4. The  R-101  requires  no  power  supply  and  is  safe  to  use  on  consoles  with  phantom 

microphone powering, provided that the cabling is wired properly. It should be noted that not 
all  ribbon  microphones  are  compatible  with  phantom-powered  systems,  so  check  the 
manufacturer’s recommendations before  using  other  ribbon microphones.  It  should  also  be 
noted that faulty or improperly wired cables could cause  problems with your R-101. Do not 
patch an R-101 through the mic tie lines of a patch bay if phantom power is enabled on any 
of your mic  pre’s,  as this will give the ribbon element  a  brief but damaging  phantom power 
jolt.

5. Never attempt to test the R-101 or any ribbon microphone with an ohmmeter. A blown ribbon 

could result.

6. Always  provide  adequate  protection  for  your  R-101,  or  any  ribbon  microphone.  If  the 

microphone is to remain set up on a stand when not in use,  place a mic  sock  (supplied with 
every Royer microphone) over  it until  it  is to be  used. Do not  carry the  microphone  around 
without  placing a mic sock over it. Failure to follow this commonsense  practice may yield a 
stretched ribbon and compromised performance.

7. Do  not  allow  the  microphone  to  be  dropped  on  hard  surfaces  such  as  floors  or  tables  - 

depending on how  the  mic falls,  you could stretch the ribbon. The microphone would likely 
continue  to  operate,  but  performance  could  be  compromised  and  re-ribboning  the 
microphone would be necessary to restore normal operation.

Amplification Considerations

The  performance  of  any  non-active  ribbon microphone  is  directly  affected  by  the  microphone 
preamplifier it is paired with. With so many mic  preamps on the market,  how  do you select one 
that gives the  best  possible performance  with  a  ribbon microphone? Additionally,  what  kind of 
performance  can  you  expect  from  the  preamplifiers built  into  your  mixing  desk?  While  most 
preamplifiers will  handle  ribbon microphones  well  in most  recording  situations,  some  preamps 
that work perfectly well  with condenser or dynamic mics may prove to be poor performers with 
ribbons.

To  begin,  we  must  understand  the  fundamental  differences  between  ribbon  microphones  and 
other  popular  types,  namely  condenser  and  moving  coil  dynamics.  A  ribbon  microphone  is 
actually  a  dynamic  microphone  that  uses  a  corrugated,  extremely  low  mass  ribbon  element, 
rather  than  a  coil/diaphragm  assembly.  For  this  writing,  any mention  of  dynamic  microphones 
will relate to moving coil dynamics.

All condenser microphones have a  built-in preamplifier called a head amp,  and therefore put out 
a  hefty  signal.  Because  the  signal  is buffered  through  the  head  amp,  the  output  impedance  is 
rather low  and less affected  by  the  input  impedance  of  the  microphone  preamp. Most  dynamic 
(moving  coil)  microphones  generate  a  healthy  enough  electrical  current  to  work  well  with  a
