FUNCTIONS
EM MUTING/MODE SWITCH
This switch is used to eliminate unpleasant intor
station noise which occurs during sclection of FM
broedeasting stations. The muting circuit sup-
prestes this noise, and makes FM selection easier.
© In the areas where the distance from the HM
station is comparatively small, set. this switch to
ON.
© In the areas where the field strength is very
weak, set this switch to OFF during selection.
A distant, weak station can be received even
'though the noise becomes greater.
© If recording of a stereo FM program onto mo-
aural tape is desired, set this switch to MONO.

FM/AM IF BAND SWITCH
'The FM/AM IF band switch is used to switeh the
intermediate frequency signal pass band width of
FM and AM between NARROW (narrow band) and
WIDE (wide band). If there is a station close to the
desired station, set this switch to NARROW; the
selectivity will become sharp, and interference will
be avoided. On the other hand, if there is not a
station close nearby, act this switch to WIDE; the
sound quality of the received program will be
improved, Further, the behavior of the signal meter
pointer varies according to the switch position;
WIDE or NARROW. When set to WIDE, the width
of the tuning point is comparatively large, and the
pointer moves slowly. At NARROW position, the
pointer moves sharply as the width of the tuning,
point is very narrow.
OUTPUT LEVEL KNOB
'The Tuner is provided with variable output jacks
whose output level ean be varied by adjusting the
output level knob on the front panel, and also
fixed output jacks whose output level is fixed,
Using the VARIABLE jacks
'The output level can be adjusted using the output
level knob, thereby making it possible to bring the
output levels of the Tuner and of the other com:
ponents connected to the stereo amplifier in line
with each other.
