Videotek VDA-16 Video DA

Videotek manufactured a line of Video (and Audio) Distribution Amplifiers for use in Broadcast installations where High quality, dependability, and space were all at a premium.   These DAs are very well constructed with internal power supplies, Isolated Inputs and outputs, and front panel Level & EQ controls, and test points.

All 12 DAs have been retested thouroughly: all 6 outputs, Level and EQ adjustments, hum & noise measurements.  They all are in excellent working condition.

There were several trim packages over the years, and all of these are in the charcoal grey case style, with BNC jacks and a looping input.   Most were removed from Master Control room & Edit Suites and have never travelled.  Videotek was taken over by Leitch who continued to manufacture the VDA-16.

If you are in need of a rackmount shelf, please let us know.    There are a limited number on hand at the time of this listing, and they are available with a purchase of 2 or more DAs for an additional $15.
