A sound technician should have a good variety of Radio Shack audio
connector adapters to convert between 1/8", RCA, 1/4", XLR,
male/female, and mono/stereo connectors
A variety of short (3') cables are needed to interface between
mixer and FM receivers, tape deck, CD, equalizer, effects
processor, and amplifiers. Most use 1/4" to 1/4" cords, but some
use RCA, XLR, or 1/8"

Patience and a cool temper
If your total sound system does not require more than 15
amps, then connect EVERYTHING to one outlet to reduce the
possibility of ground hum.
You need several AC power ground-lift adapters (3-prong to
2-prong adapters), a few multi-outlet adapters, several
multi-outlet power strips with surge protectors, and a variety of
3-conductor extension cords (of different lengths).
You should have a 3-prong AC power tester and always test an
AC power outlet before you use it (prevents equipment damage due
to faulty wiring).
If you do get a ground hum, use your power tester to test the
power feed to every unit first, then try a ground lift adapter on
each unit of the system, one at a time, until you find the source
of the hum.
An intercom system may be helpful if it is necessary for
the Sound Technician to talk to Stage Crew or Lighting
A projection system may be useful if song words are to be
displayed for the audience

Engrave a permanent identity name or number on all expensive
equipment (to identify it in case of theft).
