Micro-Tech Series Power Amplifiers

5 Advanced Features

and Options

5.2 Accessories

5.2.1 Cooling Fan Options

Every Micro-Tech amplifier has a built-in high- velocity fan that provides optimum cooling. Two optional replacement fan blades are avail- able for special cooling requirments. 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 rec- ommended for the Micro-Tech 2400).

Important: The optional replacement fan blades should only be installed by a qualified technician.

5.2.2 Input Connectors Option

The MT-BB is an accessory panel that provides barrier-block input connectors. An MT-BB accessory might be desirable in applications requiring bare wire connections. It can also be used to daisy-chain an input signal from one amplifier to another, just like the MT-XLR.

The MT-BB must be installed at an authorized service center or the Crown factory.

5.3 Filter Cleaning

A dust filter is provided on the air intake to the cooling system (Figure 4.1, letter “B”). If this filter becomes clogged, the unit will not cool as efficiently as it should and may produce lower- than-normal output levels due to high heat-sink temperature.

To remove the filter, use a phillips screwdriver to remove the three screws that hold the front

grille in place. Wash the filter with mild dish- washing detergent and warm water. Be sure to

dry the filter before installing it. ReplacementFigure 5.1 MT-BB Input Panel Accessory filters may be ordered from the factory.

Dust filters are not 100% efficient. So, depend- ing on the local environment, the internal heat sinks of the amplifier will benefit from periodic cleaning by a qualified technician. Internal cleaning information is available from our Technical Support Group.
