[. . . ] RSM-4 Studio Instrument & Vocal Ribbon Microphone USER GUIDE 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. [. . . ] 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-4 ribbon microphone · Foam padded wooden storage box · Mic clip · Velvet drawstring storage bag · User Guide · Warranty card 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 · The unparalleled, uncompromised sound of a classic ribbon (velocity) mic · Versatile design for numerous applications, including close miking of guitar amps and cabinets, and many other vocal and instrument recording and live sound uses · Low-tension 45mm long, 6 micron thick aluminum ribbon design with typical "large, mellow" ribbon audio reproduction with smooth, natural extended low and high ends · Fast accurate transient response, ultra-high 165 dB SPL capability, unmatched transient response and overall stunning realism · Figure-8 audio directional (pickup) pattern for both front and rear side, with extended sweet spots (as compared to large diaphragm condenser mics), and slightly different frequency responses from front and rear side. Also, increased off-axis high frequency response on sides, with decreased high response above and below on-axis (though lower audio levels). · Individual recording volume control of separate sources, through use of stereo mic setups wherein isolation is achieved by placing the source so that it is in the principal axis of one mic and the off-axis null of the other · Manufactured with the finest materials with a machined housing with advanced internal shock mount construction for the highest 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-4 please always follow these 4 precautions: 1. Always protect your RSM-4 from any hard knocks, such as from dropping the mic, or not properly padding in shipment, as such jolts can destroy the ribbon assembly. Prevent any sudden or strong blasts of air movement from ever reaching your microphone, as they can tear and destroy the fragile ribbon. 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. Never intentionally or accidentally apply any phantom power from your mixer or a phantom power supply to your RSM-4 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-4. When not in use, always keep the microphone in the padded wooden box provided. [. . . ] 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.
