From Josephson Engineering:
The C706 is a versatile studio microphone using a variant of the large diameter, dual-diaphragm cardioid capsule and the same discrete FET cascode input circuit and active balanced transformerless output circuit of the C716. The capsule, using 5 micron gold-metallized diaphragms and precision machined internal surfaces, provides a smooth and extended high end, detailed midrange and the controlled proximity effect characteristic of dual-diaphragm mics.The C706 is not only great for vocals, it’s also excellent for instrument and ensemble pickup, and works well with a variety of preamps and input stages, due to its low output impedance.
The housing is made of case-hardened steel with a unique offset grille support structure that greatly reduces internal reflections, avoiding the harshness of many large-diaphragm mics. The entire capsule assembly is internally shockmounted, so the microphone can be attached directly to a stand through its yoke mount. The black finish from the hardening process is very rugged for long life in studio and stage applications.
