HAL Applications Conference Switchboard The Conference Switchboard block supports dynamic routing of Far End Audio sources. This block is useful when more than one room must share a single VoIP or Video Conference resource. It's also useful when a room needs to access one or more remote rooms on a campus in order to include them in a conference. In some cases a combination of these scenarios is required. The function of the Conference Switchboard could be accomplished using a standard matrix mixer, but that would require a user to avoid disallowed routing (like 1:1 or 2:2 etc.), and ensure that To and From Far End pairs are correctly wired. This Conference Switchboard simplifies the process. Multi-Channel Processing Blocks In order to get the best performance from an AEC application, the same signal processing parameters used to feed a room loudspeaker must be applied to the AEC reference signal as well. To simplify this process, special blocks that mirror the processing for room and reference channels include: ƒƒ Tracking Compressor ƒƒ Tracking ANC ƒƒ Multi-Channel PEQ ƒƒ Multi-Channel Shelf Conference Room Combine Block Conferencing in a room combine environment is a complex task without a specialized Room Combine Processor designed to handle room mix, far-end mix and AEC reference routing. Halogen's unique ability to do conferencing within a room combine scenario without complex wiring and routing makes it easy. Halogen provides a highly integrated Conference Room Combine block that greatly simplifies conferencing in a room combine configuration. The block combines room sources, selects a proper reference, and sends audio to appropriate locations as rooms combine. It also provides support for maintaining a proper AEC Reference with local Voice Lift. This block supports unique mixes from Record and Room outputs. An independent AEC Reference Output is provided for each room to accommodate various microphone locations and unique room processing outside the Conference Room Combine block. Also inherently provided in this block are support for background music selection and paging per room. Data Sheet - 30

Conference Switchboard
°e Conference Switchboard block supports dynamic routing of Far End
Audio sources. °is block is useful when more than one room must share a
single VoIP or Video Conference resource. It’s also useful when a room needs
to access one or more remote rooms on a campus in order to include them
in a conference. In some cases a combination of these scenarios is required.
°e function of the Conference Switchboard could be accomplished
using a standard matrix mixer, but that would require a user to avoid disal-
lowed routing (like 1:1 or 2:2 etc.), and ensure that To and From Far End
pairs are correctly wired. °is Conference Switchboard simplifies the process.
Multi-Channel Processing Blocks
In order to get the best performance from an AEC application, the same
signal processing parameters used to feed a room loudspeaker must be
applied to the AEC reference signal as well. To simplify this process, special
blocks that mirror the processing for room and reference channels include:
²
Tracking Compressor
²
Tracking ANC
²
Multi-Channel PEQ

Multi-Channel Shelf
Conference Room Combine Block
Conferencing in a room combine environment is a complex task without a
specialized Room Combine Processor designed to handle room mix, far-end
mix and AEC reference routing. Halogen's unique ability to do conferencing
within a room combine scenario without complex wiring and routing makes
it easy.
Halogen provides a highly integrated Conference Room Combine block
that greatly simplifies conferencing in a room combine configuration. °e
block combines room sources, selects a proper reference, and sends audio
to appropriate locations as rooms combine. It also provides support for
maintaining a proper AEC Reference with local Voice Lift.
°is block supports unique mixes from Record and Room outputs. An
independent AEC Reference Output is provided for each room to accom-
modate various microphone locations and unique room processing outside
the Conference Room Combine block.
Also inherently provided in this block are support for background music
selection and paging per room.
