320W Power Amplifier Board 160W2 Stereo - Treble & Bass Control

In this review of the 320W Power Amplifier Board (ZK-1602T) the bottom line is simple: it is for DIY audio builders and small home theater setups that need a compact, high-power stereo amp with tonal control. The board uses a TDA7498E HIFI chip and promises up to 160W per channel across a wide DC input range, so the most compelling reason to buy is its combination of strong output power and onboard treble and bass adjustment in a single, easy-to-integrate module.

Key Features

• TDA7498E HIFI chip: Delivers high-fidelity stereo dual-channel output capable of sustained high-power operation for clean, loud playback.
• Wide voltage input: Accepts DC 15-36V so it can run from a variety of standard 5.5mm x 2.1mm adapters and common power supplies.
• High output power: Rated up to 160W per channel, giving enough headroom for medium to large passive speakers in a home setup.
• Treble and bass control: Adjustable high and low frequency knobs allow you to tailor tonal balance and increase perceived bass impact without external EQ.
• Protection functions: Built-in short-circuit, over-current, over-temperature and reverse polarity protections help prevent damage during use or installation.
• Compact compatibility: Standard DC plug compatibility and simple connections make it straightforward to fit into amps, small enclosures or hobby projects.

Who It's For

The board is best suited for hobbyists, small home theater builders, and installers who need a powerful, self-contained amplifier module with tonal controls and protection circuits. It works well where a compact, high-power amp is required and where users can provide an appropriate 15-36V DC supply and passive speaker load.

It is less appropriate for someone wanting a finished, plug-and-play consumer receiver with built-in networking, multiroom features, or a fully enclosed chassis. Also, buyers who cannot troubleshoot occasional wiring or power issues may prefer a factory-built powered speaker or integrated amp with a full warranty and service.

Pros & Cons

Pros

• Strong power delivery up to 160W per channel for loud, dynamic playback.
• Onboard treble and bass controls provide convenient tone shaping without extra gear.
• Multiple protection mechanisms reduce risk of damage during faults or miswiring.
• Simple compatibility with widely available DC adapters and easy assembly appreciated by customers.

Cons

• Some users report occasional power-on or connectivity issues, so basic troubleshooting may be required.
• As a bare board, it lacks an enclosure and some consumer-facing conveniences like front panel indicators or remote control.

Our Verdict

The 320W Power Amplifier Board is a strong value for DIYers and small home theater builders who want high output and built-in tone control in a compact package. With the TDA7498E chip and multiple protections it delivers performance close to much larger amps, but prospective buyers should expect to mount it in an enclosure and provide a suitable DC supply.

Frequently Asked Questions

What power supply is required?
The board accepts DC 15-36V and is compatible with common 5.5mm x 2.1mm adapters; choose a supply that can deliver sufficient current for your speaker load.

Does it include Bluetooth?
The source description references a BT variant; this board emphasizes the TDA7498E stereo amp and tonal controls-confirm your specific module includes Bluetooth if that feature is required.

Is it safe to run without additional protection?
The module has built-in short-circuit, over-current, over-heat and reverse protection, but installing it in a ventilated enclosure and using a properly rated power supply is recommended.
