But I also use the Repeater with my acoustic guitar pickup output with no compression, and that's a very dynamic signal. I just try to make sure that my levels are set barely under the clipping point. That's critical for pushing down the noise floor (especially in a 16-bit system like this). Get those input levels hot! If you can't get a hot enough input level without lighting up the clip LED's, then you could try throwing a limiter ahead of the Repeater's inputs. That will tame the peaks and let you run a hotter input. Even a good limiter will mess with your attack transients though, so I'd only use this idea as a last resort. I think it's also a good idea to avoid using the instrument input on the front panel. I have a feeling the preamp on that circuit isn't super-high quality. Like Greg, I have a preamp (Roland VG-88) ahead of the Repeater, and I use the stereo line inputs on the back of the Repeater. One final tip -- I know this sounds dumb, but make sure the Line/Phono button on the back panel is in the out position, if you're using those line inputs. It's easy to accidentally press that button when you're groping around inside a rack case making cable connections. -- Mike Barrs
