Look carefully and you'll probably see that it is +4 / -10, not + 48 / -10.  It is to match the input level of the DRPA to the output level of your source console.  Most pro units will be +4.

Are you sure you've written this correctly?  It should say +4/-10 and is referred to in the manual (Section 1,page 2) as "level selection".  The difference is often referred to as "professional" (+4) or "consumer" (-10).  It's there to facilitate matching gain stages in the signal chain.......I think.

James....

Maybe that's a bit clearer......if not authoritative.

Does this govern the operating level within the unit itself?

DR

The switch is akin to a volume control at the input stage, which allows the device to operate at optimum gain and headroom.
