USER GUIDE
RSM-4 — Studio Ribbon Microphone for Instruments & Vocals
Your RSM-4 microphone was carefully packed at the factory, and the shipping carton and internally padded gift box were designed to
protect the unit during shipping. Please always store your mic in the padded gift box and also retain the shipping container for sub-
sequent 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-4, 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 as-
sembly replaced for a fixed charge (see Service section).

FEATURES
Congratulations on purchasing the Nady RSM-4 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. Especially suited for recording
guitar amplifier cabinets, the versatile RSM-4 is also great on 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 classic ribbon mics, the RSM-4
meets the stringent requirements of even the most demanding digital recording and live broadcasting
applications.
This manual covers the operation of the RSM-4 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.
• MPF-6 Pop Filter (highly recommended, as ribbon micro-
phones are very susceptible to damage from strong air
blasts, as with percussive sounds during recording)
• Unparalleled, uncompromised sound of a classic ribbon (velocity)
mic
• Ideal for close miking of guitar amps and cabinets and many
other vocal/instrument recording and live sound applications
• Low tension 45 mm long, 6 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
(dual) mics setups (source in principal axis of one 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
