CONNECTING ANTENNAS
FM INDOOR ANTENNA
In an area with strong FM signals, the “T”-type FM antenna provided is sufficient.
Extend this into a “T” shape and connect the two wires at the base of the “T” to the provided matching
transformer, as shown. After completing connection, plug the transformer into the “FM 75Ω“ socket.
Extend the top of the “T” and fix with thumb tacks, or the like, to a wall or window frame for the best
possible reception.
FM OUTDOOR ANTENNA
In an area where FM signals are weak, it will be necessary to use a 75-ohm unbalanced-type outdoor FM
antenna. 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
1 Strip the cable and dress it as shown.
2 Press both side tabs outward to remove the cover.
3 Wrap the core conductor around the central metal fixture as shown. Crimp the jagged metal fixtures
so they hold the braided portion using pliers, etc. Put the cover back in place.

CONNECTING ANTENNAS
AM INDOOR LOOP ANTENNA
The 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, as far away as possible from the entire system, speaker cords and the power cord, to
prevent unwanted noise.
AM OUTDOOR ANTENNA
If the AM loop antenna provided 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.
Use an insulated wire more than 15 ft (5 m) 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
Even when using an outdoor AM antenna, do not disconnect the AM loop antenna.
AM Loop Antenna (provided)
CAUTION
To avoid damage the speakers by inputting a sudden high-level signal, be sure to switch the power off
before connecting the speakers.
Connect the cable from each speaker to the corresponding terminal on the rear of the receiver.
• Most speaker cables have different markings, textures or colors to help you tell the difference between
negative and positive.
• Be sure to connect the positive (+) terminal on each speaker to the positive (+) terminal on the receiver.
Similarly, connect the negative (-) terminal on the speaker to negative (-) terminal on the receiver.
NOTES
• Use speakers with a nominal impedance of 8 ohms or more.
HOW TO CONNECT
1 Strip back the cable covering by about 1 cm and twist the wire strands together.
2 Turn the terminal cap counterclockwise to loosen it. The speaker terminal caps cannot be fully removed
from the base.
