CM1084

Advanced Audio’s CM1084 is one of the most versatile small diaphragm condenser microphones available. The mic was inspired by the sought after vintage KM84 and the Calrec 1000 series SDC’s which were used in the R&D of the 1084. Advanced Audio Microphones worked very closely with UK engineer Niall John Acott to develop a mic that not only worked in large orchestral sessions, but equally well on sources in a rock or jazz session. The final shootout, done at Angel studios, London, under the supervision of Gary Thomas locked the mic in as a serious competitor in SDC microphones.

Circuit

The CM1084’s uses a very clean Class A fet 2 stage amplifier circuit coupled to a custom wound 2:1 transformer. The addition of a vintage setting limits the bandwidth to emulate the tight, flatter response of a vintage KM84. However, the circuit provides 14dB more headroom. The bright setting allows the full dynamics and natural rise. The mic features a -10dB PAD and a 75hz/150Hz low-frequency roll off.

Capsule

The CM1084 comes with 3 - 22mm capsules of your choice. Additional capsules can be purchased for $50 each. The capsules are all skinned with 6 micron Mylar. To change, they simply thread on or off of the mic. Available are an Omni, cardioid, wide cardioid and super cardioid capsule all with the very low profile design similar to the KM84. Also offered is the more rugged cardioid with the C451 type head grill.

Summary

The ability to switch from a vintage and a bright setting as well as the option of 5 different capsules means this little workhorse will perform under any situation. 

The CM1084 is very useful for recording high-transient studio instruments such as drums, percussion, or piano. With the low profile cardioid and the vintage setting the CM1084 does a magnificent job over strings. With the bright switch engaged, it brings life to an acoustic guitar that makes it sit very nicely in a mix.

We also offer the CM1084 as a matched pair with a stereo bar and wooden box to hold both mics.
