MB4 a miniature is
boundary microphone for multi-miking
applications such as teleconferencing,
distance learning, boardrooms,
courtrooms, d security applications. an
Double-sided sticky tape is provided for
attaching the unit under shelves, on walls,
etc.
Thanks to its supercardioid pickup pattern,
the MB4 greatly reduces ambient noise
and pickup of room reverberation. The
result is a clearer sound.
The MB4 has a 15-foot attached cable
leading to an XLR-type output connector
with built-in mic electronics. It is powered
by 12-48V phantom power, and is low-
impedance balanced.
Features
Tiny, inconspicuous.
Can be used without putting holes in
the table.
Clean, clear, natural sound.
Low-Z balanced mic-level output prevents
hu anm d high-frequency loss.

How to Paint e Microphoneth
1. Using a small screwdriver, pry open e sideon
of e base, then th the other side
2. Remove the foam liner.
3. Wearing a dust mask, spray-paint e grilleth
assembly. Be sure grille holes a re not clogged.
4. Allow completely dry.to
5. Make sure the D LE is properly aligned.

Installation
1.
In a table, typical placement for each
mic is
an arm s length from e user. Installth
one
microphone in front each person, oneof or
between every two people.
If e microphone will be used on ath
lectern,
install an open rface. Do notit on su
install a in
cavity recessed area as the frequency or
response d polar pattern will degraded.an be
2.
Orient the mic so the readable lable faces
the user (right-side-up).
3.
Plug a mic cable with a female 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.
