•Setting the bias current higher or lower
than the proper setting for a certain tape
changes the frequency response as shown
in the Chart in Fig. B . You can thus
change the bias to tailor the response to
your liking, for example by slightly
emphasizing the upper or lower end.
•The frequency response of metal tape is
much less affected by changes in the bias
current than other tape types, and in some
cases is uneffected. The adjustment range
of this deck (about
± 20 %) may therefore
not be wide enough to allow adjustment
for all tapes.
Recording level calibration
Even when the recording level is adjusted
correctly, a tape with low sensitivity will
result in a low playback level. The REC
LEVEL calibration control allows you to
compensate for sensitivity differences
among tapes to equalize both recording and
playback levels. This is especially important
when using the Dolby NR system, since the
system is most effective when recording
and playback levels are the same.
