Maris Interiors, London: Teams Room Boardroom With LED Wall

Q: How do you connect a Teams Room to a rack 12 metres away?

Over the network and Cat cable. At Maris Interiors a Yealink EN300 encoder and DE300 decoder carry video between the boardroom and the rack, an Icron Raven 3301 extends USB 3 over Cat cable (rated to 100 metres) and a Yealink RCH80 switch connects the Teams Rooms devices, so nothing in the room needs to sit next to the equipment.

Q: Can a meeting room turn itself on and off?

Yes. Maris Interiors added an Extron TLP Pro 300M touch panel and a network occupancy sensor: the room powers up when someone walks in and switches off after 60 minutes with nobody there, and the panel handles power, volume and source selection. See how we design meeting room AV.

Quick reference: Microsoft Teams Room for the London head office boardroom of fit-out contractor Maris Interiors: a Yealink MVC S50 system with A50 video bar, the client's existing Ledman LED wall refitted into a new wall recess, Yealink AVoIP and Icron USB extension to a rack 12 metres away, a Q-SYS amplifier and architectural subwoofer for music, and an Extron touch panel with an occupancy sensor that powers the room on and off.

A boardroom for a fit-out contractor's own head office

Maris Interiors is a London design and build fit-out contractor, founded in 1977. When it redesigned the boardroom at its own head office, it wanted the room to show clients the standard it builds for them: a simple Microsoft Teams Room that sounds good when music plays in presentations, with nothing on the newly panelled ceiling. Strive AV designed and installed the room around equipment Maris already owned, a Ledman LED wall that had been sitting on a mobile trolley, and stayed on for three follow-on jobs: speakers for the reception, BYOD switching and a touch panel control system with an occupancy sensor.

The challenge: reuse the LED wall, keep the ceiling clear

The boardroom was being renovated around the AV, on a turnaround of a few weeks. The LED wall had to come down for the works and go back up in a new recess in the wall, and the acoustic panelling meant no ceiling speakers or microphones. Maris plays music in client presentations, so audio needed real bass, not just speech from a video bar. The equipment rack sat 12 metres away down a corridor, so video, USB and control all had to travel that far reliably. And staff wanted to present from their own laptops rather than a fixed room PC.

Key Requirements

•A simple Microsoft Teams Room staff and clients can use without help
•Reuse of the client's existing Ledman LED wall in a new wall recess
•No speakers or microphones on the new acoustic ceiling
•Bass for music played during client presentations
•Video and USB carried 12 metres to the equipment rack
•Installation on a renovation timescale of a few weeks

A Yealink Teams Room built around the LED wall

Strive AV installed a Yealink MVC S50 Microsoft Teams Rooms system: the A50 video bar with its camera, microphones and speakers above the LED wall, an MCore mini PC, an MTouch Plus touch console and a room sensor. Maris's Ledman LED wall was taken down for the renovation and refitted into the new recess on six B-Tech BT8390 brackets, reusing its original trolley arms. To bridge the 12 metres to the rack, a Yealink EN300 encoder and DE300 decoder carry video over the network, an Icron Raven 3301 extends USB 3 over Cat cable, and a Yealink RCH80 switch and CT200 controller tie the system together. For music, a Q-SYS SPA2-200 amplifier drives a compact 10 inch architectural subwoofer alongside the video bar's own speakers. After handover Maris came back for more. Two design column speakers and an amplifier went into the reception, an HDMI 2.0 matrix switcher added BYOD inputs, and an Extron TLP Pro 300M touch panel with a network occupancy sensor now handles power, volume and source selection: the room turns on when someone walks in and powers down after 60 minutes with nobody there.

Questions about this boardroom

Can you reuse an existing LED wall in a Microsoft Teams Room?

Yes. At Maris Interiors the client's own Ledman LED wall, previously on a mobile trolley, was refitted into a new wall recess and became the main display for a Yealink MVC S50 Teams Room, with the A50 video bar mounted above it. Reusing it put the budget into the conferencing, audio and control. More on Microsoft Teams Rooms in London.

How do you connect a Teams Room to a rack 12 metres away?

Over the network and Cat cable. At Maris Interiors a Yealink EN300 encoder and DE300 decoder carry video between the boardroom and the rack, an Icron Raven 3301 extends USB 3 over Cat cable (rated to 100 metres) and a Yealink RCH80 switch connects the Teams Rooms devices, so nothing in the room needs to sit next to the equipment.

How do you get bass for music in a boardroom without ceiling speakers?

Add a small subwoofer to the video bar. At Maris Interiors a Q-SYS SPA2-200 amplifier drives a compact 10 inch architectural subwoofer alongside the Yealink A50 video bar, so music in client presentations has proper low end while the new acoustic ceiling stays clear of speakers and microphones.

Can a meeting room turn itself on and off?

Yes. Maris Interiors added an Extron TLP Pro 300M touch panel and a network occupancy sensor: the room powers up when someone walks in and switches off after 60 minutes with nobody there, and the panel handles power, volume and source selection. See how we design meeting room AV.
