Installation guide

NOTE: As base rooms and walls are arranged in the Room Combine property dialog, a unique
Room Processor is created for each base room combination (For example a room processor could
be created for room combination A, B, C, A+B, B+C, and A+B+C). The total number of Room
Processors in the configuration is calculated by adding together the Room Processors assigned to
each Room Combine block in the configuration. To prevent the creation of an excessive amount
of Room Processors in the configuration, additional walls and base rooms cannot be added to any
Room Combine blocks once the total number of Room Processors in the configuration exceeds
100. Depending on the layout of rooms and walls in a Room Combine block adding an additional
wall could result in the addition of anywhere from a couple of new Room Processors to well over
100. In the off chance the addition of a wall to a room combine layout is permitted but takes the
total number of room processors above 150 the configuration can no longer be applied to a HAL.
Next? Designate the inputs and outputs for each of your base rooms.
In reality, you would probably wire in your inputs and outputs before arranging your base rooms and
specifying which walls are movable—the process described above. But we wanted to be sure you under-
stood those key concepts before moving further into the room combine process. So we'll back up a bit
and return to the original Room Combine Processor block—the place where you specify how many base
rooms you have. On the following page is its picture again, with its key components clearly marked.
As you can see, each base room includes an Auto Mixer and a Mixer. You wire microphone input(s) to
the Auto Mixer and can also add one or more cascaded Auto Mixers (namely, the AM2 RAD). You
wire all other local inputs to the Mixer. You can add more inputs to both the Auto Mixer and the Mixer
by wiring to or clicking its <Add> node. Each base room also includes all the Distributed Program Bus
channels (if any have been configured)—as noted by the blue Distributed Program Bus rectangle at the
top of the block. In addition, each base room is automatically included as a paging zone in the
