2. Do not expose the microphone to direct blasts of air or strong air currents! Use a windscreen
or suitable pop filter when close miking a vocalist or certain types of wind instruments. P-
popping does not necessarily damage the ribbon element but may produce unacceptable
preamplifier overload and could cause damage to speaker systems.
3. Do not expose the microphone to liquids or caustic smoke.
4. Do not expose the microphone to strong EMF (electro-magnetic fields), such as the power
transformers in amps, or hum may result.
5. Use a soft cloth to clean the microphone body. A small amount of denatured alcohol can be
used to remove fingerprints and other stains.
6. Keep metal filings away from the microphone at all times. The R-122V’s strong magnets can
attract even the smallest metal particles into the ribbon transducer, which can result in
compromised performance and the need for a re-ribbon.
7. When not in use, store the microphone, power supply and cabling in it’s protective case.
8. Leave disassembly of the microphone to a trained technician. Disassembly of the microphone
will void your warranty. There are no user-serviceable parts inside.
9. The R-122V’s power supply has no user serviceable parts inside so do not attempt to make
repairs. There are lethal voltages present that can cause serious injury if mishandled. Leave
servicing to a qualified electronic technician.
The vacuum tube located inside the microphone body is a sub-miniature type that is
permanently wired into place. The mil-spec 5840 tube has a minimum service life of over
50,000 hours, so tube failure is highly unlikely. However, if the microphone should develop a
vacuum tube related problem, it must be returned to the factory for service.
Voltage Conversion
The R-122V is energized from a dedicated power supply that operates from an AC voltage
source. The supply can be configured to operate with the following voltages:
100-120 Volts 50-60HZ
220-240 Volts 50-60HZ
Fuse Replacement
The AC line fuse is located within the IEC power connector. Your power supply was shipped
with a fuse rating suitable for the country in which it was sold. Should the fuse require
replacement, two types are used.
200-ma, Slow-Blow type for 100-120 volt operation
100-ma, Slow-Blow type for 220-240 volt operation
If when replacing a blown fuse the new fuse blows, your power supply must be serviced. Never
substitute a larger size fuse in an attempt to make a faulty power supply work! This invalidates
the R-122V’s lifetime warranty and could precipitate a fire, shock or other health hazard.
