The two SPEAKER SELECTOR switches located on the front panel are inoperative for this method of connection, and their setting is therefore not critical. IMPORTANT: For all methods of stereo operation, the SEPARATE-PARALLEL switch mounted on the front chassis support apron directly behind the pilot light must remain in the "SEPARATE" position. The cage (if used) must be removed to provide access to this switch.

Remove the shorting bar between A and B terminals on both SPEAKER out- put strips. Connect a lead from the left speaker in System A to the 16 ohm terminal on the LEFT SPEAKER OUTPUT strip and another lead from this speaker to the A terminal on the same strip. Connect the right speaker in System A to terminals 16 and A on the RIGHT SPEAKER OUTPUT strip. This completes Sys- tem A installation. To install System B connect a lead from the left speaker to the 16 ohm terminal on the LEFT SPEAKER OUTPUT strip and another lead to the B term- inal on the same strip. Now connect the right speaker in System B to the 16 and B terminals on the RIGHT SPEAKER OUTPUT strip. This completes System B installation. (See Diagram B) The above illustration is for 16 ohm speakers. If you are using 8 ohm speak- ers connect to the 8 ohm terminals on the SPEAKER OUTPUT strip rather than to the 16. If one pair of speakers is 8 ohms and the other pair 16 ohms, then connect appropriately. For this type of installation the SPEAKER SELECTOR switches located on the front panel are operative. See Stereo Operating Instructions. IMPORTANT: The SEPARATE-PARALLEL switch located on the front chassis support apron directly behind the pilot light must remain in the "SEPA- RATE" position. The cage (if used) must be removed to provide access to this switch.

term-
inal
on
the
LEFT
SPEAKER
OUTPUT
strip
and
another
lead
from
this
speaker
to
the
A
terminal
on
the
same
strip.
Connect
the
right
speaker
in
System
A
to
terminals
16
and
A
on
the
RIGHT
SPEAKER
OUTPUT
strip.
This
completes
Sys-

A
installation.
To
install
System
B
connect
a
lead
from
the
left
speaker
to
the
16
ohm
terminal
