Thank you that you have opted for a LEWITT product. In this operating manual you will learn more about your LEWITT microphone, its handling
and its proper usage.
Music professionals know that it’s often the smallest details that make all the difference in vocal and instrumental recordings.
With our MTP series, we aim to exceed artists’ and audio engineers’ expectations of reproduction accuracy and isolation of the main sound
source. The new flagships among LEWITT's performance microphones - the MTP 840 DM and the 940 CM are true milestones of audio
technology.
All MTP microphones are professional-quality handheld dynamic and condenser performance microphones have been developed specifically
for the authentic, crystal-clear reproduction of vocals and are also well-suited for instrumental applications.
Customized frequency responses, a rugged construction, high gain before feedback and extremely low handling noise make all models of the
MTP series the perfect fit for any application, any performance and any setting.
LEWITT wishes you a lot of fun and success with this product!
Introduction

MTP 840 DM
With the dynamic performance microphone MTP 840 DM, LEWITT puts true studio performance onstage. Universally
usable thanks to switchable sensitivity and a multi-step high-pass filter, infinitely durable and optimally equipped for
punishing touring conditions without compromising on sound – this is what the MTP 840 DM stands for.
Excellent transient response, refined electronics and superior capsule design make the MTP 840 DM a unique tool for
onstage use. Innovative circuitry design and the highest-quality components make for exceptionally low self-noise and a
maximum of dynamic range when in active mode; the frequency curve, which is specially tailored for vocal recordings,
provides the ultimate in sound quality.
Numerous useful features make the MTP 840 DM incomparably versatile onstage and in the studio. A three-step highpass filter directly influences the proximity effect, allowing adaptation of the mic to an individual artist’s requirements.
The built-in three-position switchable amplifier, is specially adapted to the MTP 840’s components, allowing lossless
recording of even far-off sources. The LEDs on the MTP 840 DM, which can be turned off, make checking the mic’s
numerous settings a direct and easy matter even in the dark.
The new dynamic flagship MTP 840 DM transports the artist’s voice in a natural and powerful way, lending his or her
voice the necessary presence without falsifying its individual character. Consistent directionality across the entire
frequency spectrum makes for maximum protection against feedback, with the flexibly suspended capsule reducing
structure-borne noise to a minimum.

Connecting and Disconnecting the Microphone Cable
■
Before establishing connection, make sure that the microphone and the component
(e.g. amplifier) are switched off.
■
Lower the volume of the component (e.g. amplifier) before connecting the microphone.
■
Insert the connector into the microphone socket. Align the key on the connector with
the groove in the microphone, and then push the connector into the microphone until
it clicks.
■
To disconnect the cable from the microphone, pull the connector away from the
microphone while depressing the latch lock.
How to Use
■
Set the switch to ON when using the microphone, set it to OFF when it is not in use (only
applicable if your microphone has an ON/OFF switch).
■
When using the microphone, do not cover any part of the grille with your hand to ensure
best sound quality and accurate directivity characteristic.

Using the mic / Tech data
Hints
■
In order to prevent feedback (howling):
1.
Lower the volume.
.
2 Place the microphone so that it is not pointed
to the speaker and that there is a sufficient
distance between the microphone and the
speaker.
.
3 Do not cover the lower part of the grille with
your hand.
■
Positioning the microphone close to the
sound source causes the so-called proximity
effect (a boost in the low frequency response). This phenomenon can be used to create a
richer and warmer bass sound.

Cautions
Cautions
■
The capsule is a sensitive, high precision component. Make sure you do not drop it from high places and avoid strong mechanical stress and force.
■
To ensure high sensitivity and best sound reproduction of the microphone, avoid exposing it to moisture, dust or extreme temperatures.
■
Keep this product out of the reach of children.
■
Do not use force on the switch or cable of the microphone.
■
When disconnecting the microphone cable, grasp the connector and do not pull the cable.
■
Since the microphone consists of precise parts, do not attempt to modify or fix it. Contact qualified service personnel in case any service
is needed. Do not disassemble or modify the microphone for any reasons as this will void users warranty.
■
The casing of the microphone can be cleaned easily using a wet cloth, never use alcohol or another solvent for cleaning.
If necessary the foam wind stopper can be washed with soap water. Please wait till it is dry before using it again.
■
Also please refer to the owner’s manual of the component to be connected to the microphone.
