Elegant yet rugged the high-output SM63 series of dynamic omnidirectional microphones are designed for professional applications where performance and appearance are critical. The SM63LB iz ideal for remote interviews and other situations where longer microphone is desirable. The smooth wide frequency response of the SM63 is tailored for optimum speech intelligibility and includes a controlled low-frequency rolloff for reduced pick-up of stand and wind noise. A built-in humbucking coil makes the microphones virtually immune to strong hum fields such as those produced by studio lighting.
