N/D868

N/DYM® Bass Drum

Microphone

General 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 “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.

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. Then, the bass­boost 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° angle to the drum beater.

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.
