MBL N21 STEREO POWER AMP BLACK / CHROME

Electrifying Sound – The Power Supply

A commanding power supply is critical to an amplifier’s ability to produce sophisticated sound, and three factors are needed to ensure the smooth, distortion-free delivery of that power. It must be provided at steady and ample quantities over a broad range of speaker impedance loads, including at high volumes. It must be protected against interference from other electronic elements within the chassis. And its magnetic field can’t be allowed to affect other assemblies within. The N21 meets those criteria using a massive toroidal transformer with a large-sized sieve and charging electrolytic capacitors, ensuring the smooth supply of electricity. Two isolated copper foils in the transformer coils efficiently divert mains interference voltages as well as possible interferences within the amplifier. Finally, a shielding cup made of MU-metal encapsulates the transformer, keeping the electromagnetic fields in check and protecting the surrounding electronics.
