Daakro ZK-1602T Bluetooth Amplifier Board 160W+160W Dual Channel – 12–24V, Bluetooth/AUX

Overview

Daakro ZK-1602T is a high‑fidelity Bluetooth amplifier board designed for DIY home audio projects. Built around the original TDA7498E HiFi chip with PurePath technology, it aims for ultra‑high resolution and low distortion, delivering a clean, immersive stereo image that supports two channels of forward‑facing sound.

Key benefits

• Dual TDA7498E HiFi chips with PurePath technology for detailed, accurate sound with low distortion
• 2.0‑channel configuration with 160W per channel, creating a robust stereo stage
• Dual input modes: Bluetooth 5.0 wireless and wired AUX for flexible source options
• Wide power flexibility from 12V to 24V, compatible with 12V, 19V, or 24V supplies
• Designed for 20–200W, 4–8Ω speakers, enabling compatibility with a range of enclosures
• Comprehensive protection including over‑voltage, under‑voltage, over‑temperature, short‑circuit, and reverse‑connection safeguards
• Guidance for optimal power matching to balance input levels, supply voltage, and speaker impedance

Power, compatibility, and setup

The board’s 12–24V input window makes it easy to pair with common power bricks or laptop/adapter supplies. Its 4–8Ω speaker compatibility and up to 200W total suggested range help you plan balanced, room‑filling sound without overloading components. When paired with proper wiring and enclosure design, the ZK‑1602T can support compact bookshelf rigs or larger desktop setups.

Inputs and connectivity

Two convenient input methods keep options open: Bluetooth 5.0 for wireless streaming and a wired AUX connection for direct devices like phones, laptops, or TVs. This flexibility supports quick, real‑world setups without additional adapters.

Protection and reliability

The built‑in protections guard against common issues, including over‑voltage, under‑voltage, over‑temperature, short‑circuit, and reverse connection. These safeguards help ensure stable playback during casual listening or project experiments.

Optimization tips

Real‑world performance depends on a harmonious match among the input signal, power supply quality, and speaker impedance. Higher impedance speakers may require more voltage or current to reach the same perceived loudness. Consider these factors when selecting drivers and enclosures for your setup.

What you can build

• DIY wireless bookshelf or compact floor‑standing speakers with a built‑in amp module
• Desk or media room systems that pair via Bluetooth or AUX for flexible playback
• Custom multi‑room audio projects using a shared 12–24V power supply
• Portable or fixed home audio rigs that balance power, clarity, and responsiveness
