Do rack mount synth/modules output at +4db or -10db?

[Jedman]

Just trying to decide on something, and I was wondering if anyone knows if rackmount synthesizer modules output at +4db or -10db?

Thanks,
Jed

Most of nowdays use +4dB. Only an oooold ones used -10dB.

What about an Alesis QSR or S4 plus (the rack versions)?
I'm looking for a good piano sound - that's why I'm thinking these two oldies but goodies...
