The big truck in a small box is more than true. Recently I built some circuits and purchased some Baluns and now i have a professional OBU with high quality SVHS signal, tally and talkback with camera persons ( both ways director - operators). All this through a professional CAT 5/6 cable. Nobody would believe this was not a high end professional big TV production truck performance. I am still amazed and still not could not beleive what I have been loosing before purchasing the tricaster. Anybody interested and with the knowhow of building a circuit from may ask for the artworks which i have produced (my copyright). The circuits consist in : 1) Tally relay switching 2) preamp / amp for talkback 3) tally ptt circuit. I had perfect results from over 90 meters between videocamera & switching unit. Any body interested just ask.

I am very interested.

I also own a monster TriCaster Studio, 2 studio/field cameras (composite and svhs) and have been searching for the cabling solution. Please send any info, drawings or suggestions.

Thank you

One of the most important factor in multicamera video filming is the TALLY. Attached is the circuit for the six cameras. Description. Tricaster outputs 5v from tally 3.5 socket on front. This is voltage divide by a 5k preset to out put 0.8v which is sent through one pair of twisted wire to camera end. This small voltage is fed to a transistor switch which switches a relay sending 12v to a 12 array LEDs. Later on I post photos of the box which is attached to the camera IDE battery fitting. This box has attached to it a 6inc TFT monitor, talk-back and tally. Hope I will find the time to do photograph them this weekend

This circuit is common to all camera-persons and director. It consists of two parts - A) mic preamp to line level and B) headphones amp. It has a ptt which change over the function from listening to talking. This is a very important factor because it needs only a pair of twisted wire to send and receive.

This small pcb is fitted in a very small plastic case high enough to house exactly the pcb push to make switch. When the ptm switch is pressed, the illuminated led shows camera man is on talk mode. At the same time, it switches on the talkback circuit relay thus connecting videographer's mic to director's speaker. When the ptm switch is release, the videographer's circuit returns to listening mode. Note that no matter how many talkback/cameramen are in the system, as long as only one at a time uses this talk function, everyone can hear.

The setup can be mounted on a unit measuring 30in wide. My outdoor system takes four field cameras. The production unit is made up of: 15" rackmount lcd, Four 4" LCD rackmount unit, the tricaster studio, 4 Kramer DAs, Tally & talkback circuits. Thats all! Assembled and easy to use as ABC.

Thanks Robert. Infact I just wanted to show everybody that sharing is a most wonderful thing that broadens knowledge among people who already know and bring light to others who may not have had yet the opportunity to know. More than this, i am preparing a full pdf downloadable file with all the schematics, pcbs, photos and instructions to set up a multicamera mobile video production unit. I just hope that many more follow because everybit of information could be the missing jigsaw in somebody's else uncompleted puzzle.

Here is a very simple pcb which may prove very useful to save the lifetime of the tally sockets on the Tricaster front patching face.

What Baluns did you use for your set-up? I'm having a HECKUVA time finding any that will also support headset.

I too, had a few of these that didn't open.

I am using Muxlab 500034. It is SVHS, one audio and one composite video. The trick is in the circuits I designed. I am using the "video" crossed pair for TALLY and the "audio" crossed pair for TALKBACK. The talkback circuitry is designed so as to have as many as you want. By default all are in a listening state. By means of a ptt, a relay is activated and that circuit becomes talking. Every pcb at every end has a preamp and an amp.

The only trouble i have is that i cannot find suitable headsets. If any body can suggest anything will be mostly appreciated.

Note that Tricaster tally output is 5v and a voltage divider is required to feed 0.8 v ONLY through Balun - enough to biastransistor and switching relay to take the load of the tally lamps

This is another pcb showing which camera is onair as seen by people infront of lens. This can be turned on either through a paralell 0.8v from Balun or a 12 v feed from relay inside camera extended box. Should one use the 12v option, the transistors are bypassed and 12v fed directly to resistors' copper track.

This panel is Laser shaped on 6mm and 3mm sandwiched black perspex plates. The LEDs pop out of the black face and the camera number and logo are engraved (by laser) and filled with white paint. The finish is very professional and very attractive. I still have to take the photos.

I am preparing some photos and documentation how to build a complete 6 studio cameras production setup to share with all interested parties. I hope that i am not stamping on somebody's foot ! or that somebody might take commercial advantage from my postings !

Hello TIMECARE,

For what it's worth, you must be one of those rare individuals. There IS hope for us all.

I am looking forward to your solutions to TC integration. I started with covering live events so cabling for cameras, intercom and projection is important and I still do not have a good solution. I also want to have the studio option in the very near future.

Your input is priceless and if I can be of any help or assistance, please let me know.

One thing that crossed my mind when looking at the Tricaster panel for the first time was the fact that, often pluging and unplugging the tally 2.5mm jackplugs when using in different location, the sockets might get loose and suffer lot of wear and tear. So immediately I designed a simple pcb with 6 plugs mounted and wired to a 6 pin xlr at the other end. This pcb is always safely plugged in my Tricaster and when moving around in different locations I just plug the xlr into another panel which has fixed soldered wires to onward circuitry. Attached are some photos to explain visually.

The studio cameras back had to be attached somehow. The v-mount for the battery was ideal. So we put hands to it and in a couple of days we had the solution. Anybody interested in the freehand designs may ask for them privately.

Thank you for sharing your genius idea to fellow tricaster users! This will be a great help for us here in dubai since most of the projects live events.

Hi, I have been receiving many emails asking me whether i have quitted? Not at all, infact i am in the late stages of the mobile 6 cameras unit. Still a bit of work to do. Note that every 7" monitor has 40 LEDs running around which lights up to show specific camera on air. As one can see at the side is a panel which is nearly identical to the Tricaster. This gives facility to change Tricaster unit if it fails.

I have to hand it to you. This setup is impressive. Are you a production house or a school?

I had come up with a similar cat5/6 setup using mediatwist ethercon cables. However, with my setup, I was using a simple bnc to twisted pair balun for video and used a ClearCom intercom system. What was the reason for not using a preman'd intercom system and building an in-house setup?

Again, thank you very much for offering your materials for us. I love to see how other people do things.

I am a production house but my passion is making my own equipment whenever possible. I am really not happy with composite video signal. The least i can go to is SVHS which give optimum chroma for keying for example. Using SVHS demands 2 pairs of twisted wres in the CAT5e cable leaving the other two for TALLY and TALKBACK. When i finish the project and put it here, i will explain how efficient this sytem is. As regards talkback, i built my own circuitry which is tailor made for this setup. Apart from being cheaper, i can have full control on servicing/replacement when the need arises.
