A quick question for the Experienced Ones:

We are getting ready to spec a PA system for our church (newly renovated) and
I'm trying to get a handle on cable for mic and line runs. The runs from each
jack in the pulpit/choir/instrument area of the sanctuary go through dedicated
EMT to a junction box in a room behind this area and from there are run to the
sound booth in the back of the room through 2" EMT. My inclination is to run
single shielded pairs from each mic jack to a barrier block in the junction box
(its about 6" X 8") and then double-shielded multipair from there to the
mixer/breakout in the booth. Line level signals (to the remote amps in the
back, mostly) will go in a separate multipair but in the same 2" conduit. The
total distance from mixer to mic is slightly less than 100'. I would like to
keep capacitance to minimum, but is it worth it to spec something like Belden
9990 series, or should I settle for cheaper but higher capacitance? I should
also mention that we expect to use phantom power for most of the mikes, too.
Presently, there are 13 mic boxes, some of which could handle 2 jacks, but we
can't foresee using more than a handful of mics at any one time. The intended
usage will be primarily voice, both spoken and music; only rarely would we mic
an acoustic guitar or other quiet instrument through the system.

Thanks in advance for your suggestions. You may email them direct or post, as
you please.
