The Audio2000'S S106A is a professional USB unidirectional dynamic microphone with built-in USB output and XLR output, one USB-XLR cable, and a hard PVC carrying case. A super efficient magnetic circuit design with a premium magnet element provides maximum output level for an improved signal-to-noise ratio for bass drum and sound reinforcement applications. Incorporated with an extremely light weight diaphragm, the low impedance capsule of the S106A inheres excellent transient responses and a wide frequency range with the results of a transparent presentation of sound amplification. Throughout the S106A's full frequency range, the cardioid pattern stays uniform and symmetrical to significantly cut off any feedback and off-axis coloration.
