ARRAROWN ZK-502T Power Amp – Bluetooth 5.0 2x50W Mini Stereo Amplifier Module

Elevate your DIY home audio with the ARRAROWN ZK-502T

The ZK-502T is a compact 2.0 channel power amplifier module designed for DIY speakers and small to mid sized setups. With Bluetooth 5.0 and an AUX input, it provides easy wireless or wired source options and delivers a clear, engaging stereo signal with only light distortion at higher levels.

Directly shaping the sound is simple thanks to independent treble and bass controls. This allows you to tailor the tonal balance to your room or listening preferences without needing an external processor. The module also features advanced design choices such as AM interference suppression and a shielded power inductance, which help keep the front-end noisy-free and the midrange clean for a more natural overall balance.

• Bluetooth 5.0 plus AUX input, 2.0 channel stereo output for versatile source options
• Independent treble and bass adjustments to tune your sound profile
• AM interference suppression and shielded power components for lower noise
• Over voltage, under voltage, over-heat and short-circuit protections for safer use
• Printed interface labels on the protective plate simplify installation and wiring

Reliability and safety you can rely on

Built with protective features that guard against common power issues, the ZK-502T helps prevent unexpected shutdowns during casual listening or small gatherings. A sturdy protective plate keeps connections organized and reduces the chance of miswiring, especially in DIY projects or compact enclosures.

Power, footprint, and installation

The module measures a compact 4.72 by 3.94 by 0.7 inches, making it suitable for tight enclosures, portable builds, or rack shelves. It runs on DC 12 to 24 volts and requires a solid supply (higher voltage and current yield stronger performance). With two passive speakers rated up to 50 W each, you can pair this board with a simple sourcing setup to achieve a fuller, more impactful stereo image.

Setup is approachable even for beginners. The protective plate includes illustrated interface references, so you can connect inputs, outputs, and power without hunting for a manual. When paired with compatible speakers and a suitable power supply, the ZK-502T can support engaging home audio experiences across a range of spaces.
