Connection of up to six units* enables high-quality recording with reduced noise, even for meetings with large numbers of people. Connecting units with 2-metre-long cords enable recording in which each speaker's voice in a large conference room is equally easy to hear.

^{*In the case of an Olympus digital recorder with stereo microphone jack specifications, you can connect three units to each of the L and R channels. Up to three units can be connected to a recorder with mono microphone jack specifications. If you connect more units, the sensitivity or S/N ratio may deteriorate, or the recording may fail.}
