Overview
The DVMC-DA1 is a media converter unit which converts analog video
signals to digital video signals and vice versa.
Converting pictures and sound from 8 mm/VHS format to
DV format and vice versa (pages 8 - 10)
You can convert analog video on Hi8, 8 mm, or VHS format cassettes to
digital video (DV) by connecting both analog and digital video units
via the media converter. MPEG data cannot be converted as a digital
signal.
Since pictures and sound are recorded on the DV unit in digital format,
little or no picture and sound quality are lost.
You can also convert digital video to analog video.
Note
You cannot record video which includes copyright protection signals.
Viewing pictures from the DV unit (page 11, 12)
You can enjoy high quality digital video when you connect a DV unit to
a TV via the media converter using the DV connecting cable.
In this case, you do not have to change the connection between your TV
and the other analog video unit.

Capturing images from an analog video unit using a PC
(page 13, 14)
You can capture images from an analog video unit connected to your
PC via the media converter using the DV (i.Link) connector.
In this case, you can edit a movie or add titles using your PC. You can
also print out the captured images using your PC printer instead of a
video printer.
Selecting the audio mode when recording to the DV unit
(page 9)
You can add messages or background music after recording.
When you record to the DV unit from an analog video unit, you can
select 16-bit audio mode for higher quality, or 12-bit audio mode for
adding messages or background music (post sound recording).
Listening to the audio with the desired mixing rate (page 12)
When playing back video recorded in 12-bit audio mode on a DV unit
via the media converter, you can listen to: the recorded message and/or
background music only (post sound recording), the original audio, or
the combined audio of both tracks with the desired mixing rate (5
steps).

Precautions
Use
• Operate the product only with the supplied AC power
adapter. If you use a different AC power adapter, it may
cause a malfunction.
Unified polarity plug
• Should any liquid or solid object fall into the cabinet,
unplug the product and have it checked by qualified
personnel before operating it further.
• Always turn the product off when you do not use it.
Unplug the product from the wall outlet if you are not
going to use it for several days or more. To disconnect the
cord, pull it out by the plug. Never pull the cord itself.
• Do not overload wall outlets, extension cords, or
convenience receptacles beyond their capacity, since this
can result in fire or electric shock.
• Do not use attachments not recommended by the
manufacturer, as they may cause hazards.
• Do not touch the AC power adapter with wet hands. If
you fail to observe this, it may cause electric shock.
• Do not drop or give a mechanical shock to the product.
Installation
• To prevent internal heat build-up, do not block the
ventilation openings.
• Avoid operating the product at temperatures below 5˚C
(41˚F).
• Do not subject the product to high temperature or direct
sunlight. If you do not observe the above instructions, the
product may become deformed.
• Do not place the product in locations where it is wet,
humid, dusty, smoky, or steamy. Do not use this product
near or around water. It may cause fire or electric shock.
Especially, do not use the product in the bathroom.
• If the product is transported directly from a cold to a warm
location, or if the room temperature has changed
suddenly, moisture may condense in the unit. If this
happens, let the moisture evaporate before using the
product.
• Do not place the product on an unstable cart, stand, table,
or shelf. The product may fall, causing serious injury to a
child or an adult, and serious damage to the product.
• Do not allow anything to rest on or roll over the power

damage and will often require extensive work by a
qualified technician to restore the product to normal
operation.
- When the product exhibits a distinct change in
performance –– this indicates a need for service.
• Do not disassemble or remodel the product. It may cause
fire or electric shock. Have the product checked and
repaired at your Sony dealer or local authorized Sony
service facility.

opening the cabinet may expose you to dangerous voltage
or other hazards. Refer all servicing to qualified service
personnel.
• When replacement parts are required, be sure the service
technician certifies in writing that he has used replacement
parts specified by the manufacturer that have the same
characteristics as the original parts.
Unauthorized substitutions may result in fire, electric
shock, or other hazards.
• Upon completion of any service or repairs to the product,
ask the service technician to perform routine safety checks
(as specified by the manufacturer) to determine that the
product is in safe operating condition, and to so certify.
• Unplug the product from the wall outlet before cleaning.

PRINTEDWIRING BOARDS AND SCHEMATIC DIAGRAMS
(For printed wiring boards)
•b: Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
• Through hole is omitted.
• Circled numbers refer to waveforms.
• There are few cases that the part printed on diagram
isn’t mounted in this model.
• Chip parts.
(For schematic diagrams)
• All capacitors are in µF unless otherwise noted. pF : µ
µF. 50V or less are not indicated except for electrolytics
and tantalums.
• Chip resistors are 1/10W unless otherwise noted.
kΩ=1000Ω,MΩ=1000kΩ.
• Caution when replacing chip parts.
New parts must be attached after removal of chip.
Be careful not to heat the minus side of tantalum
capacitor, Because it is damaged by the heat.
• Some chip part will be indicated as follows.
Example C541 L452
22U 10UH
TA A2520
• Constants of resistors, capacitors, ICs and etc with XX
indicate that they are not used.
In such cases, the unused circuits may be indicated.
• Parts with ★differ according to the model/destination.
Refer to the mount table for each function.
• All variable and adjustable resistors have characteristic
curve B, unless otherwise noted.
• Signal name
XEDIT→ EDIT PB/XREC →PB/REC
•2: non flammable resistor
•1: fusible resistor
•C: panel designation
•A: B+ Line *
•B: B– Line *
•J: IN/OUT direction of (+,–) B LINE. *
•C: adjustment for repair. *
• Circled numbers refer to waveforms. *
*Indicated by the color red.
