Select the audio mode.
Select either two-channel mode (2 CHANNEL) or four-channel mode (4
CHANNEL) with the REC MODE menu item (see page 66). The
corresponding indicator lights in the REC MODE display.
Cautions
• When recording in DVCAM format or this unit’s DV (SP) format, two
audio recording modes, with either two channels at 48 kHz or four
channels at 32 kHz, can be used. It is not possible to select any other mode
(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, the
menu settings on this unit are arranged to inhibit audio editing between
different modes.
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 or
recording format.
• 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.
• When, in 4-channel mode, analog audio is selected for all four channels
(channels 1/2 and 3/4), the same analog audio signals are recorded on
channels 1 and 3 and on channels 2 and 4, respectively.

When manually adjusting audio input levels
With the VAR switch on the front panel set to REC, use the REC/PB
LEVEL control knob for each channel to adjust the audio input level.
Watching the audio level meter in E-E mode, 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.
When recording at reference level
When the VAR switch on the front panel is set to PRESET, recording is
carried out at the preset reference level.
Reference level setting
The factory-preset reference level for analog audio input is
−20 dB (DSR-
1500A) or
−18 dB (DSR-1500AP). This setting can be changed using the
LEVEL SELECT menu item (see page 67).
For recording in DV (SP) format, the reference level is fixed at
−12 dB.
Recording Procedure
This section describes the procedure to perform recording on this unit, showing
an example session in which playback signals coming from a player VCR will
be recorded on the tape loaded in the unit.
