About Frequency Response
Suitable for working at controlled environment, or for acoustic measurements.
Although people persuit flatness, but for none-professionals, it is a challenge to makes
it works as expectation.
Flat
Based on years of practical experience of pro users. There are curves to be build for
various applications, so that it is very simple to use the microphone for the purpose.
Limiting bandwidth, and emphasing are typical skill.
Popular curve response
Incorporating switchable filters to elliminates interference, such as sub-sonic filter to
cut air-conditioner and floor vibrations. And allows full flat when used in controlled
environment.

Mounting the microphone
Maintainence
Pressure gradient microphone is very sensitive to vibration. Suitable shock mount for
high performance microphone is necessary for extreme low noise recording. Sturdy
stand can set the microphone excatly at the sweet spot and keep it there. Choose heavy
duty microphone stand for studio condenser microphone which weights much more
than handle microphone.
Superlux provides wide range of microphone stands for various demands. Big Foot
Willie is specially developed for large condenser microphones that able to support 2
large microphones with stereo bracket for single point stereo recording.
Extension foot on all the 'E' versions serve to mount heavy studio microphone in limit
space live sound applications.
Using a handheld microphone
For best signal to noise ratio, distance from the handheld microphone to the sound source
shall be as short as possible.
For higher gain before feedback and lowest background noise, the microphone shall be
pointed directly to the sound source. (refer to the illustration below) The sensitivity of a super
cardioid microphone is highest on axis and lowest at 120 to 135 degrees.
To avoid interference between multiple microphones, each sound source shall be picked-up
by one microphone, use as less microphones as possible in one space, or turn-on as less
microphones as possible at the same time.
To reduce crosstalk between microphones, an 1:3 guide line shall be follow: The distance
between microphone A to the sound source A is "1", the distance between any other
microphone to the sound source A shall be more than 3 times.
When the (super) cardioid microphone get closer to the sound source, the low frequency
response is boosted, as so call "proximity effect". Experience singer takes advantages of the
proximity effect to improve the richness of his/her voice or to increase the bass of the
instrument as if an extremely high quality equalizer is used. Same idea to reduce the bass by
increase the distance to reduce the bass when needed.
Reflecting surface affect sound as well. Beware of these surfaces such as wall, table, or floor.
Place the microphone away from the hard surfaces or directly contact these surfaces to form a
pressure zone microphone.
When using the microphone outdoor or in windy environment, additional foam wind screen
helps to reduce wind noise.
Keep grill pop screen clean to avoid degrading the sound quality. Do not expose the
microphone at high humidity/temperature environment to avoid damage.
Condenser microphone shall be kept in low humidity environment for best sound
performance. Store the condenser microphones in airconditioned room or dehumidifier
to keep away form moisture. Clean air is another important factor. Keep away from
smoking environment to avoid tar residuals.
Durable and simple structure, operates in all kinds of environments. A good dynamic
microphone is capable to operate at very high sound pressure level without distortion.
Due to structure limit, dynamics cannot be built as small as condenser, but dynamics
doesn require power to operate.
Dynamics
Narrower than cardioid pattern. Suitable for multiple microphone setup. Least sensitive
angle pointing toward side to rear where most stage monitors are located. Same
proximity effect as cardioid microphone.
