LSM50C, LSM900 & LSM1000 Microphones

Microphone Picture


The LSM family of electret condenser microphones are high quality omni-directional microphones featuring an extended frequency response with an excellent transient response.
Three different models offer a choice in sensitivity.
Unlike so many products today, they are repairable should the need arise.

The versatile characteristics of the LSM series of microphones enables their use on a very wide range of musical instruments and applications. These include acoustic stringed instruments such as guitar, banjo, violin, lute and bouzouki. They are also suitable for drums, percussion, brass instruments, flute, choirs, conferences and surveillance applications. Multiple LSM900s can also be used successfully on grand piano, piano accordion, bass clarinet and percussion instruments such as marimba, vibraphone and xylophone. 
The microphones are free of the bass boosting proximity effect found when using most cardioid microphones close to a sound source.

In most instrument applications the LSM microphone can be mounted closer to the sound source than could a conventional microphone. This results in greater loop gain (i.e. louder signal before feed back), even though the LSM microphone has an omni-directional pattern.
