Aiyima A70: 2.1 channel Class D amplifier with quality components

Aiyima A70 is a 2.1 channel Class D amplifier with quality components. It uses a TI TPA3255 amplifier IC combined with two NE5532 op-amps to deliver up to 2x 185W output power into 4 ohms. AIYIMA A70 has an original vertical form factor and a full set of connection interfaces located on the rear panel: balanced XLR/TRS 6.35 mm input, RCA input, active subwoofer output and speaker terminal output. The interface is complemented by a frequency cut-off potentiometer for the subwoofer output and a 12 V trigger input on a 3.5 mm jack. There is an impressive potentiometer on the front panel for precise volume control.

Thanks to the TI TPA3255 amplifier chip, the AIYIMA A70 amplifier is capable of delivering up to 2x 185 W into a 4 ohm load, which is significant power. The TI TPA3255 amplifier chip features integrated error-correcting feedback (PurePath™ UltraHD), resulting in very low distortion across the entire audio range and excellent overall sound quality.
