The Peak Level Indicator has been provided to compensate
for such a short-coming. It is useful especially for cassette
tape recording in that the cassette tape has a narrower
dynamic range than an open-reel tape and is, therefore, sub 
ject to more sound distortion when recorded with an extra
high input level setting (saturation).

How to Use BIAS and EQ
(Bias and Equalization Selector Switches)
When in Record, the BIAS and EQ selector switches select
the appropriate recording bias and equalization according to
the type of tape used. The EQ switch is set to the proper
position in Playback according to type of the tape used, as
indicated below:
Effect of PAUSE Button
Use the PAUSE Button for better cueing when recording.
First, install a cassette tape properly and then depress the
PAUSE Button (9). Now. depressing the REC (Record
Button), press ► (Play Button). This makes your 450 set
ready for recording. Adjust recording level properly and wait
for a chance to start recording.
Set as above, your 450 starts recording immediately when
the PAUSE Button is pressed again With the PAUSE Button
pressed again as mentioned above, the tape starts moving
forward to record. To temporarily halt the travel of the tape
during recording, press the PAUSE Button once again, not
the Stop Button.
To Monitor Recording
Connect an 8-ohm type stereo headphone to PHONES (Head 
phone Jack) when the tape deck is in Record position, and
you can monitor through the headphone the input signals
being recorded. The headphone monitoring combined with
the check by the VU Meter provides an excellent recording
level check.
The Peak Level Indicator of the 450 has been preset to
indicate at the level from where recording generally begins
to distort. It may also illuminate during playback.
When the input signal level is too high, this Peak Level
Indicator lamp illuminates to indicate that the input signal is
being recorded with distortion. When it illuminates, lower
the input level until the lamp light stays out. With the input
level adjusted properly, you will have the input signa! record 
ed clearly and without distortion.

Tape Counter
Before beginning to record or playback from the beginning
of the tape, reset the Counter to "000" by pressing
the Reset Button. The counter adds when the tape travels
in the forward detection. Log the numbers indicated on
the Counter for each particular recorded selection, so that
those selections may be easily relocated later.
When the level variation of an input signal is gradual, the VU
meter can deflect quite faithfully in proportion to the input
signal strength. When the variation is drastic, however, the
meter fails to follow in time the changing levels of the input
signal, thus giving the level indication that is often lower by
a few dB than the actual input level. For example, the meter
may indicate 0 dB for an actual input signal of +6 dB.
How to Use the Peak Level Indicator
Compared with the peak level meter of a professional model,
the transient characteristics of VU Meters used in popular-use
tape deck, are generally not so good. (The transient characte 
ristic referred to herein represents how faithfully the VU
meter can react to rapid changes in the input signals.)

To Set Recording Level
The VU Meter @ indicates output level in Playback and
input level in Record. For the recording level adjustment,
first depress the PAUSE Button and then, depressing the
REC (Record Button), press ► (Play Button) simultaneously.
The VU Meter is now ready to indicate the input level, that
is. the recording level. Set as above, your 450 permits you
to monitor the input signals through the headphone.
While watching the VU Meter, adjust the recording level with
MIC (Microphone Input Volume Control) @ for the micro 
phone or DIN input or with LINE (Line Input Volume
Control) ® for other inputs. Set the recording level to a
level where the VU Meter ’ s pointer will not deflect too far to
the maximum even with the momentary maximum input.
Recording that gives the best S/N ratio can be obtained when
the recording level is set to such a level that the VU Meter ’ s
pointer will be deflecting as fully as possible within the range
marked by “ 0 ” for Dolby recording or ordinary recording.
If the recording level is so high that the VU Meter ’ s pointer
deflects too far to the maximum, the recording may
have distortion. Such a distorted recording is unpleasant
to hear when reproduced.
