Rode NT1A Studio Condenser Microphone Low distortion. Higher SPL capability. The Anniversary Model NT1-A is a complete redesign of the now legendary NT1 classic studio microphone. From the new nickel-plated body to the state-of-the-art surface mount electronic circuitry, the NT1-A will leave you asking ”how can RODE offer a microphone that sounds this good, for so little money?” It takes advantage of the huge RODE investment in advanced large scale manufacturing allowing premium performance, durability, consistency, and construction at a price that anyone can afford. With a self-noise figure of only 5.5 dBA, the NT1-A is one of the lowest noise studio mics in the world — regardless of cost. Unrivaled low distortion, higher SPL capability, and extended dynamic range make it well suited for even the most demanding digital recording applications. Certified Matching Pair Matched pair has been acoustically matched for equal sensitivity from each mic. Includes certificate of testing.
