Assemble dimensions
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.
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
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. PRA528 series work with 9 to 52VDC phantom only. Please make sure
your sound system provide adaquate power to the microphone.

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.
Variable response
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 speech.
Cardioid
Directivity
Maintainence
Uni-directional condenser microphone features very high sensitivity at -39dBV/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 air-conditioning
fan.
Keep capsule and wind screen clean for good audio performance.
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.
