Nady RSM-4

Bidirectional Ribbon Microphone

The RSM-4 is a passive ribbon mic of Chinese origin.

Nady’s specifications state that this mic uses a 6-micron aluminum ribbon. If true, this would be a relatively heavy element; similar mics from competing manufacturers use lighter-gauge aluminum. 6-micron aluminum would tend to be more durable than lighter material.

The mic ships with a leatherette bag and a mic clip. 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.”

At its introduction, the RSM-4 had an MSRP of $399.95. The price has since fallen. See current “street” prices below.

The Nady RSM-4 is also known as: RSM4.

The mic was released in 2005.
