The ADX12 and ADX18 are professional miniature gooseneck condenser microphones designed for applications such as podium, presentation, meetings and teleconferencing. Known for their clarity, excellent sound quality and ease of operation, the ADX12/18 will accurately capture and reproduce vocals from a comfortable distance. The ADX12/18 are characterized with a uniformly controlled cardioid polar pattern, helping to isolate the speaker from other ambient noise in the room or on the stage. The ADX12/18 mics are also available in a hypercardioid polar pattern (models ADX12HC and ADX18HC) for tighter pick-up control. With a wide frequency range of 40 Hz - 18 kHz, the ADX12/18 provide natural sound with exceptional transient response. The ADX12/18 mics are equipped with an integrated preamp circuitry built into the base of the XLR and may be mounted permanently via the supplied fange mount or with an optional base with an internal shock mount (SMT1218R). The mics may also be used on a standard mic stand or in conjunction with the Audix ATS-10 table stand with lighted on-of switch. Manufactured with very high standards and tight tolerances, the ADX12/18 features a machined brass body, feld replaceable capsule and a variety of optional accessories. The ADX12/18 operate on phantom power of 18 - 52 Volts and are available in non-refective black matte fnish.
