Yamaha CR-840 Owner's Manual page 5

This is used when tuning in FM stations: the indi¬
cator points to dead center when the station is
perfectly in tune.
©DIAL POINTER
Turn the tuning knob to align this pointer to a
desired station.
@HEC OUT SELECTOR
This selects which program source will be recorded,
just as input selector selects which program source
will be heard. With the CR-840, you can listen to
one program source while recording any other
{copy a friend's tape while listening to FM, etc.).
This eliminates "dead" time while you are taping,
permitting you to enjoy the use of your CR-840
while recording.
©IWPUT SELECTOR
This selector switch is used to select the program
source of your choice, whether it be Phono, Tuner,
one of two tape decks, or Aux (for use with 8-track
tape cartridge playback, etc.). The phono switch
position input circuit is designed to operate with
normal moving magnet (MM) type cartridges. Use
of some moving coil (MC) type cartridges is possi¬
ble, but, other low output moving coil cartridges
may require use of a step-up transformer or a head
amplifier.
Use this control to give the volume of sound that
you require. Always start with it turned fully to
the left (counter-clockwise) at the "0" position
before turning it up to the volume level you re¬
quire (clockwise).
If the DX indicator light is on when the IF MODE
switch is in the Auto ( M ) position, it signifies
that the tuner is operating in the DX MODE. When
tuned to a powerful local station, the local mode
takes over.
(AM iodlea^or)
This indicator comes on when receiving an AM
broadcast.
USTEREO (Stereo Indicator)
This indicator comes on automatically when FM
stereo broadcasting is received and goes out auto¬
matically when there is monaural reception.
§BLEND ( Blend Indicator8)
This indicator comes on automatically when the
signal you receive is weak. In weak reception areas,
when a hissing or high pitched noise makes for
poor FM stereo reception, the blend circuit will
cut in to cancel the high-range noises. It operates
when the IF MODE switch is in AUTO ( MJ.
®OTS(OTS Indicator1)
If the OTS indicator light is on when the FM
Muting/OTS switch is in the ON ( J8L) position, it
signifies that the Optimum Tuning System will
correct any slight mis-tuning, to assure optimum
reception of FM stations.
§PHONES A and B Jacke
Two headphone jacks are provided. Plugging into
the jacks does not cut-off power to the speakers,
so it is necessary to use the off position of the
speaker selector switch if you do not want the
speakers to function.
fSPEAKER
With this switch you can select either (A or B) or
both (A + B) of two sets of stereo speaker systems.
§LOCAL (Local Indicator)
It lights up during Local (general) reception. When
the IF Mode Switch is in Local ( -**•), however, it
remains lighted regardless of distant or local re¬
ception.
®LQW and NIOH FILTERS
The low filter gives a sharp 12 dB/octave cut-off
below 25Hz. The high filter has 6 dB/octave cut¬
off slope at frequencies above 8 kHz.
