The amplifier uses forced-air cooling. The variable speed 
cooling fan draws air in from the front and exhausts it 
through the rear. The cooling fan operates at low speed when 
the heat sink temperature is below 65 °C (149 °F), or at high 
speed when the temperature exceeds 65 °C (140 °F). Please 
be sure that you do not block the air intakes or exhaust vents.
