Tuning Meters; Tuning; Fm Antenna Orientation; Mono In {L, R)Switch - Marantz 2210 Instructions Manual

TUNING knob until the desired station
is tuned. Adjust the volume control
for comfortable listening volume.
The tuner section of the Model 2270 is equipped
with electronically triggered circuits which auto­
matically mute interstation noise and automati­
cally switch to the proper mode of operation for
stereo and monophonic FM broadcasts. In addition,
the STE REO indicator light automatically indi­
cates a stereo broadcast.
TUNING METERS
The Model 2270 is equipped with two meters, a
SIGNAL STREI\IGTH MU LTIPATH meter and a
TUNING meter.
1. The SIGNAL STRENGTH/MU LTIPATH
Meter is dual purpose:
a. In normal operation, it indicates the sig­
nal strength of the AM or FM signal to
which your receiver is tuned.
b. If you push in the MULTIPATH push­
switch -- and only so long as you hold it
in -- this meter will indicate multipath,
to enable you to point your FM antenna
in the best direction to optimize FM re­
ception.
2. The TUNING meter operates on FM only
and indicates correct station tuning.
TUNING
AM: For optimum AM reception, tune to the
desired stat ion. Then rotate the tuning knob
slightly back and forth until the maximum reading
is obtained on the SIGNAL STRENGTH Meter.
The TUNING Meter is not used for AM.
FM: Switch the selector to FM and tune to the
desired station. Then slowly rotate the tuning knob
slightly back and forth until maximum reading is
obtained on the SIGNAL STRENGTH Meter, and
the TU N ING Meter points to the center scale
position. Your Receiver is now properly tuned.
FM ANTENNA ORIENTATION
With a rotatable FM antenna, you may further opti­
mize FM reception by pointing the antenna to the
proper direction for minimum multipath.
First tune to the desired station as above. Then ho­
ld in the MULTIPATH pushswitch while you rotate
the FM antenna. Stop the antenna at that position
for which minimum deflection is indicated on the
MULTIPATH meter. Then release the MULTIPATH
pushswitch to restore the meter to its normal SIG­
NAL STRENGTH function.
MONO IN {L, R)SWITCH
Depressing both MONO IN (L, R) pushswitches
will convert all input signals to the monophonic
mode excluding signals at the rear panel record and
front panel TAPE dubbing jacks.
While playing a single channel source such as TV
or AM, depress both MONO IN (L, R) push­
switches to feed the signal through both channels.
When playing a monophonic phonograph record,
usethese pushswitches to suppress rumble, common
mode noise and pinch - effect distortion.
TAPE/SOURCE MONITOR SWITCH
When this pushswitch is out (SOURCE) the program
being recorded and heard is determined by the set­
ting of the selector switch. With the MONITOR
pushswitch in (TAPE), the amplifier input connec­
tions are switched to the output of the tape recor­
der without affecting the signal presented to the
tape recorder without affecting the signal presented
to the tape recorder's input. Thus you may listen to
the source signal before and after it is recorded (on
a 3-head tape recorder).
A tape recorder to be monitored is selected by this
pushswitch. When this pushswitch is "out (2)/' the
tape recorder connected to the PLAY 2 jacks on
the rear panel is monitored. With the pushswitch ,.
in (1)."the tape recorder connected to the PLAY 1
jacks is selected. If a tape recorder is connected to
the dubbing
11\1
jacks on the front panel, the tape
recorder is always selected regardless of any posi­
tion of the pushswitch.
LOUDNESS SWITCH
For more pleasing tonal balance at low level
listening, the bass and treble should be boosted.
With the LOUDNESS switch depressed, the bass
and treble are automatically boosted at low listen­
ing levels to maintain this tonal balance .
Hi-BLEND SWITCH
With the pushswitch "in," stereo separation is sligh­
tly reduced for high frequencies. For weak FM sig­
nals with excessive noise and/or interference, this
offers moderate separation with moderate suppres­
sion of out-of-phase noise and distortion compo­
nents. Unlike most FM noise filters, this does not
sacrifice full frequency response.
Hi-BLEND will also reduce phonograph record pin­
ch-effect distortion and vertical noise components,
but will not materially affect tape "hiss."
For normal listening, leave this pushswitch "out."
