Sony is a leading provider of professional
lavalier microphones.
The ECM-50, Sony’s rst lavalier microphone released in 1969, was an epoch-making
product that achieved a perfect balance between compact size and excellent
performance. The ECM-50 led to the development of the broadcast-standard
ECM-30, a smaller and less expensive lavalier released a few years later.
More than four decades later, Sony is still a leader in the lavalier microphone market
with nine models and 21 variations, including the ECM-55 which is the successor of the
legendary ECM-50, and the ECM-44 which is the successor of the ECM-30.
Sony’s ECM-88 is a series of ultra-miniature, omni-directional lavalier microphones,
whose performance is highly acclaimed within broadcast, production, and theatrical
circles. The ECM-77 is also very well regarded, especially by broadcasters.
The ECM-66 is another top-of-the-line model with uni-directional directivity, which
provides good isolation and resistance to feedback.
Sony is also a leading manufacturer of digital wireless microphone systems*1.
Recently, the ECM-66, ECM-55, and ECM-44 series have been qualied for use with
digital wireless by enhancing the capsule shielding to reduce radio frequency
interference susceptibility, as well as the ECM-77 series*2. In addition to superb sound
quality, digital systems offer a number of advantages such as stable transmission and a
more exible channel plan.
Lavalier microphones from Sony are an ideal choice for virtually all quality-conscious
sound-gathering applications, including public address, ENG/EFP, studio, theater, and
use with musical instruments.
*1 The digital wireless microphone system is not available in some countries.
*2 Digital wireless system requires use of the /9X version lavalier microphones.
The ECM-77, ECM-66, ECM-55, and ECM-44 series have already been switched to the /9X version.
