Features
Compact size and light weight
This editor is an integrated editing system which
delivers two DVCPRO 50 digital VTRs, an editing
controller, two LCD monitors and speakers in a single
unit.  It features a compact, lightweight and portable
design which enables it to be easily carried around
and readily utilized for editing work on an office desk,
etc.
Cut editing
This unit is capable of both assemble editing and
insert editing.  With insert editing, the signals of each
of 4 audio channels can be edited separately.  In the
DVCPRO format (25 Mbps), only two audio channels
are supported.
Full range of editing functions
The editing control area is equipped with a numeric
keypad to enable more sophisticated editing
operations.  The keys also make it easier to process
the edit data.
Included among the unit’s many editing functions are
split editing, still-picture/slow-motion editing and multi-
event editing.
High picture quality
A high picture quality is achieved through 4:2:2
component signal recording (DVCPRO 50) which has
twice the recording rate of the existing DVCPRO (25
Mbps) format.
Both DVCPRO formats supported
The unit is capable of recording and playing tapes in
the existing DVCPRO (25 Mbps) format as well.
525i/625i systems switchable
Either the 525i (interlace) system or 625i system can
be used by making this selection on a setup menu.
OThe analog component and analog composite input
facilities are used exclusively by the 525i system.
They do not have a system conversion function.
O625i system editing is restricted to editing involving
the VTR1 
5VTR2 internal connections.
L and M size cassettes supported, recording up to
92 minutes
The L cassette delivers a maximum of 92 minutes of
recording (using the AJ-5P92LP).  Up to 184 minutes
of recording are possible with the DVCPRO (25 Mbps)
format (using the AJ-P184LP).
SDI interface
This unit is equipped with a 4:2:2 serial digital
interface as a standard feature.Functional input/output interfaces
OAnalog input and output facilities:
Both VTRs come with video
(composite/component) and audio input and output
connectors.
Analog video signals cannot be input in the 625i
mode.
O9P remote connector: (525i mode only)
Both VTRs come with 9P remote connectors to
enable an external controller to operate the unit by
remote control.
The 9P remote connector of VTR1 can be switched
to remote OUT, and an external VTR can be
controlled using the control system of VTR1.
OTime code input and output facilities:
The unit comes with one time code input connector
so that the time code generators of both VTR1 and
VTR2 can be synchronized to an external time
code.  VTR1 and VTR2 each have a time code
output connector.
7-inch wide-screen LCD monitors
On-screen settings
Highly individualized settings can be performed on-
screen.
Centralized displays using fluorescent display
tubes
Fluorescent display tubes, which are easy to read
even in poorly lighted places, are used to indicate the
counter displays, audio meter levels, VTR modes and
other statuses.  This means that all the displays are
grouped together in a central location.
