The CM- 67is a large dual diaphragm tube condenser microphone based on the famous Neumann U67design and specifications. The Advanced Audio CM-67 features a very accurate 1.07” capsule with 6 micron German mylar diaphragms. This capsule has a frequency response within 2 db of the Neumann K67 mylar capsules used in tube microphones. The 6072a circuit has been upgraded by us to provide a lower output impedance with slightly more headroom than the circuit used in the original U67 yet this circuit it able to provide a faster transient response when driving the authentic BV11 dual bobbin output transformer wound to the original Telefunken blueprints. The BV11output transformer will deliver +18dbm with less than 1% distortion and respond down to 20hz.   Specifications: • 1.07” dual diaphragm • 6 micron German Mylar • 25hz to 20khz + or – 3db • 3-selectable pick-up patterns • -17db(A weight) noise • <200 ohm Impedance • .5% distortion @ 125db • Class “A” 6072a tube circuit • BV11 output transformer • Robust shock-mount • Aluminum road case     CM-67: $765.00 6 micron German mylar capsule, including shipping.
