PIO GOVERNMENT CENSORSHIP SCREENING ROOM Nicosia, Cyprus
And the sound system. Not much, but does the job just fine. Top is a Harman Kardon Prologic A/V amplifier driving the main speakers and subwoofer pre-out and below a Kenwood second amplifier driving the surround speakers. The mixer contains balanced inputs from both machines on separate channels for left and right for each machine so we are using 4 channels on the mixer to be able to balance the sound correctly (hf/gains etc). A 4-pole relay was installed at the base of each projector and when the dowser is raised the relay allows the sound to pass to the mixer. It works beautifully as the changeover flawlessly drops the dowser of the other projector when starter.
