- ideal for use in boardrooms, conference facilities, courtrooms, teleconferencing
- optimized to boost speech intelligibility
- works with a wide range of connection adapters and power supplies
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 ft) cable.
The BLM4060 can be very easily placed in essentially any position on the surface, even close to the edge (See graphs & more). 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 adapter.
