The Josephson C716 is part of the Series Seven range
of large diaphragm side-address microphones. It uses
large dual-diaphragm capsule similar to the one used
in the C700 microphones, with a fixed cardioid
directional pattern.
A unique feature of the C716 is its patented open-cell
metal foam grille. Unlike traditional microphone
housings made of perforated metal or wire screen with
reflective metal support structures, this highly open
material protects the capsule mechanically, provides
electrical shielding and some pop and wind screening
without needing any additional support structure. A
fine, acoustically transparent screen inside the grille
helps protect the capsule from breath moisture when
the C716 is used as a vocal mic. We were able to
avoid using a traditional basket support structure
because the foam itself is a tough self-supporting
aluminum alloy. It’s a highly open structure so that
internal reflections are negligible, while the metal still
provides full protection for the capsule. Traditional
designs incorporate rings and bars to support the
basket material, leading to the reflections shown in
the left illustration on the next page.
