About the N21
The MBL Akustikgeräte N21 is a German-made Noble Line stereo power amplifier introduced around 2017. It uses MBL’s LASA 2.0 amplifier technology, a symmetrical internal layout, a heavily shielded analog toroidal-transformer power supply, high-current output capability, and soft clipping. The amplifier is designed to maintain stable tonal balance with difficult or impedance-varying loudspeaker loads and can deliver 380 watts per channel into 4 ohms. It accepts one balanced XLR input and one floating-balanced RCA input, includes MBL SmartLink networking, and provides an SD-card slot for firmware or display updates. MBL’s official product information and current dealer listings indicate that the N21 remains an actively listed product; Some third-party references differ slightly on weight and external depth, so the manufacturer’s published figures are preferred.
