Mackie SRM450 V2 User Manual page 13

For the US 10 V model:
A maximum of five SRM450 vs can be connected per
15A service.
This allows each SRM450 v to be safely operated at its
maximum level.
When turning your system on, turn on the SRM450 vs
last. This will stop any turn-on thumps and bangs from your
source equipment being amplified.
When turning off your system, turn off the SRM450 vs
first. This will prevent any turn-off thumps and bangs from
your source equipment being amplified.
When setting up for a show, often you
are plugging into an AC power distribu-
tion system you know nothing about.
You may even be faced with -wire
outlets that are missing the third safety
ground pin. It's a good idea to have a three-wire AC outlet
tester in your toolbox so you can check the outlets yourself
to make sure they are wired correctly. These testers will tell
you if the polarity of the hot and neutral wires is reversed
and if the safety ground is disconnected.

SRM450 2: AC CONNECTIONS
v
Don't use an outlet if it is wired improp-
erly! This is to protect yourself as well
as your equipment.
Never remove the ground pin on the
power cord of the SRM450 v or any
other component. This is very dangerous.
