DIY Audio Components RM-5
Bidirectional Ribbon Microphone
The RM-5 is a passive ribbon microphone with a figure-of-8 polar pattern.
Although simple in appearance, it is built by hand using high-quality components and a level of attention somewhat uncommon in microphones at this price point.
The ribbon motor is DIYAC’s RE-154, available separately to do-it-yourself ribbon mic enthusiasts. Its Neodymium magnets surround a 2-inch, 2.5-micron corrugated ribbon made of Japanese aluminum. The assembly is held together in a chassis made of polycarbonate plastic.
The motors are hand-built and tuned by DIYAC staff.
The mic’s output transformer is the Edcor RMX-1, a 1:37 design made in the US with 80% nickel-alloy laminations and high-grade insulated copper magnet wire. It was chosen following an extensive round of auditions against competitive models.
Through September 8, 2011, the RM-5 is available at introductory pricing of €199 (a 33% discount from MSRP).
