= Voctomix hardware examples

This page aims on documenting some real world setup used by groups / individuals around the world

== C3VOC

The c3voc is currently running voctomix on our 6 Encoder PCs the voctogui runs on our Mixer laptops.
Currently we use the decklink cards in combination with a Tronsmart Pavo M9 as slide grabber and
have to types of Cameras and tripods which we connect via SDI to decklink cards.
In the past we used 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 Audio case 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 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 Panasonic AG-AC 160 AEJ mounted on a Sachtler ACE M MS, as well as a 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

== CCC Berlin The CCC Berlin setup is currently an experimental setup. We currently run there an JVC HM300 cammera which has IP based streaming build in which we feed to voctomix. We also have there a tronsmart grabber box which also can stream to voctocore. There are still some sync issues with this setup.

The Audio setup for CCCB can be found 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.

=== Sources

Camera 1: Raspberry Pi with camera.

Camera 2: Raspberry Pi with camera.

Slides: Lenkeng LVK373a (see: reverse engineering)

Audio: Odroid U2 connected via USB to our audio mixer

=== 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 servos to make it move.

The camera 2 is on a tripod powered via PoE.
