Teac AG-500 - Precautions; Placement of the Unit; Antenna and Speaker Connections

Precautions
Placement of the Unit
As the unit incorporates a powerful
amplifier, heat is radiated from the back
and top of the unit; the location where the
unit is installed should be well ventilated.
Avoid installing where it would be exposed
to high temperatures, direct sunlight, high
humidity and dust. If the wiring is too long,
particularly the speaker connections, it
may result in degraded sound. Keep the
connection cables as short as possible.
Antennas and Speakers
FM Antenna
If the AG-500 is used in an area with strong
FM signals, a “T” type antenna (dipole)
may provide a sufficiently strong signal. To
connect this antenna, attach the leads to
the 300-ohm terminals, fully extend the
upper sections of the “T” and position it
for the optimum reception when tuned to a
broadcast.
In a weak signal area, the use of a roof-top
FM antenna is recommended. A 3-element
antenna is generally sufficient for medium
distances and a 5-element or better
antenna may be required for longer
distances and in fringe areas.
Two types of outdoor antenna are
available, 300-ohm balanced and 75-ohm
unbalanced antennas. 300-ohm antennas
use a flat twin-lead cable, similar to a
standard TV antenna. 75-ohm antennas
use a coaxial cable and these are
recommended for use in areas subject to
interference such as near a road where
car ignition noise is a problem. After
installing a roof-top antenna, check that it
is pointing in the direction from which
most stations are received.
FM antenna connection
When connecting 300-ohm antenna leads,
slide the lugs under the terminals marked
“300 ohm”.
To install a 75-ohm coaxial cable, first strip
the covering of the cable, insert under the
clamp so that the clamp is in contact with
the shielding, wrap the core wire around
the “75 ohm” FM antenna terminal, then
tighten the knurled knob, as shown in the
diagram at the top of the next column.

AM Antenna
AM loop antenna
The AG-500 is equipped with a high-
performance AM LOOP ANTENNA
attached to the rear panel by a snap-in
hinge.
In areas where signals are strong or near
broadcast stations, the AM loop antenna
on the rear panel may be sufficient. This
antenna is effective except in areas where
the signal strength is very low, or in a
concrete building. Position this antenna
so that the broadcast is heard most clearly
when tuned to an AM broadcast. The AM
loop antenna can be detached and
removed from the antenna holder then
hung on a window, wall, etc., wherever
reception is best.
AM loop antenna connection
Securely connect the loop antenna leads
between the AM and GND ANTENNA
terminals of this unit.

Outdoor antenna
When having difficulty receiving AM-
broadcasts clearly with the AM loop
antenna, an insulated vinyl wire longer
than 15 ft. can be connected to the AM
antenna terminal and set near a window or
as high outdoors as possible.
AM outdoor antenna connection
The insulation should be stripped off the
end of the antenna wire which should then
be connected to the AM terminal. Connect
another wire between the AM GND
terminal of the unit and a reliable ground.
Note: Do not disconnect the AM loop
antenna leads at this time.
Speakers
Note: Be sure to use speakers having an
impedance of 8 ohms or more.
Connect the main pair to the system A
terminals, and connect the second pair to
the system B terminals. Connect the
speaker cables to the speakers A/B
terminals as shown in the diagram.
* Press the lever, insert the stripped
end of the cord, then release the
lever so that the cord is held securely.
