INPUT CONNECTIONS
CONNECTING the FM ANTENNA
The antenna input has been designed to accept either a 300 ohm balanced
transmission line (300 ohm twin lead) or a 75 ohm unbalanced co-axial cable
transmission line.
Due to the exceptionally high sensitivity of your receiver, a 48" wire
is sufficient for all but the most difficult locations. When using the 48" antenna,
connect one end of the 48" wire to either PM antenna terminal. Horizontal
placement of the antenna will yield optimum reception. The antenna may be
tacked to the back of the molding behind the equipment or to the shelf you use.
As FM signals are in the same broadcast frequency range as TV signals,
they are affected by the same external conditions. Just as TV reception is im
proved, you can improve your FM reception with an external antenna. When
using an external antenna, connect both leads of the antenna wire to the two
300 ohm FM antenna terminal posts on the rear of your receiver.
When using a 75 ohm Coaxial Cable connect between the 75 ohm and
GND terminal, with the outer conductor or shield of fhe cable connected to
the GND terminal.
CONNECTING THE AM ANTENNA
The AM loopstick fastened to the rear of your receiver comprises all the
antenna usually required for normal signal areas. In more remote locations an
additional outdoor antenna may be required. This should consist of a single wire,
as long as is reasonably practical. It must be kept away from large metal objects,
power lines or electrical machinery to insure reception without extraneous noise.
Attach this length of wire to the AM terminal of the ANTENNA terminal strip.
PREAMP OUT AND AMP IN RECEPTACLES
These receptacles are intended for use with any necessary equipment de
signed to be installed between a preamplifier and power amplifier. This includes
such equipment as electronic audio equalizers, reverberation units, and a new
quadraphonic processor offered by Harman-Kardon. In order to make use of
this facility, simply disconnect the two patch cords connected to these receptacles
and follow fhe instructions supplied with the accessory equipment.
NOTE: When no accessory equipment is being used, the two patch cords
MUST be installed in order to use your receiver.
PHONO 1 and PHONO 2
There are two sets of low level phono receptacles on the rear panel of
your receiver. They are designed for use with any magnetic pickup with a
nominal impedance of 42,000 to 52,000 ohms.
This special convenience permits you to connect a record changer and a
manual turntable simultaneously, and to switch between them with the function
selector located on the front panel. Since both low level inputs are identical and
each has been compensated for the RIAA recording curve of today's modern
recordings, either or both may be used.
When connecting a stereo record player (magnetic pickup) connect both
leads to either the Phono I or Phono 2 LEFT and RIGHT input receptacles on
the rear of the receiver chassis. When connecting a monophonic record player
(magnetic pickup) connect the single lead to either the Phono 1 or Phono 2
LEFT or RIGHT input receptacle.
GROUND CONNECTION
Under certain conditions it may be necessary to provide a common "ground"
between your receiver and your other associated equipment. This may be ac
complished by using the GND terminal located on the rear panel of your receiver.
AUX INPUTS
Your receiver has two pair of AUX INPUT receptacles for use with high
level program sources; ceramic or crystal pickup, reel-to-reel tape recorder,
cassette tape recorder, TV or a second stereo tuner.
When connecting a stereo record player (ceramic pickup) connect both
leads to either the AUX 1 or AUX 2 LEFT and RIGHT input receptacles on the
rear of the receiver chassis. When connecting a monophonic record player
(ceramic pickup) connect the single lead to either the AUX f or AUX 2 LEFT or
RIGHT input receptacle.
When connecting a stereo tape recorder connect both output cables to
either the AUX 1 or AUX 2 LEFT and RIGHT input receptacles on the rear of the
receiver chassis. When connecting a monophonic tape recorder connect the
single output lead to either the AUX 1 or AUX
In order to make a recording connect the input cable (if monophonic) or
cables (rf stereophonic) to either the TAPE OUT 1 or TAPE OUT 2 receptacles
on the rear of the receiver chassis.
TAPE MONITOR 1 and TAPE MONITOR 2
There are two pair of tape monitor receptacles on the rear of your receiver.
Either one or both pair of receptacles may be used to monitor your tapes as you
make a recording, provided your tape recorder or recorders have separate
record and playback heads. Connect the LEFT and RIGHT output cables of your
tape recorder to the TAPE MONITOR 1 or
tion is explained in detail in the paragraph TAPE MONITOR SWITCH.
