≥

The VTR unit compresses the images using a component
digital recording system that uses the latest compression
technology, and for the sound it employs non-compression
PCM recording with an excellent signal-to-noise ratio,
frequency band, waveform characteristics and reproduction
characteristics of the finely detailed areas.  As a result, both
the picture quality and sound quality are taken to new
heights of excellence.
A choice of recording formats tailored to the application at
hand is offered: the DVCPRO50 format when priority is
required to be given to the picture quality, and the DVCPRO
format when economy is to be given precedence.

<Note>
When the unit is used in the 24P or 24PA camera mode,
care should be taken in handling as the images may be
disrupted for an instant due to the fact that the correlation
between the time code and image phases is synchronized
using a 5-frame sequence.
This image disruption will occur two or three seconds after
the power has been turned on and when the mode is
switched from 60i or 30P to 24P or 24PA.

≥

In order to reduce its power consumption efficiently, the unit
has a function that shuts down circuitry that is not required
for the particular VTR mode established at the time.  This
enables the user to perform operations while conserving
power.

≥

When the AJ-YA903G expansion board has been installed
in the unit, this function makes it possible to start recording
the images and sound up to 15 seconds before the VTR
START button or the VTR button on the lens is pressed.
This comes in handy to ensure that no shooting
opportunities are passed up.

≥

This unit is capable of interval shooting.  Also, when the AJ-
YA903G expansion board is installed, memory control
enables one-shot recording in 1-frame increments (in the 60i
or 30P mode), which is the shortest recordable time, and
also in 5-frame increments (in the 24P or 24PA mode). This
is quite useful when it comes to shooting programs on
science or the natural world.  If the selection is set to the
one-shot recording function, single frames can easily be
shot.

≥

This function especially supports shooting in the context of
news gathering or documentary filming to ensure that no
opportune shutter opportunities are passed up.
By controlling the start key acknowledgment time, the unit
can continuously record without the user having to interrupt
the recording: this safeguards against the failure to record
those precious moments—a failure that occurs when
recording is resumed after it has been shut down
temporarily.

≥

This function is for not leaving behind superfluous cuts when
a cut turns out to be no good during the shooting of news,
reports or art programmes.  By cutting down on the time
taken for copying onto the work tape, for instance, this
function is very effective in achieving economical operation.
Users should remember to handle this function very
carefully.

≥

When the AJ-YA903G expansion board has been installed in the
unit, SDI signals can be output from the VIDEO OUT connector.

≥

The unit enables the audio input signals in four channels to
be selected separately.  Further, the level of the signal in
each channel can be monitored on the LCD display window.

≥

The unit’s front panel is equipped with a control for adjusting
the audio recording level.  This is useful when the user is
filming on his or her own and the audio level needs to be
adjusted.  It also is possible to cancel the effect of this control.

≥

The unit’s construction supports a slot-in wireless receiver
which is available as an optional accessory.

≥

The CUE audio recording circuitry contains a Dolby B noise
reduction circuit.
