Low Level inputs (0dB and +12dB) on a subwoofer (1 Viewer)

[Willem Vos]

Hi, question:

why does my sub (a REL Q150e) have two different low level inputs? One is marked 0dB and the other 12dB.

The manual doesn't even attempt to explain this, so I opted for the 0dB (it sounded safer)

Is this really the prefered option, however?

Since I can adjust the subwoofer output using my receiver would it be better to hook it up to the +12dB input so the amp in the sub doesn't have to "work" as hard (something I read on another forum)

Any suggestions?

I think the *+12* input is if your procesor isn't putting out enough voltage via it's subwoofer preout to drive the subwoofer to proper levels. If you can calibrate properly using the *0* input...that should be fine.
