1. Introduction

ALTO MISTRAL amplifiers are series of innovative design power amplifiers. This series work under high

stability with great power supply in just 2-rack spaces. Airflow is from back to front panel to keep in a nice air

circulation inside the Rack. The automatic fan, which affects the temperature of machine includes various

kinds of speed, therefore, this low-noise fan makes a good result in cooling the heat from machines. MISTRAL

amplifiers include 2 independent channels with separate protection system and power supply. The

independent protection system avoids opening circuit, short, and wrong loading or over-heating. The special-

designed protective system applies automatically restarting functions upon the default status and then goes

back to normal.All electronic inputs equip standard power connectors.And all inputs are electronic balanced,

with hi-quality transformer, MISTRAL amplifiers provide an outstanding performance in any conditions.

.Innovative design and high stability power amplifiers.

.Fan-cooledAB class high power amplifier in 19”rack, 2Usize

.Rugged amplifiers in a strong, compact chassis.

.2 independent channels with separate protection system and power supply

.Smart-designed protection system for auto re-operation after fault.

.Auto-adjusting speed fan.

.4LEDs for operation/protection, limit, power on and clip

.High-current toroidal transformer designed for high power at 2Ohms with low noise.

.Independent DC and thermal overload protection on each channel.

.IEC standard power connectors.

.Binding post and NEUTRIK® SPEAKON outputs power connectors.

.Balanced XLR inputs/ parallel outputs.
