Yesterday, as planned, we did another round of testing of our Traditional Music System.
We had 4/5 members of the wonderful bluegrass group Bow Junction (http://www.bowjunction.com) here at our Live Music Listening Room at the Bose Reservoir Building. This is a nightclub/small-auditorium sized performance space we use as our live music laboratory.
Bow Junction purchased three Cylindrical Radiator(r) speakers more than a year ago now and use them in a variety of situations. Bow Junction (minus upright bass player who was ill):
Russ Aufertin - Guitar
Kathy Barnes - Fiddle
Lina Magoon - Mandolin
Pete Ocom - Banjo
We were also joined by banjo player extrordinaire Rich Stillman, and guitar great Geoff Bartley. Rich has been helping us learn about the needs of traditional music players. Geoff, who runs a famous traditional music weekly jam here in the Boston area, is also Tom Paxton's playing mate, and designed the new Tom Paxton Signature Model Guitar. (Tom Paxton will receive the highest honor from The Folk Alliance in January -- The Lifetime Achievement Award -- HOORAY TOM.)
Our goal was to explore microphone spacing, player comfort, and microphone type in our work over the course of about three hours. Steve, Brendan, and I, all of the Bose Live Music Technology Group were there to help and listen.
In the course of the next several posts, I'll describe in pictures and words what we found from my perspective. I'm sure that some of the other participants will add their voices to this thread, and as always, we welcome yours.
Here's the Traditional Music System setup with the notes added.
Here's a link to the Sketch in case you want to review it, edit it, printi it, or share it with others.

Green numbers are for general notes about the Sketch and connections to non-Bose gear.
Quoting Ken-at-Bose from The Sketcher
quote:Spacing of mics should be about 30 inches (75 cm).
Microphones successfully tested are: Shure KSM44â€™s on cardioid pattern (there is good reason to believe they will also work well on figure eight pattern but this has notbeen tested); Audio Technica AT4033, and AKG 3000-B. All can be purchased at good prices at Musician's Friend.
Microphones should be "toed in" by about 10-15 degrees: in other words,should be turned so that their diaphram is pointed a little in towards the center rather than straight back.
Cylindrical Radiator(r) speakers can be "toed in" too. Point them in toward the center of the audience 10-15 degrees. This will provide a little more foldback to the players so they can hear their mix a little.
There is reason to feel that the upright bass might be better off plugged directly (via pickup) into system 1 or 2 rather than go through the mics. The reason is that it is often difficult for the bass to be "choreographed" well enough relative to the mics given its size. This has not been tested and so remains a question mark.
