The Ceiling mic data sheet seems to imply that the Group 500 can connect up to 4 ceiling mic arrays but in my understanding it is only 2. Is this then only acheivable by integrating with Soundstucture C12?
The GS 500 and 700 had the supported microphone arrays, ceiling or tabletop, changed to a total of 4 in the 4.2 release of software in 12/2014. This was a result of the need for multiple microphone arrays to support the Acoustic Fence technology.
If you review the installation sheet of the product it will indicate the support of the 4 microphone arrays.
