The Altec Lansing AL50ND is a cardioid dynamic microphone utilizing a revolutionary neodymium alloy magnet with four times the power potential of conventional microphone magnets. With a computer-optimized design, the AL50ND magnet structure provides unprecedented sensitivity while the more uniform magnetic field lowers distortion during peak sound pressure levels.
The AL50ND microphone utilizes an advanced vibration-isolation material. This material is a low-Q elastomeric polymer with extremely high energy absorbing properties. The result is a substantial reduction in handling and cable transmission
noise.
The AL50ND has an extended high-frequencyresponse with an open, transparent sound quality due to a large diaphragm that contains 50 percent more surface area than conventional designs.
The AL50ND features a die-cast zinc case, with rugged grille screen that retains its shape for years. The dynamic element will provide years of reliable operation, even in humidity and temperature extremes. The microphone includes an "on/off' switch that locks in the "on" position if desired.
The uniform cardioid polar pattern of the AL50ND insures superior gain-before-feedback in live applications and better isolation in the studioat all frequencies-compared with other directional microphones with widely varying polar characteristics.
