Cable wrap, connectors, repair

Specific equipment ages out. Cable discipline never does. The crew that handles cable like it is expensive is the crew that gets called back.

6 lessons · 3 paper · 3 the room

Every lesson is read, then do, then check.

The check carries its answer underneath it. Look only after you have tried — the attempt is what teaches, not the answer.

Lesson 1 of 6The room · Needs real equipment · the Depot

Over-under, until your hands do it without you

Read
A cable has a natural resting shape. Wrapping it in a plain loop fights that shape and puts a twist in it every single turn — which is why badly wrapped cable goes stiff, kinks, and eventually breaks at the connector. Over-under alternates the direction of each loop so the twists cancel. A correctly coiled cable also throws clean across a stage and lands flat, which is the real reason professionals do it: it is faster, not just tidier.
Do
Coil the same cable ten times. The first few will feel wrong. Keep going until you can do it without watching your hands, then throw it out across the floor and watch whether it lands flat or in a tangle — the throw is the test, not the coil.
Check

Why does a plain loop damage a cable when over-under does not?

Lesson 2 of 6Paper · Needs nothing but a pen

The five connectors you will actually meet

Read
XLR — three pins, balanced, microphones and most signal between equipment. TS — one tip, one sleeve, unbalanced: guitar leads, and short runs only. TRS — looks like TS with an extra ring; it is either balanced or carrying two channels, and you have to know which. speakON — a twist-lock connector for the high-power run between amplifier and speaker, deliberately built so it cannot be confused with signal. IEC — mains power into the back of equipment. Being able to name these on sight is the difference between being handed a job and being handed a broom.
Do
Lay all five in a row. Name each one without looking, then say what it carries and over what distance you would trust it. Then find the one that physically cannot be plugged into the wrong thing and work out why the industry made it that way.
Check

Someone hands you a TRS and a TS of the same size. How do you tell them apart, and why does it matter?

Lesson 3 of 6Paper · Needs nothing but a pen

Balanced or unbalanced, and the distance where it stops being an opinion

Read
Over three feet, nobody can hear the difference. Over fifty, the unbalanced run is a radio aerial — it will pick up lighting dimmers, mobile phones and the building's own wiring, and it will do it in the quiet part of the set. The working rule is simple: anything leaving the immediate area goes balanced. If a source is unbalanced and has to travel — a keyboard, a laptop, a bass — you put it through a direct box right there at the source and send it balanced from that point on.
Do
Write down every unbalanced source you can think of on a typical stage. Beside each one, write where you would put the direct box — at the instrument, or at the desk — and why that choice is not arbitrary.
Check

A keyboard is 80 feet from the desk. Where does the direct box go?

Lesson 4 of 6The room · Needs real equipment · the Depot

Finding the dead one

Read
Cables fail far more often than equipment does, and they fail intermittently long before they fail completely — which is worse, because an intermittent fault gets blamed on everything else in the room. The failure is almost always at a connector, where the cable has been bent, stood on and pulled. A cable tester gives you a yes or no in two seconds. Without one, you substitute a known-good cable — and the phrase known-good is doing real work there.
Do
Test a box of cables and sort them into good and dead. For each dead one, flex it slowly near each end and watch the tester: find whether the fault is in the middle or at a connector. Mark the dead ones so nobody else loses twenty minutes to them.
Check

A channel crackles when the singer moves but works when they stand still. Where is the fault, almost certainly?

Lesson 5 of 6The room · Needs real equipment · the Depot

Open it, solder it, prove it works

Read
This is the lesson that separates a helper from a technician. An XLR comes apart with one screw or none. Inside are three solder points, numbered. You will find a wire that has pulled off its pin, or a strand of shield bridging two pins. You reheat the joint, remake it, reassemble, and then — the part people skip — you test it and label it. An unproven repair is worse than a known failure, because it goes back in the box and lies to the next person.
Do
Open a dead XLR. Find the fault and say out loud what it is before you fix it. Resolder it, reassemble it, test it, and put your initials and the date on it. Then do a second one unsupervised.
Check

You have resoldered a cable and it looks right. Is the job finished?

Why this is the module that gets you hired

Read
Nobody is hired off their opinion about microphones. They are hired because the crew chief watched them coil cable correctly, label a run, and leave a case tidier than they found it. Cable discipline is visible from across a room and it is the first thing an experienced person looks for, because it predicts everything else. This is also the cheapest skill in the trade to practice — it needs one cable and your hands.
Do
Think of a show, a service or an event you have been to. Write down three things you could have done there, with no technical knowledge at all, that the crew would have noticed and valued. Be specific. 'Help out' does not count.
Check

What does a crew chief learn about you from watching you coil one cable?

For whoever is teaching it

Instructor notes

  1. ⛔ This is one of the two things the curriculum names as what makes a student employable — the other is signal flow. It is never optional, never compressed, and never the module you drop when a session runs short.
  2. Four of six lessons need real cable, so this module is Depot-weighted. Plan it for a session where you have a box of cable and a tester, and bring dead cables deliberately — do not hope for them.
  3. Over-under cannot be learned from a slide. Expect to physically move a student's hands. Ten repetitions minimum, and the throw is the test.
  4. A soldering iron needs supervision and ventilation. Confirm both before the session rather than on the night.
  5. The labeling habit is the hardest to instill and the most valuable. Mark every repair in front of them until they do it unprompted.
  6. Students who already play in bands often arrive with confident bad habits here. Correct the coil without making it personal — most were taught wrong by someone they liked.
  7. If equipment is short, the connector-identification and balanced-run lessons still work on paper and can be moved out of the Depot session.

Slide running order

What goes on the screen.

  1. One cable, coiled well and coiled badly, side by side
  2. Over-under in four frames
  3. The five connectors, photographed at actual size
  4. Two wires over 100 feet: balanced quiet, unbalanced humming
  5. An unbalanced source and two DI positions — one right, one pointless
  6. Inside an XLR: three solder points, numbered
  7. A labeled repair versus an unlabelled one — which comes back to bite

If you want more

Extra credit

  1. Coil every cable in your house over-under: phone chargers, extension leads, headphones. The habit transfers and so does the muscle memory.
  2. Price a cable tester and a basic soldering iron. Knowing what the tools cost is part of knowing the trade.
  3. Find out what your nearest venue or church does with dead cables. Many throw them away. Ask whether you can have them to practice on — this is also how people get known.
