Random Blanking on muti tv business installation.

I have 2 identical venues with 12 direct TV receivers.   Each has many Vizio and other brand tvs.  Both venues I have the same identical HDMI over cat 6 product for transmission.

Venue one works perfectly.

Venue 2  I get intermittent 1 second black screens from time to time and occasional copyright protection messages randomly on many tvs.  

Venue 1 has this direct TV equipment (first 4 Photos) Notice the amplifier. Venue 2 is next 3 photos no amplifier. 

Could an amplifier be used at Venue 2?
