6 Headphonesjack
This jack is for connection of headphones.
Use headphones with a voice-coil impedance of 4 to 16
ohms.
Note that no sound will be heard from the speakers when
headphones are connected.
7 Speaker selector
This selector is used for respectively turning an or off the
speaker systems connected.
)
Push it inward ( - _ to the " REMOTE ", and push it
again to the "MAIN".
(_ - )
MAIN:
To be used when listening in through the speaker system
connected to the main speaker (MAIN) terminal.
REMOTE:
To be used when listening in through the speaker system
connected to the remote speaker (REMOTE) terminal.
8 Meter range selector
This selector is used for changing over the sensitivity of the
output meter.
)
Push it inward ( - _ to the " x0.1", and push it again
to the " x 1".
x1:
The output of this unit is indicated as it is in the meter.
For example, when the output is 30 W, the pointer indicates
30 W.
x 0.1:
When the output is below 5W an the gradation, the output
must be set at this position.
The output of this unit increased by 10 times is indicated in
the meter.
For reading the actual value, reduce the indication of the
meter to 1/10.
9 High filter switch
If this switch is set to the "ON" position, treble sound which
is higher than 8 kHz is decreased with a sharp curve
characteristic of -6 dB/oct.
This switch is especially useful if there is a great
amount of phono disc "scratch" noise, tape hiss, or if
the tone quality is unsatisfactory because there is much
distortion in the treble sound of the program source.
10 Recording mode selector
This selector is used when recording from one tape deck to
another ("dubbing").
TAPE 1>2:
For recording (dubbing) from tape deck 1 to tape deck
2. SOURCE:
When recording the sound source selected by the input
selector (12), the recording can be made to both tape
deck 1 and tape deck 2 if this switch is set to this
position.
TAPE 2>1:
Tape monitoring can be performed during recording if
this switch is set to either the "TAPE 1>2" (or the
"TAPE 2>1") position.
If, during recording, the tape-minitor selector (11) is
set to the "SOURCE" position, this circuit becomes
independent and has no relationship with the Input
selector 12
selected by the input selector (12) can be heard
without change when dubbing from tape to tape.
11 Tape-monitor selector
For playback from the tape deck connected to the "TAPE 1"
terminals, set this selector to the "TAPE 1" position.
For playback from the tape deck connected to the "TAPE
2" terminals, set it to the "TAPE 2" position.
For reproduction of the sound from the sound source
selected by the input selector 12 , set it to the
"SOURCE" position.
For recording to a trebe-head type tape deck, set it to
(_ -
the "TAPE 1" (or "TAPE 2") position in order to monitor
the recorded sound just after it is recorded.
If it is set to the "SOURCE" position, the sound
immediately before recording can be heard. If, during
recording, this selector is alternately set to the "TAPE 1"
(or "TAPE 2") and "SOURCE" positions, the recordist can
confirm the condition of the recording.
12 Input selector
For selection of the input sound source.
Push it inward (
to the "OFF".
(_ - )
PHONO:
For record player operation.
TUNER:
For reception of broadcasts when connected with a tuner.
Note
These 2 selector are associated with each other, and
therefore, when the switch for the program source to be
played is pushed inward, other switches automatically
project outward to the "OFF".
13 Loudness switch
The loudness control compensates for "thinning out'' of the
sound. Human ears cannot perceive the low-frequency
range at low volumes, but this control compensates for
this, boosting the bass as the volume decreases. Note,
however, that if the volume control is set to a position
higher than the "5" indication, the efficiency becomes less.
For this reason, the program source
