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.

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 distortion.

Due to structure limit, dynamics cannot be built as small as condenser, but dynamics doesn require power to operate.

Distance to source

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.

Using a headphone microphone

4

Avoid violent shock or drop to prevent damaging to the precision vibrating system in the headphones.

4 Do not over bending or cable warping that may cause contact problem for long term use.

4 To protect your hearing, do not expose to long term high sound pressure level, keep the volume down especially wearing the headphones.

4 Do not use the headphones when driving a vehicle or under similar safety consideration. Unless the headphones/headsets were used for communication.
