MA 2402 Power Amplifier

5 Advanced Features and Options

For PIP2s featuring ribbon cable connectors, simply locate the two connectors on the under- side of the PIP circuit board, then connect the two input ribbon cables coming from the ampli- fier (see Figure 5.3). Both ribbon cables should run smoothly from the amplifier to the PIP card. Insert the PIP and attached cables into the PIP opening in the back of the amplifier, then screw securely into place.

WARNING: Disconnect power to the amplifier when installing or removing a PIP module.

5.3.2 Cooling Fan Options

Every Macro-Tech amplifier has a built-in high- velocity fan that provides optimum cooling. Two optional replacement 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 adequate 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 2402). Important: The optional replacement fan blades should only be installed by a qualified tech- nician.

5.3.3 Level Control Shaft Lock

A security accessory, the shaft lock can be used to secure your amplifier's level controls in situations where the front panel controls are subject to tamper- ing. One is needed for each channel. They can be ordered through the Crown Service/Parts Depart- ment, part number D 6932-4. For more information, contact your local Crown dealer or Crown Technical Support.
