8 Accessories

8.1 Cooling Fan Options

Every Micro-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 Micro-Tech 2400 ). Important: The optional replace-
ment fan blades should only be installed by a qualified
technician.

8.2 Input Connectors

There are two input connector accessories available at
the time of this printing: the MT-XLR and the MT-BB .
Important: The MT-XLR and MT-BB must be installed at
an authorized service center or the Crown factory.

8.2.1 MT-XLR

The MT-XLR is an accessory panel that provides two
standard 3-pin female XLR input connectors. The
MT-XLR accessory makes it easy to quickly change
connections in a system that uses standard XLR con-
nectors. It can also be used in systems that need to
daisy chain an input signal from one amplifier to an-
other. Because the MT-XLR connectors are in parallel
with the amplifier's built in phone connectors, an input
signal fed to either input can be fed to another ampli-
fier from the unused connector for that channel.

8.2.2 MT-BB

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