AIYIMA A08 PRO TPA3255 Power Amplifier
Bluetooth 5.0 UV Meter, 300W+300W
HiFi Class D Stereo Digital Audio Amplifier
2.0/2.1 Channel Amplifier for Passive Speakers

1. [Unique and Wonderful Combination]
We have integrated the A08 PRO amplifier with a VU meter into such a mini size.

2. [Bluetooth 5.1 Wireless HD Audio Transmission] Multiple audio input methods, including Bluetooth and RCA, can meet more of your needs.

3. [HiFi Clear Sound with Tone Control]
High-quality internal components such as resonance circuits, concise wiring, and phase-mode inductors deliver a warm and sweet sound without noise. The sound is typical of Class D's brightness, with good bass response and bright (yet dynamic) midrange and treble.

4. [Simple, Compact, yet Powerful Design]
Adopting the TPA3255 chip, each channel can output 300W (into a 4Ω load), easily driving 3-8Ω passive speakers. It also includes a low-frequency output for easy connection, allowing you to build powered speakers and a 2.1 channel system, significantly enhancing the bass effect.
