This instruction manual is for both the DXC-325 series
(DXC-325K/325L/325H) and the DXC-325P series
(DXC-325PK/325PL/325PH) color video cameras. These two
types of cameras are designed for different signal systems,
the NTSC and the PAL systems. So each type of camera
must be used with the equipment which matches its signal
system, but the operating procedures for both series are the
same. The DXC-325 series is for the NTSC color system, and
the DXC-325P series is for the PAL system.

Features and Notes on Use
The DXC-325/325P is a newly designed portable color
video camera employing three 1/2-inch Charge Coupled
Device (CCD) imagers each having a total of
250,000/290,000 (for the NTSC and PAL models
respectively) effective picture elements. The
DXC-325/325P is normally used with the CA-325/325P
camera adaptor as a single camera unit, but, if necessary,
it can be separated from the camera adaptor and can be
used with a variety of different units which will be
introduced in the market in the near future. The camera
can be used for outdoor recording when used with a
portable video cassette recorder, and can also be used as
a studio camera when connected to a CCU- M3/M3P
camera control unit.
Adoption of CCD
¢ Incorporation of a CCD results in a compact, lightweight
camera body which consumes less power than
does a camera using pickup tubes).
¢ Low lag, high resistance to image burning and no
deflection distortion.
¢ The CCD is not affected by vibration and mechanical
shock.
¢ The CCD imager is not influenced by terrestrial
magnetism.
© Thanks to the high signal-to-noise ratio, the video output
level can be raised by 9 dB or 18 dB to obtain a clear
picture under low light conditions.
¢ The electronic shutter is built into the imagers and
enables the DXC-325/325P to produce clear images even
when the objects it is shooting are moving at very high
speeds. The advantages of this function are most
obvious during playback of still or slow motion pictures.
Various connection capability
¢ The camera can be used as a studio camera when
connected to a CCU-M3/M3P camera control unit.
* The camera can be connected to an S-VHS format VTR.
¢ If aspecial adaptor (will be introduced in the near future)
is attached to the DXC-325/325P camera head, it can
output an RGB format signal.
Power sources
© A compartment for the NP-1A battery pack is built into
the camera adaptor. The camera and 1.5-inch viewfinder
can be used for about 120 minutes with a fully charged
NP-1A (optional).
© The power can be supplied to the camera from a
portable VTR or from the CCU-M3/M3P camera control
unit.
* A CMAS/8CE camera adaptor (optional) is needed if the
camera is to be used with the AC power source.
| Features
Automatic adjustment and memory functions
¢ The white balance and black balance are automatically
adjusted by a microcomputer, and the adjusted values
are retained for about 12 hours while the camera’s
power is off.
¢ The black level drift is automatically adjusted, together
with the black balance.
¢ lf the entire picture is too bright, the black level is
lowered to the appropriate level by the automatic black
level (ABL) adjustment so that a picture with good
contrast can be obtained.
Display and related functions
¢ The character generator built into the camera displays
title characters to be inserted on the viewfinder or
monitor during recording.
¢ In addition to title characters, the operational status of
the camera and the warning indications are also
displayed on the viewfinder.
¢ The REC indicator on the viewfinder blinks if a VTR
malfunctions.
¢ Zebra pattern appears on the viewfinder screen when
the video output level is about 70 to 80 IRE (for NTSC
model) or 490 to 560 mV (for PAL model). This pattern
provides a useful reference when the operator manually
adjusts the iris.
Cordless electrical connection to the VCL-810BX
camera lens unit
e The DXC-325/325P is equipped with a pin-type lens
connector which connects directly to the electrical
circuitry of the lens unit. The lens can thus be controlled
from the video camera without using a lens cable.
Location of controls to avoid misoperations
¢ The switches which are not used frequently are located
behind the cover on the side panel so that you can
forget about possible misoperations while you are using
the video camera.
Newly designed camera body and Iens grip
¢ The camera will be well balanced on your shoulder when
holding it with the lens grip. in addition, you can see to
your right over the camera body while you are shooting.

DXC - 325P (EK)

| Precautions
Safety
© Do not try to mount a 2/3-inch lens directly on the
DXC-325/325P.
Be sure to attach an LO-32BMT lens mount adaptor
(optional) to your 2/3-inch lens if you want to mount it.
* Operate the camera only on 12 V DC. For operation from
an AC power line, use the camera adaptor
recommended for this camera.
¢ Allow adequate air circulation to prevent internal heat
build-up.
Operation
© Avoid rough handling or mechanical shock.
¢ Do not operate the camera outside a—5°C to + 45°C
(23°F to 113°F) temperature range.
¢ Keep the camera in a horizontal plane.
¢ Keep the camera away from very strong magnetic fields
to avoid distortion and flutter on the screen.
* Do not hold the camera by the viewfinder.
Be sure to cover the lens with the supplied lens cap
when the video camera will not be used for a long period
of time.
The following phenomena may appear on the monitor
screen while the DXC-325 series color camera is used.
These phenomena are not indicative of a camera
malfunction.
Smear phenomenon
This may appear when a very bright object is shot.
Light beit-like line
(smear phenomenon)
A very bright object is shot.
(Electric light, fluorescent lamp,
sunlight, strong reflected light,
etc.)
Video monitor screen
DXC-325 (UC)
DXC-325P (EK)
Operation of the viewfinder
¢ Do not point the viewfinder directly at the sun, or the
plastic inside the viewfinder may be damaged.
* The picture on the viewfinder screen may be distorted if
it is used in strong magnetic fields.
Cleaning
Clean the cabinet, panel and controls with a dry soft
cloth, or soft cloth lightly moistened with a mild detergent
solution. Do not use any type of solvent, such as alcohol
or benzine, which might damage the finish.
Repacking
Do not discard the carton. It affords maximum protection
whenever the camera is transported. Do not transport or
ship the camera only in the carrying case. Repack it as it
was originally packed at the factory.
If you have any questions about this camera, contact your
authorized Sony dealer.
Special Characteristics of a CCD
White dots
White dots may appear in the video output if the camera
is used under very high temperatures.
Wavy pictures
This may appear when fine stripes, straight lines, etc, are
shot. Their images monitored on the screen look waty.
Note on the electronic shutter
If the GAIN selector is set to the 18 (dB) position when the
electronic shutter is used, a clear picture may not be
obtained. Use the electronic shutter under the lightirg
conditions under which a clear picture is obtained wth
the GAIN selector set to the 0 or 9 (dB) position.
