The Shure MX391-O uses an omnidirectional condenser capsule, picking up sound evenly from all directions across the table. This makes it a good fit for round-table discussions where speakers are seated on multiple sides of the microphone.
Yes. Like the rest of the Microflex MX391 boundary range, the MX391-O uses an interchangeable condenser cartridge, so the omnidirectional capsule can later be swapped for a cardioid or supercardioid capsule from the same series if coverage needs change.
The Shure MX391-O measures 19.05 x 53.04 x 79.4 mm (H x W x L) and weighs 126 g (4.44 oz), a low-profile black housing designed to sit unobtrusively on a boardroom or altar table.
The MX391-O has a 12.14 foot (3.7 m) cable on its preamp terminating in a standard 3-pin male XLR connector, and it draws 11 to 52 Vdc phantom power through that same connection.
The Shure MX391-O has a sensitivity of -22 dBV/Pa and handles up to 111 dB SPL before distortion, with a 96.2 dB dynamic range and a flat 50 Hz to 17 kHz frequency response tailored for natural speech pickup.
