Ganging DUET Executive units together The maximum recommended range of operation for a single DUET is 3 meters (10’). Ganging several DUETs together provides coverage for a larger conference room, classroom, courtroom, etc. There is no limit to the number of DUET Executives that can be ganged, so any size conference room can be addressed. We recommend that the maximum spacing between any two DUETs in such an arrangement should not exceed 2 meters (10’) in order to guarantee good audio pickup. When ganged together, each of the DUET's microphone and loudspeaker are operational. The user can control the volume level of each of the DUET Executives separately. The effect obtained is distributed microphone pickup and distributed loudspeakers. |
