1 AUDIO OUTPUT CH-1 to CH-4 jacks (phono
jack)
Outputs audio signals (CH-1 to CH-4).
2 AUDIO INPUT CH-1 to CH-4 connectors (XLR
3-pin, female)
Inputs audio signals (CH-1 to CH-4).
Note
The unit employs electronically balanced AUDIO
INPUT connectors. To input unbalanced audio signals
(a phono jack of a consumer VCR, etc.), use a
conversion cable as shown below. (This conversion
cable shorts the COLD and the common terminal
(GND)).

3 Audio input level (—60/—20/+4) control selectors
When the INPUT SELECT selector is set to other than
DV, select an audio input signal level (
— 60/ — 20/+4) for
the CAMERA connector or AUDIO INPUT
connectors.
Notes
¥ If this switch setting is not appropriate, clipping
distortion or noise may occur even if the AUDIO
SELECT switch has been set to AUTO.
¥ The unit is not compatible with a camera that outputs
+4 dB. If you set the audio input selectors to CAM,
select
— 60 dB or — 20 dB depending on the output
level of the camera.
¥ If you can select the output level ( — 60 dB or — 20 dB)
on the camera, select — 20 dB on the camera and the
unit. When the unit and the camera are connected
with a long camera cable, noise may be minimized.

+48V ON: Supplies power to the 48 V microphone.
Notes
¥ If you have se48V ON, do not insert a metal
object into the AUDIO INPUT connectors. It may
cause electric shock.
¥ If you have se48V ON, use a microphone that
is compatible with 48 V. Using a microphone that is
incompatible may damage the microphone, generate
smoke or cause a fire.

Left Panel
1 DVCAM/DV select switch
Switches the recording mode between DVCAM and
DV (SP mode only). When you play back a tape, the
DVCAM/DV setting will be automatically switched;
you do not need to use this switch.
Notes
¥ The unit is not compatible with playing or recording
in consumer DV format (LP mode).
¥ If you switch the DVCAM/DV select switch setting
while recording, the unit automatically pauses the
recording and then resumes recording several seconds
later. Nothing is recorded during that interval. You
cannot change the mode smoothly while recording.
¥ It is recommended that you record in the DVCAM
format. There are some limitations with respect to
DV recording depending on machine specifications
and the consumer DV format as follows:
— The head system is optimized for DVCAM
recording. A DV recording overwrites the last track
just before the beginning of the recording. As a
result, at the border of these two recorded portions,
picture and sound may be distorted.
— The sound will be recorded unsynchronized.
(unlock mode)
— The time code is fixed to the drop frame mode.
(only for DSR-50)
— You cannot change the TC PRESET, UB PRESET,
TC FORMAT, TC RUN, TC/UB IN, TC MAKE,
UB TIME settings on the TC/UB SET menu. The
setting and status set at the time of the DVCAM
recording will be canceled.
— The time code automatically progresses so that the
recorded tracks are continued.
— If you start recording from a blank portion, the time
code starts from 00:00:00:00.
— The user bits are not recorded. When you play back
the tape, the user bits display will be
— — — — — — — — .
— Even if you input an external time code into the TC
IN connector, the time code used will be the one
provided by the internal time code generator.
¥ If you dub a consumer DV tape from the DV IN/OUT
connector, keep the following in mind:
— Set the DVCAM/DV select switch to DV. If the
DVCAM/DV select switch has been set to
DVCAM, a tape with an invalid format (the
recording speed: DVCAM, sound: unsynchronized,
unlock mode) will be made. (The unit cannot
convert unlock mode sound to lock mode sound.)
— When you edit a tape with an invalid format in the
DSR-70/70P, DSR-80/80P, DSR-85/85P, DSR-
2000/2000P, etc., there may be some restrictions.
For details on the DVCAM/DV format compatibility, see
Compatibility of DVCAM and DV Format on page 99

playback, fast-forward, rewind, slow-play, still, cue
and review modes.
Notes
