The OmniStream Pro architecture includes a mix of AT-OMNI-111-WP wallplate networked AV encoders, (single-channel) and AT-OMNI-112 (dual-channel) networked AV decoders.
The SASS team installed two wallplates in each of the six West Wing divisible spaces – one in the front of the room and one in the back – and one in the Greenville Room, with a second in storage if needed. Front and back wallplates were added to the four remaining rooms on the other side of the hotel.
OmniStream decoders were added in a variety of places to better suit delivery to end points, which include Epson Cinema 660 projectors and Screen Innovations 160-inch screens. Some were installed in ceilings by Epson projectors, and others within an existing 42U equipment rack that was rewired and reused for this project. The IT-friendly rack also integrates two 48-port Cisco network switches and all pertinent audio equipment, including a Bose ControlSpace EX-1280C DSP, and a Sennheiser EW 500 G4 Series wireless antenna system.
As a Bose enthusiast, the ControlSpace EX-1280C DSP was especially critical to execute Gardner’s vision.
The DSP moves the audio to Bose FreeSpace DS 100F loudspeaker systems, which were deployed in a 70-volt configuration to accommodate the longer runs.
“The FreeSpace system replaced these enormous wedge-shaped speakers that were just cancelling each other out based on how they were spaced and positioned,” said Gardner. “ The audio integrity is now perfect for these spaces.”
The Sennheiser system improves presentation audio with a wireless system in a redundant A/B system configuration that includes high-quality handheld microphones, and a mix of single- and dual-channel receivers. A distribution amplifier in the rack brings in the various antennas from the system’s power amplifier.
Gardner notes that Atlona, Bose and Sennheiser all worked closely with him and his team to customize the
him and his team to customize the system and provide the flexible programming environments he needed. He also had strong praise for Screen Innovations, noting that the company made life easier by eliminating any need for flush-mounting screens.
“We really had to think through the programming, because we couldn’t simply cut-and-paste the same setting for every space since each was unique,” said Gardner. “This was especially true when it came to the HDMI video feeds, the microphone system and the DSP flows. These companies made a very challenging programming and integration project a lot more seamless than it could have been.”
