8.2 Cooling Fan Options
Every Macro-Tech amplifier has a built-in high-velocity
fan that provides optimum cooling. Two optional re-
placement fan blades are available for special cooling
requirements. Crown part C 6594-3 is a quieter, low-
velocity fan blade that in many cases can provide ad-
equate cooling. Crown part C 6593-5 is a reverse
air-flow fan blade which changes the direction of the air
flow in and out of the amplifier (not recommended for
the Macro-Tech 2400). Important: The optional replace-
ment fan blades should only be installed by a qualified
technician.

8.3 Level Control Shaft Lock
A security accessory, the shaft lock can be used to se-
cure your amplifier’s level controls in situations where
the front panel controls are subject to tampering. One
is needed for each channel. They can be ordered
through the Crown Service/Parts Department. For more
information, contact the Crown Service Department.
