Kansas City - Sep 13, 2007 - Avlex is now shipping the the Superlux R102 aluminum ribbon microphone. The mic features the sensitivity of a condenser microphone, but with the frequency response and transient response characteristic of a ribbon microphone. The mic includes a field-replaceable modular ribbon assembly.

The R102's active aluminum ribbon consists of two parts: an electro-magnetic transducer and an impedance converting circuit. The electro-magnetic transducer applies a magnetic circuit field while the 2.5 micron-thick aluminum alloy ribbon is suspended between two poles and vibrates in synchronization with the incoming acoustical energy. The low ribbon mass allows the mic to provide a rapid transient response. The frequency response ranges from 20Hz to 15kHz with a figure-8 polar pattern.
