- RADIO RECEPTION
The quality of reception that can be expected from
the 350A is largely dependent on the correct posi-
tioning and use of antennas.
The following proce-
dures are recommended for noise-free reception.
FM Antenna
Where FM broadcasting stations are near and FM
signals are strong, satisfactory FM reception can be
obtained by using the feeder wire accompanying
the amplifier. Connect the feeder wire to the an-
tenna terminals marked
FM 300,0,-Al and A2 on
the rear panel, then fully extend
the wire to a T
form and
fix it to a wall or ceiling where it allows
the strongest reception.
If the 350A is used in a thick-walled building or in
an area remote from FM broadcasting stations, the
indoor feeder wire antenna may be inadequate for
strong signal reception.
An outdoor antenna de-
signed exclusively for
FM reception should then be
installed.
FM antennas for the 300-ohm balanced type and
75-ohm unbalanced type can be used with the
350A. Connect either
antenna to the matching
antenna terminals on the rear of the amplifier.
The
300-ohm feeder wire should be connected to the
antenna terminal marked
FM 300,0,-Al and A2. If
the 75-ohm coaxial cable is used, connect the con-
ductor to
the antenna terminal marked FM 75,0, - Al,
and the shielding wire to the terminal G.
NOTE: FM sensitivity cannot be raised simply by
lengthening
the antenna. Adjust the antenna's
height and direction while actually listening to a
broadcast for the best reception.
Built-in AM Ferrite Bar Antenna
This sensitive antenna, located on the rear panel of
the amplifier, is usually adequate for AM reception.
To use, pull it down and away from the back of
the amplifier until it comes to a stop halfway between
the top and the bottom of the amplifier.
Then
move it from up to down until best reception is
obtained.

Outdoor AM Antenna
In ferroconcrete buildings or in areas remote from
the broadcasting station, the built-in ferrite bar
antenna may be inadequate for
AM reception. An
outdoor antenna then becomes necessary. This can
be accomplished by connecting the
PVC wire ac-
companying
the amplifier to the antenna terminal
marked
AM-Al on the back panel. Run this wire
to an antenna
that has been installed outdoors and
away from the building.
At the same time, the unit.
should be grounded. Adjust the outdoor antenna for
maximum signal pick-up, while actually receiv
in g
a broadcast. And, for reasons of safety, be sure to
attach a lightning arrester to the outdoor antenna.
To Listen to Monophonic
FM Programs
1. Set the SELECTOR switch to the FM AUTO
position.
2. Keep the MODE switch in either MONO or
STER EO position.
3. Turn the TUNING knob to select the desired
station. Once selected, adjust it so that the needle
of the T U
NING meter moves as far to the right as
possible.
4. Use all other controls and switches according to
your taste and listening conditions.
To Listen to FM-MPX Stereo
Programs
1. Set the SELECTOR switch to the FM AUTO
position.
2. Set the MODE switch to STEREO.
3. Select the desired FM stereo station with the
TUNING knob and pinpoint the station with the
TUNING meter. If the dial pointer crosses a sta-
tion broadcasting
MPX stereo, the FM STEREO
indicator will light up.
4. Adjust the BALANCE control for equal sound
from both right and left channels.
5. Use all other controls and switches according to
your taste
and listening conditions.
