!0 Screw holes for security cover

If desired, you can use these two screw holes for attaching

screws to attach the cover.

!1 Air intakes

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.
