Installation
1. Typical placement for each mic is at arm’s
length from the user. Install one microphone in
front of each person, or one between every two
people.

If the microphone will be used on a lectern,
install it on an open surface. Do not install it in
a cavity or recessed area as the frequency re-
sponse and polar pattern will be degraded.

XLR-type connector into the power module.
Connect the other end of the cable to a phantom
power supply. Or if your mixer has phantom
power, connect the mic cable directly to a mic
input and turn on phantom power.

Architects’ and Engineers’ Specifi cations
The microphone shall be the Crown model MB-
4, MB-4E, or equivalent. The microphone shall
be a half-supercardioid electret condenser type.
The microphone shall use the principle of phase
coherency achieved by mounting a small-diam-
eter element very near a boundary. This elimi-
nates comb fi ltering in the audible spectrum.

The microphone will exhibit excellent off-axis
response and gain-before-feedback. The MB-
4 shall have a permanently attached 15-foot
(4.572-m) cable connected to an XLR-type con-
nector with built-in mic electronics. Powering
shall be by 12-48V phantom power. The MB-4E
shall have a permanently attached 15-foot
(4.572-m) cable without electronics/connector.
Its powering shall be by the Crown MB-100 or
MB-200 Interface.

At the output connector, nominal sensitivity shall

Service
If the microphone does not function properly,
check that it is aimed correctly and is connected
as described in this data sheet. If there is hum
or no signal, fi rst repair or replace the cable. For
the MB-4E only, check the slide-switch setting
in the MB-100 or MB-200 Interface. If the mic is
defective, return the microphone and the inter-
face in their original packaging to Crown Factory
Service, 1718 West Mishawaka Road, Elkhart,
IN 46517-9439. For further assistance or techni-
cal support call 800-342-6939.
