3. When using the R-121 to record loud signal sources, placing
the microphone slightly off axis to the signal source (either hor-
izontally or vertically) minimizes the effect of high pressure
sound levels displacing and possibly damaging the ribbon ele-
ment.
4. The R-121 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-powering 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-
121.
Do not patch an R-121 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-121 or any ribbon microphone
with an ohmmeter. A blown ribbon could result.
6. Always provide adequate protection for your R-121, 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 rib-
bon 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 contin-
ue to operate, but performance could be compromised and re-
ribboning the microphone would be necessary to restore normal
operation.
