Nominal output level - JBL LSR305

[firewired]

I just purchased JBL LSR305 studio monitors for my MBox 2 Pro gear. In the Manual is says:

"3-Series speakers are equipped with an INPUT SENSITIVITY SWITCH. The switch is set to the -10 dBV setting when it ships from our factory. This setting will be best for many applications. However, you can set the switch
to the +4 dBu setting:
When connecting 3 Series speakers to professional equipment with +4 dBu nominal output level, set the INPUT SENSITIVITY SWITCH to the +4 dBu setting. To determine the nominal output level of the connected equipment, consult the documentation supplied with the connected equipment.

I can't find anything about nominal output level for the MBox 2 Pro. Where can I find this?

just set it to +4 and move on
