High-Power 2-Channel Bluetooth Amplifier Module with Bass and Treble Control for Speakers

Discover our high-performance Bluetooth amplifier module, model ZK-502T, designed to transform your audio system. This dual-channel stereo amplifier module is built around the powerful TPA3116D2 integrated circuit, ensuring clear sound and AM interference suppression.

**Power Supply and Power:**

For optimal performance, we recommend an 18V, 19V, or 24V power supply with a current of 5A or more. A 9V/12V or 1A/2A power supply can also be used, but the output power will be reduced. Note that at maximum volume with a low power supply, distortion may occur. Output power varies with voltage: enjoy 30W x 2 at 24V with a 4Ω speaker, or 20W x 2 at 19V with an 8Ω speaker.

A 12V/1A power supply is perfectly suited for 3- to 4-inch speakers, while a 19V/5A or higher will easily drive 8- to 10-inch speakers. **Connections and Operation:** This module offers two audio input modes: Bluetooth 5.0 and linear AUX input. The Bluetooth connection takes priority and offers a stable range of up to 10 meters without obstructions. It supports automatic reconnection. To use the AUX mode, simply plug in the cable; ensure the Bluetooth connection is disconnected. The module intelligently switches between sources. **Sound Control:** Customize your listening experience with the two included potentiometers. The TREBLE (high frequency) potentiometer, located on the left side, allows you to boost or attenuate the high frequencies. The BASS potentiometer in the center controls the low frequencies. Turn it right to boost, left to attenuate. The center position provides a neutral, unaltered sound. **Safety and Compatibility:** Equipped with multiple protections (over/undervoltage, overheating, DC current detection, short circuit), this module ensures safe and long-lasting use. It is compatible with speakers from 4 to 8 ohms and with a power output of 15 to 100W. **Your Order Includes:** 1 x ZK-502T Bluetooth Amplifier Module 2 x Protective Covers 1 x Heat Sink Block 4 x Spacers 4 x Mounting Brackets 9 x Screws 1 x DC Power Cable 1 x Screwdriver Enjoy easy installation and an enhanced audio experience for your DIY projects!
