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.

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 speech.

Using condenser gooseneck microphone

Uni-directional condenser microphone features very high sensitivity at -40
dBV/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.

Assembl e dimensions

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. E322 work with 9~48VDC 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 none-professionals, 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 sub-sonic
filter to cut air-conditioner and floor vibrations. And allows full flat when used in
controlled environment.

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.

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.
