4.
Arrange the speakers so that the distance between them is
about 2/3 the distance to the listener. Too little distance
between the speakers is better than too much.

When listening to a mono speech program switch over to
one speaker by using the BALANCE control
Speaker selector
The speaker selector switch marked SPEAKERS has six
positions as follows:
OFF:
All speakers disconnected
A:
Program to speaker outputs A only
A+B:
Program to speaker outputs A and B only
B:
Program to speaker outputs B only
A+C:
Program to speaker outputs A and C only
C:
Program to speaker outputs C only
In all positions of the speaker selector the program is also fed
to the PHONES outputs.
NOTE!
It is not possible to feed all three speaker outputs at the same
time.
Output power indicator
Depress the button POWER READING on the
lower left of the front panel to obtain an indication on the
SIGNAL meter of the audio power being delivered to the
speakers.
The meter is peak reading, and indicates output voltage for
the left or right channel, whichever momentarily has the
highest output. Maximum obtainable output power depends
on the speaker impedance (load per channel). The table shows
the relation between output power and meter reading at
different load impedances.
The output monitoring function of the meter serves two
purposes:
—
To avoid overloading the output amplifier,
—
To avoid overloading speakers not rated for the full output
power of the amplifier,
NOTE
:
If the receiver is overloaded at too high ambient temperature
(insufficient ventilation), a thermal switch will disconnect the
amplifier. The amplifier will, however, resume normal
operation as soon as the temperature inside the receiver has
dropped sufficiently.
