¶ How To
¶ Setup and use the tripod with Panasonic S1
You will need:
- the tripod bag with contents
- unpacked Panasonic S1 with lens, cage and tripod shoe (other attachments come later)
How to setup:
- Remove the tripod from its bag and unfold all legs to maximum - there are 3 thumbscrews per leg, make sure they are fingertight after extending the legs.
- Unfold the head handle - 1 thumbscrew
- Level the head base - losen the underside handle, use the spirit level to make it level, retighten the underside handle.
- Level the camera head - unblock the vertical break and move the head into position
- Tighten the horizontal and vertical brakes
- Place the camera upside-down on a table
- Make sure the camera is firmly attached to the cage and rotate the shoe to align with the lens direction
- Slide the camera from the back until the red button clicks - red button is a safety blocking the shoe from falling out
- Put the center of mass of the camera in the center of the head and tighten the shoe clamp
- Connect the camera with HDMI (socket on the left side of camera) to the AVX case via the "DSLM cam" input
How to use:
To rotate losen the horizontal and/or vertical brakes.
The silver rings control drag of the head from 0 (no drag, quick response) to 3 (full drag, smooth rotation).
The black wheel on the back is the counterweight - how much centering force is applied to the head.
Folding the tripod:
- Losen the shoe clamp and press the red button to release the shoe and slide it back.
- Put the camera upside down on a table and place the shoe sideways for storage
- Fold all legs of the tripod.
- Unscrew the handle and push it in a way that keeps the outline of the whole tripod assembly minimal
- Put the tripod in the bag - check which side is the head side.
¶ Pan Tilt Zoom camera setup
- Connect the PTZ camera LAN to the switch inside the case (via back panel) - power will be provided via PoE
- Connect the PTZ camera HDMI output to the "PTZ cam" HDMI input in the case
- Connect the control panel to the AVX switch in the case
- Turn the panel on
- Press and hold the "Camera Selection 1" button in the bottom row, after several seconds the panel will ask you if it should power the camera on. Select ON.
¶ Setup the mixing table
The default placement of the mixing table is shown in the picture, it's standing almost sideways in the passage from the main room to the electronics workbench.
- Place the case in the desired position
- Engage the wheel breaks by pushing down
- Unclip the front of the case - butterfly clips rotate 180° and unlock
- Unfold the legs - push a button near the hinge to unlock, make sure they click and stay in the right position
- Remove the top of the case - attach it to the leg side of the front
- Hook the studs into the side of the case - push the stud out to move it into place
- Make sure the studs are pushed to the bottom of the hooks of the case by pressing gently near the connection.
- Place the big screen on the table, connect its power, connect the HDMI cable to "1 HDMI" output on the case panel
- Open the back panel of the case and connect the power rail to the grid.
- Power on the PC (PC is mounted at the bottom of the case, power button is behind the door)
- Make sure the wireless keyboard and mouse are powered on and the USB dongle is plugged into a USB2.0 port in the front panel - if it's not the USB dongle is in the keyboard battery compartment
List of inputs and their purposes:
XLR mux box - NOT ETHERNET! - connect this to the XLR splitter box with a shielded 8 core cable
AUX1 - auxillary audio input
AUX2 - auxillary audio input
PTZ Cam - Pan-Tilt-Zoom camera HDMI input
DSLM Cam - Panasonic S1 camera HDMI input
Aux Cam - Auxillary camera HDMI input
Slides - Slides HDMI input from the presenter's laptop
LAN - connect to xHain network (the cable dangling from the cloud)
List of outputs and their purposes:
Display 1 - HDMI output for the main PC monitor
Display 2 - HDMI output for the secondary PC monitor
PA-MUX L R - left and right output the the amplifier system for the room (audience out)
Rec-MUX L R - left and right output for external audio recording
DMX - NOT AUDIO! - DMX light control signal
LAN Out - a port on the switch for any AVX equipment
¶ Use the Thomann wireless microphones
You'll find 4 Thomann wireless microphones in the microphone drawer in the AVX case. 2 of the microphones are hand held, 2 are transmitters with lav mics. All 4 are color coded: Yellow, Green, White, Magenta.
You'll find the receivers of the 4 microphones right above the Mic drawer (also color coded), they are wired permanently to the mixing table as inputs 1-4 (also color coded). Power for the receivers can be turned on with a button to the right of the receivers.
For now the belt transmitters with lav mics should be avoided (they pick up interference from mobile phones very easily).
The hand held microphones require 2 AA batteries. They're inserted by unscrewing the bottom half of the handle. No adjustments are needed to the receivers.
To power the microphone on press the button under the display. TODO Full buttonology of the handheld microphones.
¶ Use the XLR breakout box
The breakout box provides 4 audio inputs marked Red, Green, Blue and Yellow. The inputs are connected to the mixer as inputs 5-8 (XLR cables have a colored ring).
The standard use is to use inputs 5,6 (red, green) as aux audio output from the laptop via a Behringer unbalanced stero - 2x balanced mono adapter/attenuator.
The cable used to connect the breakout box to the case has to be STP, UTP will work as an antenna and pick up a lot of noise.
¶ Use the Panasonic S1 camera.
¶ Quick start
Turn the camera ON or OFF with a flip switch on the top of the camera near the right side.
If the camera doesn't turn on, plug it into power with the USB-C power supply and check the LCD on the top of the camera to check the status (power off for it to catch up to base battery charge).
¶ Mounting the lens
There are 2 lenses in the package
TODO lens detailed description - in summary one is wide angle-portrait, the other is tele. Use the portrait one for streaming inside xHain.
DON'T SWAP LENS IN A DUSTY ENVIRONMENT - if you can see or smell laquer, sawdust, gipsum dust, smoke or other particles - don't swap your lens there, move to a cleaner location.
- Prepare the lens by putting it on a table camera side up, untwist the cap, leave it on to cover the optics for now.
- Press the lens release button on the camera and untwist the cap.
- Minimise the time optics/camera insides are exposed and don't breathe inside the camera.
- Remove the camera cap, remove the lens cap, put the lens in (marker dot at 7 o'clock) and twist it into place (marker dot at 8 o'clock)
- Place the caps back into the camera case
¶ Focus
It's recommended to use manual focus (set it by rotating the ring above the main LCD to MF, or at least pressing the "AF ON" button. This is to avoid "focus pumping" during streaming, you can adjust focus with the ring on the lens.
¶ Quick settings
In short - don't alter them if you can. Below are the recommended quick settings that AVX uses for streaming.
TODO
ISO
color profile
resolution/fps
¶ Preview screen (Fotga)
TODO
Short desc: connect the camera to HDMI IN (there's a short HDMI cable in the camera case), connect the HDMI OUT from the display to the mixing desk. Connect 12V power by using the AA aku charger power supply.
The bonus of the screen besides showing exactly what's going on with the signal is an RGB/CMY vector display.
¶ Audio input block
TODO
For now slide into the hot shoe to switch camera audio to the XLR inputs on the block.
¶ Røde wireless mics
The Røde mics should be used only during recording not streaming for now since the audio input from HDMI doesn't go through the audio mixer in the AVX case if you use the audio input block.
After connecting the Audio input block via the flash hot shoe use the jack-XLR adapters to connect the Røde receivers (Receivers have a display) and power them on by holding the power button. The clip on the receiver also fits the lamp cold shoe placements (there's one on top of the audio block and one on the right side of the cage).
After you power on the related transmitter the receiver should show signal strength.
You can use the transmitter directly, cover it with a fluffy windbreaker or put it on the handle stick and cover it with windbreaker foam to make it look like a standard hand held microphone. You can also attach a lav mic via the input jack but the lav mic itself is worse quality than the built in capsule.
¶ remote Streaming
- Es gibt zwei Links: einer für Slides (muss Speaker selbst erstellen und Link uns schicken), und einer für Konferenz mit Herald (wird von uns erstellt und mit Speaker und Herald geteilt... siehe Links im Pad).
- Konferenz-Streaming Links über https://kevin.c3voc.de anlegen und Link mit Speaker sharen in dieser Form: https://kevin.c3voc.de/?roomid=xxxxxxx
- Funktioniert nur mit Chrome(!), da Firefox nur einen(!) rtc-Stream gebacken bekommt m(
Der Sound aus dem remote Stream (Jitsi oder whatever) ist erst dann im Lautstärkepegler in OBS zu sehen, wenn live gesendet wird (d.h. wenn Transition geklickt wurde und Stream im rechten Bild in OBS zu sehen ist). Der Sound ist aber NICHT über die Kopfhörer zu hören!!
- Workaround während Live-Stream: Zur Quali-Überprüfung mit separaten Laptop Live-Stream anhören.
- ugly Hack wenn noch nicht gesendet werden soll: Slider unter "Quick Transition" minimal hochziehen (siehe Foto oben) --> Bild und Sound sind im Stream dann nicht wirklich zu hören, aber immerhin wird dann der Sound im Lautstärkepegel sichtbar.
Bei remote Streaming Audio Filter "noise suppression" verwenden. Ist im aktuellen Setup voreingestellt. Falls es nicht gut klingt, zum deaktivieren, Rechtsklick auf Source > Filter > Auge-Symbol > an/aus.
