The CM800T is a large diaphragm, 3-pattern tube condenser microphone producing the presence lift heard from the original C800G. A favourite by many Hip Hop and Rap artists. 




Double-sided, dual back-plate 32mm K67 type capsule with a HF rise similar to the original capsule utilized in the c800g.




The circuit is designed around a military spec'd GE/JAN 5654W tube which is configured the same way as the C800G circuit that used a 6AU6a tube.

We first saw the 6AU6a tube in mantle radios sold in the early 60’s and find the 5654W to be of a higher quality and have more consistent build than the "pedestrian" 6AU6a.  The 5654w tube also generate less heat than the 6AU6a and no cooling device is required.

The combination of the K67 capsule response coupled to a pentode tube configured as a triode with no de-emphasis; provides the bright and articulate sound of the C800g.

We also added a -10db pad for close miking of drums, percussion and instrument amps.

This gives the CM800T >6db more headroom than the C800G.

There is also a 100hz switchable rumble (HP filter) accessible at the rear of the microphone.

We were were also able to add a Fig 8 option which the C800g did not have while still keeping the passive cardiod polarization of the original C800g.

 All components in the CM800T are of higher quality and have better tolerances than those components used in the 1992 designed C800G.
