+ | The camera gets its audio signal from a separate audio case. | ||
+ | |||
+ | === Encoder PC | ||
+ | * Intel Core i7 6700K | ||
+ | * 16 GB RAM | ||
+ | * 2 Blackmagic Design DeckLink Mini Recorder (one for SDI to the camera, one for HDMI to the Zidoo and subsequently the speaker laptop) | ||
+ | |||
+ | === Audio Case | ||
+ | The audio case consists of three wireless receivers feeding into a mixer that is subsequently fed into the camera, and (if necessary) the PA. | ||
+ | The receivers are paired with one handheld transmitter, | ||
+ | To power the receivers and provide them with signal, while only using one pair of antennas, we use a antenna splitter. | ||
+ | * Mixer: Mackie 1202 VLZ4 | ||
+ | * Receivers: 3 Sennheiser EM 100 G3 1G8 | ||
+ | * Splitter: Sennheiser ASA 1 1.8GHz | ||
+ | * Handheld transmitter: | ||
+ | * Body packs: 2 SK 100 G3 1G8 | ||
+ | * Lavalier Clip-ons: 2 Sennheiser MKE2-EW Gold | ||

+ | === Misc | ||
+ | * We have our custom slides software, so the Camera1 doubles as a presenter for slides, which is why it is hooked to an active hdmi splitter, and the splitter is connected to both the projector and the grabber. | ||
+ | * With our custom slides software, we have a dumb android app on a tablet that lets the speaker draw over the slides. | ||
+ | * The camera 1 is fixed and has 2 cheap [[http:// | ||
