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

Active aluminum ribbon microphone consists of two parts: an electro-
magnetic transducer and an impedance converting circuit. The electro-
magnetic transducer applies a unique magnetic circuit field with a strong Nd
magnet. The aluminum alloy ribbon, with a thickness of only 2.5 microns,
is suspended between two poles and vibrates in synchrony with the
incoming acoustical energy (sound waves). Due to the extremely low mass
of the ribbon, the transducer of this microphone boasts a premium transient
response in converting acoustic energy into electronic signals. Whether at
low / high frequencies or low / high sound pressure levels, the R102 series
delivers a precise reproduction of the original sound.

Powering microphone

R102 series ribbon microphones work with power, so we call it active
ribbon microphone. Professional standard is 48VDC phantom power.
R102 series work with 48VDC phantom only. Please make sure your
sound system provide appropriate power to the microphone.

About Frequency Response

Flat

Microphones with flat response are suitable for working at controlled
environment, or for acoustic measurements. Although people expect
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 emphasizing are
typical skill.

Directivity

Select or set the directivity of your microphone for stereo recording, for
various music instruments, vocal, speech, and environmental sound
pick-up. Pair of spaced omni can be used for A/B stereo, pair of
near coincident cardioid can be used for ORTF, and pair of coincident XY
can be used for Blumlein stereo.

Close miking or distant miking sound very differently. Vocal recording
or live performance practice close miking mostly. Suitable proximity
effect is one desired target, and lower feedback problem is another
factor for live sound application.
While distant miking is common practice for recording, especially
stereo pair recording with large group of performers, such as orchestra
or choir.
Distant miking generally picks up less bass section with pressure
gradient type of microphone (cardioid, figure-8, shotgun...) due to
acoustic nature and lack of proximity effects.
Rich bass with distant miking can be recorded with pressure type of
microphone (Omni), which performs the same frequency response with
close or distant pick- up.

Figure 8, bi-directional

Equal sensitive to both ends, and rejects the sides. It' s good to noisy
environment to reject distant noise and low frequency and also a good
choice for stereo recordings, such as Blumlein. And this is typical
pressure gradient characteristic.

Distance to source

Maintenance

Ribbon microphone shall be kept in low humidity environment for best
sound performance. Store the condenser microphones in air-
conditioned room or dehumidifier to keep away from moisture.
Clean air is another important factor. Keep away from smoking
environment to avoid tar residuals.

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
exactly 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.
