra wiring.

How does this amp handle different power sources in vehicles and battery systems?

The ZK-1001U accepts a broad 9–24V input range and includes an auto-boost circuit that raises lower voltages to the board’s working level. This makes it compatible with common vehicle batteries and smaller DC power supplies while preserving reliable output.

• Wide input range: 9–24V DC accepted for flexible installation.
• Auto-boost: boosts 9V or 15V inputs to stable 19V or 24V (default 24V) as needed.
• Suitable for cars, motorcycles, RVs, and portable battery packs.

What connectivity options are available for playback and control?

Playback options include Bluetooth 5.0 for wireless streaming, USB for direct digital playback, and a 3.5mm AUX input for wired sources. The multifunction rotary knob doubles as a controller for play/pause, track skipping, TWS pairing and power, minimizing extra buttons.

• Bluetooth 5.0: low-latency wireless audio from phones or streamers.
• USB input: plug-and-play media playback from USB drives.
• AUX input: universal wired connection for older devices.
• Multifunction button: single/double/triple/long-press actions for common controls.

How do I get stereo sound with mono amplifier boards?

Use the board’s True Wireless Stereo (TWS) feature to pair two ZK-1001U units; one becomes the left channel and the other the right. Pairing is quick — a short press of the multifunction knob syncs the two boards wirelessly and creates a stereo stage without speaker crossover wiring.

• Quick TWS sync via multifunction knob press.
• Creates left/right stereo from two mono boards for full imaging.
• Ideal for DIY enclosures or when running separate amp modules to each speaker.

What tone controls and adjustments are available on the board?

The ZK-1001U provides three physical knobs for master volume, bass, and treble so you can tailor sound without external DSP. These analog controls are immediate and useful when tuning system response for different speaker sizes or listening environments.

• Master volume knob for overall level control and power/transport functions.
• Bass and treble knobs for simple tonal shaping on the fly.
• No separate software required — direct hardware adjustment.

Who is this for: The Wuzhi Audio ZK-1001U is aimed at DIY audio builders, small- to medium-sized vehicle audio upgrades, and hobbyists who need a high-power mono amplifier with flexible inputs and simple hardware controls. Choose this board if you want a compact, TPA3116-based amplifier that supports wireless stereo pairing, works across a wide DC voltage range, and gives hands-on tone control without complex setup.
