Product description

100W Mono Amplifier Board

The ZK-1001U is a 100W mono Bluetooth amplifier board based on the TPA3116D2 chip, specially designed for portable audio systems and DIY speaker projects. This amplifier board supports TWS (True Wireless Stereo) functionality, allowing wireless stereo pairing between two modules. Additionally, the ZK-1001U features treble and bass adjustment, enabling users to fine-tune the sound according to their preferences for a more dynamic and immersive listening experience.

TWS Function - Achieving True Wireless Connection

1.Turn on two power amplifiers of the same model.

2.Choose either amplifier, then press the master volume knob (with button function) inward three times. The blue TWS indicator will start flashing, and the other amplifier will automatically pair with it to form a stereo setup.(If pairing is not successful within 15 seconds, pairing mode will exit automatically. You can try again by pressing the knob three times.)

3.Once paired, the selected amplifier will function as the left channel, with its blue indicator staying solid. The other amplifier becomes the right channel, and its blue indicator will flash slowly.

4.The next time the units are powered on, they will automatically reconnect. To cancel the pairing, simply press the knob on either amplifier three times.

Equipped with a heatsink: Effectively lowers the working temperature of the amplifier chip, ensuring stable operation of the amplifier board.

TPA3116D2 Chip: Uses the TPA3116D2 digital amplifier chip, with low distortion and pure, powerful sound quality.

Boost circuit: Can be boosted to 19V or 24V, meeting the power requirements of different speakers.

Bluetooth/3.5mm AUX/USB Sound Card/USB Flash Drive Input

The ZK-1001U amplifier board features three audio input modes: Bluetooth 5.3, 3.5mm AUX, and USB, offering strong compatibility with various audio sources. With flexible input switching, it allows you to enjoy music effortlessly in different scenarios.
