MSRP: $360 Bidirectional Ribbon Microphone

Nady RSM-3

Description

The RSM-3 is a rebadged Alctron HRM-10, itself a copy of Royer’s R-121.

The ribbon measures 35mm by 5mm by 2 microns in thickness. It is advertised as being offset from front to back, providing slightly different sounds and making the front side capable of higher SPL. However, this innovation was patented by David Royer in 1999. The RSM-5 initially shared this design, but was subsequently changed to a symmetrical design, and it seems likely the RSM-3 will follow suit.

The mic ships with a padded nylon bag, a wooden storage box, and a shockmount. It carries a warranty that expires upon receipt — as the User Guide puts it, “the warranty on this microphone does not extend beyond an initial inspection, since these microphones can be so easy damaged during handling and use.”

The MSRP was $359.95 when the mic was introduced, Street prices as of Summer, 2008 are quite a bit lower, $250-$270.

The Nady RSM-3 is also known as: RSM3.

The mic was released in 2005.
