Descr iptio n

The D109 is a high impedance, cardioid dynamic microphone for using a
microphone with guitar amp or other high impedance input devices.
Ordinary low impedance microphone will not work with such devices. The
mesh grill is a effective pop screen to filter wind noise and speaking pop
when using the microphone close to the mouth. Cardioid pattern provide
adequate gain before feedback while the guitar amplifier is at close distance
and at un-sensitive angle.

The D109 comes with a 6-meter, XLR3F to 1/4" phone plug cable and mic
clip.

Fe ature s

! Wide frequency response to clean instrument pick up.

Knowing your microphone

Superlux provides variety selection of microphones for professionals and amatures. To
know your microphone is the first step to successful result.

Type of transducer

Dynamics

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.

About Frequency Response

Flat

Suitable for working at controlled environment, or for acoustic measurements.
Although people persuit flatness, but for none-professionals, it is a challenge to m akes
it works as expectation.

Popular curve response

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.

Variable 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.

Directivity

Super Cardioid

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.

Using a handheld microphone

For best s ignal to noise ratio, distance from the handheld microphone to the sound source
shall be as shor t as possible.

For higher gain before feedback and lowest background noise, the microphone shall be
pointed directly to the sound so urce. ( refer to the illustration below) The sensitivity of a su per
cardioid microphone i s highe st on axi s and low est at 120 to 135 degrees.

To avoid in terfe rence between multiple microphones, e ach sound source shall be pick ed-up
by one microphone, use as less microphones as possible in o ne space, or turn-on as less
microphones as possi ble at th e same ti me.

To reduce crosstalk between micropho nes, an 1:3 guide line shall be follow: The distance
between mi cropho ne A to the sound sou rce A is "1", the distance between any other
microphone to the soun d source A s hall be m ore than 3 t imes.

When the (super) cardioid microphone get closer to the sound source, the low freque ncy
response is boosted , as so call "proximity effect". Experience singe r ta kes advan tages 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 us ed. Same idea to reduc e the bass by
increase the di stanc e to reduc e the bas s when ne eded.

Reflec ting surface affect so und as well. Bewa re of these s urfac es such as w all, table, or fl oor.
Place t he mic rophon e away f rom the h ard surfaces o r direc tly contact t hese surfaces to form a
pressure zone mi cropho ne.

When using the microphone outdo or or in windy environment, addit ional foam wind screen
helps to reduce wind noi se.

Keep g rill pop screen clean to avoid degrading the sound quality. Do not expose the
microphone at high hum idity /temp erature environment to avoid damage.

Mounting the microphone

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.

Maintainence

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.
