This small, compact, versatile and high-performance O-Noorus PA-316 Class D amplifier incorporates two TI TPA3116D2 amplifier chips, each dedicated to one channel. It is thus capable of delivering a comfortable 2x60W at 4Ω (1% THD). In addition to a stereo RCA input and a USB-A port, it features a Bluetooth 5.0 receiver for wireless music streaming from a smartphone or tablet, for example. It is also equipped with a subwoofer output (RCA), offering the possibility of integrating a true 2.1 audio system. The front panel also features a volume knob associated with an NJW1194 chip, plus ±10dB bass and treble adjustment. All components are housed in a sturdy, sober CNC-machined aluminum case.
