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.

6. Test Procedure The semi-finished product test procedure 6.1Test Instruments 1. Power supply 2. Digital voltage meter 3. AP (Audio precision) 4. Oscilloscope 5. Two 8Ω(400W) resistors 6.2 Test procedures and specification a. Set LIMITER and BRIDGE switches at the position of OFF, turn the VRs of CH1 and CH2 to maximum, then turn on the power switch, the power LED will be illuminated (blue), OPERATING/PROTECTION LED is illuminated to be red at first, then become green after 2-5 seconds, the fan will be running.
