Wuzhi Audio for Android

Quick summary

Wuzhi Audio is a companion app created by Qinghao Wuzhi Intelligent Technology Co., Ltd. for configuring and managing Wuzhi-brand Bluetooth amplifier modules (ZK series). It provides a centralized interface for changing hardware settings, tuning audio, and performing over-the-air firmware upgrades for compatible amplifier boards. The tool is aimed at hobbyists and audio enthusiasts who use external audio hardware and want deeper control than what physical knobs allow.

Supported amplifier models

• ZK-MT21
• ZK-HT21
• ZK-302T

Note: The application requires one of these compatible Wuzhi amplifier boards to operate — without a supported module the app cannot function.

Main capabilities

• Advanced equalization and presets: a 10-band graphic EQ with several factory presets (for example Classical, Rock, and Jazz) to help correct speaker or room tonal imbalances.
• Natural ambient modes: a library of ambient scenes (waves, rain, birds, etc.) with many mix combinations and a built-in sleep timer useful for automotive or overnight shutoff.
• Bluetooth controls: rename the Bluetooth broadcast name and set or change pairing passwords to limit unauthorized connections.
• Firmware management: perform OTA firmware updates for supported amplifier modules to keep device software current.
• Hardware tuning: access and modify internal parameters of the amplifier boards that are not adjustable via front-panel controls.
• Prompt and alert options: switch between spoken voice prompts and simple beeps, or disable prompts entirely for a quieter experience.

Known limitations and issues

• Language and translation problems: several interface elements suffer from poor localization, resulting in awkward labels and unformatted multi-language text blocks that can be confusing.
• Detection reliability: the app may occasionally fail to detect a connected amplifier even when the phone shows the device in system settings, forcing repeated connection attempts.
• Hardware dependency: none of the features are usable without a compatible Wuzhi board, so the app is essentially non-functional on its own.

Who benefits most

This utility is best suited for electronics hobbyists, DIY speaker builders, and home theater tinkerers who need granular control over Wuzhi amplifier modules. If you require robust tuning options and OTA update support and you have a supported board, the app is a powerful management suite — but expect occasional usability issues tied to detection and translation until those are resolved.
