sound. Basically, what you hear at the amp is what you get in the control room and in your 
recordings.
Choirs and Orchestras can be picked up well using a pair of R-122V's. Place the microphones 
at a height of ten feet or so and a few feet behind the conductor. The microphones should be 
spaced apart approximately one foot and angled, one toward the left and one toward the right, or 
in the classic Blumlein configuration.
Drums and Percussion instruments sound full-bodied and natural when recorded with a pair of 
R-122Vs. For a drum set, placing the microphone(s) at a distance of four to six feet above the kit 
works very well without making the cymbals sound splattered. A kick drum should be miked at a 
distance  of  at least 18 inches  and  possibly  used  in  conjunction  with a pop filter  to  prevent 
excessive ribbon movement. If the front head has a hole cut in it, position the microphone away 
from the hole to avoid excessive air blasts. An R-122V used as a mono room mic, four to six feet 
in front of the kit and compressed, will yield a surprisingly large, full drum sound.
For closer miking of a kick drum (10 to 18 inches), the microphone should be leaned forward at 
a 45-degree angle to protect the ribbon element from excessive plosive forces (See Example 3).
This   microphone   position   also   provides   good   kick   drum   isolation   because   the   top   of   the 
microphone, which does not pick up sound, is aimed at the rest of drum kit.
Recording Loud or Plosive Sounds
With all ribbon microphones, wind is 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 cabinets 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 kick drum, the guitar cab, etc.) 
and see if you can feel actual air movement. If you feel air movement, do not put your ribbon 
microphone there. 
A simple technique that can avert damage due to over-stressing the ribbon is as follows: After 
choosing the optimum placement for the microphone, slightly angle the microphone in such a 
way that the percussive wave is not directed head on at the front of the mic. Often, a slight 
angular tilt (either vertically or horizontally) is all that is required to prevent harm to the ribbon 
(see examples 1, 2 and 4). It should be noted that as the microphone is tilted vertically, relative to 
the sound source, the highs will begin to roll off.

Technique
Slight off-axis positioning will minimize stressing 
the ribbon on loud sound sources
