+Currently we use the decklink cards in combination with a [[hardware:tronsmart_pavo_m9]] as slide grabber and
 have to types of [[hardware:cams]] which we connect via SDI to decklink cards.
 In the past we used [[hardware:epiphan-broadcaster]] via IP as slide grabber but we where unhappy with delay and compatibility of these devices.
 We feed Audio via XLR right to the camera which embedds it into the SDI signal. We have four [[hardware:audiocase]] which we use if the venue is no
 providing a better audio system.
 == CCC Cologne
+The CCC Cologne uses a setup very similar to the [[software:voctomix-hardware-examples#c3voc|C3VOC]]. Voctocore runs on a Encoder PC, while the voctogui is running on a club member's laptop.
+We connect the Encoder PC to a [[hardware:ag-ac-160-eej|Panasonic AG-AC 160 AEJ]] mounted on a Sachtler ACE M MS, as well as a [[hardware:zido_x8_x9|Zidoo X9]] used as a cheap video scaler.
+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, 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.
+* Mixer: Mackie 1202 VLZ4
+* Receivers: 3 Sennheiser EM 100 G3 1G8
+* Splitter: Sennheiser ASA 1 1.8GHz
+* Handheld transmitter: SKM 100-835 G3 1G8
+* Body packs: 2 SK 100 G3 1G8
+* Lavalier Clip-ons: 2 Sennheiser MKE2-EW Gold

 There are still some sync issues with this setup.

+== 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.
