ND68

▪ Excellent acoustic isolation with deep lows and top-

end punctuation

▪ Large diaphragm dynamic capsule creates a rich and

detailed frequency response

▪ Extremely high SPL handling

▪ Humbucking coil guards against line hum

▪ Memraflex grille resists denting

The Electro-Voice ND68 is a robust, high-performance
dynamic supercardioid kick drum and low frequency
instrument microphone.
The ND68 supercardioid polar pattern provides
excellent acoustic isolation from nearby instruments,
and its voicing characteristics deliver a deep low end,
relaxed midrange, as well as high-frequency content
for aggressive top-end punctuation.
The ND68 dynamic capsule contains a large Mylar
diaphragm, which delivers a rich and detailed
frequency response by combining its large surface
area for tonal balance with its low-mass high-velocity
material for exceptionally fast transient response.
Capable of handling 144 dB SPL, the ND68 will
comfortably manage close micing of high SPL sound
sources.
The ND68 capsule uses a humbucking coil that
attenuates AC hum and electromagnetic interference.
ND dynamic mics can be used with confidence near
speaker cabinets and EMF generating equipment
racks.
The ND68 Memraflex grille is made of a durable tight­mesh grille wire that withstands extraordinarily-rough
treatment. Your microphone remains protected and
looking good gig-after-gig, year-after-year.
For additional protection, the ND68 capsule contains a
hydrophobic cloth membrane which prevents moisture
and debris from reaching the diaphragm.

3. Use the 3-to-1 rule when using multiple microphones.
Place each microphone three times farther from other
microphones as from the desired source.

4. Minimize over-handling of the microphone to reduce
unwanted mechanical noise.

5. Working close to the microphone will increase the
bass tone and also provide increased gain-before­feedback.

Microphone Use and Placement:

Please note that micing techniques are a matter of
personal preference. These are merely guidelines to
assist in the placement of the microphone to gain
optimal performance.

Usage Optimal Placement

Kick Drum Option 1: Remove front drum head and damp the

drum shell with a pillow or blanket. Position the mic on
the pillow or blanket a few inches in front of the batter
head. Having the mic nearer the center of the head will
give your sound more snap, and further out toward the
shell will give your sound more warmth. As an
alternative, position the mic on a small boom stand
with the mic extended into the drum and at a 90 angle
to the batter head.
Option 2: When using a drum with a front resonator
head with a vent hole cut into it, position the mic on a
small boom stand with the mic extended into the drum
through the vent hole and at a 90 angle to the batter
head. Aiming it more toward where the beater strikes
the batter head will give your sound more snap, and
aiming it further out toward the shell will give your
sound more warmth.

System overview

Standard Placement and Use Guidelines:

1. Always point the microphone at the desired source of
sound and away from any unwanted sources.

2. The microphone should be located close to the sound
source to minimize interference from other potential
sound sources.

Large Tom­Tom

On double headed Toms, place mic over the top of
drumhead 1-3" and at a 45° angle to the drumhead
surface and 1-2" in from the drum edge. On single
headed Toms, use above method or place mic inside
Tom from underneath at a 90° angle from the center of
head, 3-5" away.

Bass Guitar
Speaker
Cabinet

Place microphone approximately 1-2" from and at a
90°degree angle to the speaker cone. To reduce
boominess, move the microphone off axis to the cone
from 90° to 45°, or move mic from center of cone to
either edge. Placing the mic nearer the voice coil
(center of the cone) will give a brighter sound, and
farther toward the outer edge will give you a warmer
sound.
