DVMC-DA1

-US

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.

-US

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 cord, and do not place the product where the power cord is subject to wear or abuse.

following the operating instructions. Adjust only those controls that are specified in the operating instructions. Improper adjustment of other controls may result in 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.

• Do not attempt to service the product yourself since 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. Clean the product with a dry, soft cloth, or a soft cloth slightly moistened with a mild detergent solution. Do not use any type of solvent, such as alcohol or benzine.
