RECORDING BIAS ADJUSTMENT
For best recording results, monitoring during the recording
process and comparing various recordings using your own
judgement are essential.
The DRM-800A is equipped with a bias adjustment
control to assist you in setting the proper bias for different
types and brands of recording tape. At the center-stop
position, the deck is set for a reference bias level' for
NORMAL,
CrGz
and METAL tapes. If the resulting redording
in this position has too much or too little high frequency
content, varying the bias adjustment control can be useful
to achieve better results.
If the high frequencies (treble sounds) are to be boosted,
turn the bias control counterclockwise to decreases bias
current. If distortion is of more concern than high frequency
response, turn the control clockwise to increase bias current,
By the use of this control, you can record tapes with res-
ponse that matches your personnal listening tastes.

I
This Stereo Cassette Deck contains an Auto Tape Select feature which automatically selects the optimum bias and
equalization for the tape in use. This is accomplished by detection of tape type detection holes in the cassette housing.
The Tape type (TYPE-
I,
TYPE-
II
or TYPE-
N)
is indicated by the TAPE SELECT indicator.
• If a tape without tape type detection holes is used,
the TAPE SELECT indicator will not indicate the
correct tape type and the deck will automatically
adjust itself for normal tapes.
