Crown LM301 Podium Microphone

CROWN LM301 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.

No matter the situation, the elegant LM-300A and LM-301A can meet the need. Both of these silent-operating goosenecks provide the same superb supercardioid performance and noise rejection. Explosive breath sounds are effectively reduced with the supplied foam 2-Stage Popfilter, while a low-cut switch further reduces breath pops. The LM-300A and LM-300AL (extended) plug directly to an XLR female panel connector, while the LM-301A features an in-line tubular electronics module. The microphone screws onto a standard 5/8"-27 thread. For situations requiring even more isolation from noise, the LM-SM shock mount is supplied at no charge.
