Страница 4: ...here are a few important facts about ribbon microphones that are key in understanding how to use them intelligently 1 The R 101 is a side address bi directional microphone and its rejection in the dead areas is very strong Due to this directionality the R 101 should be placed at 1 3 times the distance normally used with omni directional microphones or about the same distance used for cardioid micr...

Страница 6: ...ed for efficient operation of a ribbon microphone the noise characteristics of the preamp play a pivotal role in overall performance of the captured acoustic event 3 Load characteristics A suitable preamplifier should have input characteristics that impose the least amount of loading on the ribbon element In other words the input impedance should be high enough that its effect on the performance o...

Страница 7: ... amplifiers and alternating current motors are the most likely sources of radiated noise Building wiring and electrical utility transformers are other likely sources A well designed microphone provides shielding to minimize the effects of stray magnetic radiation but complete isolation is impossible and the result can be hum or buzz Ribbon microphones can potentially manifest this condition to a g...

Страница 9: ...n advantage is to make things sound more real than real For example many voices and certain musical instruments produce fundamental frequencies within the bass range below 150Hz or so but the fundamentals are weak If a microphone which has no proximity effect and a rising high frequency response is used on an upright piano or on a person with a thin weak voice the recorded sound is likely to sound...

Страница 11: ... the enemy Air movement is far more damaging to ribbon microphones than high SPL s Some sound sources can generate powerful blasts of air that should be avoided Kick drums and electric guitar and bass amplifiers are typical examples of sound sources that can produce harmful air currents One way to determine if the air pressure is excessive is to place your hand in front of the sound source the kic...
