SPEAKER CONNECTION
This amplifier has provision
for two pairs of speaker systems—
system
A and
system
B which
can
be selected
individually
by
means of the front panel SPEAKERS
selector.
Caution
This amplifier is rated at 90 watts minimum
RMS per channel with
an 8-ohm load from 20 - 20,000 Hz and may deliver an instantane-
ous peak power much greater than the rated power.
Be sure to use
speakers
with
adequate
power
handling
capabilities.
Always
reduce the volume, when
setting down
or removing a tonearm
or
when
tuning an fm tuner across the band.
Speaker damage may
result if these precautions are not observed.
Speaker impedance
This
amplifier
is designed
to work
best
with
speakers
having
nominal ratings from 8 to 16 ohms.
Care should
be taken that the speaker impedance
should not be
less than the lowest indicated value (8 ohms) on the rear panel.
Speaker cable type
The type of wire used to connect the speakers to the amplifier is
not critical in most home stereo systems.
Common
18-gauge lamp cord (the center conductor of 1mm
in
diameter)
is fine for short runs.
However,
16-gauge
(1.3mm)
to
14-gauge
(1.6mm)
may
be needed
for long
runs
to prevent
ex-
cessive power losses in the wiring.
