Features:

All-in-One DAC Amplifier:
Using the ES9038Q2M high-performance decoder chip, combined with the TPA3255 high-power ultra-low distortion amplifier chipset, the AIYIMA A80 supports DSD512 and PCM ultra-high-resolution audio, providing users with rich and delicate sound details.

Hi-Res Audio Amplifier:
The AIYIMA A80 Bluetooth Power Amplifier adopts the high-performance TPA3255 Class D amplifier chip, with Rubycon capacitors, German WIMA capacitors, and professional audiophile-grade components. It ensures high power output, achieving a total harmonic distortion (THD) as low as 0.006% and a signal-to-noise ratio (SINAD) of 109dB, delivering exceptional Hi-Fi audio sound.

Multiple Inputs:
The A80 provides a variety of input interfaces, including Bluetooth, USB, optical, coaxial, and TRS, covering almost all modern audio source requirements. It seamlessly connects with TVs, Bluetooth devices, and high-quality sound systems to meet the needs of different scenes and audio devices.

Versatile & Flexible:
Supporting 12V Trigger input, the amplifier is compatible with various control systems or automation equipment, allowing it to link with other home audio components. This simplifies the operation process and enhances the flexibility of your system.

Wide Range of Uses:
The A80 supports 3.5mm AUX and RCA outputs, suitable for connecting different types of amplifiers or audio equipment. The 3.5mm output connector can be flexibly set up for 2.0/2.1-channel home audio receiver systems.

A80 Standby Function:
The amplifier will enter Standby mode after 5 minutes without signal input, saving energy and extending the lifespan of the power amplifier.

PFFB (Power Feedback) Function:
The AIYIMA A80 is equipped with PFFB technology, which provides real-time feedback to enhance the amplifier’s performance, improving power efficiency and further reducing distortion. This function contributes to superior sound quality by maintaining stable operation even under demanding conditions.
