My Pick:

Sigma Electronics VDA26 composite video distribution amplifier,

What I Like About It:

Two outstanding features of this handy, standalone, compact 1x6 composite video distribution amplifier (VDA) are its ruggedness and reliability. The Sigma Electronics VDA26 is the size of a medium-thickness paperback book. Besides being light and portable, three of these units will mount side by side in an optional factory rack frame.

I particularly like the amplifier's all-metal construction, which helps shield against stray EMI/RFI leakage — a common nuisance with the SMPS (switch mode power supply) on older light dimmer packs. I also prefer the professional-grounded, three-wire AC cord instead of the wall-wart system.

I Would Change:

About the only thing I could ask for would be to add an auto-terminating 75-ohm looping input to the VDA26. Some other units require sliding a switch to terminate, while this model requires the user to add a BNC-type terminator to be manually connected for proper loading of the signal if you're not going to loop it.

Where I Used It:

I frequently use the Sigma Electronics VDA26 for concerts at the Meadowbrook Musical Arts Center in Gilford, NH.
