Speakers
If only set of speakers is to be connected, make connections
to the terminals marked SPEAKERS A.
Connect the speakers to the [D and [0 terminals in accor­
dance with the location selected for each speaker. To en­
sure correct speaker phasing, observe polarity mark; con­
nect terminals marked + on the receiver to similarly-marked
speaker terminals. Do the same for receiver and speaker
terminals marked with a minus sign. Reversal of speaker
leads will result in loss of bass tones and poor stereo separ­
ation.
If a second set of speakers is to be used, make connections
at the right set of terminals, marked B. A third set of
speakers may be connected to the terminals marked C.
Impedance selector switch
The switch on the rear panel is set in the factory to the "8i2
OR MORE" setting. However, this switch must be set to the
correct setting according to the total impedance of the
speakers to be operated. Follows the instructions below to
set to the correct setting.
1. When a pair of speakers is to be used independently with
the speakers connected to the A, B and C terminals, set
the switch as follows:
Less than 8i2 - When a pair of speakers is to be used,
each speaker should have a rated impedance of 4
ohms.
8Q or More - When a pair of speakers is to be used,
each speaker should have a rated impedance of 8 or
16 ohms.
2. When two pairs of speakers connected to the A and B (or
C) terminals are to be operated in combination, set the
switch as follows:
Note:------------------------------- ^-------------------------------------------
Speakers rated at 4 ohms should not be used.
