Adjusting Bias and Recording
Level Calibration
Since theTe*aTe many different t>'pes of c«\ssettes on the
market, the tape deck automatically sets the
appropriate equalization characteristics arvd bias
current for each tape type (ATS; Automatic Tape
Selection).
However^you can get better recording results b>'
adjusting^ bias current and recording le\ el
calibration.

V can also adjust the bias current and recording
level calibration according to your own taste

Notes
• Because the meters use a wider amplitude during tape
calibration, they are more sen.sitive to slight changes in
signal level.
• When you use metal (tyj,M- IV) tapes, the I'ret^uencs’
respitnse to adjustments of the bias current is small.
Xheretore, adjusting the bias current with the range of this
tap*' deck (a range of abiUtl ±20".) may n«)t Iv effective.
