Cables connections inside / outside ?

PostSat May 21, 2022 2:29 pm

what is the best way to link OBV to stage ?

A hatch, keep door open, through-panel mounting connectors :?:

With time, do you regret or validate your choice ?

Do what the big boys have been doing since the invention of outside broadcast or you'll regret it.

  • Equipment goes inside, away from the water, dust, dirt, mud, wind, sand and all the other stuff that ruins delicate equipment.*
  • Cables plug in outside on a tailboard (doesn't need to be at the tail of the vehicle). Make sure you have the ability to replace connectors when they get damaged by exposure - avoid premade panels which require you to dismantle half the vehicle to change a single BNC.
  • Consider cost-effective monitoring of audio / video / talkback from your tailboard - don't spend loads on it, it's only there to give you confidence you've plugged up correctly (or to talk to someone indoors while you adjust the patch) - expect to replace this stuff on a regular basis
  • Make sure you can close the doors - your operators won't like sitting for hours in a furnace in the summer or a freezer in the winter, and certainly won't appreciate a damp draft coming in from a cable hatch by their foot. Uncomfortable operators = poor quality output.**
  • Water gets everywhere - it doesn't matter how good you design your hatches, water will still get in. Design appropriately
  • Never rely on the connector strain relief - someone will trip over your cable and yank it, or someone will try and pull it out without unplugging it first - use rope to strain relieve the cables before you plug them in to protect both the cable connectors and the tailboard connectors.
  • Label everything CLEARLY - it's no fun trying to plug something in to SD1 written in 4pt Comic Sans on a cold winter night when there's a whole bunch of adjacent connectors just labelled SDI


* this is why the studio fibre converters, with their front panel fibre connections and no option to move them to the back were greeted with despair by many professionals - there's no way they are suitable for installing in a tailboard, and the front panel connector makes no sense in a rack location either.
** sure, your camera ops on the roof in the snow aren't able to turn the heating up, but they can dress appropriately and you can make adjustments to their environment - shelter + portable heating/cooling where possible. But proper camera's are designed to be operated in gloves, a thick winter coat and thermals - vision mixer panels and sound desks are not!

While I don't have an OBV, I do a large multi-day, multi-band concert every year. We are located inside a Job Trailer for the 4 day event. There are no pass throughs (there technically is for power but it's not large enough for everything we send out (10 camera lines, LED wall line, 2 cat5, power, com, and a couple lines of audio).

Here's what I do: I pop the screen out one window. I gaff tape a garbage bag around the window leaving the bottom completely open. This has to be done when the outside is dry.

In the 20 years I have been doing this festival, I have never had a drop of water get into the window and the gaff holds the entire time (sun helps to back it in...lol).

I realize this is not exactly what you are asking, but thought I would put it out there for someone that can't install a patch panel.

It's right also for client side. A concert hall builded last year, havn't external cable entry !

I saw a little screen but I can't identify product. Any proposal for such monitoring device ?

I think that particular unit is made by TSL:

Wohler also makes similar units:

And Blackmagic has their own Audio Monitor 12G as well:
