 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, and two body packs connected to lavalier clip-on microphones.
-To power the receivers and provide them with signal, while only using one pair of antennas we use a antenna splitter.

 The Audio setup for CCCB can be found [[:chaosradio | here]]
+== David's setup
+This is probably the cheapest vocto setup you can find. All the sources run on separate devices (!) and are encoded into a single stream by our server.
+* [[https://github.com/DavidVentura/voctomix/tree/dev/prod_scripts]]
+=== Sources
+* Camera 1: Raspberry Pi with camera.
+* Camera 2: Raspberry Pi with camera.
+* Slides: Lenkeng LVK373a (see: [[https://blog.danman.eu/new-version-of-lenkeng-hdmi-over-ip-extender-lkv373a/|reverse engineering]])
+* Audio: Odroid U2 connected via USB to our audio mixer
+=== Sources & Voctocore
+==== Producers:
+* Camera 1: gstreamer with rpicamsrc serves an h264 stream with matroska container with tcpserversink
+* Camera 2: gstreamer with rpicamsrc serves an h264 stream with matroska container with tcpserversink
+* Audio: Feeds the audio directly to vocto in the desired format
+* Slides: Unicast/multicast to the network
+==== Consumers:
+On the server I host voctocore I run the following scripts
+* Camera 1: Grab data from the camera1 tcp server, decode it and feed it to vocto
+* Camera 2: Grab data from the camera2 tcp server, decode it and feed it to vocto
+* Slides: Connect to mcast group, decode and feed it to vocto
+=== Hardware
+* Audio mixer: Behringer Xenyx Q502usb
+* Microphones: (2x) Skp Uhf271
+* Grabber: Lenkeng LVK373a
+* Server: i7 4790 + Gigabyte motherboard + 8GB Ram
+=== 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://www.conrad.com/medias/global/ce/2000_2999/2000/2090/2090/209089_LB_00_FB.EPS_1000.jpg|servos]] to make it move.
+* The camera 2 is on a tripod powered via PoE.
