MZ-NH1

• Note For Printed Wiring Boards and Schematic Diagrams

• Main board is multi-layer printed board.

However, the patterns of intermediate-layer have not been in-

cluded in this diagrams.

• Lead Layouts

Note on Schematic Diagram:

• All capacitors are in µF unless otherwise noted. (p: pF)

50 WV or less are not indicated except for electrolytics

and tantalums.

• All resistors are in Ω and

W or less unless otherwise

specified.

• f : internal component.

• C : panel designation.

• A : B+ Line.

• Total current is measured with MD installed.

• Power voltage is dc 6 V and fed with regulated dc power

supply from CL451 (DC IN 6V) and CL460 (VBUS GND).

• Voltages and waveforms are dc with respect to ground

under no-signal conditions.

no mark : PLAYBACK

(): PLAYBACK (servo on)

[]: PLAYBACK (servo stop)

∗ : Impossible to measure

• Voltages are taken with a VOM (Input impedance 10 MΩ).

Voltage variations may be noted due to normal produc-

tion tolerances.

• Waveforms are taken with a oscilloscope.

Voltage variations may be noted due to normal produc-

tion tolerances.

• Circled numbers refer to waveforms.

• Signal path.

E : PLAYBACK

j : REC

J : OPTICAL IN

F : LINE IN

d : USB input from PC

G : USB output to PC

N : MIC IN

• Abbreviation

E18 : 100V - 240V AC area in E model

JE : Tourist model

Note on Printed Wiring Board:

• X : parts extracted from the component side.

• Y : parts extracted from the conductor side.

• f : internal component.

• : Pattern from the side which enables seeing.

(The other layers' patterns are not indicated.)

Caution:

Pattern face side: Parts on the pattern face side seen from

(Conductor Side) the pattern face are indicated.

Parts face side: Parts on the parts face side seen from

(Component Side) the parts face are indicated.

Note: The components identified by mark 0 or dotted line

with mark 0 are critical for safety.
