The Shure SM27 Cardioid Condenser Microphone is a cost-effective large diaphragm solution for capturing vocals and instruments in project studio recording applications. Among the SM27's features is a cardioid polar pattern, -15dB pad switch and 3-position low-cut filter switch.

The cardioid capsule effectively minimizes off-axis noise while reducing feedback and a -15dB pad maximizes headroom, reducing peak noise and distortion caused by transient (peaking) audio signals. The SM27's 3-position low-cut filter switch minimizes low-frequency noise and proximity effect. Overall the SM27 is a modestly priced microphone that is sure to please musicians, vocalists, and experienced audio engineers alike.

      Comments about Shure SM27 Large Diaphragm Cardioid Condenser Microphone:

      I researched many lower cost, large diaphragm condensers and heard Ken Callait recommend the SM27. I planned to purchase it myself, but my wife bought it for me as a Christmas gift, and I've already had the chance to use it on a variety of sources.

      It is clear and pristine sounding. It works very well on percussion elements, acoustic guitars, and works well for certain types of vocals. I'd find it a little too clean and "pretty" sounding for rock vocals or anything where an indie vibe is the aim, but if clarity and pure translation are what you want, this mic really delivers.

      The packaging is nice (I got the version with the shockmount and velveteen case), and it's obviously of solid build quality. Well worth the price tag.
