For the US 120 V model:
A maximum of five SRM450v2s can be connected per 

15A service.

This allows each SRM450v2 to be safely operated at its 

maximum level.

When turning your system on, turn on the SRM450v2s 

last. This will stop any turn-on thumps and bangs from your 
source equipment being amplified.

When turning off your system, turn off the SRM450v2s 

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  

 

distribution system you know  
nothing about. You may even be faced 
with 2-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.

Don’t use an outlet if it is wired    
improperly! This is to protect yourself 
as well as your equipment.

Never remove the ground pin on the 
power cord of the SRM450v2 or any 
other component. This is very dangerous.
