With low noise being a top priority of the NT1-A, its 1" gold-sputtered capsule is internally shock-mounted to further isolate it from handling and vibration noise. Additionally, the mic's cardioid polar pattern naturally rejects a good deal of sound behind it, which yields less background noise and room sound than other patterns such as omnidirectional and figure-8. Since it can run on 24 or 48 VDC phantom power, the NT1-A can be used with a variety of professional and entry-level XLR mic preamps.
Large-Diaphragm True Condenser
This true condenser (externally biased) features a 1" gold-sputtered diaphragm that provides a broad frequency response, wide dynamic range, and excellent signal-to-noise ratio.
Cardioid Polar Pattern
The cardioid polar pattern of the NT1-A effectively minimizes off-axis noises such as room ambience, monitor bleed, and instruments behind the mic.
Transformerless Output
The transformerless output electronics result in an ultralow-noise output (just 5 dBA) while maintaining maximum signal gain.
48V Phantom Power
The NT1-A operates reliably on 24 or 48 VDC phantom power, which can be supplied via most XLR-connected mic preamps, mixer channels, or audio interfaces.
Accessory Package
The accessory package includes a studio-grade shockmount with an integrated pop filter, a premium 20' XLR mic cable, a dust cover, and a downloadable instructional video packed with recording tips.
