MI Switches & Controls

1. Input Selector Switch

This switch permits proper selection of desired program
sources. You may set either of the positions provided [AM,
FM, phono subsonic, phono, aux].

2. FM Muting Off Switch

Annoying interstation noise which is possible wnen tuning is
shifted out of the exact tuning point can be eliminated by this
switch in the case of FM reception. Keep this switch unpressed
to remove interstation noises or other impracticably weak
signals. Such FM signals as can be received in the "muting-on
position can be practised for stereo FM reception. It is recom-
mended to set this switch always at the "protruded" position
except when weak signals are received.

3. Mono Switch

This allows to select sound reproduction modes such as
Stereophonic and Monaural, For further details refer to the
Mode Selection".

4. Tape Monitor Switch
When this switch is pressed in. tape playback is possible from
the Monitor terminals. in the case of 3-head tapevrecorder
which has a playback head simultaneous playback monitoring is
possible while recording. in this case this tuner-amplifier re-
ceives playback signals from the Monitor Terminals while
feeding recording signals to the Rec. Out Terminals.

5. Tape Selector Switch
This switch allows to select tape playback terminals. When
this is kept unpressed, tape playback is feasible from the
TAPE-1 Monitor Terminal, while when pressed in, the Tape-2
Monitor Terminal is put into function.

6. Tape Dubbing Switch

The Tape dubbing switch is provided with 3 positions; in the
center "source" position such program source as is selected by
the Input Selector Switch is available for playback.

When the switch is set to the "1-2 position the output of
tape recorder-l is fed to the input of tape recorder-2 for reprint-
ing, while the "2-1" position offers tape dubbing from
TAPE-2" to TAPE-1", As this Dubbing Switch is inde-
pendent of the signal path, you can enioy playback of other
program sources even during tape dubbing.

7. Low Cut Filter
When this switch is pressed in, the amount of low frequency
range you hear is reduced at the rate of -6dB/oct. below
70 Hz. See the details in the "Operation of Low Cut Filter".

8. High Cut Filter
With this filter switch you can cut off the high frequency
range above 7 KHz at the rate of -6dB/oct. See the details in
the Operation of High Cut Filter",

9. Bass Control
This is a level control of bass range. A clockwise turn of the
control boosts the bass response, and a counter-clockwise turn
decreases it. This yields a flat frequency response when set at
the rotation angle.

10. Treble Control

A clockwise turn of this knob boosts the treble response.
while counter-clockwise turn decreases the treble level. This
control is of the same construction as that of the Bass Tone
Control.

11. Loudness Switch

When pressed in this switch, loudness control starts to func-
tion. This may be useful when you listen to music at low
volume level. Refer to the details in the "Operation of Loud-

ness .

12. Volume Control

A clockwise turn of this control increases volume, while a
counter-clockwise turn decreases and finally cuts out volume.
This is of dual concentric structure allowing separate control on
the right and left channels. The front part is for the left
channel, while the rear one is for the right. When the sound
volume is balanced, sound is heard as if reproduced at the center
of left and right speakers, with the Mono Switch set to the
depressed" position. Normally this tuner-amplifier is delivered
from the factory well balanced in volume showing a straight
concave line on the knob. See the further details in the
"Volume Control".

13. Speaker Selector Switch

This tuner-amplifier offers convenience to use 2 pairs of
loudspeakers. You can choose independent or simultaneous
driving of l or 2 systems. When the knob "A" is depressed,
"A" speaker terminal starts to function. and likewise the A"
and "B" are pressed in, both A" and "B" speaker terminals
operate.

Note that the impedance of each speaker system should
exceed 8 ohms when 2 pains of speakers are simultaneously
driven.

14. Tuning Direction Indicator

In the case of FM reception, this indicator shows the direc-
tion of tuning, When a broadcasting station is coming near. the
indicator begins flashing. Turn the Tuning Knob slowly to the
direction shown by the indicator, and the flashing ceases at a
point where the precise tuning point is obtained. At this time,
the Indicator shows the signal strength of the station just tuned
in. When 3 or more indicators light up, stable reception in
stereo mode is feasible.

Note that the indicator acts only as a signal strength indi-
cator for AM reception.
