COMBINATIONS WITH THE M-25

MULTIPLE AMPLIFIER SYSTEM
Fig. 3 shows a configuration based on two stereo
power amplifiers which are used to drive a pre-
amplifier, crossover network and four special
speaker systems, all of which are separate buys.
The main advantage of the multiple amplifier
system is that it reduces the intermodulation
distortion. It does this by dividing the audible
frequency range and amplifying each of the sepa-
rate frequencies with special stereo amplifiers. The
audible frequency range can be split into two or
three, in which case the resulting systems are
known as 2-way or 3-way multiple amplifier
systems.

MAINTENANCE

Wipe off any dirt or dust that accumulates on the
operating panel or casing with a polishing cloth or
dry, soft cloth. Clear out any dust between the fins
of the radiator with a brush or similar object. Do
not use furniture wax or cleaners. Remember also
to avoid using thinners, benzine, alcohol and any
other volatile chemicals since they will corrode the
panels.
ATTACHING THE NAME PLATE
The M-25's name plate is designed so that it can
be attached to face you, whichever direction the
M-25 is pointing. All you have to do is to turn the
M-25 upside down, and remove the screw fastening
the name plate with a Phillips screwdriver. Then,
attach the plate to that side which you want to
face you. Always remember that the M-25 is a
heavy piece of equipment and so it should be
handled with the greatest of care. Spread some-
thing under it when turning it upside down to
prevent it from being marked.
