About the N51
The MBL N51 is a high-end stereo integrated amplifier from MBL’s Noble Line, using MBL’s LASA 2.0 switching-amplifier technology. It delivers 2 × 210 W into 8 ohms, 2 × 380 W into 4 ohms, and 2 × 620 W into 2 ohms. The analog design provides RCA and balanced XLR line inputs, a pass-through input for use with an external surround processor, RCA preamplifier and record outputs, Unity Gain functionality, and an optional phono module. MBL SmartLink connections support communication with compatible MBL components, while the SD-card slot is used for software updates rather than music playback or network streaming. The N51 has subsequently been superseded in MBL’s lineup by the N51 MKII.
