3200s don't have EBA processing in any firmware version. The EBA Command just enables additional latency to keep them time - aligned with speakers that do have EBA processing. If you have a DSW then the DSW will do EBA and the 3200s will keep in time with it. If you don't have a DSW then all you get is the delay.

The presence / absence of EBA as an option in the SpeakerLink menu of the AC200 is a function of the firmware version of the AC200. Whether anything happens in the speakers when you send it is a function of the speaker firmware.
