re-optimise the amplifier for maximum power delivery at this
higher impedance.
NOTE:
In
the U.S. and Canada the switch may already
have been pre-set for 8-ohm operation, as indicated by an
orange marker directly below the
"80
" label. If you are using
4-ohm speakers, or two pairs of speakers wired
in
parallel,
you should re-set the switch to 4 ohms by sliding the screw
heads
to
the right
in
the following procedure.
Before re-setting the
Impedance Selector, tum down the
Volume or switch off the Power. Now, in order to prevent the
Impedance switch from being re-set unintentionally,
it
is
held
tightly in place by screws located to the left and
right of the
switch handle.
Turn
the screws slightly counter-clockwise to
loosen them.
(DO NOT REMOVE the screws!) Note that the
screws are
installed in slots so that they can be moved to the
left
or
right, and
an
orange marker visible through one of the
slots identifies the setting of the switch.
To
set the switch at 8 ohms, slide the screw heads to .
the left end of their respective slots so that the orange

marker becomes visible under the "

(To
re-set
it
for
4 ohms, slide the screw heads
to
the right end of the slots.)
Finally, re-tighten the screws.
If the impedance switch
is
set to 8 OHMS when you are
using low-impedance speakers, or with two pairs of speakers
connected, the receiver may overheat when operated at high
volume levels. Prolonged abuse of this kind could cause
internal fuses to blow in order
to
protect the receiver, in
which case you would have to return the receiver to your
dea
l
er
for
service
.
8. AC POWER CORD. After you have completed mak-
ing connections to the speakers and to other system compo-
nents, plug the AC power cord into a
"live" wall socket.
9.
UNSWtTCHED AC OUTLET. (Not in U.K. model.)
The AC power line cord of another stereo component, such
as
a turntable or tape deck, may be plugged into this acces-
sory outlet. This outlet remains
"live" as long as the receiv-
er's power cord is plugged into a
wall socket.
