Select the audio mode.
Select either two-channel mode (2CHANNEL) or four-channel mode
(4CHANNEL) with the REC MODE menu item (see page 69). The
corresponding indicator lights in the REC MODE display.
Cautions
• In the DVCAM format, there are two audio recording modes, with either
two channels at 48 kHz or four channels at 32 kHz. It is not possible to
select other modes (for example with four channels at 48 kHz).
• During audio editing, if a signal used in assemble or insert editing is in a
different mode from the base tape, the signals will be discontinuous at the
edit points, and correct editing will not be obtained. For this reason, audio
editing between different modes is inhibited on this unit.
For smooth editing operations, check the audio recording mode of the
base tape beforehand.
• Once you have started recording, you cannot change the audio mode
selection.
• If on a tape there is a point where the audio mode is switched, it is not
possible to carry out insert editing over a section including that point.
7
Use the AUDIO INPUT LEVEL control knobs to adjust audio input levels.
Watching the audio level meter, adjust the level so that the meter does not
indicate higher values than 0 dB when the audio signal is at its maximum.
When the level exceeds 0 dB, the OVER indicator lights.
The factory-preset audio recording level is
−20 dB (DSR-1800A) or −18 dB
(DSR-1800AP). This setting can be changed using the LEVEL SELECT
menu item (see page 71).
