General Product Description

Designed specifically for horns, drums, acoustical and electric guitars, the
N/D468 provides a smooth, natural sound, capturing the excitement of
the instrument.The supercardioid pattern provides superior rejection and
acoustic isolation in any application.An innovative EV design harnesses
the increased power of a neodymium based magnet design, allowing a
large-diameter voice coil (up to 50% larger than other mics) for
dynamic, efficient microphone performance. N/DYM

®

offers the power
and clarity to “cut through the mix.”Whatever your instrument
application the N/D468 is sure to be a top performer.

• Designed specifically for musical instruments

Flexible mechanical design for optimum positioning

• Supercardioid pattern for exceptional acoustic isolation and

feedback rejection

• Accurate response, even in high sound pressure levels (SPL)

• Rugged steel construction for exceptional durability

Operation

The low frequency response of the N/D468 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 close-miced, 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
Electric Guitar and Bass Guitar Amplifier 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.

Tom-Toms On double headed Toms place mic over the top of drum 1-3" and at a 45° angle to the drum

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.

Snare Drum Place mic 1-3" above the heads, 1-2" in from the rim. Aim each mic at the top heads angled

down about 45°. If the drum rings, tape deadening material to the head or use damping rings.
For more “snare” sound place a 2nd mic underneath aimed up at the bottom of head.

Cymbals Place microphone one to two feet above the top of cymbals.
High-Hat Place 5 inches above outside edge at a 45° down angle.
Brass 6-24" away, and on axis with the bell of the instrument.
Acoustic Guitar Place mic 6-12" from where finger board joins the body.

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.

Warranty

This product is guaranteed against malfunction from any
