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 distor tion. 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 wor ki ng at co nt rolled en vi ronment, or for acous ti c
meas urem en ts. Alth ou gh peopl e p er suit fla tn ess, but fo r n oneprofessionals, 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.
Using dynamic gooseneck microphone
Super Cardioid dynamic microphone features very high sensitivity at 43dBV/Pa for high intelligible speech application. Reduced off-axis
sensitivity to keep lower background noise and maximized on-axis
sensitivity for highest gain before feedback in live sound system.
User shall keep 15 cm to 40 cm from microphone, and maintain average
speech level. Up close will result excessive bass due to proximity effect
which interfere intelligibility. Maintain their speaking in front of the
microphone for high gain before feedback.
Quality conference microphone incorporating built-in limiter to prevent
distortion due to exciting user or close up speaker.
Choices of gooseneck for various demands. For aesthetic, single or double
bend goosenecks are better choice over fully bend design. Low bending
noise is another important feature of good gooseneck microphone. User
shall not bend the gooseneck to hard or rush which may generate excessive
noise which disturbs the audience.
In most cases, each attendee has his own microphone or share a
microphone every 2 attendee. Although there are numbers of microphones
in one space which is not a good criterion for feedback problem, system
operator shall keep as less turn-on microphone as possible for best result.
Auto-mixer is a good choice for multiple microphones installation which
limit the number of turn-on microphone at the one time. Advanced auto
mixer features dynamic threshold and auto gain reduction according to the
number of turn-on microphones to keep the same system gain.
Wind screen is vital for windy environment such as outdoor or close to airconditioning fan.
Keep capsule and wind screen clean for good audio performance.
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
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.

Maintainence
Dynamic 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.
