Warnings and Precautions
1. Read all of these warnings and save them for later reference.
2. Follow all warnings and instructions marked on this unit.
3. Unplug this unit from the wall outlet before cleaning. Do not use liquid or aerosol cleaners. Use a
damp cloth for cleaning.
4. Do not use this unit in or near water.
5. Do not place this unit on an unstable cart, stand, or table. The unit may fall, causing serious
damage.
6. Slots and openings on the cabinet top, back, and bottom are provided for ventilation. To ensure
safe and reliable operation of this unit, and to protect it from overheating, do not block or cover
these openings. Do not place this unit on a bed, sofa, rug, or similar surface, as the ventilation
openings on the bottom of the cabinet will be blocked. This unit should never be placed near or
over a heat register or radiator. This unit should not be placed in a built-in installation unless
proper ventilation is provided.
7. This product should only be operated from the type of power source indicated on the marking label
of the AC adapter. If you are not sure of the type of power available, consult your Datavideo dealer
or your local power company.
8. Do not allow anything to rest on the power cord. Do not locate this unit where the power cord will
be walked on, rolled over, or otherwise stressed.
9. If an extension cord must be used with this unit, make sure that the total of the ampere ratings on
the products plugged into the extension cord do not exceed the extension cord’s rating.
10. Make sure that the total amperes of all the units that are plugged into a single wall outlet do not
exceed 15 amperes.
11. Never push objects of any kind into this unit through the cabinet ventilation slots, as they may
touch dangerous voltage points or short out parts that could result in risk of fire or electric shock.
Never spill liquid of any kind onto or into this unit.
12. Except as specifically explained elsewhere in this manual, do not attempt to service this product
yourself. Opening or removing covers that are marked “Do Not Remove” may expose you to

Introduction
DAC-5 is designed to convert SDI video and AES/EBU audio to and from compressed DV audio/video. It
encodes SDI, AES/EBU digital Audio to the DV format and sends the DV stream on the IEEE-1394
interface and it decodes the DV stream arriving on the IEEE-1394 interface and converts it to SDI and
AES/EBU Digital Audio output.
Features Video/Audio output of component YUV, Y/C, composite video and unbalanced stereo audio for
monitoring.

Installation
Connection:
1 DV In/Out
Connect a DV source to one of the DV connectors at the rear of the DAC-5 for input and output. Source
must comply with IEEE-1394 (i.Link) standard. Two 6-pin DV connectors effectively provide active
loop-through when the unit is turned on.
2 SDI In/Out
Connect an SDI signal to the SDI input BNC connector (left-hand side) labeled SDI. The DAC-5 accepts
4:2:2 serial digital video signals in either 525 or 625 line formats. The input signal must conform to the
SMPTE 259M standard. Connect destination equipment to the SDI output BNC connector (right-hand side).
The DVITC timecode in the output signal respects the same standard as the one in the input signal.
3 AES In/Out
Connect an unbalanced AES signal to the AES input BNC connector labeled AES. DAC-5 supports 48 kHz
digital audio sample rates. This signal must comply with the AES-3id-1995 (SMPTE 276M) standard.
Connect destination equipment to the AES output BNC connector.
4 Monitoring Output
Connect analog destination equipment to the connectors at the rear of the DAC-5. Use the BNC labeled
Composite or the mini-Din labeled S-Video for video output; use the two RCA labeled R and L for audio
output.

Troubleshooting
1- When using some camcorder models as a DV source, the DV signal may be lost if
you try to unplug the iLink cable from the DAC-5 during the transmission. To recover
from this situation, turn the camcorder off and then on again.
2- Turn-on the DAC-5 before launching any editing software
3- Macintosh users will have some problems if they try to toggle the video format (525 to
625 or 625 to 525) in the same session; they will not be able to correctly process the
video sequences in the new format. The DAC-5 must be powered on and in the right
video format (even if no input signal is connected to the unit) before attempting to
start the computer and launch the editing software.
