Stand Mounting the PM9
The PM9 can be mounted to any standard microphone
stand using the included mic stand holder. If you are
usingaUSstandard5/8-inchmicstand,removetheEuro
adapter by unscrewing it from the mic holder. Slide the
microphone into the holder from the rear to the front
with a downward motion until it snaps into place.
Microphone Placement
To help maximize the quality of your performance, you
must pay careful attention to the placement of your PM9,
and specifically, how it is positioned for the instrument
orvocalistthatyou’remiking.Asyoubecomemore
experienced in miking techniques, you’ll quickly realize
the microphone placement is critical to getting the
sound you want while maximizing gain before feedback.
When placing the mic around any instrument or sound
source, take notice of the postion of the front of house
and monitor loudspeakers. In general, it’s good practice
to set the microphone behind the main or front of house

position, be sure to check that the mic input is still set
to a good level without clipping, as described in the next
section.
Setting Up the Signal Level
In order to get a good signal, first be sure that the PM9 is
connected to a mixer or recorder input that is microphone
level. Most quality mixers, mic pre’s and recorders
providemicrophoneinputswithamictrim(“Trim”AKA
Mic Gain or Level) control. The purpose of the mic trim
control is to set a good signal level and minimize any
noiseassociatedwiththemicinputselectronics.Agood

when the input is at overload; the level which distortion
begins to occur. To set a good clean level, set the PM9 up
in front of the desired sound source and slowly turn up
themictrimuntilyouseetheClipLEDlightup.Then,
turn the trim control down until the LED does not light
any more. On most microphone inputs, the best setting
is when the trim control is turned up as high as possible
withoutlightingthePEAKLED.
The Proximity Effect
Allcardioidoruni-directionalmicrophonesexhibita
phenomenon known as “proximity effect”. The proximity
effect is the increase in low frequency response a
microphone exhibits as it is moved closer to the sound
source.Vocalisttendtolovethiseffectsincewhenthey
get really close to the mic they get the “FM radio”, big
basssound.Agoodvocalistwithgoodmictechniquewill
use the proximity effect to adjust their tonal response in
real time. The key to developing the best mic technique
is experimentation, along with awareness of the general
principle that, the closer your PM9 is to a signal source,
the greater the bass response. The proximity effect’s bass
lift is caused by the amount of pressure present at the
ports that are used to create the directional pattern. Since
omnidirectional microphones do not have ports, they do
not have proximity effect.
