The ADX51 is a professional pre-polarized condenser microphone engineered for high-fidelity stage, studio, and broadcast applications. Featuring a uniformly controlled cardioid polar pattern, it effectively isolates the target sound source while minimizing peripheral stage noise. A 14 mm gold vapor diaphragm ensures a clear and accurate frequency response across a wide 40 Hz to 18 kHz range. Integrated switches for a -10 dB pad and a 150 Hz bass roll-off filter allow for precise control in diverse miking environments. The precision machined brass body is finished with a durable black E-coat to withstand the rigors of professional touring. Gold-plated XLR connectors provide superior conductivity and reliable signal transmission for critical recording sessions. This versatile instrument microphone excels at both close miking and distance applications for acoustic instruments and overheads.
