S220HS 2.1 Channel Bluetooth Power Amplifier Board - 160W+160W+220W

In this review of the S220HS 2.1 Channel Bluetooth power amplifier board the bottom line is simple: build a compact, powerful audio front end with flexible inputs and app control. The board uses dual TDA7498E chips and accepts DC 12-36V, delivering substantial peak power that suits DIY home audio, portable speaker projects, or car installs. The most convincing reason to buy is the combination of high output potential and modern conveniences like Bluetooth name/password setting and an adjustable EQ via a dedicated app.

Key Features

• TDA7498E dual chip: Provides the raw power for the 2.1 configuration so the board can drive large speakers with high peak output.
• Wide voltage range: Runs from DC 12-36V so it is compatible with typical car systems and many bench power supplies.
• Three input modes: Offers Bluetooth, AUX 3.5mm and USB (sound card and flash drive) so users can connect phones, TVs, and USB media easily.
• App control and custom Bluetooth ID: Lets users set the Bluetooth name and password, switch input sources, and adjust sound with the mobile app for a more controllable setup.
• Treble and bass knobs: Physical tone controls provide instant, tactile EQ adjustment without opening the app for quick sound shaping.
• USB flash drive support: Plays FAT32 formatted USB drives up to 32GB, useful when a network source is unavailable.

Who It's For

The S220HS is best for hobbyists and small-scale integrators who want a powerful, configurable amplifier board for custom speakers, desktop systems, or vehicles. Its dual TDA7498E design and multi-input flexibility make it a good fit when driving separate left/right plus subwoofer channels is required.

It is less suited to users who need a finished consumer product with casing, remote control, or regulatory certificates out of the box; those buyers should look for prebuilt receivers or enclosed amplifiers. Also, installers who cannot provide a 12-36V supply will need an external power solution.

Pros & Cons

Pros

• High peak power output thanks to two TDA7498E chips, giving strong performance for 2.1 speaker setups.
• Multiple input options including Bluetooth, AUX and USB make source selection flexible for many uses.
• App with Bluetooth name/password settings and tone controls adds modern convenience and personalization.
• Physical treble and bass knobs allow fast, hands-on EQ adjustments during use.

Cons

• Sold as a board only, so buyers need to provide power, enclosure, and possibly additional wiring for a finished install.
• Peak power figures are high but actual continuous output will depend on supply voltage and speaker load, so expectations should be realistic.
