This compact, versatile and high-performance O-Noorus OA70 Class D amplifier incorporates two Infineon MA12070 amplifier chips, each dedicated to one channel. It is thus capable of delivering a comfortable 2x65W at 4Ω. In addition to an single--ended stereo RCA input and a balanced 6.35mm TRS jack, it features a Bluetooth 5.0 receiver for wireless music streaming from a smartphone or tablet, for example. The high-resolution Bluetooth transmission codecs aptX HD and LDAC are also supported. All components are housed in a sturdy, sober CNC-machined aluminum case.
