Industry-standard mic renowned for sonic accuracy in stage and studio performances.

The Shure SM81 condenser microphone is a highly sensitive yet durable mic ideal for any studio. With its wide frequency response and low self-noise, the SM81 captures vocals and acoustic instruments with stunning clarity and nuance. Its cardioid polar pattern focuses on sound sources directly in front of the mic, reducing unwanted ambient noise.

Pristine Audio Quality for Vocals and Acoustics

The SM81's extended frequency range of 20Hz to 20,000Hz captures the nuances of any performance. Its low self-noise means no hiss or hum to distract from the audio. The SM81's condenser capsule is highly sensitive, allowing it to pick up the subtle details of vocals, acoustic guitars, pianos and percussion. The mic's flat frequency response provides an uncolored sound, letting the true tone of the instrument or voice shine through.

Versatile Polar Pattern for Focused or Ambient Recording

With the flip of a switch, you can change the SM81 from a cardioid to omnidirectional polar pattern. In cardioid mode, the mic focuses on sound sources directly in front of it, reducing ambient room noise. This focused pickup is ideal for recording vocals or solo acoustic instruments. In omnidirectional mode, the mic picks up sound evenly from all directions, capturing more of the ambient room reverberation. Omnidirectional mode works well for ensemble recordings where blending multiple audio sources is desired.

Roadworthy Design for Studio and Live Use

Despite its sensitivity, the SM81 is a rugged mic able to withstand the rigors of studio and live use. Its sturdy metal chassis protects the condenser capsule from damage. The SM81 operates on standard 48V phantom power and performs reliably in a range of temperatures and humidity levels. An included swivel mount, windscreen and carrying case provide flexibility in mic placement and transportation. The SM81's durable build and included accessories make it suitable for studio and live-sound applications.

Additional Accessories for Optimized Performance

Optional accessories like shockmounts, pop filters and boom arms (all sold separately) allow you to optimize the SM81 for your needs. A shockmount reduces vibration and handling noise for the clearest capture of sound. Pop filters prevent plosives from distorting your recordings. Boom arms provide flexibility in mic positioning, allowing you to capture sound from multiple angles and heights. With these additional tools, you can customize the SM81 to suit any recording scenario.
