5. PCB PARTS LIST

NOTES:•Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List.

The mark found on some component parts indicates the importance of the safety factor of the part.

•

Therefore, when replacing, be sure to use parts of identical designation.
When ordering resistors, first convert resistance values into code form as shown in the following examples.

•

Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%,
and K=10%).

560 Ω→56 × 10

47k Ω→47 × 103→ 473 ........................................................RD1/4PU 4 7 3 J

0.5 Ω→R50 .....................................................................................RN2H

1 Ω→1R0 .....................................................................................RS1P

Ex.2 When there are 3 effective digits (such as in high precision metal film resistors).

5.62k Ω→ 562 × 10

1

→ 561 ........................................................RD1/4PU 5 6 1 J

R 5 0

6. ADJUSTMENT

For adjustment, use the stereo power amplifier (M-IS21).

6.1 DECK SECTION

6.1.1 Adjustment Condition

(1) The ground at the time of adjustment shall be W166.

(Refer to Fig. 6–3).
(2) Clean the heads and demagnetize them using a head eraser.
(3) Set the measurement level to 0 dBV = 1 Vrms.
(4) Use the specified tape for adjustment. Use the labeled (A) side

of the test tape.

NCT–111 : For Tape Speed adjustment

STD-331E : For Playback adjustment

STD–632 : Normal blank tape

* As the reference recording level is 250 nwb/m for STD–

331E, the recording level will be higher by 4 dB for STD–

331B (160nwb/m). When adjusting, pay carefull attention
to the type of tape used.

(5) Provide yourself with the following measuring devides:

÷ AC millivoltmeter
÷ Low-frequency oscillator
÷ Attenuator
÷ Oscilloscope

(6) Adjust both right and left channels unless otherwise specified.
(7) Turn the DOLBY NR switch off unless otherwize specified.
(8) Warm up the unit for several minutes before adjustment. In

particular, be sure to warm up the unit in the REC/PLAY mode

for 3 to 5 minutes before starting recording/playback frequency

characteristics adjustment.
(9) Always follow the indicated adjustment order.

Otherwise, a complete adjustment may not be achieved.

Notes)

• PCMD is an MSB first. two's complement output.

• GTOP is used to monitor the frame sync protection status. (High:sync protection window released)

• XUGF is the negative pulse for the frame sync derived from the EFM signal. It is the signal before sync protection.

• XPLCK is the inverse of the EFM PLL clock. The PLL is designed so that the falling edge of XPLCK and the EFM signal transition point coincide.

• GFS goes high when the frame sync and the insertion protection timing match.

• RFCK is derived with the crystal accuracy. This signal has a cycle of 136µs.

• C2PO represents the data error status.

• XRAOF is generated when the 16K RAM exceeds the ±4F jitter margin.
