OUCUC ZK-1001B Bluetooth 5.1 Amplifier

The OUCUC ZK-1001B is a compact mono amplifier board rated for 100W output. It accepts a DC supply between 7 V and 24 V and connects wirelessly via Bluetooth 5.1 or through AUX and USB inputs. The built‑in volume control makes it straightforward for DIY speaker projects in a car or at home. The TPA3116D2 class‑D chip keeps distortion low while maintaining efficient power use across the supported 4‑8 ohm speaker range.

Capacity and headroom

The board delivers up to 100 W into a single channel, which suits small to medium DIY builds. Bluetooth range reaches 32 feet in open conditions, giving flexibility for phone or tablet streaming. Protection circuits guard against over‑voltage, under‑voltage, overheating and short circuits, so the module stays stable when pushed toward its limits. Performance tapers off if the load drops below 4 ohms or the supply voltage falls outside the 7‑24 V window.

Metal case and printed interface labels

A durable metal enclosure with top and bottom plates shields the internals from knocks and dust. The upgraded DC socket is designed for spark‑free connection, improving safety during repeated plug‑ins. Each input and control is clearly labelled on the protective board, reducing wiring errors during assembly. No extra software or remote is bundled; operation relies entirely on the onboard knob and the paired Bluetooth source.

Questions about this item

Will the ZK-1001B work with my existing 4-8 ohm speakers and a 24 V supply?

The amplifier supports 4-8 ohm speakers and a DC 7-24 V range, so a 24 V source falls within the specified input voltage.

How can I verify the TPA3116D2 amplifier is operating correctly after wiring it?

Pair a phone via Bluetooth 5.1 or connect a source through AUX or USB, then adjust the volume knob; clear audio output at up to 100 W mono confirms normal operation.

What comes in the box and what must I source separately for the ZK-1001B?

The board arrives with a protective metal case and printed interface labels; you must supply a DC 7-24 V power source, speakers rated 20-100 W, and any audio source device.
