I should add to my personal endorsement of the Kawai PR1 system that you want your castors tight, legs tight, lyre tight and trapwork quiet when miking under the piano. The benefits are: greatly reduced/eliminated damper swoosh reduced/eliminated hammer percussive sound reduced/eliminated string noise in the ultra high partials. much less room interference and good noise isolation The Kawai mikes are mounted to beams with velcro underneath the bridges. The treble one close and the bass one further down. You should be able to do this with good unidirectional mikes. But you will have to replicate the EQ, panning etc on your equipment rather than dialing purpose designed ones up on the PR1. Of-course Pros may wish to avoid those and have more control... (or headache depending on you're point of view). Good luck, Andrew Anderson
