2PCS Audio ZK-1001B 100W Bluetooth Power Amplifier Board Mono Amp

In this review of the 2PCS Audio ZK-1001B mono Bluetooth amplifier boards the bottom line is simple: these modules are for DIY audio builders who want a compact, modern 100W mono amp with flexible inputs and Bluetooth features. The reviewer found the boards to be well made and straightforward to integrate into small speaker builds or custom enclosures, with the biggest reason to buy being the combination of the TPA3116D2 power stage and Bluetooth 5.1 support that delivers clean, efficient output and low latency for streamed audio.

Key Features

• 100W Mono Output: Each board supplies up to 100W to a single speaker, making it suitable for medium-power driver configurations.
• TPA3116D2 Power Chip: The upgraded large chip provides efficient Class D amplification with lower heat and solid audio clarity for varied music sources.
• Bluetooth 5.1 with AAC: Modern Bluetooth 5.1 support including AAC decoding offers broader codec compatibility and reduced latency for connected devices.
• Multiple Inputs: Bluetooth, AUX, USB stick and USB sound card support let builders use local files or wired sources without extra converters.
• Customizable Prompts: The Bluetooth device name is changeable and the prompt tone volume can be adjusted, useful when deploying multiple units.
• Sound Presets: Ten natural sounds with up to 1023 combinations let installers tailor voice prompts or tones for product identification.

Who It's For

These boards are aimed at hobbyists, small-scale OEMs, and audio tinkerers building custom single-channel speaker projects, PA horns, or replacement amp modules. The wide supply range and support for 20-100W drivers make them handy for retrofitting older cabinets or creating compact powered speakers.

Customers who need a finished consumer amp with an enclosure, AC power supply, or stereo channels should look elsewhere; the package requires assembly of the shell and an appropriate DC supply between DC7-24V with adequate current, so some electronics experience is expected.

Pros & Cons

Pros

• High output capability with an efficient TPA3116D2 Class D amplifier that runs cooler than many linear designs.
• Bluetooth 5.1 plus AAC and low-latency operation improve wireless listening quality and compatibility.
• Multiple input options and adjustable prompt settings make the boards versatile for varied installations.
• Durable construction and upgrade chips give a reliable base for long-term projects.

Cons

• Sold as a 2PCS kit with the shell unassembled, so additional parts and a DC power supply are required before use.
• Mono output only; buyers needing stereo will need two channels and additional wiring and enclosures.
