RSM-2 Ribbon Studio Microphone
USER GUIDE
Congratulations on purchasing the Nady RSM-2 Ribbon Studio Microphone. This superior neoclassic
microphone is designed for use in contemporary, state-of-the-art studios, yet offers the unique
natural sound previously only available on such classic large ribbon mics as the legendary RCA 44,
which is still used to make great recordings today after almost 70 years. Perfect for recording studio
vocals, acoustic instruments, strings, horns, orchestras and choral groups, ambient instrument audio,
and many live sound applications. Powerful and versatile, and with the unmatched natural sound of
classis ribbon mics, the RSM-2 meets the stringent requirements of even the most demanding digital
recording and live broadcasting applications.
This manual covers the operation of the RSM-2 microphone and the available optional accessories.
To take full advantage of the superb features of your microphone, and to enjoy long and trouble-free
use, please read this user’s guide carefully. As ribbon microphones are, by their design, very sensitive
to damage from mishandling and use, it is very important to read and observe the precautions below
about proper use.
UNPACKING, INSPECTION, STORAGE AND TRANSPORT
Your RSM-2 microphone was carefully packed at the factory, and the shipping carton (and soft padded box) was designed to protect
the unit during shipping. Please retain this container for subsequent transport and in the highly unlikely event that you ever need to
return your microphone for servicing. Please note: since the ribbon assembly of the RSM-2, as with all ribbon microphones, is extremely
fragile, you must verify immediately upon receipt of your microphone that it has not been damaged during shipment and is operating
correctly. The warranty on this microphone does not extend beyond an initial inspection, since these microphones can be so easy damaged during handling and use. If the unit arrived damaged please return it immediately to where you bought it. Units that are damaged
in use can be returned to Nady Systems and the ribbon assembly replaced for a fixed charge (see Service section below).
STANDARD ITEMS SUPPLIED
• RSM-2 ribbon microphone with attached stand mount
and XLR cable
• Instruction manual
• Warranty card
• Soft padded box
OPTIONAL ACCESSORIES
• MPF-6 Pop Filter (highly recommended, as ribbon microphones are very susceptible to damage from strong air
blasts, as with percussive sounds during recording)
FEATURES
• Unparalleled, uncompromised sound of a classic ribbon (velocity) mic
• Low tension 50 mm long, 2 micron thick aluminum ribbon design for characteristic “large, mellow” ribbon audio reproduction with
smooth, natural extended low and high ends
• Unmatched fast, accurate transient response, ultra-high 165 dB SPL capability, and overall stunning realism
• Figure-8 audio directional (pickup) pattern for front and rear sides, extended sweet spots (as compared to large diaphragm condenser
mics), slightly different frequency responses from front and rear, and increased off-axis high-frequency response on sides, with
decreased treble and lower audio levels above and below on-axis
• Discrete volume control of separate sources possible with stereo mics setups (source in principal axis of mic and in off-axis null of the
other)
• Manufactured with the finest materials, machined housing, and advanced internal shock-mount construction for structural integrity and
rugged reliability
WARNING / PRECAUTIONS
The active element of your microphone is a very thin corrugated
aluminum ribbon clamped under light tension and mounted
between the poles of a strong magnet. This design enables it to
produce warmest, most natural sound available from any type of
studio microphone. However, it also makes this the most sensitive
and fragile studio microphone available. All ribbon microphones
require special care or they will be seriously damaged. In order
to ensure long life for your RSM-2 please always follow these 4
precautions:
1. Always protect your RSM-2 from any hard knocks, such as
from dropping the mic, or not properly padding in shipment, as
such jolts can destroy the ribbon assembly. Always handled with
complete care.
2. Prevent any sudden or strong blasts of air movement from
ever reaching your microphone, as they can tear and destroy the
fragile ribbon. Never blow into your RSM-2! When using, always
utilize a pop filter, such as the optional Nady MPF-6, to prevent
any percussive sounds from damaging the ribbon. Such filters also
prevent damage from moisture from mouth spray;
3. Never intentionally or accidentally apply any phantom power
from your mixer or a phantom power supply to your RSM-2 as
it can burn up the ribbon. Please always check carefully before
connecting your ribbon mic that there is no phantom power being
provided to the RSM-2.
4. When not in use, always keep the microphone in the padded
soft case provided. Also, always store the mic in a vertical position
because, over time, the 2” long ribbons can sag, gradually
degrading performance if the mic is stored on its side.
Note: damaged ribbons are not covered by warranty and there will
be a charge to replace the element.
USING THE OPTIONAL MPF-6 POP FILTER
The optional MDF-6 pop filter should always also be used with
your RSM-2. This pop filter should be placed between the sound
source and the microphone to prevent percussive sound blasts
and air movement from damaging the very fragile ribbon assembly
of the RSM-2. It is also useful in keeping mouth spray out of
the microphone, which can also degrade or destroy the delicate
ribbon.

Do not attempt to service this unit yourself as it will void your warranty. Please note that due to the extremely delicate nature of
ribbon mics, which can easily be damaged by misuse and mishandling (as noted under Warning / Precautions section above), the
ribbon assembly of the RSM-2 is not covered under warranty. Check your unit carefully upon receipt and return to place of purchase
immediately if there are any problems with the mic. After that, the standard Nady warranty will only apply to defects in materials and
workmanship other than the ribbon assembly. It these are damaged, please contact the Nady Service Department for a quote for
replacement of the ribbon assembly.
