SECOND AMPLIFIER AX20 LEFT SPEAKER G 8 16 A 8 G 8 I6 SPEAKER RIGHT SPEAKER TO AUX INPUT OF SECOND AMPLIFIER O LEFT CHANNEL OUT SPEAKER HOOK UP OF AX20 AS STEREO AMPLIFIER IN CONJUNCTION WITH ANOTHER AMPLIFIER Figure B Connecting Both Amplifiers For Stereo Operation: Connect a shielded lead of any length up to 20 feet between the LEFT CHANNEL OUT jack on the rear of the AX20 and the AUX or TUNER input on your other amplifier. Nom: If the amplifier used for the second stereo channel is a combination AMFM tuner, amplifier and preamplifier such as the Harman-Kardon Festival, this connection will not interfere with normal Monaural AM or FM reception through the speaker connected to the combination unit. If you wish to use both amplifiers and speakers for monaural program material, a simple change in the internal wiring of the receiver can easily be made. The change (which is best done by a technician) consists of removing the wire from the Function Selector switch arm (refer to your original instruction book) and extending it out from the chassis. This-wire is connected to the AX20 LEFT CHANNEL OUT Receptacle. A new shielded wire is connected between the Function Selector switch arm and the TUNER Receptacle of the AX20. IMPORTANT: Connect the AC power cord from your monaural amplifier to the AC convenience outlet on the rear of the Model AX20. The on/off switch on the AX20 will now control the power for both amplifiers. Connecting Your Stereo Tuner: The FM output of your Harman-Kardon stereo tuner should be connected to the LEFT TUNER input jack located on the rear panel. The AM output should he connected to the RICHT TUNER input jack. The same method of installa- tion applies if you are using separate FM and AM tuners. Plug the AC line cord of your tuner into one of the AC convenience outlets located on the rear panel of the Model AX20.

Nom:
If
the
amplifier
used
for
the
second
stereo
channel
is
a
combination
AM
-
FM
tuner,
amplifier
and
preamplifier
such
as
the
Harman-Kardon
Festival,
this
connection
will
not
interfere
with
normal
Monaural
AM
or
FM
reception
through
the
speaker
connected
to
the
combination
unit.
If
you
wish
to
use
both
amplifiers
and
speakers
for
monaural
program
material,
a
simple
change
in
the
internal
wiring
of
the
receiver
can
easily
be
made.
The
change
(which
is
best
done
by
a
technician)
consists
of
removing
the
wire
from
the
Function
Selector
switch
arm
(refer
to
your
original
instruction
book)
and
extending
it
out
from
the
chassis.
This
-wire
is
connected
to
the
AX20
LEFT

Receptacle.
A
new
shielded
wire
is
connected
between
the
Function
Selector
switch
arm
and
the
TUNER
Receptacle
of
the
AX20.
IMPORTANT:
Connect
the
AC
power
cord
from
your
monaural
amplifier
to
the
AC
convenience
outlet
on
the
rear
of
the
Model
AX20.
The
on/off
switch
on
the
AX20
will
now
control
the
power
for
both
amplifiers.
Connecting

located
on
the
rear
panel.
The
AM
output
should
he
connected
to
the
RICHT
TUNER

jack.
The
same
method
of
installa-
tion
applies
if
you
are
using
separate
FM
and
AM
tuners.
Plug
the
AC
line
cord
of
your
tuner
into
one
of
the
