SHURE SM5B

SHURE SM5B

The SM5B has been specifically designed to minimize boom microphone problems in television and motion pic­ture sound stage and location recording. It was pains­takingly developed to provide extremely high reproduc­tion quality and great flexibility of application. A hum-bucking coil assures low susceptibility to electrical hum and allows the SM5B to be used in extreme hum fields.

More Information

Features

  • Mechanical suspension: Two-stage mechanical isolation for any boom applica­tion. Suspension elements internal to windscreen prevent wind noise generation in suspen­sion assembly; external shock assembly prevents trans­mission of boom or stand noise to microphone.
  • Integral windscreen: Very effective in outdoor locations and for fast boom swings.
  • Frequency response: Wide range, smooth and natural, specially tailored for dialog and vocal pickup with excel­lent presence, yet well-suited to scoring assignments.
  • Hum-bucking coil: Assures low susceptibility to elec­trical hum, permits use in extreme hum fields.
  • Directivity: Cardioid, symmetrical about axis and excep­tionally uniform with frequency. Minimizes sound color­ation due to off-axis pickup. Provides effective rejection of background noise and excellent reach.
  • Rugged and dependable under all operating conditions. Cartridge and isolation assembly protected by outer wind­screens and steel reinforcing rods.

Because of its unusual mechanical construction and per­formance characteristics, the SM5B may be used to ad­vantage in many applications where boom operation is not practical: for example, with an accessory desk stand for outdoor sports and other difficult remote pickups.
