Multi-Pattern Tube Condenser Microphone
The Superlux CMH8D is a dual-pattern large-diaphragm tube condenser.
As part of the CMH8 series, it uses a one-inch, 3 micron true condenser capsule and identical exterior metalwork. The circuitry uses a hard-wired (not socketed) Nuvistor-type tube, with a transformer-coupled output.
A two-position polar pattern switch provides Cardioid or Omnidirectional patterns. Two other switches independently enable a high-pass filter (200Hz) or -10dB attenuation pad.

I tested the CMH8D valve mic alongside my Rode NTK […] The CMH8D sounds as warm and exciting as you’d hope a valve model would, with a slightly throaty and very much ‘in-your-face’ character. My Rode is smoother and less ‘pumped’ sounding, with a slightly more sophisticated quality, to these ears, but I really did like the Superlux for its more aggressive edge.
The CMH8D includes its dedicated power supply (Superlux p/n PS1), HM8 adapter, YA2 threaded adapter, S65 windscreen, HM7C shock mount, and the necessary cables.
The Superlux CMH8D is also known as: CM-H8D.
