1-7. CONNECTIONS AND OPERATION
1-7-1. Recording and Playbac~
An example of a basic connection for
recording and playback is shown below.
For a recording signal connection: Connect
the COMPOSITE DIGITAL OUTPUT connector of
the PCM-1630 to the composite digital
(video) input connector of recorders such
as the DMR-2000/4000, BVU-800DB (
0).
For a playback signal connection or
connection for monitoring in the E-to-E
mode: Connect the composite digital
(video) output connector of the recorder to
the COMPOSITE DIGITAL INPUT A connector of
the PCM-1630 (set the PB MODE selector of
the PCM-1630 to A) (
0).
75-ohm coaxial cables (BNC-BNC)~~~
( 1-551-475-51)
0
When a DMR-2000 or DMR-4000 recorder is
used in the system, connections
0
and
0
can be replaced with a single connection
with an 8-pin multi-cable (
®).
In this
case, do not make connections
0
and
@
simultaneously.
Notes
• Since the recorder's servo must be locked
to the sync signal from the PCM-1630
during playback, supply a composite
digital signal or a composite sync signal
from the PCM-1630 to the recorder.
• The recording and playback modes can be
alternated by pressing the appropriate
buttons on the recorder. When a
BVU-800DA/DB recorder is used, always set
the recorder's dropout compensator
circuit to OFF and its framing servo to
ON.

1-7-2. Digital Dubbing
When two recorders (a recorder for playback
and a recorder for recording) are used in
the system, a tape can be duplicated
without degrading the sound quality. Make
the following connections.
For a connection vith a player: For a
playback signal connection, make connection
(D
shown below between the PCM-1630 and the
player. For a reference signal connection
for the servo, make connection
0
or
® .
For a connection vith a recorder: For a
recording signal connection, connect the
PCM-1630 and the recorder as shown with
G).
For playback after digital dubbing,
connect the COMPOSITE DIGITAL INPUT B
connector of the PCM-1630 to the video
output connector of the recorder as shown
with
®.
To duplicate
Set the selectors on the PCM-1630 as
follows:
ENC IN selector: DUBBING
DA IN selector: INT
PB MODE selector: A
Set the player to the playback mode and the
recorder to the record mode. Digital
dubbing will begin.
To play back the duplicated tape
It is possible to play back the duplicated
tape simply by setting the PB MODE selector
on the PCM-1630 to B, without changing the
connections. (Setting the ENC IN selector
on the PCM-1630 to ANALOG or DIGITAL is
recommended. l
Notes
• For digital dubbing, set the FS selector
(SWll on the SIF-1 board of the PCM-1630
to the appropriate position, in
accordance with the sampling frequency
(indicated by the FsiD indicator on the
front panel of the PCM-1630) of the tape
on the player.
• The emphasis identification bits on the
tape being played back are recorded on
the tape in the recorder. The setting of
the EMP switch (SWll on the AD-23 board
of the PCM-1630 does not affect digital
dubbing.
• When the recorder is in the E-to-E mode
(the stop model during the digital
dubbing operation, a loop of the
recording signal and the playback signal
may oscillate noise. This is not a
malfunction. When this ~ccurs, turn down
the volume to avoid speaker damage.
