Advanced Recording Operations

Adjusting Bias, Recording Level

and Recording Equalizer

Calibration

Since there are many different types of cassettes on the market, the tape deck automatically sets the appropriate equalization characteristics and bias current for each tape type (ATS: Automatic Tape Selection).

However, you can get better recording results by adjusting the bias current, recording level and recording equalizer.

1Insert the cassette you want to record on.2Press CALIBRATION.

The display for adjusting the bias, recording level and recording equalizer appears.

3Press rREC.4Press PPAUSE or (to record the test tones. (You can’t hear the test tones.)

After two or three seconds, the meters showing the level of the test tones appear in the display.

Then adjust, in sequence, the bias, recording level and recording equalizer.5Adjust BIAS CALIBRATION so that both meters indicate equal signal levels.

If the upper meter shows a higher level than the lower meter, turn the BIAS CALIBRATION clockwise.

If the lower meter shows a higher level than the upper meter, turn the BIAS CALIBRATION counterclockwise.

7Adjust REC EQUALIZER CALIBRATION so that both meters reach the recommended level.

Turn REC EQUALIZER CALIBRATION clockwise to increase both meters.Turn REC EQUALIZER CALIBRATION counterclockwise to decrease both meters.Recommended levelRepeat steps 5 to 7 if necessary.8Press pto stop recording the test tones. The display returns to normal.9Rewind the tape and start the actual recording.

You can also adjust the bias, recording level and the recording equalizer according to your own taste

For details, see page 17.

Notes

•Because the meters use a wider amplitude during tape calibration, they are more sensitive to slight changes in signal level.

•When you use metal (type IV) tapes, the frequency response to adjustments of the bias current is small. Therefore, adjusting the bias current with the range of this tape deck (a range of about ±20%) may not be effective.
