• Power voltage is dc 14.4V and fed with regulated dc power

supply from CD changer controller.

• Voltages and waveforms are dc with respect to ground

under no-signal conditions.
no mark : CD PLAY

• Voltages are taken with a VOM (Input impedance 10 M

Ω

).

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.
