For larger or more difficult rooms Rally Bar supports up to 3 Rally Mic pods. Rally Bar also supports the Mic Pod Hub, which counts as one of the Mic Pods (so, for example, you can have 2 Rally Mic Pods and 1 Mic Pod Hub).  If you plan on using the Rally Mic Pods, you will also need to use the Rally Mic Extension Cable - a 10 meter cable that connects to the back of Rally Bar. You can use up to 2 of these cables with Rally Bar.
