Loose Connections
As you have leafed through this magazine, bet every one of you has stopped and marvelled at some amazing new
technology you wish you had.
Every day tools appear that make our lives easier and assist us in producing super work.
Now. Allow me to both, vent and preach on one aspect that I was tearing my hair out on when I started and sadly
continue to be pulling my hair out even today.
‘Connections’. Not the connections that got you the job. The connections through which all our signals and electricity
flow, that enable the lighting rig to actually produce what you programmed. Disclaimer. My issues are usually with the
live Lighting Rigs. But I have seen enough sound guys and video dudes expressing the same frustration I feel. So here
goes...
It’s usually not the quality of the equipment. Hey ! You get what you pay for. Usually - The more money you spend - the
quicker the connection process AND the longer lasting. BUT, not always.
Let’s work through the issues. Just to figure out the weak links.
We are setting up very sensitive networks in some inhospitable environments. It’s Hot. Its dusty and there is never
enough time. Usually the cabling is laid down by the junior most and least experienced guys on the team. I think
half our problems begin and end there.
Let’s look at equipment. Our country does not have any standard mains cable connectors. So even the most sensitive
equipment is powered by a mains cable screwed into a metal box. 1917’s systems powering 2017’s latest technologies.
Think about it. If it works - why tinker with it. The Answer is - ‘Yes it does work - Until it does not! No heads up.
No fail safe.
Now follow that mains cable down the line as it branches out and is distributed around the network. On dusty ground, wet
ground, carpeted ballrooms, tiled backstage arenas. Rarely will you find a connector. Just some wires twisted together.
Rarer still is a box that meters or monitors the power supply. I have definitely seen more Deity’s pictures than Amp
meters in a temporary electrical grid. But Hey - It works.
Next Step. From Dimmer racks to the actual light fitting. Improving. Now we definitely see a lot of connectors. Which is
why fault finding is usually restricted to faulty fixtures. Great!
Then, perhaps most critical - the signal cable. Here all of us worship at the altar of the mighty XLR God. Most used and
perhaps least understood of all connectors. Perhaps that is by its inclusive design. It’s used for everything from lead
singers mikes to guitar amps, to dmx cables to smoke machines and intercoms. That’s the good part. The problems arise
when our guys on the ground think they are infallible and interchangeable. In my opinion the graveyard of all networks.
Rarely have I been through a show where everything works the First time. No Time for fault finding - chuck back in the
box and replace. Where it may probably lie...
Now the Cat 6 cable has appeared. Designed to be used in Air-conditioned spaces. Its multi cores tightly wound to make as
small an imprint as possible. Suited for a network Box. Very badly suited for a concert arena. I am not aware of any
effort to make a sturdier connector.
Coming back to the first point. All connections usually set up by a junior member and usually unmarked. So fault finding
is always going to be tough.
In your estimate - How many man hours have you lost in figuring your way around the network? And usually at crisis times
when it may have impacted your ability to deliver everything that was designed around the show.
Is there a fix ? I know of only one. Like in a diet (that I find impossible to follow) the only way is to - 1. Plan 2.
Execute as per plan 3. Pray
Now let’s think Ideal World.
It starts with the purchase manager, who generously gives you budgets to buy good quality cables and connectors. Then
given to a super technician who will tin and securely solder each connector.
Each XLR colour coded as per use. Black for DMX lines. Blue for smoke machines. Orange for intercoms. All DMX networks
TERMINATED adequately. A special box on each show into which EVERY faulty cable is deposited and isolated.
On the Mains side - Cee Form Connectors all around. To a power box that measures all capacities and lifts all earth
loops. Where cables cross open ground - Rubber cable Trays
On the Lighting Grid - only identical fixtures on each network connected up to a Good quality Splitters. All fed down
a protected and double lined cable down to the Desk. Where a merger will feed two boards.
On a Cat 6 grid. At least a 4 cabled armoured cable fed into a hold box that clamps onto your unit and holds the Cat
6 firmly in place.
And every connector marked - where it comes from and where it feeds into.
Think about how easy this is. How much longer will set up take? Maybe half hour. Now think about the stress you will
eliminate. Worth It Na ?
Oh. The most important - a dedicated work bench with gleaming tools, solder irons and test boxes devoted to cable testing
and repair. Cables tested every 10 shows max.
That’s my Dream of ‘Achhe Din’.
