Due to the weight of the unit, it should be securely fastened at the front and the back of
the cabinet. If the racks are carriage ones, it is advisable that have trays in order to allow the
power amplifier to rest on its base and in an elastic cradle, if possible. It is advisable, leave a
separation space between amplifiers and other units in order to facilitate its cooling, upon
mounting the amplifier in a rack.
In the mounting, either fixed or in rack, the cooling vents placed in the front panel (MF8
and MF12 also in the rear panel) and the fan, placed in the rear panel (only for MF16 and
MF24) should be free, so that the air circulates freely, and the amplifier could have a better
heat dissipation. In the same way, make sure that there are no heat sources near the front
cooling vent, because the fan exhaust cool air through this vent.
Also, the mains transformer of the models MF16 and MF24, has a cooling vent in the left
side of the power amplifier. This cooling vent may correspond with another one in the rack.
CHANGING THE FUSE
The power amplifiers are designed to work with slow blow fuses of 6x32, whose values
in order to work with a mains voltage of 230V 50-60 Hz are specified in the following list:
MODELS
FUSE (230V. 50-60 Hz)
MF8
T8A.
MF12
T12A.
MF16
T16A.
MF24
T20A.
Make sure that the power amplifier is disconnected from the mains.
At the power amplifier rear panel is placed the fuse holder. Unscrew the most external
part of the fuse holder.
Upon unscrewing the most external part of the fuse holder, the fuse will appear. Re-
move it and change for new one.
Screw the external part of the fuse holder.
CAUTION:
Always make sure upon changing the fuse, that this is the adequate.
CONNECTING TO THE MAINS
The connection of the power amplifier to the mains takes place by means of a three-
wire cord provided by the factory. The European standard color code is: Brown-Live, Blue-
Neutral and Yellow/Green-Earth, keeps in mind this mains configuration, whenever handle
the power amplifier plug.
