Use this system when playing back tapes recorded by the Dolby noise-reduction system, such as prerecorded music tapes, etc.

Recording

(con,inued)

When recordings are made at the same recording level and by using ditferent brands of tape, even though the type of tape (regular or "normal" tape, for example) is used, when these recordings are played back the listener may notice that the sound on one tape is lower than the other, or that the high{requency sounds are not as distinct on one tape or the

other, etc. The reason that such differences may be noticed is because there are differences of the sensitivity (the magnitude of the recording level) and of the frequency response (particularly in the treble range) between cassette tapes of the various manufacturers of tape.
Although, for recordings and playback in which a noise-reduction

system is used, it is the principle for such recordings that the recording and playback processes be at the same recording level, if, as a result of the reason described above, there is a difference of the recording level or of the frequency response, there will result a difference in the processes for recording and for playback, and correct recordings and playback cannot be accomplished. ln order to overcome this problem, this unit includes recordingcalibration controls (for compensation of differences of the recording level) and a bias-adjustment control (for compensation ot the frequency response) so that the recording level can be set to the most appropriate level during recording.

I

Compensations can be made, as shown in the figure below, by using the recording-calibration controls and the bias-adiustment control.
