New Cardioid Condenser


Audio-Technica has introduced the AT2021 Cardioid Condenser Microphone. Here's what they have to say about it..
Ideal for home studio and live applications, the low-profile AT2021 offers an extended frequency response, high maximum SPL and wide dynamic range. The microphone's condenser design provides studio-quality performance for vocal and instrument applications, and is outstanding for acoustic guitar, overheads, piano and group vocals. The AT2021 is also available packaged with the acclaimed AT2020 in the AT2041SP Studio Pack.
The AT2021 captures smooth, natural sonic characteristics of the audio source, and the low-mass element provides excellent transient response. Corrosion-resistant contacts from the microphone's gold-plated XLRM-type connector, in addition to the mic's rugged design and construction, ensure consistent, reliable performance and durability for the user. The unit's cardioid polar pattern rejects pickup of sounds from the sides and rear, improving isolation of the desired sound source.
