Audio-technica MB 2000L microphone User manual

Below you will find brief information for microphone MB2000L. The MB2000L is a cardioid condenser microphone with a wide frequency response, making it suitable for a wide variety of applications, from close-up vocals and instruments to live sound reinforcement. The microphone features a high-output neodymium magnet, a special internal shock mount system, and a MagnaLock™ on/off switch for silent operation. The MB2000L is also equipped with a multi-stage windscreen to reduce wind noise and popping, and a foam-lined carrying case to protect the microphone during transport and storage.

Neodymium Dynamic
Cardioid Microphone
Description
The MB2000L is a wide-range moving coil dynamic mic with
a cardioid pickup pattern. It features a high-output neodymium
magnet for maximum performance with all equipment.
The MB2000L is designed specifically for close-up vocal and
instrumental use. Crisp high-frequency response and extended
low-frequency response make this microphone an ideal choice
for lifelike instrument pickup. A special internal shock mount
system minimizes handling and case noise. The microphone
also features the MagnaLock&quot;&quot; on/off switch for silent operation.
The switch may be locked in the “on” position to prevent acci-
dental turn-off during use. &copy;
The cardioid pickup pattern of the MB200OL is useful in reduc-
‘ing unwanted background noise and controlling feedback,
especially when used extremely close. Miking instruments or
vocalists at very close range also effectively reduces “leakage”
from one performer to the next. Low-frequency noise is also
reduced by a low-frequency roll-off of sounds more than one
foot distant from the microphone.
The high-output neodymium design and low-mass diaphragm
and voice coil assure excellent signal-to-noise ratios with
microphone mixers, tape recorders, and other electronic inputs.
The MB2000L is capable of undistorted output even in very
intense sound fields.
Enclosed in a rugged die-cast housing, the MB2000OL features
a special, baked-on “Midnight Blues” finish. In addition to
being attractive and comfortable to hold, this special finish
further reduces handling noise and increases durability.
A multi-stage windscreen reduces wind noise and “popping”
when performers work extremely close. The included micro-
phone clamp permits mounting on any microphone stand with
5/&quot;-27 threads. &Agrave; foam-lined carrying case is provided to protect
the microphone during transport and storage.
_Operation and Maintenance
—]—]—] a.
Output of the MB2000L is low impedance balanced. The profes-
sional 3-pin microphone output connector mates with XLRF-type
cable connectors. The balanced signal appears across Pins 2
and 3, while the ground (shield) connection is Pin 1. Output is
phased so that positive acoustic pressure produces positive
voltage at Pin 2 in accordance with industry convention.
The MB2000L utilizes a MagnaLock on/off switch. This specially-
designed switch operates silently and may be locked in the “on”
position to prevent accidental turn-off during use. To lock, slide
the switch up into the “on” position (Fig. 1a). Using a small flat-
head screwdriver, rotate the small screw in the center of the
switch 90 degrees (1/4 turn) counter-clockwise (Fig. 1b). Never
force the screw. When the screw slot position is horizontal
(“across” the microphone body), the switch is locked. To unlock
the switch, turn the screw 90 degrees clockwise until the screw
slot position is again vertical (in line with the microphone body).
Never try to turn the switch more than 90 degrees or /+ rotation.
The switch may only be locked in the “on” position. Do not try
to turn the screw when the switch is in the “off” position.

While every effort has been made to provide an extremely
rugged microphone, reasonable care should be taken to avoid
abuse. The microphone can withstand a wide range of tempera-
tures and humidity without damage. Take care to keep foreign
particles from entering the windscreen. If the microphone is
exposed to an environment with small iron or steel filings
(on a workbench, for example) these fine metal particles can
accumulate on the diaphragm, reducing low-frequency response.
Excessive accumulation of dirt on the windscreen will reduce
high-frequency response.
