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 specialdesigned 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-cooled AB 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.
