Why this kit

An auditorium has to capture questions from the floor. This tier does that with two UHF handhelds passed along the rows, through the PA mixer, so the hall hears the question and so does the stream. The ceiling array that needs no handheld is a swap on a quote, because it depends on your ceiling and a site survey. Two PTZs on SDI let one hold a wide safety shot while the other tracks, and BNC is the only sane choice over auditorium cable distances. Their 5x optical lenses work from within about 15 m of the stage, so fix them at the front of the balcony or on the side walls rather than on the rear wall. The Television Studio HD8 ISO records every input to a drive while the HyperDeck records an independent archive, so one failed disk does not lose the lecture, and the switcher streams by itself with no separate encoder. The cable pull and the mounting are your installer's job. The handhelds are UHF, so have the installer check the band at your site. They are the line that keeps this kit on a quote: we confirm their price there. A 2.4 GHz handheld passed through a full auditorium, under its own PA, is the thing that fails at the event, so we have not substituted one; for a smaller room, the better kit does that job.
