Connection Guidelines
Before Making Connections
It
is
always
wise
to
ensure
that
all
AC
power
cords
of
the
various
components
that
you
are
interconnecting
are
unplugged
from
the
wail
outlets
during
the
hook-
up
process.
This
will
prevent
any
inadvertent
damage
to your
speakers
or
receiver
from
incorrect
control
settings
or
connections.
interconnecting Leads
Be
sure
that
left
and
right
channel
identification
is
correct
when
making
interconnections.
Most
patch
cords
are
colour
coded
with
RED
ends
for
the
right
channel
and
BLACK
or
WHITE
ends
for
the
left
channel,
to
make
this
job
easier.
In
addition,
all
jacks
on
the
rear
of
the
R-341
have
red
centres
for
right
channel
and
white
for
left
channel.
When
making
connections,
follow
the
Reference
ilustrations
referring
also
to
the
descriptions
for
items #41 through #55 on pages 11 and 12.
Speaker Connections
The following items should be observed carefully
when connecting your speakers.
1. Be sure PHASING is correct by connecting the
RED (+) and the BLACK (-) terminals of the
R-341 to the RED (+) and BLACK (-—) terminals of
your
speakers
on
each
channel.
Failure
to
do
so
will result in drastically reduced bass response
and unstable, irregular stereo imaging.
no
. To prevent the possibility of shorts, strip back the
ends of the speaker leads about 1/2 inch and
carefully twist the strands together. Loosen the
speaker terminal knob by rotating it
counterclockwise. Insert the twisted end and turn
the knob clockwise to tighten.
Inspect carefully to ensure that no frayed strands
exist that may cause shorts.
3. It is recommended that 16 AWG gauge wire, or
larger, be used to prevent losses. You may wish
to consider some of the commercially available
speaker cables that are specifically designed to
improve the receiver to speaker interface.

R - 341 |
[AM Antenna |
An AM loop antenna comes packed with your R-341.
Carefully unwrap and mount it to the rear panel and
connect leads.
FM "T" Type Antenna
included also with your R-341, is an FM "T" type
antenna. This type of antenna is simple and practical
and
will
give
adequate
results
in
primary
signal
areas.
To use it, unfold it and connect its centre leads to the
DIN type connector on the rear of the receiver, using
the 300 ohm to 75 ohm adapter. The antenna is
designed
to
operate
in
a
horizontal
position,
and
may
be attached to a nearby wall.
The R-341 is also capable of accommodating other
types of cable, including 75-ohm coaxial cable (with
DIN type connector). These types of cable are for use
with outdoor antennas, which will be discussed next.
Outdoor FM Antenna |
As stated before, the supplied folded FM "T" type
antenna
will
give
satisfactory
results
in
primary
signal
areas. However, if you are located in a fringe area
where
signals
are
weak,
then
an
outdoor
antenna
will
be necessary. Even if you live in a strong signal
location, an outdoor directional antenna may be
needed to eliminate "multipath" reflections.
Multipath reflections are responsible for much of the
distortion and noise associated with poor FM recep-
tion. They occur when radio waves from the transmit-
ter bounce off of nearby mountains and tall buildings.
The reflected waves follow different, more round-
about paths to your tuner and arrive slightly delayed
and out of phase with the direct signal (hence, the
term "multipath"). This causes distortion in the same
manner that “ghost" images are generated on televi-
sion.
The way to minimize multipath is to use a "beam type"
antenna that can be aimed toward the FM transmitter
and away from the multipath reflections. The best
types of antennas to use are either a "Yagi" or "Log-
Periodic” configuration with six or more elements
designed expressly for FM reception.
If you want to receive stations from more than one
general direction, then you will need a good quality
antenna rotor system. This will enable you to point the
antenna in the direction giving the least multipath
interference, by means of a control box located near
the receiver.

(or 75 ohm coaxial
cable where applicable)
Rotor Unit
Rotor Control
Cable
Guy Wires
(Use 4)
Ground Wire
for Steel Mast
Another important factor is the type of lead-in wire to
use.
Unshielded
lead-in
wires,
such
as
300-ohm
twin
lead, can act as an omnidirectional antenna, and can
cancel the directional benefit of your antenna.
Therefore, we recommend using a coaxial 75-ohm
cable at the antenna. This shielded cable effectively
prevents the lead-in from contributing to multipath
distortion.
if
you
decide
to
use
75-ohm
coaxial
cable,
we
recom-
mend
buying
cable
with
DIN
type
connectors
at-
tached.
These
will
fit
the
FM
(75
ohm)
terminal
on
the
R-341.
It
is
considered
good
practice
to
connect
the
antema
mast
to
an
earth
ground,
both
for
reasons
of
safety
and
noise
reduction.
For rural areas, it is recommended to consult a local
dealer
about
installation
and
lightning
arrester
protec-
tion.
We don’t recommend using master antenna systens,
such
as
those
found
in
flat
buildings.
Such
systems
are
usually
designed
expressly
for
television
recepion
and frequently suppress or reduce the quality of the
FM signals before distribution.

"POWER" button
Pressing this button turns the unit on and off,
along with other equipment that may be plugged
into the rear panel switched AC outlet.
. "stand-by" indicator
Lights up when the power button is turned off to
show that the remote system is ready to receive a
power ON command.
. "station presets" buttons
A total of 20 AM (LW/MW) and/or FM stations may
be placed into memory in any random order and
recalled for instant play, with these buttons.
Select previously stored preset stations by press-
ing the desired number 1 through 10. For presets
11 through 20, press the +10 button first, then 1
through 10. Each number thus selected will appear
in the display just under the words "STATION

This display window shows the frequency of tuned
AM (LM/MW) and FM stations. In addition, the
station preset number, currently selected from
memory, is displayed to the right of the station

"remote sensor"
When using the hand held remote control, it must
be pointed toward this sensor to activate opera-
tional functions.
"loudness" button
Depressing this button introduces a moderate
boost of the very low and high frequencies when
the volume ccntrol is set below the half-way
position. This compensates for the human ear’s
characteristic at low listening levels.
"balance" control
Adjusts for unequal volume level between chan-
nels. Normally, with today’s high quality sources,
it is seldom necessary to move this control from
its precision centre detent position.
"treble" control
This control will increase or decrease high
frequency content in the program material. At the
centre detent position, a flat frequency response
results.
13. “bass" control
This control will increase or decrease low fre-
quency content in the program material. At the

Operation Guidelines
The following guidelines assume that all connections
have been made according to the "Reference Illustra-
tions".
Power and Source Switching
To prevent the possibility of excessive, sudden sound
levels, it is recommended that the volume control be
placed at a low level position each time the power
button is turned on or when switching between
sources by the INPUT SELECTOR.
Tape Recording Operations
To make a tape recording of any source, proceed as
follows:
1. Press the input Select button (item #6) for the
source you wish to record.
2. Rotate the “REC OUT SELECTOR?” (item #15) to
the “source” position.
3. The source signal will now be fed to the tape deck.
Follow the recording instructions for the tape deck
in use.
4. If you have a 3 head deck, you.can monitor the
actual recording by depressing the “tape monitor”
button (item #6) on the R-341.
5. When recording from a CD player, use the CD
position. This allows you to listen to any other
source while recording a CD.
Tape Playback
1. Press the “tape monitor” button (item #6).
2. Operate the tape deck.
FM/AM Tuner Operations
The R-341 incorporates several tuning methods to
provide ease, yet great flexibility in station selection
and use. Proceed as follows:
Auto Tuning
