Hands on: I tested the Biamp MRB-M-X400-T - read what this meeting room solution is actually like

Biamp recently made a splash in the video bar market with its stunningly good Parlé VBC 2500, but its main focus has always been the professional audio-visual (AV) space. It has a solution for every room size, with the MRB-M-X400-T kit on review providing all the audio components for a medium-sized meeting room with up to 11 participants.

The Biamp kit comprises a TesiraFORTÉ X 400 digital signal processor (DSP) unit, a Tesira AMP-450BP speaker amplifier, a Parlé TTM-X beam tracking table microphone with expansion box, two Desono C-IC6 ceiling speakers and plenty of plenum-rated Cat5e cabling to connect it all together. Biamp has its own range of VC cameras and supplied us with the Vidi 250, which has a 120° field of view (FoV) and digital pan, tilt and zoom (PTZ) functions.

A full room installation will need to be done by professional fitters, but we had a basic configuration created in the lab in an hour. A handy feature is that power only needs to be supplied to the DSP unit as its four gigabit ports deliver 30W PoE+ services over Cat5e cables to all other components. The low–profile speakers will fit in most drop ceiling spaces and their 130° coverage is designed to accommodate low ceilings. The AMP-450BP amplifier unit can be concealed in the ceiling using the speaker’s “backpack” brackets, and it has four RJ-45 ports so you can add two more speakers.

There’s no need to worry about sound configuration, as Biamp’s Launch process does it all for you. Press the Launch button on the DSP unit and the system measures the meeting room’s acoustics by emitting a series of eerie sounds that reminded us of the 1956 Forbidden Planet sci-fi movie.

The DSP analyses the audio feedback, configures all the components to your environment and presents a Launch report card in its local web interface. The bottom line is that you may need help fitting the kit but you won’t need an audio expert to fine-tune it.

For the full audio/visual meeting experience the simplest solution is to connect the DSP’s USB port to a room PC with a Full HD monitor where the mic and speakers appear as speakerphone devices. Add the Vidi 250 camera to the host as a separate USB device and it will use its integral auto-framing functions.

The camera reacts quickly with delays of no more than three seconds as it tracked speakers moving around our meeting room. Video quality is great, with the camera presenting a sharply focused image and efficient backlight compensation.

The microphone’s beam tracking technology uses four 90° zones to track voices and allow speakers to roam freely but still be heard clearly. In practice, this works extremely well, and the speakers also receive our accolades for their exceptional sound quality, natural-sounding voices and warm bass.

Another scenario is to connect the kit to a UC compute device, and for this Biamp provided Lenovo’s ThinkSmart Core+Control product. Just plug in the DSP and camera to its USB ports, add an external monitor, connect the Control tablet and you’re ready to go.

It runs Windows 10 IoT and we used its setup wizard to select Teams operations (Skype for Business is also supported). After logging into our Microsoft 365 account it appeared as a Teams Rooms on Windows device and we could use the tablet to swiftly schedule and join meetings.

The Biamp MRB-M-X400-T is a great choice for businesses that want to transform their meeting room into a professional conferencing space. All the components are surprisingly easy to deploy, Biamp’s Launch feature provides slick automated room configuration and the Vidi camera delivers great video quality.
