CardioidSE Electronics sE1a

Cardioid Pencil Condenser Microphone

The sE-1a is a low-cost, small-diaphragm Cardioid FET condenser microphone.

It shipped with a Cardioid capsule that could be removed. The sE1a head amp accepts capsules made for the sE2a, which reportedly used an identical head amp.

The Cardioid capsule has a 0.75'' (19mm) diaphragm.

Reviews are generally positive, although often cite the “value for the money” argument, which has lost some of its impact since the reviews were written (3+ years ago).

This mic is available singly, or in a factory matched stereo pair. The pair is bundled with a special case and a stereo bar for $499 (MSRP, late 2011).

The SE Electronics sE1a is also known as: 1A, SE-1A, SE1, SE-1.

The mic was released in 2004.
