Design concept:
The high output power and rich audio adjustment function of this power amplifier board can drive the speakers of various 2.1 audio systems and give full play to the sound quality of the speakers. Features a virtual surround function based on an analog circuit that creates a surround effect on two close left and right channel speakers. This amplifier`s sophisticated small size design and reasonable panel layout allow it to be embedded in a variety of audio system designs.
Function + Features
Straight-through pre-amplifier circuit, external analog audio input and Bluetooth can be used at the same time. The external analog signal directly enters the pre-amplifier without going through the Bluetooth chip, and the sound quality is preserved.
Design of Active Bass Filter with Adjustable Crossover Point and Gain
Left and right channels can adjust the mid-bass and treble
Simulate virtual surround function - when the potentiometer is adjusted in the middle position, the virtual surround is not used
Brand new original Texas Instruments TPA3118 chip, complete protection functions, including overload protection, over-voltage stop, output short circuit protection and overheat protection and output DC protection.
