Bias adjustment
The BIAS ADJUST control is for fine adjustment of the
recording bias. Normally, it is not necessary to adjust this
control since the recording bias can be automatically
adjusted by the built-in Auto Tape Selector and the
AUTO
TAPE TUNING button for different tape types.
However, if you feel that your recording needs further bias
adjustment (to compensate for absent or distorted high
frequencies), adjust this control to your liking.
When high frequencies are
distorted, increase the
recording bias by turning
the BIAS ADJUST control
clockwise. When high frequencies are
absent, decrease the recording
bias by turning the BIAS
ADJUST control
counterclockwise.
Setting the recording level (in step 5)
Play the loudest passage of the source to be recorded
and watch the meter readings. Adjust the
REC LEVEL
control so that the highest peak may not exceed the
optimum levels of each tape type. Normally, it is best to
adjust the
BALANCE control such that the LEFT and
RIGHT meter readings are even.
