1. INTRODUCTION
The MC250.8 eight Channels Power Amplifier is designed for professional use and provides unparalleled quality. It
Includes soft start, signal limit, four variable-speed-low-noise fans, and includes eight independent channels with separate
power supply. Each channel is equipped with independent protective circuitry against open circuit, short circuit,
mismatched loads and overheat. Furthermore, every channel has also a protection LED that lights up before the
amplifier is in normal operation and flashes when the amplifier is in over-load protection or short-circuit protection, and
lights up when over-heat protection or DC protection occurs. CLIP LED that shows true amplifier clipping. The high
qualitycomponents and the carefully designed circuits ensure excellent audio performance and an extremely linear
frequency response, giving crystal-clear sound in the high range and an up-front, full-bodied bottom end. This amplifier
guarantees total reliability and a trouble-free use even in the most demanding conditions. We believe the MC250.8
not only look great, but provide a perfect performance, what you get is unprecedented performance at an incredibly
attractive price.
