Creating multi-channel Room Combiners

The Room Combiner block in Audia/Nexia is a very powerful block for that room combining applications. However, by default this block provides only a single input and a single output per room. That works in the majority of cases, but what if your rooms are stereo? Or you have multiple signals that need to be combined/divided (like a separate speech and program signal for each room)? Depending on the number of rooms and their layout, there are two methods to perform room combining with multi-channel signals.

Using a single Room Combiner block

Start by adding a Room Combiner block to your design. In the initialization dialog, you would need to configure two identical layouts separated by a single column as shown here. In this particular case inputs 1&2 would be for room #1, inputs 3&5 for room #2 and inputs 4&6 for room #3.

To make this work from the control stand point, we need to be certain that we combined both sides at the same time. The easiest way to achieve this is using logic states connected to the appropriate nodes on the room combiner. The diagram below shows the entire circuit:

By extending the same concept, you can create a more complex system with more rooms and/or more channels per room.

Using multiple Room Combiner blocks

The same results as described above can be achieved by using multiple Room Combiner blocks. All of these will have the same room layout but each will be controlling a different channel (i.e. one Room Combiner for the left channel and another for the right channel). The diagram bellow shows an alternate solution for the scenario explained above using this method

Each Logic State block is connected to the same channel on both Room Combiner blocks, to ensure that the wall states in both Room Combiner blocks are always the same. As with the above case, you can have more channels by adding more Room Combiners.
