MRB-L-VT4-T

What the MRB-L-VT4-T bundle includes

The MRB-L-VT4-T is a discontinued audio bundle for large meeting rooms, built around the TesiraFORTE AVB VT4 processor. It is sized for meetings of up to 18 people and supplies processing, microphones, loudspeakers, network connection and cabling in one kit, so a room can be outfitted from a single quotation rather than sourced item by item.

• Processing: one TesiraFORTE AVB VT4 processor and one TesiraCONNECT TC-5 connection device
• Microphones: one Parlé TTM-X table microphone and one Parlé TTM-XEX expansion table microphone
• Loudspeakers: four Desono C-IC6 ceiling speakers
• Amplification and UC: one Tesira AMP-450BP PoE+ powered amplifier and one Tesira EX-UBT UC interface
• Cabling: three 25 ft (7.5 m) plenum Cat 5e cables, three 10 ft (3 m) plenum Cat 5e cables and one 3 ft (0.9 m) Cat 5e cable

Microphone pickup and audio in a room of 18 people

The Parlé microphones use Beamtracking, which follows participants who move around the table or stand to present, so people do not need to lean toward a fixed device. The Desono C-IC6 ceiling speakers are tuned for voice reproduction in conference rooms, and the system tunes itself automatically to suit rooms with different acoustic profiles. A custom acoustic echo cancellation stage supports remote participants. When several people speak at once, speech remains clear, and the microphone mute buttons and LEDs stay in sync with the UC software.

Network setup and UC platform compatibility

TesiraCONNECT and the single cable connection scheme let installers run audio over the network with reduced configuration work, and the PoE+ powered Tesira AMP-450BP takes its power from the network connection. The bundle is certified for Microsoft Teams Rooms and listed as Cisco Verified, which matters for IT managers who standardise conferencing on one platform. Confirm your platform version and existing network switches with the SmartRooms Qatar team before ordering.

Where this bundle fits in Qatar

Three situations suit a kit at this scale.

• A boardroom in Msheireb or West Bay: a ministry or company meeting room where executives join calls with teams abroad and 18 participants is the expected maximum.
• A seminar room in Education City: a university or training centre room where the lecturer moves around while the Beamtracking microphones keep speech clear for remote students.
• A training room in the Industrial Area or Mesaieed: an energy or industrial company training space where operators join regional sessions, and one kit reduces the number of suppliers involved in fitting out the room.

Planning installation and what to check first

Ceiling speaker positions, cable routes and microphone placement all depend on the room, so a free site survey before ordering is the practical first step. Check the ceiling type and the depth of the void above it, and plan routes for the 25 ft, 10 ft and 3 ft cables. SmartRooms Qatar provides professional installation and delivery to all eight municipalities of Qatar, and accepts purchase orders (LPOs) and government tenders. The manufacturer data does not state an operating temperature range, so the installation environment, especially any non-air-conditioned space, should be confirmed with the SmartRooms Qatar team before speakers are placed.

Discontinued model: replacement and support

Biamp has discontinued the MRB-L-VT4-T and lists MRB-L-X400-T as its replacement. If your room already runs this bundle, request a quote for a current equivalent and send details of the processor, microphones and UC platform in use, so the replacement matches the existing setup. The manufacturer data lists a 5-year warranty for this bundle.

To compare this bundle with a current equivalent or to plan a room for up to 18 participants, request a quote from SmartRooms Qatar. The team usually replies with a quotation within one working day.
