Specialized Recording Techniques

Recording on the back side of the R-122

The  R-122 incorporates an  “offset  ribbon”  design that enables it  to handle high  sound pressure 
levels  such  as  those  produced  by  loud  guitar  amplifiers  and  other  instruments. An  interesting 
phenomenon  as  a  result  of  this  offset  ribbon  construction  is  that  the  R-122  records  slightly 
brighter on its back side than on its front (logo) side,  when the microphone is three feet or closer 
to the sound source. This can be extremely useful when a brighter response is desirable,  such as 
when recording acoustic instruments or vocalists. 

When recording vocals on either side of an R-122,  a quality pop filter (such as the Royer PS-101 
metal  pop  screen)  is  essential  to  protect  the  ribbon  element  from  wind  blasts.  As  with  any 
figure-8  microphone,  the  front  side  of the  R-122 is  in-phase  and the  back  side is  out-of-phase. 
We  suggest that that you reverse the  phase  polarity on your microphone preamplifier to achieve 
in-phase recordings when tracking on the back side of an R-122.

Normal  proximity  effect  (increase  of  bass),  which  is  prevalent  on  the  R-122  and  all  ribbon 
microphones,  occurs  normally  at  4-6  feet  from  the  microphone  and  increases  with  closeness. 
Vocalists and voice-over talents often take advantage of proximity effect to give an authoritative 
quality or rich texture to their voice.

Cautionary Note:

It is important to note that the SPL handling capability of the rear side of the R-122 is lower than 
its front side. The R-122 is rated for 135dB SPL on its front side, but recordings on the rear side 
should not  exceed 115dB  SPL.  When tracking loud sounds on the  front  side, the  R-122’s offset-
ribbon design allows ample  space for rearward  excursions of  the  ribbon. However, tracking on 
the back side causes the ribbon to move forward towards the front side of the microphone, where 
the  internal  dampening  screen  is  much  closer  to  the  ribbon  element.  Rear-side  recordings  of 
loud,  low-frequency  sounds, or  vocalists with  no  pop  filter,  can  drive  the  ribbon  into the  front 
dampening  screen,  creating  noise  and  possibly  damaging  the  ribbon  element.  Limit  back  side 
recording on your R-122 to lower SPL sound sources.

Care & Maintenance

The  R-122 is a well-built  precision instrument. All that is required to ensure  proper operation of 
this microphone is to follow some commonsense rules.

1. Avoid transducer damage by not exposing the microphone to severe shock or vibration. If the 

microphone is accidentally dropped,  test it  to see if damage has occurred  before returning it 
to service. Low output or a dull sound would indicate a damaged ribbon.

2. Do not expose the microphone to direct blasts of air or strong air currents! Use a windscreen 

or suitable blast  filter  when close  miking a vocalist or certain types of wind instruments.  P-
