This series workunder high stability with great power supply in just 2-rack spaces. Air flow is from back to frontpanel to keep in a nice air circulation inside the Rack. The automatic fan, which affects machinestemperature includes various kinds of speed, therefore, this low-noise fan makes a good result incooling the heat from machines.MISTRAL amplifiers include 2 independent channels with separate protection system andpower supply. The independent protection system avoids opening circuit, short, wrong loading orover-heating. The special-designed protective system applies automatically restarting functionsupon 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 anyconditions.? 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.?
