General Product Description

The N/D868 is truly a top performer in any application.
Whether in a live sound or studio environment, the N/D868
is able to handle incredibly high sound pressure levels
without distortion or overriding the input mixer.With a
response specifically designed to “kick” the N/D868 can be
used is “as is”—no additional EQ required. Electrovoice was
the first to utilize the neodymium magnet structure, and it
remains at the heart of our new N/DYM series of
microphones. Experience the leader again for the first time
and hear the difference.

• Designed specifically for kick drum applications in live or
studio environments

• Optimized sensitivity for the high sound pressure levels
found in bass drum micing

• Extended low-frequency response

• No additional EQ required

• Rugged steel construction for exceptional durability

Operation

The low frequency response of the N/D868 microphone
varies with the distance from the sound source. Known as
“proximity effect,” maximum bass response is produced in
“close-up” use with the microphone 1/4 inch from the
sound source. Normal bass response is experienced with
working distances greater than 24 inches.Working close to
the microphone will produce a more robust sound. Close up
positioning of the microphone will also reduce the potential
for feedback from the sound reinforcement system.When,
the bass-boost provides an increase in overall microphone
output level.The mixer gain may be proportionately
reduced, resulting in a reduction of the system’s sensitivity to
feedback caused by sound entering the microphone from
the loudspeakers.

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 Remove drum head and damp with a pillow or blanket. Position the mic on the pillow or blanket a few inches in front of the

drum beater. As an alternative, position the mic on a small boom stand with the mic extended into the drum and at a 90° angel
to the drum beater.

N/D868

Bass Drum Microphone

Standard Placement & 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.

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