INTRODUCTION

Thank you for choosing Stello M200 monoblock power amplifier from April Music.

The Stello M200 is a monoblock power amplifier with 140W output.

Not only does it have outstanding musical performance, but it also has a capacity enough to drive most

of the high-end speakers in the market.

The M200 has six power transistors. To ensure top musical performance and long operating life, special

circuits are applied which are unique to the M200. Remote power switching is available by a 12V

Trigger signal through connection with a preamplifier or a surround processor.
