Wuzhi Audio ZK-1602T 320W 2.0 Channel Amplifier

The Wuzhi Audio ZK-1602T is a compact 2.0-channel amplifier board delivering up to 160W per channel with adjustable bass and treble and broad protection features.

Compact and engineered around the TDA7498E high-fidelity amplifier chip, this 15–36V power module brings high-power stereo output to DIY audio builds, desktop speaker systems, and compact AV rigs. It pairs high continuous output with user controls for tone shaping and on-board safeguards to protect the circuit and connected speakers. The board ships in black and accepts common DC barrel adapters, making it easy to integrate into existing setups.

How much power can this amplifier board actually deliver?

The ZK-1602T uses the TDA7498E chip to provide up to 160W per channel into suitable speaker loads, totaling 320W peak stereo output under optimal conditions. Real-world power depends on supply voltage, speaker impedance, and thermal management.

• Peak output: 160W × 2 channels (chip-rated)
• Recommended supply: 15–36V DC for reliable performance
• Power dependent on speaker impedance and heat dissipation

What tone controls and audio adjustments are available?

This board adds separate treble and bass knobs so you can shape the high and low frequencies independently of the master volume. Adjusting tone lets you emphasize punchy low end or clearer highs to match room acoustics and speaker characteristics.

• Independent treble control for high-frequency clarity
• Independent bass control for deeper low-end impact
• Master volume to set overall output level

Which power supplies and speaker setups are compatible?

ZK-1602T accepts DC inputs between 15V and 36V and works with commonly available 5.5mm × 2.1mm barrel adapters. It’s compatible with a wide range of passive speakers; choose speaker impedance and an appropriate adapter to match your use case.

• Input range: 15–36V DC via standard 5.5×2.1mm plug
• Use speakers rated for high-power handling for best results
• Ensure proper heatsinking or ventilation at high output

What protections are built in to keep the board and speakers safe?

The module includes multiple protection mechanisms that monitor and respond to common faults to prevent damage. When limits are exceeded the board reports faults and reduces risk to the amplifier and connected load.

• Short-circuit protection to guard output stages
• Over-current and over-temperature monitoring
• Anti-reverse polarity input protection to prevent damage

Who is this for? The Wuzhi Audio ZK-1602T is aimed at electronics hobbyists, DIY speaker builders, and small-scale audio installers who need a powerful, tone-adjustable stereo amplifier in a compact board form. It’s well-suited for desktop stereo systems, compact powered bookshelf speakers, and experimental audio projects where adjustable treble/bass and reliable protection are priorities. Avoid pairing it with underspecified power supplies or speakers with low power ratings without adequate cooling and proper impedance matching.
