AOAOHT DA2 HiFi Pure Digital Input Class-D Amplifier TAS5624x2 200W Digital Signal Modulation PWM Signal

Introduction:
- The design goal of DA2 is exquisite and noble, manifested in a clean sound floor and ultimate mid to high frequency performance. However, it is not intentionally achieved by raising certain frequency bands. Instead, DSP technology is used to align the phase to almost zero error. The precise phase brings unparalleled structural performance, which in turn makes the sound's lines, delicacy, transparency, and weak signals all enter the ear. Because all sound signals are real and exist, although it has extremely excellent mid to high frequency performance, there is no such thing as the harmonic signal that other devices intentionally pull high frequency to bring, so there is no auditory fatigue at all. The sound is like crystal clear and slightly sweet mountain spring water.
- Reminder: If the sound doesn't sound like the above description, but rather fat low frequency, and muffled medium frequency, it is likely that the LC parameters of DA2 do not match the speaker (the matching problem between amplifier and speaker is an old problem). Do not worry, adjust the EQ function of DA2 appropriately to reduce the frequency by about 2dB around 40-150Hz (according to your own listening experience).
- Recommend digital signal connection instead of RCA.
