Crown LM201 SUPERCARDIOID CONDENSER LECTERN MICROPHONE

CROWN LM201 Details ^top

The Crown lectern microphone (LM) series offers high gain-before-feedback, smooth articulate sound, and superior noise rejection in a slim, elegant package.

The microphones' simple installation and stylish good looks will complement any lectern application, from the corporate boardroom to the bully pulpit. Their durable, high-quality design will give you consistent, reliable performance for years to come.

Featuring a supercardioid element, these microphones virtually eliminate the potential for undesirable noise to enter the system, even at high gain levels. Their performance is further enhanced by specially designed pop filters that effectively reduce explosive breath sounds. All this, combined with
their silent-operating gooseneck and shock mount designs, makes the LM Series microphones easy
to position and use.

Designed for the most demanding installations, these microphones are manufactured with top-quality materials and feature reinforced joints and connections. Each microphone is individually inspected and tested to ensure perfect performance out of the box.

The newest addition to the LM Series is the LM-201 microphone. Featuring a shock-mounted element and a rigid arm attached to a noiseless ball and socket, this microphone resists wear and tear, making it perfect for tougher applications such as churches, schools, city council chambers and state legislatures.

Crown LM-201 Microphone
Slim, rugged and unobtrusive, the LM-201 is the best choice for legislature, city council and other demanding lectern applications. Its internal shock mount reduces lectern thumps. A ball-and-socket joint combined with a rugged mic arm provides quiet, long-term operation. The LM-201's supercardioid pattern rejects background noise and reverb while improving gain-before-feedback. Outboard electronics attach to supply power to the condenser element, with the option of power by normal phantom power or miniature AC plug-in adapter.
