Product Description
The CM-47SE is a large dual diaphragm, multi-pattern, tube condenser microphone based on the famous Neumann U-47 design and specifications. The SE features the highly desirable Peluso Capsule.
The Advanced Audio CM-47SE features a very accurate yet smooth 35mm capsule with 6 micron thick German mylar diaphragms. This capsule has a frequency response within 2 db of the Neumann K47 mylar capsules used in all U47 tube microphones built after 1961.
The 6072 tube circuit has an optimized 2-stage class “A” design that provides a lower output impedance with more headroom than the circuit used in the original U47. The lower output impedance provides a fast damping factor when driving the BV8 type transformer.
This dual bobbin output transformer with it hum bucking feature and our optimized circuit will deliver +20dbu with less than 1% distortion. The output transformer is driven with a 2.2 ufd metal film capacitor to take advantage of the transformers response down to 10hz.
Selected 6072a tubes are some of the quietest tubes made and much less susceptible to “microphonics” than the metal clad vf14 tubes used in the original U47 tube microphone.
Specifications:
• 1.07” dual diaphragm
• 6 micron German Mylar
• 25hz to 20khz + or – 3db
• 9-selectable pick-up patterns
• -17db(A weight) noise
• <200 ohm Impedance
• .5% distortion @ 125db
• Class “A” 6072 tube circuit
• BV8 type output transformer
• Robust shock-mount
