Preparing
for
projection
Place
projector
with
sound head unit on the
amplifier
in
such
a
way
that the
control
panels
are
on the same
side
(Fig. 1
).
The
feet
of
the
projector
are
placed
in
matching
recesses
provided
in
the
top
face
of
the
amplifier
housing. Initially there
is
a
distance
wPf
about
2
cm
between
the plug term1nals
61
of the
amplifier
and the front
edge
of
the
projector
base.
Push
the
projector
forward
towards
the terminal strips until the latch
63
snaps
audibly
into the recess at the back
edge
of
the
projector
base
(To
unlatch,
depress
button 64).
Before
inserting the plug
of
the supply
cable
of
your
2000
sound
projector
in
the
mains socket, check the
voltage
and
type
of
current
of
your
mains supply. You
will
fmd
the
relevant
information on the
electricity
meter. The sound
projector
may
only
be
connected
to
A.
C.-mains
(-).
The
series
resistance
in
the
projector
should
corre-
spond to the
selected
lamp and the supply
voltage
available. Set the
voltage
selector
(Fig.
3)
on the
top
surface
of
the
amplifier
accordingly.
If the value
indicated
on the
voltage
selector
does
not
correspond
to
the mains
voltage,
its setting must
be
alter-
ed.
To
do
so, first
unscrew
the fuse
element
a.
Then pull the contact ring b from its
holder
and turn it until the figure
appearing
in
the lateral cutout
corresponds
to the mains
voltage.
Before
re-inserting the fuse
ele-
ment, check
whether
the fuse has the ap-
propr1ate rated
value A 200-mA fuse is
suitable
for
220
to
240-V
supply
voltages
while
a 400-mA fuse
is
intended
for
110 to
130-V
supply
voltages.
A
replacement
fuse
will
be
found on the
underside
of
the ampli-
fier.
Owing
to a
special
overvoltage
protection
device,
incorrect
setting
of
the
voltage
selector
will
not result
in
an
undue increase
of
the transistor
operating
voltages
and the
attendant
destruction
of
the transistors. Ref-
erence
is
also
made
to the remarks on
pp
3-6
of
the main instruction manual.
To
connect
the
loudspeaker,
uncoil the
cable
provided
in
the
carrying
case and
connect
the plug
with
socket
74
of
the
amplifier.
Place the
cable
in
such
a
way
that
nobody
can trip
over
it. Do not
place
the
loudspeaker
behind the
projection
screen but
arrange
it
in
a
somewhat
raised
position,
adjacent
to the screen. Any
port-
able
loudspeaker
supplied
for
use
with
Siemens sound
projectors
may
be
used,
except
No.

When using any other make, make sure that
the unit
employed
is
a 15-ohm
loudspeaker
.
If you wish to fill
projection
intervals
with
music from records,
connect
your
record
player
to the socket
66.
A
low-
i
mpedance
microphone
may
be
connected
to socket
65.
