ND66
▪ Premium small diaphragm condenser element
▪ Clean, crisp, and detailed condenser sound
▪ Easy mic placement with locking rotating head
▪ Selectable -10dB and -20dB pads
▪ Selectable 75Hz and 150Hz high pass filters
The Electro-Voice ND66 is a robust, high-performance
small diaphragm condenser instrument microphone.
The ND66 contains a self-biased small diaphragm
condenser element which is vividly responsive to the
complex dynamic nature of percussive and stringed
instruments, delivering a clean, crisp and detailed
sound.
With the ND66 exclusive locking rotating head, achieve
ideal mic placement in virtually any situation by merely
pushing a button, rotating the head into position, then
releasing the button to lock the head's position.
ND66 contains selectable -10 and -20dB pads which
provide the necessary gain reduction to prevent the
mic element from overloading when micing very loud
or high-transient sound sources.
ND66 contains selectable high pass filters which are
strategically chosen at 75Hz and 150Hz to eliminate
bothersome low frequencies from the signal path.

System overview
Using the rotating head
The ND66 head will rotate up to 90° with seven
positive locking positions within its rotation range.
Caution!
Attempting to rotate the head while the un-
locking button is not pushed may result in
damage to the microphone.
To rotate the head, do the following:
1. Push and hold the unlocking button to unlock the
head.
2. While holding the unlock button down, rotate the
head to the desired position.
3. Release the unlock button and gently rotate the head
to the nearest positive locking position.
The lock should click into place.
Using the pads
The ND66 head contains selectable attenuators (pads)
which affect the output level of the microphone
capsule feeding the mic’s built-in preamp. The proper
setting will help prevent overloading the built-in
preamp when micing very loud or high-transient sound
sources.

The center position (marked 0) applies zero
attenuation before the mic’s preamp.
The left-hand position (marked -10) applies
10dB of attenuation before the mic’s built-in
preamp.
The right-hand position (market -20) applies
20dB of attenuation before the mic’s built-in
preamp.
Using the hi-pass filters
The ND66 contains a 3-position sliding switch whose
selected position will engage high-pass filter settings.
Adjusting the filter setting requires a small flat head
screwdriver (or some other means of sliding the
switch) using the switch’s slot as a leverage point.
With the slot in the sliding switch in the
center position (as shown), the filter is flat
and there is no roll-off applied.
Sliding the slot upwards revealing 75 (as
shown) engages a 12 dB per octave roll-off
at 75 Hz.
