To take best advantage of the many features ofthis unit, note the following
important points.
Usable cassette tapes (seepage 3-3(E))
Use only metal cassette tapes with this unit. Donot useoxidetapes.
Reference videoinput(seepage3-5(E))
When recording or playing back videotapes on thisunit,always inputa composite
video signal synchronized with the video signal to be used to the REF. VIDEO
INPUT connector. Especially when recording and editing, failure to inputa
reference video signal to the REF. VIDEO INPUT connector will prevent the built-
in time base corrector (TBC) from functioningcorrectly, causing picture breakup.
Even ifyou are recording only audio signal or time code, do not fail to input a
reference video signal.
Inputvideo signaltype selection (seepage 4-5(E))
For recording, it is important that the VIDEO IN switch on the subsidiary control
panel is correctly set to match the type ofvideo signal input. In particular, when
inputting a component signal, set this switch to the "Y-R,B" position, and set the
component signal input connector selection switch on the rear panel to the
appropriate position. Ifthese switches are not setcorrectly, not only will recording
not be possible, but the input signal will alsonot appear on the monitor.
Setting the cassetterecord-inhibitplug (seepage 3-4(E))
Recording on a cassette is impossible when its record-inhibit plug is pushed in.If
the record-inhibit plug ispushed in on the cassette you are going to use, either use
anew tape, or pull out the plug and use the tape after making sure that it contains
no important material.
Controlling tape transport remotely (seepage 7-3(E))
The tape transport buttons on this unitare normally disabled when the REMOTE
indicator islit. However, you can use these buttons ifyou set the LOCAL
ENABLE menu item to ALL ENABLE. The factory default setting for this item is
STOP & EJECT.
Storingina rack
When installing this unitin a standard 19-inchrack, you can stack up to three units
inone rack. When stacking four or more units, be sure to leave space equivalent to
oneunit height, or 44.45 mm (1 3/4inches) between units.

Chapter1
Overview________
This chapter overviews the features ofthe UVW-1800/1800P.
Features.........................................................................1.2(E)

The UVW-1800/1800P is a Betacam SPvideocassette recorder, capable of
recording and playing back composite video, component video and analog audio
signals. With an external control unitconnected, jog and shuttle functionsare
available, and the unit can be used asthe recorder in an editing system.
Betacam SPformat
Excellentvideo and audiocharacteristics
Compared with a conventional format, Betacam SP format provides better video
and audio performance, with improved signal-to-noise ratio, frequency
characteristics, and detail reproduction, and greatly enhanced overall video and
audio quality.
Compatibilitywith other Betacam SP VTRs
Ametal tape cassette recorded on this unit can also be played back on other
Betacam SP VTRs. Again, metal tape cassettes recorded on other Betacam SP
VTRs can be played back on the UVW-1800/1800P. The cassette size isdetected
automatically.
Fullrangeof recording and playback functions
Built-intime code generatorand reader
The built-in time code generator allows the unitto record time codes(LTCoruser
bits) simultaneously with the video and audio signals. The built-in time code
reader allows the unitto read time codes (LTC or user bits) from a tape.
Built-intime basecorrector (TBC)
The built-in time base corrector allows you to obtain a stable playback picture with
no horizontal jitter or color fluctuation.
Microprocessor servo system
Four microprocessor-controlled DC motors provide direct drive for the drum,
capstan and reels, enabling quick and accurate tape access.
Audio noisereduction
Longitudinal audio tracks 1 and 2 use the same Dolby C-type noise reduction
21 asa
conventional Betacam SP system. These circuits are always operating when
recording or playing back.
1)Because this unitdoes not record the AFM carrier 2) Dolby noise reduction manufactured under license
wave, noise may be heard when tapes recorded on from Dolby Laboratories Licensing Corporation.
this unitare played back by other VTRs in the BVW "DOLBY" and the double-D symbol DO are
series.If necessary, lower the audio levels oftrademarks ofDolby Laboratories Licensing
channels 3 and 4 on the other VTR. Corporation.
-|-2 (E) Chapter 1 Overview

Otherfeatures
Compact, power-saving design
The unit islight and simple, and very energy-efficient.
Menu-basedset-upsystem
All the initial settings for system operation conditions and soforth areaccessed
through a simple menu system, from the subsidiary control panel.
Remotecontrolfunction
The unit can be operated from a remote control unit through the RS-422A serial
interface.
Itisalso possible to use the CONTROL S connector on the front panel to connect a
simple remote control unit(SIRCS type remote control unitsuch as an SVRM-100)
to carry out search operations.
Digitalhoursmeter
The digital hours meter keeps cumulative totals offour values: the total hours
powered on, the drum rotation time, the tape running time, and the numbering of
threading/unthreading operations. These are displayed assuperimposed text on the
video monitor.
Superimposed text output
The VIDEO 2 (SUPER) OUTPUT connector provides a monitor video output
which can have various information (time codes, tape speed, system settings, etc.)
superimposed on it. The superimpose function can be enabled ordisabled as
required.
S-Video connectors
With VTRs or other peripheral equipment having S-Video connectors, these
connectors provide a high-grade interface for video signal transfer.
Self-diagnosis functions
Ifan operating faultoccurs, the system attempts todiagnose the problem, and
produces an error codeon the time counter display and superimposed video output.
Alarm indications
Ifan erroneous operation or connection is made, the system superimposes
information on the monitor screen giving nature ofthe error and actions to be
taken. The cause ofthe problem isalso indicated in the time counter display.
