MT830R
MINIATURE OMNIDIRECTIONAL CONDENSER MICROPHONE
• High intelligibility for lecturers, stage/TV performers and singers
• Provides excellent yet unobtrusive sound pickup
• Wide-range capability ensures clean, accurate reproduction
• Operates on phantom power only
The MT830R is designed to be worn as a lavalier or hidden in loose
clothing or in the hair. For use as a lavalier, attach the microphone
about six inches below the chin. Anticipate movements that may
cause the microphone to rub against or be covered by clothing, and
position the microphone to avoid it.
The MT830R is intended for use in professional applications where
remote power is available. It requires 9V to 52V DC phantom power,
which may be provided by a mixer or console, or by a separate,
in-line source such as the Audio-Technica AT8801 single-channel
or CP8506 four-channel phantom power supplies.
Output from the power module's XLRM-type connector is low
impedance (Lo-Z) balanced. The signal appears across Pins 2
and 3; Pin 1 is ground (shield). Output phase is "Pin 2 hot" –
positive acoustic pressure produces positive voltage at Pin 2.
To avoid phase cancellation and poor sound, all mic cables must be
wired consistently: Pin 1-to-Pin 1, etc.
Avoid leaving the microphone in the open sun or in areas where
temperatures exceed 110° F (43° C) for extended periods.
Extremely high humidity should also be avoided.
