Connecting, Your Stereo Record Player: A stereo cartridge is essentially two cartridges in one and uses two ouput connecting plugs. If you are using a low level magnetic cartridge, plug one output lead into the LEFT LO PHONO input jack located on the rear of the chassis and the other cartridge output lead into the RIGHT LO PHONO input jack. Stereo crystal or ceramic cartridges may also be used with this amplifier. They must be plugged into the LEFT and RIGHT HI PHONO input jacks. Plug the AC line cord of your record player into one of the AC convenience outlets located on the rear panel of the Model AX20. Connecting Your Stereo Tape Player: A stereo tape deck utilizes two playback headS. Each head has its own output plug. Connect one plug to the LEFT TAPE IHD input jack and the other plug to the RIGHT TAPE HD jack. These jacks are located on the lower left portion of the rear panel. Connecting Your Stereo Tape Recorder: Since most stereo tape recorders have their own preamplifiers, it is not de• sirable to plug the output of the recorder into the TAPE HD input jacks. This might cause overloading of the input stage. Connect one of the output plugs of your recorder into the LEFT AUX jack and the other output plug into the RIGHT AUX jack located on the rear panel of this instrument. Connecting Your Tape Recorder to Make a Recording: Provision is made on your Model AX20 to permit the recording of any program material. Connect the left input of your stereo tape recorder to the receptacle marked LEFT TAPE OUT on the rear panel and the right input of your stereo_tape recorder to the receptacle marked RIGHT TAPE OUT. To connect a monaural tape recorder, connect its input to either LEFT or RIGHT TAPE OUT receptacle. If the program source you desire to record is plugged into the left preamplifier channel, use the LEFT TAPE OUT jack, and if it is plugged into the right preamplifier channel, use the RIGHT TAPE OUT jack. This will enable you to make a recording with the proper recording equalization as determined by your recorder, while simultaneously monitoring the program with the proper tone control, contour and loudness setting. OPERATING THE MODEL AX20 AS A STEREOPHONIC CONVERTER Every control on a well designed and honestly considered high fidelity instrument has a specific useful function related to each of the other controls. A brief explanatory note on the relationship of the various front panel controls will doubtless prove useful in organizing and clarifying them for you. The Model AX20 incorporates the following front panel controls. Viewing the instrument from left to right you will note a TREBLE control (on/off switch is incorporated in this control), BASS control, LOUDNESS. control, BALANCE control, MODE switch and FUNCTION switch. On the upper section you will note the SPEAKER SELECTOR switch RUMBLE FILTER switch, CONTOUR SWITCH, and EQUALIZATION switch.

Connecting
Your

preamplifiers,
it
is
not
de•
sirable
to
plug
the
output
of
the
recorder
into
the
TAPE
HD
input
jacks.
This
might
cause
overloading
of
the

the
left
preamplifier
channel,
use
the
LEFT
TAPE
OUT
jack,
and
if
