CONNECTING
AUDIO OUTPUTS
Use the FIXED OUTPUT jacks (left-hand
pair of jacks next to OUTPUT ADJ) to connect
to a conventional control preamplifier which
has its own volume control. Full tuner output
is available at all times from the FIXED
OUTPUT jacks.
Use the FRONT PANEL CONTROLLED jacks
to connect to a conventional control pre-
amplifier when continuous front panel con-
trol of tuner volume is desired. These jacks
may be used to connect to external equip-
ment such as power amplifiers or tape
recorders where control of tuner volume is
necessary. There is no difference in the
signal quality or output levels available at
each pair of output jacks.
STEREOPHONIC FM MULTIPLEX
Connect a shielded cable from the tuner
LEFT channel AUDIO OUTPUT jack to the
control preamplifier LEFT channel tuner or
auxiliary input jack.
Connect a second shielded cable from the
RIGHT channel tuner AUDIO output jack to
the control preamplifier RIGHT channel
tuner or auxiliary input jack. When the MR 71
mode selector is set to MONO or STEREO
AUTO position, a monophonic broadcast will
automatically be present at both left and
right outputs. For a stereo broadcast set the
MODE SELECTOR in the STEREO AUTO
position.
MONOPHONIC FM
The MR 71 can be used strictly for mono-
phonic reception.
Connect a shielded cable from either the
left or right audio output jack to the mono-
phonic control preamplifier auxiliary or tuner
input jack. With the MR 71 MODE SELECTOR
set to MONO, the monophonic FM signal
appears at both the left and right channel
AUDIO OUTPUT jacks.
REMOTE AMPLIFIERS
The pair of audio output jacks not being
used in an installation may be connected to
external or remote amplifiers. An FM pro-

gram can then be fed to speaker systems
apart from the main sound system.
OFF THE AIR RECORDING
Tape recorders or tape decks with record-
playback preamplifiers are normally con-
nected to the Tape Output jacks on the con-
trol preamplifier. Any FM program coming
through the tuner into the preamplifier can
be recorded on tape. You may also connect
the extra pair of tuner audio output jacks
directly to the recorder inputs if desired.
ANTENNA CONNECTIONS
Satisfactory FM multiplex stereo reception
requires 10 times as much signal as FM
monophonic reception. Monophonic installa-
tions that were satisfactory with an indoor
FM antenna may require an outside or direc-
tional FM antenna for satisfactory multiplex
stereo reception. A good directional antenna
with a rotator makes it possible to eliminate
or minimize multipath distortion. The MR 71
multipath indicator shows the correct an-
tenna position for reception with minimum
multipath distortion.
INDOOR FLEXIBLE FM DIPOLE
A convenient flexible indoor FM dipole
(300 ohm) antenna is supplied with the
MR 71 tuner. This antenna is easy to install.
It is suitable for a good FM reception in high
signal areas.
Connect the two leads of the dipole an-
tenna to the two terminals marked 300
OHM on the MR 71 back panel.
The flexibility of the thin flat wire allows the
dipole to be easily located behind the equip-
ment enclosure or any position near the
tuner. Open the dipole into a "T." Extend the
