Advanced Audio CM87se FET Condenser Microphone

The Advanced Audio CM87SE came about in response to an inquiry regarding using the CM87 close on drums in a “Glynn Johns” type set-up where the microphones are less than 2 ft from the closest drum or cymbal source. To accomplish this, Advanced Audio fit a more complex output transformer with dual windings and bi-metal lamination's that is able to handle more easily the fast rising drum transients when placed close to the drums.

The CM87SE in all other aspects is identical to the CM87. It is a large diaphragm FET three pattern condenser microphone that features a double-diaphragm/double back-plate 6-micron AK67 type capsule and Class “A” transformer coupled amplifier design. It is well suited for recording vocals or instruments in any studio or live application and able to capture the drums at very close distances.

The CM87SE is built to a very high standard and offers a remarkably full yet well-defined and ultra-clean sound. Advanced fit the more sophisticated output transformer in their shop, and the CM87SE goes through a more rigorous level of QC. Like the CM87, the CM87SE can be configured as either omni, cardioid, or figure-eight via a front mounted metal toggle switch. The CM87 has 14 dB more headroom than traditional FET/transformer circuits.
