Bluetooth 4.0 Receiver Digital 2.1 Class D HIFI Power Amplifier Board Bass Audio Module

Description:
The amplifier board uses high grade original chip components including TPA3116D2 chip instead of disassembled parts. With carefully selected components, the quality is quite good, including blue audio correction capacitors, small sealed potentiometer for volume adjustment, two high temperature low resistance 4700UF power supply filter electrolysis capacitors, high-frequency extension, high efficiency audio output inductors and 1.6mm fiberglass board.

Features:
This power amplifier board supports power delay output protection, no impact on the sound, protecting expensive speaker.
This board provides high output power with low distortion, high sound reproduction, no noise or interference current sound.
Dual power supply mode supports DC 24V single power supply, or 18V AC power supply with rectification filter circuit.
It supports various audio input methods to meet the different modules including Bluetooth receiver, or 3P audio input jack.
Supports bass cutoff frequency adjustment, cutoff range from 180Hz to 250Hz.
Designed with a reverse connecting protection circuit to avoid improper use or damage from a inversion polarity connection of power supply.
These high quality gold color slotted heat sinks ensures a good heat dissipation.
