CONNECTION
FM INDOOR ANTENNA
If you live reasonably close to a transmitter and want to
use the provided lead-type FM antenna, you will have to
connect it direct to the “FM 75Ω” socket.
Fit the metal sleeve of the lead-type antenna over the core
(center) pin of the (FM 75Ω) socket, extend the lead and
attach it to a window frame or wall with thumbtacks, or
move around the room, where reception is best.

FM OUTDOOR ANTENNA
In an area where FM signals are weak, it will be
necessary to use a 75Ω 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. Connect the coaxial cable of the
antenna to the matching transformer as shown. After
completing connection, plug the transformer into the “FM
75Ω” socket.
How to connect a coaxial cable to the matching
transformer
Strip the cable and dress it as shown.

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, and move
around to obtain the best reception, place as far away as
possible from the entire system, speaker leads and the
power cords, to prevent unwanted noise.

AM Outdoor Antenna
If the AM loop antenna provided does not receive
sufficient reception, it may be necessary to use an outdoor
AM antenna.
Use an insulated cable of a length of 15 ft (5m) long, strip
one end, and connect this to the terminal as shown.
The antenna wire should be strung outdoors or indoors
near a window.
For better reception, connect the GND terminal to a
reliable ground.
Note: When connecting an outdoor AM antenna, do not
disconnect the AM loop antenna.
