Micro-Tech 600/1200/2400 Power Amplifiers
Reference Manual
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 re-
placement 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
. Im-
portant: 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 another.
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 amplifier 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
.
