HOW TO USE REC MUTE
When REC MUTE Switch is depressed during recording, the
recording amp circuit will be brought into a NO-SIGNAL
mode, causing the Timing Lamp to flash at intervals of
approximately one second. No recording will be made on
the tape during this period. Further, during REC MUTE,
source monitoring can be effected (though it will not be
recorded on the tape), by changing over the Monitor Switch
to SOURCE.
When dubbing from disk records, or editing the tape while
dubbing, a NO-SIGNAL portion of an arbitrary length can
be inserted between the music by making use of the Timing
Lamp that flashes at about one-second intervals.
With respect to Operations 13, 14 and 15 of “STEREO
RECORDING 1”, refer to the following as a typical exam-
ple of clever utilization of REC MUTE.
Carry out Operations | through 13.
14, When reaching a point where a NO-SIGNAL recording
portion is to be inserted, depress REC MUTE Switch.
(Indicated in drawing below.)
* This will cause the Timing Lamp to flash at about one-
second intervals.
15. After determining the time length to be placed
between the music, count the times for which the
Timing Lamp has flashed and push down and lock the
Pause Lever in the direction of the arrow to effect the
PAUSE mode.
* This will cause the Timing Lamp to go out and the REC
MUTE mode to be released,
Operations 16 and 17 are to be carried out similarly to
those previously described.

HOW TO SET RECORDING INPUT LEVEL
Since sensitivity will vary according to the tape used, the
best way to set the recording input level will be to adjust
the Input Controls (with the unit in the RECORDING
mode and the Monitor Switch positioned to TAPE) in a
manner to bring it close to “‘OVU”’ when the swing of the
VU Meter’s indicator is maximum. Even if the left and right
Input Controls are positioned somewhat differently, the
level indicated on the VU meter should be considered as the
standard for all adjustments and therefore, level adjust-
ments should be effected centering on the VU Meters. This
will ensure the best recording level.
Because this machine is equipped with GX Heads, not only
has loss been minimized during recording and playback but
recording without any distortion is possible even when the
level exceeds ‘““OVU’’ when using the wide dynamic-range,
high-performance tape.
Further, at recording, the level can be raised to the highest
possible range without distortion by simultaneous monitor-
ing. By raising the level, the dynamic range becomes that
much wider, enabling recording with excellent S/N ratio.
* Depending on the recording input, the VU Meter will not
indicate distortion that has generated in the recordings on the
tape. Even in such cases, the presence of any distortion can be
checked through simultaneous monitoring.
1. Level is too low.
S/N ratio deteriorates.
2. Level is just right.
Excellent recording
3. Level is too high.
Distortion generates.
HOW TO USE MEMORY MARKER
In the playback of sources such as music, if the number is
suddenly started in a large volume, or if it suddenly ends in
an abrupt manner, the effect would be quite unnatural. To
avoid such phenomena from occurring, such recording
techniques are employed as those known as FADE-IN,
which is the technique in which recording is started in a
small volume and then is gradually raised until the optimum
volume is reached, or FADE-OUT, in which, the sound at
the end of the number is graduaily diminished from an
optimum volume.
To effect FADE-IN,. the Recording Input Control is
gradually tuned up until the volume reaches an optimum
recording level. Thus, it is necessary to have the position of
the optimum recording level marked in advance. Mean-
while, in the case of FADE-OUT, the Input Control is
gradually tuned down from the position of the optimum
recording level. In this case too, it is necessary to have the
position of the optimum recording level marked. Since the
Memory Marker is not interlocked with the movement of
the Input Control, it is capable of indicating the position of
the optimum recording level at all times. Notably for
FADE-IN, in which the Input Control is tuned from
minimum up to the optimum-level position, it is important
that the optimum position of the Input Control be
indicated in advance.
The Memory Marker, by being set to the optimum volume
position, thus offers convenience in FADE-IN and FADE-
OUT operations.
SIMULTANEOUS MONITORING
This is the method by which the condition of recording
that is taking place on the tape is confirmed during
recording operations.
By making use of this method, it is possible to confirm
whether an important program is being positively recorded
or not. or to check for any distortion due to overlevel
recordings.
MEMORY MARKER
With the machine set in the RECORDING mode, and by
positioning the Monitor Switch to:
a) SOURCE, the original recording input signals can be
monitored. (The recording input signals flow in the
manner of @ and @ shown invthe drawing.)
b) TAPE, the newly recorded signals on the tape can be
monitored. (The signals will flow in the manner
of @ and @ shown in the drawing.)
