Recording from Various Sound Sources

Notes

• When you are going to record something that you may not have an

opportunity to record again, test the unit first before you actually start
recording.

• When recording with an external microphone, the VOR system may not

work properly because of the difference in sensitivity.

Recording with an External Microphone

Connect a microphone firmly to the MIC jack.

M-673V : use the supplied microphone.
Other models : use a microphone of low impedance (less than 3
k ). When using a plug-in-power system microphone, the
power to the microphone is supplied from this unit.

Connect another equipment firmly to the MIC jack using the
connecting cord (not supplied).
Set this unit to the recording mode and another equipment to
the playback mode.

Notes on VOR (Voice Operated Recording)

• The VOR system is affected by the environmental recording conditions.

When you use the system in a noisy place, the unit will stay in the
recording mode. If the sound is too soft, on the contrary, the unit will
not start recording. If you cannot get the results you want, set it to OFF.

• The VOR system may not record the beginning of the sound you want

to record because it starts recording only after it catches the sound. For
an important recording, set it to OFF.
