Brand: Biamp
SKU: biamp-devio-dtm-1
Availability: InStock

Overview

The Biamp Devio DTM-1 is a tabletop microphone that uses beamtracking to follow conversations across three 120-degree zones, covering the full 360 degrees of a meeting table. It ships with a mounting plate, connects with a single cable to a Devio SCR-20 or SCR-25 unit, and can be daisy-chained to a second DTM-1. It suits boardrooms and conference rooms in Qatar where remote participants need to hear every speaker clearly.

What the Devio DTM-1 does at the table

The Devio DTM-1 is a tabletop microphone built for video conferencing rooms. Its beamtracking function divides the table into three 120-degree zones, follows whoever is speaking and blends those voices together, so participants at the far end hear a natural conversation rather than a distant, uneven pickup. Because the three zones together cover 360 degrees, the microphone suits round tables and boardroom layouts where people sit on every side.

Specifications that matter when you plan the room

Audio: 8-element digital array with an active beamformed pattern, frequency response of 150 Hz to 16 kHz at plus or minus 3 dB, and a dynamic range of 92 dB, A-weighted.
Directivity: two selectable modes, Middle of Table (360 degrees) for a central position or End of Table (120 degrees) for a single direction.
Noise suppression: four settings (Off, Low, Medium and High), with Low as the default.
Mute control: three capacitive touch mute buttons and three LED mute status indicators with a green and red LED.
Power and size: under 1 W, phantom powered from a Devio SCR-20 or SCR-25; 56 mm high, 130 mm wide, 121 mm deep and 0.27 kg.

Installation and cabling

Installation uses a single cable from the microphone to the Devio SCR-20 or SCR-25 unit, and the included mounting plate secures the DTM-1 to the table. A second DTM-1 can be daisy-chained through its additional RJ-45 port, with a maximum of two microphones per chain and up to 15 metres (49 feet) between devices. Measure cable runs from the SCR unit before ordering, especially in larger rooms where the second microphone sits far from the first. SmartRooms Qatar offers a free site survey to confirm table layout and cable routes before installation.

Where it fits in Qatar

A boardroom in West Bay or Lusail where executives join calls with teams in Europe or Asia and every speaker must be heard clearly.
A seminar room in Education City running hybrid lectures, with a lecturer and students gathered around one central table.
An administration room at a hospital in Al Sadd that connects regularly with a head office abroad.

Environment and planning notes

The rated ambient operating range is 0 to 40 degrees C (32 to 104 degrees F), with humidity from 0 to 95 percent non-condensing and altitude up to 2,000 m. In Qatar this makes the DTM-1 a good fit for air-conditioned meeting rooms, not unconditioned lobbies or outdoor areas where summer temperatures can exceed 45 degrees C. If you are unsure about a room's conditions, confirm them with the SmartRooms Qatar team before ordering. The DTM-1 carries FCC Part 15B, CE, UL and C-UL listings, RoHS compliance and a 2-year warranty.

SmartRooms Qatar supplies the DTM-1 with delivery to all eight municipalities of Qatar and professional installation, and accepts purchase orders and government tenders.

Questions about Devio DTM-1

What is the Biamp Devio DTM-1 used for?

The Devio DTM-1 is a tabletop microphone for video conferencing rooms. Its beamtracking follows whoever is speaking across three 120-degree zones and blends those voices so remote participants hear a natural conversation. It suits boardrooms, seminar rooms and meeting rooms where people sit on several sides of the table and remote callers need clear audio.

We are fitting out a boardroom in West Bay with a round table. Is one DTM-1 enough?

For a small or medium round table, a single DTM-1 in Middle of Table mode covers the full 360 degrees. For a long or wide table, add a second unit through the extra RJ-45 port, which allows a maximum of two microphones per daisy chain. A free site survey from SmartRooms Qatar can confirm the layout before you order.

Which Devio unit powers the DTM-1, and how far can it sit from it?

The DTM-1 is phantom powered from a Devio SCR-20 or SCR-25, draws under 1 W and connects through a single cable. The maximum distance from the SCR unit to the microphone is 49 feet (15 metres), and the same limit applies between daisy-chained DTM-1 units. Measure your cable route before ordering so the microphone stays within that run.

Our university seminar room in Education City has a long table with the lecturer at one end. Which directivity mode should we use?

Set the DTM-1 to End of Table mode for that layout. It narrows pickup to a 120-degree zone, which keeps the lecturer's voice focused and reduces pickup from the far side of the room. Middle of Table mode uses the full 360-degree pickup and suits a microphone placed in the centre of a table where people sit around it.

Will the DTM-1 cope with air conditioning noise in a meeting room in Doha?

The DTM-1 includes automatic noise suppression with four settings: Off, Low (the default), Medium and High. Start with the default, run a test call with the air conditioning operating normally, and move up a level only if remote participants still hear background noise. Higher settings can change how voices sound, so test before you commit.

Can we place the DTM-1 in an outdoor pavilion or an unconditioned lobby in Lusail?

That is not a suitable location. The rated ambient operating range is 0 to 40 degrees C (32 to 104 degrees F), with humidity from 0 to 95 percent non-condensing and altitude up to 2,000 m. Summer temperatures in Qatar often exceed 45 degrees C, so the DTM-1 belongs in air-conditioned meeting rooms. If a space is borderline, confirm its conditions with the SmartRooms Qatar team before requesting a quote.

How is the DTM-1 mounted on a conference table?

The microphone ships with a mounting plate that secures it to the table, and installation uses a single cable running to the Devio SCR unit. Plan the cable route under the table and leave a little slack near the microphone. SmartRooms Qatar offers professional installation, and a free site survey can check placement so the unit sits clear of laptops, papers and air vents.

Does the DTM-1 let participants mute themselves?

Yes. The DTM-1 has three capacitive touch mute buttons and three LED mute status indicators with a green and red LED. Anyone seated at the table can mute or unmute from the nearest button, which suits meetings where one person needs to step out of the discussion during a call without disrupting others.

Can the DTM-1 be used with third-party conferencing systems?

The DTM-1 uses a custom, proprietary digital interface and two RJ-45 connectors: one to a Devio SCR-20 or SCR-25 and one to an additional DTM-1. Compatibility with other codecs or room controllers is not covered by the available data, so ask SmartRooms Qatar to confirm your existing system before ordering rather than assuming it will connect.

Is the DTM-1 suitable for US federal bids or other tendering rules?

The DTM-1 complies with the US Trade Agreement Act (TAA), which allows it to be included in GSA Schedule contractors' bids for the US federal government. It also carries FCC Part 15B, CE, UL and C-UL listings and RoHS compliance. Qatari ministries and authorities can order through a purchase order or a Monaqasat tender, and quotations are usually issued within one working day.

What warranty covers the DTM-1, and how do I request a quote?

The Devio DTM-1 has a 2-year warranty. Keep your purchase order and installation records with the unit. To request a quote, send SmartRooms Qatar the quantity, your room layout and whether you need one unit or a daisy-chained pair. Quotations are usually issued within one working day.
