Two Year Limited Warranty

All Video Accessory Corporation (VAC) products have a full two year limited warranty. Exclusions to the warranty include but
are not limited to damage to external components, power LED failure where the product continues to function, and electrical damage due to
lightning. The warranty shall be void if any alteration or repair of a VAC product is attempted by anyone not authorized by VAC. This war­ranty is expressly in lieu of all other warranties express or implied, including warranties of merchantability and fitness for use, and of all
other obligations or liabilities on the part of VAC, and it neither assumes nor authorizes any other person to assume for it any liability in
connection with the sale of this product. This warranty shall not apply to the product or any part thereof subjected to accident, negligence,
alteration, abuse, or misuse. No warranty whatsoever is made with respect to accessories or parts supplied by anyone other than VAC, and
this warranty shall extend only to the original purchaser of this product. The warranty provided in this article is exclusive and in lieu of, and
buyer hereby waives, all other remedies, express or implied, arising by law or otherwise, including consequential damages, whether or not
occasioned by negligence of VAC. This warranty shall not be extended, altered or varied except by written instrument signed by VAC and
buyer, and shall only apply within the boundaries of the continental United States. Liability of VAC is limited to repair or replacement at
the option of VAC. Warranty work is to be sent to VAC. Freight charges will be the responsibility of the purchaser.

Power:

12V AC - The 12V AC Brick™ is designed to function properly with an input power of 11-13V AC.

The Brick will not operate from a DC voltage. A 2.1mm P5 style connector is used for the power input. If
the input voltage is a grounded system, the center pin of the P5 is the power connection and the barrel is the
ground side. All ProSeries units are shipped with a 12V AC, 600mA floating power supply that eliminates any
ground loops through the power supply connection.

FlewPwr - The FlexPwr Brick™ is designed to function properly with an input power of 10-28V AC
(ungrounded) or 12-32V DC (grounded or ungrounded). A 2-pin header (Phoenix Contact #1881448) style
connector is used for the power input. The 12V AC, 600mA wall transformer provided with the product pro­vides a floating power source that has been designed to eliminate any ground loops through the power supply
connection.

Input:

These products combine four composite video 1X2 distribution amplifiers into a compact, rugged, and
low-cost package. It is the ideal solution where a small number of video channels are required. Each of the
four video channels within these products is a separate circuit, and each output is individually buffered. The
units have either BNC or RCA connectors. Unused outputs are not required to be terminated; nor will a short
or open circuit condition on any output affect any other output. Likewise, a short or open circuit on any input
will not affect any other input. A video signal with excessive DC component (or offset) such as those generat­ed by many computer video boards will cause the VAC Brick to malfunction. The 1Vpp video signal needs to
be within -1V to +1V. Ideally, the video signal's blanking level should be clamped to 0 volts, although an AC
coupled signal is also acceptable.

Common Signal Ground:

Please note that all four DA circuits in the product share a common ground; VAC does not recommend

Quad DA products for applications requiring ground isolation for each channel.

Outputs:

The VAC Brick has four 1X2 video distribution amplifers. The units have either BNC or RCA connec­tors. Each output has a series impedance of 75 Ohms. Unused outputs do not need to be terminated for proper
operation of the Brick. Using terminators on unused outputs provides additional protection for the Brick from
ESD (static electricity) events.
