Conference Room Combine Processor

How to Use

Included here is basic information for adding a Conference Room Combine Processor block to your system.

Adding the Block to Your System

Click the Processing tab to open the Processing Workspace.
In the palette area, click the DSP tab.
Expand the Conferencing category of blocks.
Click and drag the Room Combine: Conference block into your Processing Map.
Adjust the number of base rooms needed for your room combine (by deleting or adding rooms).
Wire each base room's inputs and outputs as appropriate.
(Optional) Create custom names for miscellaneous items on the block: the block name, input names, output names, and paging zone names.

Configuring the Block

Open the Conference Room Combine Processor block's properties by double-clicking the block or hovering and clicking the properties icon that appears in the upper right of the block's title bar. From here you can do the following:
- Configure the physical layout of the rooms, specify which common walls are movable or overflow, and provide end users with control over which walls are open or closed.
- Access the individual Room Processor blocks for each possible room, from which you can configure a wide variety of parameters, create additional control links specific to that room, and customize the room's main preset or add other presets. For more details, see Conference Room Processor Block.

Conference Room Combine Workflow

Configure the base rooms and add moveable wall

Add a Conference Room Combine processor to your configuration and add the required number of Base Rooms.
Open the Conference Room Combine dialog and click on the Layout and Control TAB.
- Drag available rooms onto the workspace and arrange
- Drag and place a moveable wall icon to the appropriate walls

Configure the Distributed Program Bus and Paging

If you have background music sources, add a Distributed Program Bus block and wire the required input sources. See Distributed Program Bus.
- This audio is available for selection in all Room Processor blocks. See Conference Room Processor Block.
Is Paging required?
- Add one or more PAGER1 blocks or Paging Station blocks. See PAGER1 Input Block (RAD) and Paging Station.
- Set up Paging Manager scenarios as required. See User Interface Reference.
- Each Room Processor supports the required Paging Zones. See Conferencing Room Processor Paging Zone Block

Wire base room inputs

Identify any local AV sources such as DVD, Blu-Ray, CD, computer etc.
- Wire these to Local AV Mixer inputs. See Conference Room Processor Local AV Mixer Block.
Are microphones required for local sound reinforcement?
- Wire these to Local Auto Mixer inputs. Conference Room Processor Local Auto Mixer Block.
Is a conference connection required?
- VoIP, POTs, Video Codec etc. See Switchboard.
- Wire to From Far End and To Far End nodes. See Conference Room Processor From Far End Mixer Block and Conference Room Processor To Far End Mixer Block.
What microphones are required for Far-end Auto Mixer inputs?
- Wire Far End Auto Mixer inputs via AEC blocks. See Conference Room Processor Far End Auto Mixer Block.
  note: There are eight AEC blocks per EXP7x expansion device. Typically, one AEC block is required for each far-end microphone. See EXP7x Device
  note: See an Introduction to Conferencing for details on where to place AEC blocks and how to determine the correct reference

Wire and set the audio mix for base room outputs

First, determine which outputs will be used for what purpose: local room, zone within the local room, recording, overflow, AEC reference, etc. See Introduction to Conferencing.
note: While labeled according to their typical function, Record Out, Room Out and Reference Out may be used in variety of ways. Any of these may be used in part or alone for the uses described above.
Set up the required base room mixes and wire each of the outputs. See Conference Room Processor Block, Conference Room Processor Room Matrix Mixer Block,and Introduction to Conferencing
note: Room Out is a unique mix of Local Auto Mixer, Local AV Mixer, Distributed Program Bus selection and From Far End signals. It also includes the Paging Zone signal
- Open the Room Matrix Mixer for each Base Room and set the required mix
  note: Reference Out mix always follows the Room Out mix minus the local microphone mix. This mix also includes the Paging Zone signal.
  note: Record Out is a unique mix of Local Auto Mixer, Local AV Mixer, Distributed Program Bus selection and From Far End. It does not include the Paging Zone signal
- Open the Room Matrix Mixer for each Base Room and set the required mix
Set up the mix for To Far End outputs
- Open the To Far End Mixer for each Room Processor and set the desired mix of Far End Auto Mixer, Distributed Program Bus selection and Local AV Mixer signals. See Conference Room Processor To Far End Mixer Block.
Do you require a reference for AEC blocks? See Introduction to Conferencing.
- Use Reference Out if you do not want microphones in the reference
- Use Room Out if you want microphones in the reference
What processing do room outputs require?
- Add EQ, Compression, etc as required and wire room outputs to the appropriate blocks
- Use multichannel and tracking blocks if room and reference need to mirror each other

Configure each Room Processor

You may want remote linking to vary depending on the Room Processor. For an example of changing which remotes are active and which ones need to track, see Control Linking in a Room Combine
Use custom Conference Room Processor presets to alter linking, input mixer participants, output mixes or processing external to the Room Processor as required. See What aspects of each room can I customize?

Layout & Control

After arranging the base rooms and designating which walls are movable, you need to provide end users with the ability to tell the system which walls are open and which are closed. There are two options available for providing end users with this control:

Link the Toggle controls (associated with each movable wall) to a DR, allowing the end user to specify if a certain wall is open or closed.
Link the Selector control (associated with the list of possible room combinations) to a DR, allowing the end user to select which room configuration is currently active. This approach has one limitation. If there are more than 20 possible room combinations, you cannot link the Selector control to a DR, as the DR would be incapable of displaying all of the options. In this case, it would be best to use the Toggle approach.

warning! Once you have linked the Room Combinations Selector control, you cannot make changes to the room and wall layout. If changes are needed, you would have to remove the Selector control link, make your changes, and then re-link the Selector control.

note: Remember that, for testing purposes, you can work with these controls within the software. For example, you can select or deselect a wall's Toggle control to indicate that the wall is open (Toggle is selected) or closed (Toggle is deselected). You can also select an option in the Room Combinations Selector control.

Once you provide the details of a room combine layout and which of its walls are movable, Halogen is then able to calculate the number of possible room combinations. Each standalone room and room combination is seen by the HAL System as a unique room, and each room is given its own Room Processor within which you can configure processing specific to that room.
