QUESTIONS WITH 100% CORRECT
ANSWERS
Speakon (NL2, NL4, NL8) - correct answer 2, 4 or 8 conductors. Used to connect
Amplifiers to speakers. NL4/NL8 often have NL2 breakouts at one end. Sound
Ethernet - correct answer 8 conductors. There are several ethernet standards that use
the same connector: Cat5e, and Cat6 are usually used in our industry. Sometimes
found with a locking "Ethercon" connector that looks like a XLR barrel. Some
applications required a shielded version of this type of cable. General, A/V, Data
Edison - correct answer 3 Conductor "normal" extension cord. Generally, non-
grounded is not suitable for our use. Depending on wire gauge and jacket, suitable for
up to 15-amp service. Can also be referred to as a Parallel Bar Ground (PBG). Power
IEC Power - correct answer Many devices requiring standard 120V "wall power" use
this IEC Plug, usually with an Edison plug on one end, and a IEC socket to attach to the
device. Sometimes called a "Computer cable" or a D-Plug.Power
3-Pin XLR - correct answer Standard balanced audio cable. Used for sound sources to
destinations, like microphones to a mixer.*in some cases, specially made 3-pin XLR
cables are used as DMX cables. Audio
4-Pin XLR - correct answer Used for powering and controlling lighting accessories
like gobo rotators and color scrollers. Lighting, data
5-Pin XLR (DMX) - correct answer Used for powering and controlling lighting
accessories like gobo rotators and color scrollers. Lighting, Data
TS/TRS (1/4-inch plugs) - correct answer Tip-Sleeve: 2 conductors. Standard un-
balanced audio connector-like a normal guitar or instrument cable.Tip-Ring-Sleeve:
Same form factor, but with an extra conductor for either a balanced signal, or an

QUESTIONS WITH 100% CORRECT
ANSWERS
Fiber Optic - correct answer Used for high-speed data signals like sound, video, or

because the glass core of the cable is extremely fragile and can easily break if
crushed or bent. General, A/V
Foam Ear Inserts (Ear Plugs) - correct answer These protect from damaging levels of
noise. Anything louder than city traffic (85+ dB) can cause permanent hearing damage
after 2 hours of exposure.
Hard Hat - correct answer Most hard hats are designed only to protect from falling
hazards from above. By law, employers must provide appropriate PPE to workers, if
you bring your own, it must at minimum meet the current ANSI Z89.1 standard.
Climbing helmets are acceptable if they meet the same ANSI standard.
Safety glasses - correct answer To protect from projectiles or dust hitting your eyes.
Gloves (Insulating rubber) - correct answer In some cases when working with high
voltage, gloves with an electrical insulation rating may be required.
Gloves (welding) - correct answer When welding, sturdy leather gloves are required to
shield your hands and for arms from sparks and hot slag.
Welding Leathers - correct answer In absence of a strong and flame-resistant coat,
welding sleeves can be used to protect your arms and upper torso from welding
sparks and hot slag.
Welding helmet - correct answer Welding helmets are required for welding work due
to the massive amount of UV emitted by an open arc. Without covering, your skin and
eyes can be burned by an arc flash in a matter of seconds.

QUESTIONS WITH 100% CORRECT
ANSWERS
Work gloves - correct answer These protect from burns due to hot lighting
instruments or abrasions from handling rough materials. Some people prefer
fingerless gloves for dexterity.
Full Body Harness - correct answer Whenever someone is working at a height above 4
feet, by law an employer must provide a fall protection or prevention system. The
choice of system should be evaluated by trained qualified person. Usually, if working at
height in this industry you will need to be able to don a full body fall arrest harness,
and use a shock absorbing lanyard to stay tied off 100% of the time.
Respirator - correct answer Various types of masks protect you from exposure to
dust, airborne biohazards, fumes, or chemical in the air depending on the type of filter
used.These types of respirators have vents that allow air to expel without passing back
through the filter and are not considered acceptable to prevent the spread of
respiratory illnesses.
Dust Mask - correct answer A NIOSH approved dust mask, like an N95, is acceptable
for protection from air-born particles and droplets.If you are using an N95 or any type
of mask to prevent the spread of respiratory illness, it must not feature a valve that
allows exhaled air to bypass the filter.
Boots (Safety Toe) - correct answer These protect your foot from piercing damage by
objects on the floor as well as from crushing damage. Many venues Local 15 workers
are employed in require workers to wear ANSI Protective Toe compliant shoes. The
protective toe can be either steel or a composite material.
Tool Belt* - correct answer The tool belt you choose should be capable of carrying all
required tools. You don't need a stealthy one specifically designed for theater—you
should only need it for building, assembling, and loading shows in and out of a venue.
You may find it worthwhile to also keep a smaller tool holder to just keep the
essentials for a given job on you if you find you don't need the entire required tool list
once you've started work.
