Antenna Connections

FM ANTENNAS
FM Indoor Antenna
If you live reasonably close to a transmitter and want
to use the provided lead-type FM antenna, you will
connect it directly to the "FM 75 W" socket at the
back of the main unit. See the LOCATION OF JACKS
AND TERMINALS page for details on the location of
this socket. Fit the metal sleeve of the lead-type antenna
over the core (center) conductor of the (FM 75 W)
socket. Be sure to fully extend the FM antenna and keep
it as horizontal as possible.
Lead-type FM Antenna (75 W provided)
Outdoor FM Antenna (75 W)
FM Outdoor Antenna
In an area where FM signals are weak, it will be
necessary to use a 75 W unbalanced-type outdoor
FM antenna using the optional matching transformer,
as shown. Generally, a 3-element antenna will be
sufficient, if you live in an area where the FM signals
are particularly weak, it may be necessary to use one
with 5 or more elements. Check the instructions provided with
the outdoor antenna for details on how to connect it to this
product.

AM Indoor Loop Antenna
To stand the antenna on a surface, fix the claw to the
slot.
A high-performance AM loop antenna provided with the
receiver is sufficient for good reception in most areas.
Connect the loop antenna's wires to the AM antenna
terminals as shown. Place the antenna on a shelf, for
example, or hang it on a window frame, etc., in the
direction which gives the best reception. Place it as
far away as possible from the entire system, speaker
cords and the power cord, to prevent unwanted noise.
AM Outdoor Antenna
If the provided AM loop antenna does not deliver
sufficient reception (because you are too far from the
transmitter or in a concrete building, etc.), it may be
necessary to use an outdoor AM antenna. Check the
instructions provided with the outdoor antenna for details on
how to connect it to this product.
Note: when connecting an outdoor AM antenna, do not
disconnect the AM loop antenna.
