SM SERIES High Dynamic Professional Power Amplifiers

SWITCH-MODE POWER SUPPLY AMPLIFIERS

The SM amplifier range offers the high dynamic power of Master Audio amplifiers in a lightweight format.

Their proven technology combines a switch-mode power supply with Class H amplification modules, allowing a considerable weight reduction without losing sound quality and reliability.
They incorporate the soft-start circuit with gradual volume increase, clip limiters and special protection features such as temperature control, overcurrent, DC and output short-circuit.
