When multiple Conference Room Routers (CRRs) are added to a Room Combine Group (RCGroup), the audio signals needed to combine those rooms are automatically routed between the CRRs. Depending on which DSP contains each CRR, the automatic routing may be accomplished using Audio Routes, Dante® routes, or a combination of both.
If two or more CRRs in the same DSP device are added to an RCGroup, the automatic routing of audio between those CRRs will be accomplished using Audio Routes. An Audio Route may be thought of as an invisible wire. All the audio signals that enter an Audio Route input will be available at any Audio Route output associated with that Audio Route input and there may be multiple Audio Route output objects associated with each Audio Route input object.
Audio Route output objects always have the same name as their associated Audio Route input object. Renaming any Audio Route will change the name of the Audio Route input and all associated Audio Route outputs. When Audio Routes are created for the RC Group, each Audio Route will be named “From Rm#”, with “#” being replaced by the number of that room within the RCGroup. This allows easy identification and verification of signal placement.
Audio Routes are limited to routing audio with a single device, but a project may contain CRRs located in different DSP devices. When an RCGroup needs to route audio between devices, Dante routes are used automatically. The RCGroup will place the Dante input and output objects as needed and create the appropriate Dante subscriptions to ensure that the correct audio is delivered to each CRR.
If a project contains multiple CRRs with some CRRs in the same device and other CRRs in different devices, the RC Group will automatically use Audio Routes for signals being routed within the same chassis and Dante routes for signals passing between chassis.
