1. Input Selector Buttons

These 3 buttons permit proper
selection of desired program sources
(phono. tuner, aux). As so called
"see-saw" switch is employed, when
one of these buttons is depressed.
the others protrude automatically.

When 2 or 3 buttons are depressed
compUlsorily at the same time, only

the right-hand one is operative.

2. Volume Control

This knob controls volume. Clock-
wise turn boosts volume, while
counter-clockwise rotation decreases
and finally. cuts off volume.

3. Balance Control

The volume balance between right
and left channels can be adjusted by
this control. Turn it in the clockwise
direction from the center click posi-
tion, and the volume level of the
left channel is reduced. Conversely,
a counter-clockwise turn causes de-
crease of volume at the right channel.
When the volume of both channels is
balanced, monaural playback sound
comes from the center of right and
left speakers. Usually this point is
obtained at the center click point.

4. AC Power Switch
Press alternately for ON or OFF.

5. Pilot Lamp

Press in the AC Power Switch (4)
and this lamp lights up,which shows
that the electric current is on.

6. Mode Selector Button

Use this button to select reproduc-
tion modes such as Stereophonic or
Monaural. When the button is
depressed reproduction is made in
monaural mode. For further details,
refer to Mode Selection.

7. Tape Monitor Button

When this button is depressed,
playback is possible either from
"tape-1" or tape-2". The tape
connector (26) is also functionable
when the switch is set to the "ON"
position (depressed). This is coupled
to the Tape Selector Button, and
for the tape monitoring, it is neces-
sary to select the deck by the Tape

2

Selector.

In case of 3-head tape deck which
has a separate playback head for
playback, simultaneous playback
monitoring is then possible while
recording. In this case this amplifier
receives the playback signals from
the monitor" terminal or tape
connector while feeding the record-
ing signals to REC. OUT and tape
connector.

Caution: if this switch is kept
unpressed in the "protruded" posi-
tion, no playback is possible from
tape recorder.

8. Tape Selector Button

This button is provided to select
two tape decks connected. When the
button is kept unpressed in the
protruded" position (tape-1), repro-
duction of a tape deck is feasible
from TAPE-1 Monitor terminal (22).
When it is depressed (tape-2), repro-
duction from TAPE-2 Monitor termi-
nal (24). This is coupled to the
Tape Minotor Button (7). therefore
when reproduction from tape deck
is required, it is necessary to depress
the Tape Monitor Button.

9. Tape Reprint Buttons

(DUBBING)

Tape dubbing is possible with
these buttons. When the button
"2-1" is depressed, the playback
signals for DECK-2 terminal can be
copied on DECK-1, and vice versa
when the buttons "1-2 is depressed.
While in the dubbing process. it is
possible to monitor with the Tape
Monitor Button. These two switches
are independent push-ON/OFF type,
and it is advisable to depress only
the required button. When both of
them are depressed simultaneously,
the left "2-1" button operates.
Except when reprinting a tape, it is
recommended that these buttons
should be kept unpressed at the
protruded" position.

This reprinting circuit is independ-
ent and reproduction of other
sources as record or tuner is possible
during tape clubbing.

boosts the treble response, while a

obtained in the center of rotation

control of both left and right chan-

ment of different levels between
both channels.

12, 13. Bass Control

A clockwise turn of the control

14. Subsonic Filter

When this button is depressed, a
bass roll-off occurs at 25Hz at the
rate of -6dB/oct. This filter elimi-
nates ultra low frequency noises.
For further details, refer to Sub-
sonic Filter".

16. Loudness Button

When this button is depressed,
compensation of low frequency and
high frequency is realized according
to the reproduction level. This is
useful when listening at low level.
Refer to the "operation of Loud-
ness" for further details.

17. Headphone Jack

Connection of a stereophonic
headphone to this jack allows private
listening. Output signal is always

available. When the headphone is
inserted to this jack, output to the
speaker systems is not available.

18. PHONO Terminal

Output of a magnetic cartridge
(MM, Ml, MC type) can be re-
produced through this terminal.
lnput sensitivity is 2.5mV. Input
impedance is 50k ohms. Except for
very low output MC type cartridge
(output voltage, 0.01mV - 0.1mV),
almost all cartridges can be used.
For such MC type cartridge of very
low output level, it is necessary to
boost voltage up to the specified
level by use of stepcp transformers
or a head-amplifier.
