The AT4021\u2019s cardioid pickup pattern helps to improve isolation of your sound source, and an onboard switch lets you choose between a flat response, or a rolled-off response at 80Hz, to eliminate low-frequency rumble. It\u2019s a good choice for miking acoustic guitars or for using as a drum overhead microphone. Essential accessories, including a stand clamp, a windscreen, and a protective carrying case, are included with the Audio-Technica AT4021 small-diaphragm condenser microphone.<\/p>\n<p><b>Audio-Technica AT4021 Small-diaphragm Condenser Microphone at a Glance:<\/b><\/p>\n<ul>\n<li>Studio and stage-worthy microphone, great for acoustic guitar and drums<\/li>\n<li>10dB pad and 80Hz highpass filter, for tailoring the AT4021 to the source<\/li>\n<\/ul>\n<p><b>Studio and stage-worthy microphone, great for acoustic guitar and drums<\/b><br \/>\nA member of Audio-Technica\u2019s rugged 40-series microphones, the AT4021 is a worthy choice for both stage- and studio-miking needs. It features a cardioid pickup pattern for excellent sonic isolation from other instruments, and its low self-noise keeps it usable in critical studio applications. You\u2019ll find the AT4021 to be an especially good choice for miking acoustic guitars, as well as for using as drum overhead microphones, in a pair.<\/p>\n<p><b>10dB pad and 80Hz highpass filter, for tailoring the AT4021 to the source<\/b><br \/>\nThe Audio-Technica AT4021 lets you tailor its response to whatever source you happen to be miking. Already, it features high SPL handling \u2013 146dB \u2013 and, with its 10dB pad engaged, you can comfortably handle sources up to 156dB SPL, without distortion. This makes the AT4021 especially useful in drum-miking situations. What\u2019s more, an onboard highpass filter at 80Hz helps to take out the muddy low frequencies, giving you a cleaner sound when recording more articulate, high-frequency-emphasized instruments.<\/p>\n<p><b>Audio-Technica AT4021 Small-diaphragm Condenser Microphone Features:<\/b><\/p>\n<ul>\n<li>Polar pickup pattern: Cardioid<\/li>\n<li>Frequency Response: 20Hz-20kHz<\/li>\n<li>Low-frequency Roll-off: 80Hz, 12dB\/octave<\/li>\n<li>Open Circuit Sensitivity: -34dB (19.9mV) re 1V at 1 Pa<\/li>\n<li>Impedance: 250 ohms<\/li>\n<li>Maximum SPL: 146dB SPL, 1 kHz at 1% T.H.D.;
