mics on the live stages. One of the consideration is durability. The
studio condenser cannot withstand the mechanical challenges as
those dynamics which can easily handle.
Now this is no more a consideration for those who want a studio
grade true condenser microphone when Superlux S125 is ready for
all challenges.
Superlux S125's wide and flat frequency response is the same as
studio condenser, because it is a studio grade microphone as well.
It provides very fine detail resolution, that brings out every details
the artist performed. With switchable -10dB pad, the S125 can also
handle high SPL sound sources. Switchable 3rd order low cut filter
cut out those un-wanted stage noises for clean sound even in noisy
environment.
The triple layers wind screen drop down blowing noises to the
minimum when S125 facing up-close settings.
Not only a professional choice for vocal miking, S125 is also a
professional choice for instrument miking from strings, winds, to
percussions.
Gold plated contacts between capsule and electronics provides
stable performance, yet the convenience the disassemble the
capsule without a tool. Die-cast casing and steel strengthen
processed grill wind screen results sturdy structure, and extreme
low handling noise. All these efforts built up this perfect (almost)
microphone for all performing art professionals.

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
Condenser
Extremely light weight diaphragm, very sensitive to sound. Very small
versions available for hiding applications. High performance condenser
microphones are regarded as standard equipment of recording studios for
extreme detail capturing. Operates with power, such as phantom or battery.
Powering microphone
Condenser microphones work with power. Professional standard is 48VDC
phantom power. Some microphones work with lower voltage as low as
1.5VDC, such as battery power model. S125 work with 48VDC phantom
only. Please make sure your sound system provide adaquate power to the
microphone.
About Frequency Response
Flat
Suitable for working at controlled environment, or for acoustic
measurements. Although people persuit flatness, but for noneprofessionals, it is a challenge to makes 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 subsonic filter to cut air-conditioner and floor vibrations. And allows full flat
when used in controlled environment.
Directivity
Cardioid
Picks up most signal on axis. Rejects side and picks up least to the back.
Suitable for live sound re-inforcement. Apparent proximity effect and most
singer likes to take this bass boost advantages which is not good for
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.

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.
