Ring out feedback frequencies before a room fills

Maintain and repair equipment that lives in a van

These are not adjacent or vaguely related. They are the specific topics the job uses on an ordinary day.

How people get in

Almost entirely apprenticeship — carry cables for someone good, then run your own shows.

What it pays

Per-event; experienced engineers in Phnom Penh earn well above local salaried averages.

Demand

Event-driven but consistently short of skilled operators.

Pay and pathway figures are indicative ranges gathered for this prototype, not verified labour-market data. A production version would source them from national statistics offices and employer partners.
