For conferences, meetings and concerts, the ME-30W conference kit captures all sounds in stereo. This professional solution designed by Olympus includes two omnidirectional microphones. The conference kit is ideal for use with DS-30, DS-40, or DS-50. With 360° coverage, you won't miss any words. The left and right input, whose frequency response is 20Hz to 20,000Hz, can be mounted on legs included in the kit. To optimize the recording, it is best to place the microphones at 5 m intervals. The ME-30W kit is compatible with digital voice recorders. The kit includes a mains power supply, and a protective case.
