Shure Beta 91

Description

The Beta 91 is a boundary mic intended for use inside a kick drum. It uses the mic capsules from the Beta 98; the RPM108 cardioid capsule provides a half-cardioid response in the Beta 91. Presumably the RPM110 provides a half-supercardioid response.

The case is metal (zinc alloy). The grille is steel, finished in matte black. It ships with an inline preamplifier (p/n RPM626), soft case and a 15' detachable mic cable.

The jack on the mic case appears to be a 4-pin TA4M; the supplied cable is a TA4F to TA4F (mini-XLR female). The RPM626 preamp has a TA4M on one side and XLR on the other, for use with standard mic cables.

The Shure Beta 91 is also known as: Beta91, Beta 91.
