Crown’s Quarterly Microphone Newsletter             Fall 2002            Bruce Bartlett, Editor             

 

In the July, 2002 issue of Elec-
tronic Musician, in the  article 
"Build a Personal Studio on Any 
Budget," the Crown CM-700 
cardioid condenser microphone 
was chosen to be part of three 
proposed "dream" studios.

Those studios were the $6000 
portable digital studio, the 
$15,000 Windows studio, and 
the $30,000 studio without com-
puter.

Mics are commonly used in con-
ference rooms for recording, 
teleconferencing, and sound 
reinforcement.  Many customers 
do not want to see the micro-
phones, so they specify ceiling-
mounted mics. In this case, 
appearance is a higher value 
than sonic performance.

Ceiling-mounted mics are feasi-
ble for audio recording, but only 

if the room acoustics are very 
dead.  Otherwise the mics pick 
up a lot of room reverb which 
muddies the sound.  Also, ceil-
ing mics work poorly for sound 
reinforcement. The distance 
from mic to source is just too 
great to allow much gain-before-
feedback. If at all possible, use 
table-mounted mics for best 
gain and clearest sound.

If you want to use an omni ceil-
ing-mounted mic, try a Crown 
PZM-11 in an electrical box. It 
costs little, and its high frequen-
cies are boosted for extra clarity.

For less reverb pickup, try four 
Crown MB-4 mics on the ceiling 
angled 90 degrees from each 
other.  Feed the four XLR out-
puts to an automatic mixer.  
Recommended settings on the 
mixer are: release time very 
long, and automatic gain control 
on. Again, this setup is not rec-
ommended for sound reinforce-
ment. 

Although the CM-700 was not 
designed to be a stage-vocal 
mic, it can be made to work 
quite well in that application. 
Singer/guitarist Bob Lichty used 
the CM-700 for vocal pickup at a 
recent concert. He had this to 
say about its use:

"I used the double low-cut filter 
on the CM-700 for vocals. For 
guitar, I left the low-cut switch 
flat and rolled out a bit of the 
lows at the board. I learned how 
to "mask" my p's and t's with 
singing technique, so they are 
rarely an issue for me. I love the 
sound of the 700, and even my 
wife can't believe how different I 
sound 'all miked up' versus just 
singing at home in the bed-
room."
