Ideal for professional recording and critical applications in broadcast, this 40 Series cardioid condenser microphone consists of the AT4900a-48 body with the AT4051a-EL cardioid element. This versatile studio performer may be used with confidence in a wide variety of professional miking applications, even under the stringent demands of modern digital recording systems. Featuring direct-coupled balanced outputs for clean signals in high-output conditions, the microphone is totally free of the distortion associated with conventional transformer-coupled outputs. And its fast response to transients contributes to the open, transparent reproduction of even the most difficult-to-capture instruments.

• Direct-coupled, balanced output ensures a clean signal even in high-output conditions
  
• Exceptionally low self-noise, very high output and fast transient response
  
• Accepts optional interchangeable capsules: AT4049a-EL (omnidirectional) and AT4053a-EL (hypercardioid)
  
• Switchable 80 Hz hi-pass filter
  
• Turned-brass microphone housing with black chrome plating
  
• The AT4051a consists of two modular subassemblies: an AT4900a-48 body and an AT4051a-EL head capsule (both available separately)
