Tips on recording level adjustment
Setting the recording level too low will produce a hissing
sound, while setting it too high will produce distortion.
Generally, the optimum recording level for high and low
frequencies is lower than that for middle frequencies.
Therefore, when recording program sources with many high
and low frequencies, you should set the level to a relatively
low position. For even better results, check the recording
results with your own ear.
Recording FM Broadcasts With the Dolby NR
System
When recording FM broadcasts with the DOLBY NR system,
set the MPX FILTER button to ON (the FILTER indicator
appears).
The MPX filter eliminates remnants of the 19-kHz stereo
carrier and 38-kHz subcarrier signals which may impair the
operation of the DOLBY NR system. Be sure that the Dolby
NR switch is turned on since the MPX filter will not function
otherwise. During recording with the Dolby NR system, use
this switch only if the tuner is not equipped with its own MPX
filter or the equipped filter does not function effectively.
As this unit has three separate heads for recording, playback
and erasure, you can check the quality of a recorded sound
by comparing it with the input source signal.
To listen to the input source signal, press the MONITOR
button to turn on the SOURCE indicator.
To listen to the sound recorded on the tape, press the
MONITOR button to turn on the TAPE indicator.
Comparing the recorded sound with the sound source
While recording, use this monitoring function to check that
there is no distortion due to excessive level settings or sound
degradation due to head contamination.
