BLM4060 Boundary Layer Microphone description:

The DPA BLM4060 Boundary Layer Microphone. Superb clarity and speech intelligibility.

The DPA BLM4060 Boundary Layer Microphone is ideal for use in boardrooms, conference facilities, courtrooms, teleconferencing and other applications where excellent vocal pickup is required. The BLM4060 is a transducer designed to work under optimum conditions when placed on a tabletop, but it also performs well on any other hard, flat surface that reflects sound. The microphone element is a prepolarized omnidirectional miniature condenser microphone with a 5.4 mm (0.2 in) vertical diaphragm specially designed for maximum performance. The microphone body consists of a centre rubber disc that holds the microphone element mounted in an elegant stainless steel base. The BLM4060 has a 3 m (10 in) cable. The BLM4060 can be very easily placed in essentially any position on the surface, even close to the edge. Users will benefit from the special characteristics of the surrounding sound field on which the BLM4060 is mounted: a 6 dB gain of direct sound and only 3 dB gain of the diffuse sound. Therefore, the sound captured has both a greater clarity - especially at high frequencies - and speech intelligibility compared to sound captured above the surface. A wide range of connection adapters and power supplies makes it possible to use the BLM4060 with any microphone input. It is delivered with a DAD6001-BC (MicroDot to 3-pin XLR) adapter for powering via standard P48 phantom power.
