Ventilation
Adequate ventilation extends the trouble-free life of
the MC3500. Always allow air to flow through the
ventilation holes on the bottom of the amplifier and a
means for the warm air to escape at the top. Refer to
figure 6.
Allow at least 19 inches (48.3cm) above the top; 6
inches (15.2cm) for the Front, Rear and Sides; allow
7/8 inch (2.2cm) below the Power Amplifier so airflow
is not obstructed.
