Figure 4. AM Ferrite-rod Antenna
ANTENNA ATTENUATOR
The ANTENNA ATTENUATOR can be switched
into or out of the antenna circuit. Use the AN
TENNA ATTENUATOR switch in the "IN"
posi
tion only when overloading is apparent from
reception of one station at several points of the
dial and is affecting reception of a desired station.
Overloading may also cause severe distortion which
will not disappear with proper antenna orientation.
(Note: With the ANTENNA ATTENUATORswitch
"IN," the FM sensitivity and the number of
stations that can be received are reduced.)
AM ANTENNA
Your Receiver is equipped with an AM ferrite-rod
antenna. BEFORE USING THE MODEL 2270,
PULL THE ANTENNA AWAY FROM REAR PA
NEL AS SHOWN IN FIGURE 4.
The ferrite-rod antenna will give you satisfactory
results to primary signal areas. However, an
out
door antenna will provide better reception in rural
areas. Two single wires are required to make an
AM outdoor antenna. First, connect one end of a
single wire to the AM antenna terminal on the rear
panel, and the other end at a very high position out
doors (the higher the better,) or swing it from the
window of your room. Next, connect the other sin
gle wire between the "G" (GROUND) terminal of
your Model 2270 and an earth ground (such as a
water pipe.)
CONNECTION TO AC OUTLET
With the front panel power pushswitch "out,"
plug the line cord into an electrical outlet supplying
the proper voltage.
CAUTION: DO NOT PLUG YOUR MODEL 2270
INTO A DCOUTLET SINCE SERIOUS DAMAGE
WILL OCCUR.
CONVENIENCE OUTLET
One UNSWITCHED and one SWITCHED AC
OUTLET are provided on the rear panel for
powering associated components of your system
(tape recorder, record player, etc.).
SIMPLIFIED OPERATING PROCEDURE
When operating the Model 2270 Stereo Receiver
for the first time, follow these simple directions.
Later, full advantage can be taken of its versatility
with the remaining controls and pushswitches.
Step 1. Connect the FM antenna to the appro
priate terminals on the rear panel.
Step 2.
Connect the speakers to the MAIN
speaker terminals.
Step
3.
Check that all pushswitches are in the
"out" position. Pushswitches in the
"in" position should be depressed
for releasing to the "out" position.
Step 4.
Turn the volume control all the way
to the left (counter clockwise) and
set the balance control in mid-position
(pointer to dot at 12 o'clock).
Step 5.
Rotate treble, mid, and bass controls
to the 12 o'clock position (each pair
of pointers to dot).
Step 6.
Set MAIN Speaker pushswitch "in,"
and REMOTE "out" (assuming your
loudspeakers are connected to the
MAIN amplifier terminals)
.
Step 7. Turn on system power by depressing
the power switch.
Step 8.
Select the desired program source
by setting the selector switch to the
appropriate
position.
If FM or AM
is selected, rotate the Gyro-Touch
