1

High-end components: The A20 amplifier uses the TPA3255 Class D amplifier chip and is equipped with German WIMA, Japanese Genicon, Ruby capacitors and gold-plated terminals. achieving a signal-to-noise ratio (SNR) of up to 116dB and a distortion rate as low as 0.002%

2

HPF High Pass Filter Adjustment: The TPA3255 desktop amplifier features an adjustable high pass filter (HPF) with an adjustable range of 60-200Hz. It optimises mid and high frequencies for clear and transparent mid and high tones while minimising low frequency interference.

3

Rich connectivity options: with RCA/XLR input interfaces and a12V trigger

4

Balanced inputs effectively reduce noise, providing pure stereo output, and restore true sound quality through independent low-frequency drivers

5

The 12V trigger input interface enables synchronised control with other devices, simplifying the power switch operation process without the need for separate operations

6

Enhanced sound quality: The A20 Class D amplifier uses two LME49720 (plug-in) and seven NE5532 (surface-mount) operational amplifier chips to achieve ultra-low distortion, low noise, and extremely transparent sound quality without colouration

7

BYPASS Function: The A20 Integrated Amplifier features a bypass mode, which reduces audio quality loss, making it a high-fidelity pure power amplifier

8

PFFB circuit design: A20 uses PFFB (post-filter feedback) technology to effectively overcome the common load dependence problem of Class D amplifiers, improve distortion, enhance frequency response, and thus greatly improve sound quality and performance.
