Electro-Voice N/D868 User manual

Technical Specifications:
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 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.

Standard Placement & Use Guidelines
1.Always point the microphone at the desired source of sound, and away from any unwanted sources.
2.Themicrophoneshould be locatedclose to thesound source tominimize interference fromotherpotential soundsources.
3.Usethe 3-to-1rulewhen using multiplemicrophones. Place eachmicrophone three timesfarther from othermicrophonesas fromthe
desired sound source.
4.Minimizeover-handling ofthe microphone toreduce unwantedmechanicalnoise.
5.Working close to the microphone will increase the bass tone and also provide increased gain-before-feedback.

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.
