It appears that they can be adjusted to line level inputs. I do not understand, though, how the rated sensitivity relates to volts out of a normal stereo preamp or CDP with a volume control. (Ok mixing consumer and pro audio, not sure if that's a good thing to do)Mackie states that -7.5 dBu-100 db SPL at one meter with input set in normal position. Also it can take up to + 4 dbU in normal position.
How does this relate to volts out of your normal consumer audio preamp level output? Say like 2 Volts into the Mackie for 105 db out or something like that.

0dBu=.775vThe formula for calculating decibels for voltage differences is 20*log(V1/V2)
You'll be wanting to use that 10 dB of attenuation.
How are these Mackies on violins? I read somewhere that the Dynaudio had smoother highs.

One thing they do we is massed strings--which is something, in my experience, a lot of speakers struggle with. A whole violin section playing in unison can sound really harsh on some speakers.
I'm not sure they're the last word in smoothness or magic, but they do a lot of things right and not much wrong. They're especially good at sorting out complex recordings and making sense of ambience. I've got a couple of distantly-miked piano recordings that never quite made sense to me, acoustically, before I got these speakers; with the Mackies, everything fell into place.
A very good value (by high-end audio terms at least). Nice speakers.
Thank you. I am considering these for a multi channel audio kit.
Consumer line level is typically -10dB.
In my experience, consumer stuff is HOTTER than pro stuff, much of the time, so it's a valid question, which is not what +4dB (pro) vs -10dB (consumer) would suggest. Unless I'm fundamentally misunderstanding what those numbers mean.As an example, a while ago I tried to use an M-Audio interface with input from the output of a consumer CD player. It was WAY too hot; I had to put a mixer in the middle (only thing I had on hand that would attenuate the output) to make it work. I talked to the folks at the store where I bought the M-Audio unit (yeah, it's not truly "pro" gear, but the specs indicate pro levels, if memory serves, and it's got quarter-inch inputs, not RCAs). He said the same thing: that he finds (eg) CD player outputs to be a lot hotter than typical pro line-level stuff.

CD audio out is 2 Volts that higher than the usual pro level. The consumer line in/out (Tape Loop) is traditionally at the -10dBU level.
