Roll-off (MT830a)
- Clip-on lavalier mic provides crisp, full-sounding voice pickup
- Also excels as an instrument mic, especially for pickup of acoustic
guitar with included AT8444 instrument adapter
- Excellent gain before feedback and suppression of background
noise
- Switchable low-frequency roll-off
- Operates on battery or phantom power
For use as a lavalier, attach the microphone about 150mm 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 AT831b requires 11-52V DC phantom power, or a 1.5V AA
battery for operation. A battery need not be in place for phantom
power operation.
Battery installation: Remove the cap from the top of the power
module. Insert a fresh 1.5V AA battery (“+ end toward the cap
release button), then reassemble the power module. Alkaline
batteries are recommended for longest life. Remove the battery
during long-term storage.
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.
An integral 80 Hz high-pass filter provides easy switching from a
flat frequency response to a low-end roll-off. The roll-off position
reduces the microphone’s sensitivity to popping in close vocal use.
It also reduces the pickup of low-frequency ambient noise (such
as traffic, air-handling systems, etc.), room reverberation and
mechanically coupled vibrations..
The microphone is RoHS compliantfree from all substances
specied in the EU directive on hazardous substances.
Avoid leaving the microphone in the open sun or in areas where
temperatures exceed 43°C for extended periods. Extremely high
humidity should also be avoided.
