The ADX51 is a professional, pre-polarized condenser microphone for stage, studio and broadcast applications. The ADX51 is clear sounding, accurate in response and handles both close and distance miking for various acoustic instruments. Designed with a uniformly controlled cardioid polar pattern, the ADX51 captures the acoustics of the instrument being miked while isolating it from other instruments. The ADX51 features a 14 mm gold vapor diaphragm and a -10 dB pad and bass roll-off filter. The ADX51 includes a tension-fit heavy duty nylon mic clip (DCLIP) , external foam windscreen (W-81), and zippered carrying pouch (P1).
