Product Description
Feature:
● Original Imported TPA3251D2 Power Amplifier Chip
This amplifier adopts the original imported TPA3251D2 Class D power amplifier chip. As a high-performance Class D amplifier, it offers Class D efficiency while delivering genuine high-quality sound. The chip is equipped with an advanced integrated feedback design and proprietary high-speed gate driver error correction (Pure Path™ HD). This technology enables the device to maintain ultra-low distortion across the entire audio frequency range, while presenting clear sound quality.
● Bluetooth 5.1 Audio Power Amplifier Module
It features a Bluetooth 5.1 audio power amplifier module with 2.1 dual-channel stereo output. The output power is 220W×2 (left and right channels) + 350W (subwoofer), providing HiFi sound quality. The treble is clear and transparent, the midrange is soft and delicate, and the bass is powerful and impactful.
● Classic Design with Multi-Functional Main Knob
The amplifier has a classic appearance, and its main knob uses a rotary encoder that is commonly applied in high-end amplifiers, enabling 360-degree stepless adjustment. The knob has a smooth touch feel, and supports one-key start/stop (long press to start and stop), making operation simple and convenient.
● Mobile App Control Support
It supports control via a mobile app—the newly upgraded Sini Link app. The app allows users to modify the Bluetooth name, set a Bluetooth password, and turn the tone function on or off.
● Supported Audio Inputs
The supported audio input methods include Bluetooth 5.1, AUX, USB sound card, and USB flash drive (note: the USB flash drive must use the FAT32 file system, and the maximum supported capacity is 32GB).
● Heat Dissipation Mechanism
It adopts a heat dissipation mechanism combining a heat sink and a fan, ensuring safe use. A large-area aluminum alloy heat sink with a special-shaped structure and fan support are used to reduce the device temperature, effectively ensuring the product can operate at full power.
