4.9. Playback Head and Record Head Height Adjustment
and Azimuth Alignment

(1) Playback Head Height Adjustment and Azimuth
Alignment

Refer to Fig. 4.22.

(a) Set the Monitor switch to Tape, then connect a
VTVM to the Line Output Jacks.

(b) Set the Manual Set button, then set the Eq. switch

to 70 us and Noise Reduction switch to Out.

Load a 1 kHz Track Alignment Tape (DA09007A),

then set the N-lOOOZXL in Play mode.

Turn the PH Height Gear until the outputs of both

channels become minimum.

Load a 15 kHz Azimuth Tape (DA09004A), then set

the N-1000ZXL in Play mode.

Turn the PH Azimuth Alignment Screw until the

outputs of both channels become maximum.

Repeat above steps ((2) through (f) one or two times

to obtain optimum performance.

(2) Record Head Height Adjustment and Azimuth Align-
ment

Refer to Figs. 4.22 ~ 4.26.

(a) Set the Nv10002XL in Stop mode.

Turn the Azimuth Motor in the Azimuth Alignment

Motor Ass'y by hand so that the Alignment Indicator

corresponds to the pointer of the Azimuth Alignment

Motor Assy as shown in Fig. 4.23. Remove the

Azimuth Alignment Wire by pulling out from the

Azimuth Alignment Motor Ass'y. In this case, do not

move the Slide Lever of the Azimuth Alignment Wire.

Set the Monitor switch to Tape, then connect a

VTVM to the Line Output Jacks.

Set the Eq. switch to 70 us and Noise Reduction

switch to Cut.

Load a Reference SX Tape (DA09025A). Then set

the N-1000ZXL in Record and Pause mode.

With pressing the Auto Calibration button Run".

press the Play button to set the N-lOOOZXL in Auto

Calibration mode.
