Overview

The Sennheiser SL Boundary Set DW-3 UK is a wireless table microphone kit for conference rooms. It pairs a condenser boundary microphone with a rack-mounted receiver, so no cables cross the table. The microphone charges by induction or USB, and its battery status LEDs show remaining battery life. It suits boardrooms and meeting rooms in Doha, West Bay and Lusail where a clean table matters.

What arrives in the DW-3 UK set

The DW-3 UK kit centres on the SL Boundary 114-S DW, a wireless table boundary microphone, and the SL Rack Receiver DW, which ships with its own power supply. The box also contains a BA 40 rechargeable battery, a USB cable, a GA 4 rack mount kit and a quick guide. No separate parts are needed to get the system running, so you order one complete set.

Audio and battery figures to check against your room

The microphone uses a condenser transducer with cardioid and half-cardioid pickup patterns, which lets the system favour the people seated close to it. The manufacturer lists a frequency response of 40 to 20,000 Hz, a signal-to-noise ratio above 90 dB(A), a dynamic range below 100 dB(A) and sampling at 24 bit/48 kHz. The battery pack is rated at a typical 13 hours of operating time.

Frequency range: 1880.000 - 1900.000 as listed by the manufacturer
Battery: 2.2 Ah at 3.6 V, one pack included
Microphone sensitivity: 10 mV/Pa
Product weight: 208 g
Manufacturer warranty: 2 years

Where the DW-3 UK fits in Qatar

In a boardroom in West Bay, a ministry team can place the microphone at the centre of a conference table and keep the rack receiver in the AV cabinet away from the table. Cables stay off the surface, which matters when delegates bring laptops and paperwork. In Education City, a university seminar room running hybrid sessions can use the same layout, with the microphone passed between presenters rather than re-cabled for each speaker.

In Lusail or The Pearl, a developer's sales suite or a serviced-office meeting room benefits from the inductive charging option. The microphone can rest on a suitable charging point between meetings, while the USB route lets staff top up the battery at a desk. The manufacturer also offers a separate wireless power transmitter, the CHG 2W, if you want a dedicated charging point.

Planning the installation

Decide where the microphone will sit during meetings and where the rack receiver will be mounted before you order. The GA 4 rack mount kit is supplied, so the receiver can go into a rack, but check that the cabinet has room and airflow around it. A free site survey from SmartRooms Qatar lets the team check table surfaces, distances and cabinet space before installation.

The manufacturer data does not list an operating temperature range for this set. If the receiver or microphone will sit near a window in a room that is not fully air-conditioned, ask the SmartRooms Qatar team to confirm the environment first. Because this is the UK-coded variant, also confirm the power supply plug and regional suitability for your site before ordering.

Questions about SL Boundary Set DW-3 UK

Who is the Sennheiser SL Boundary Set DW-3 UK for?

It suits rooms where a cable-free table is a priority, such as a boardroom in West Bay where a ministry team meets colleagues in Doha and abroad. The set pairs one wireless table boundary microphone with a rack receiver, so it fits a room with one main conference table. It is a good choice when a clean table and simple seating layout matter more than microphone count.

What is included in the box?

The set includes one SL Boundary 114-S DW table boundary microphone, one SL Rack Receiver DW with its power supply, one BA 40 rechargeable battery, one USB cable, one GA 4 rack mount kit and a quick guide. The rack mount kit covers receiver mounting, so check the cabinet space before ordering. Confirm the full kit contents with the SmartRooms Qatar team when you request your quotation.

What pickup patterns does the microphone offer?

The data lists cardioid and half-cardioid pickup patterns. A cardioid pattern favours sound from the front and reduces sound from behind, which suits a speaker sitting directly in front of the microphone. Half-cardioid covers a wider area in front, which helps when several people sit along one side of the table. Confirm with the team whether you can switch between patterns on the unit before planning seating.

How long does the battery last during meetings?

The manufacturer lists a typical battery operating time of 13 hours for the battery pack, which is rated at 2.2 Ah and 3.6 V. That rating suits a full working day of meetings in many rooms, but actual runtime depends on how the microphone is used. Charge the battery at the end of each day so it is ready for the first meeting the next morning.

How is the microphone charged in a shared office in Lusail?

The microphone charges by induction or through the included USB cable, so staff can top it up at a desk if no wireless charging point is available. Battery status LEDs show remaining battery life, so the team knows when to recharge before an important session. The CHG 2W wireless power transmitter is available separately if you want a dedicated charging point.

How does the DW-3 UK differ from the DW-3 EU or DW-3 AU?

The published specifications for the DW-3 UK, DW-3 EU and DW-3 AU are listed as identical, including the 1880.000 - 1900.000 frequency range and the 2-year warranty. This model is identified by the UK suffix and article number 506617. The choice therefore comes down to the regional variant, so confirm power supply and regional suitability with SmartRooms Qatar before you order.

Can an IT team in Doha monitor the set remotely?

Yes. The manufacturer states that the set can be monitored and controlled remotely with the Sennheiser Control Cockpit. This helps support teams that manage meeting rooms across several sites, because they can check device status without visiting each room. Ask the SmartRooms Qatar team which software or hardware the Control Cockpit requires in your setup before you order.

Which video conferencing platforms does it work with?

The source data does not list supported conferencing platforms, the connection method to a computer, or compatible room systems. Before ordering for a hybrid meeting between Doha and teams abroad, ask SmartRooms Qatar to confirm compatibility with your platform and room equipment. The set includes a USB cable, but the data does not describe its use with a specific device, so confirm that too.

How much space does the rack receiver need in a university AV cabinet?

The receiver mounts using the supplied GA 4 rack mount kit. In a lecture hall in Education City, measure the free rack space and check airflow around the receiver and its power supply before installation. A free site survey from SmartRooms Qatar can confirm the layout inside the cabinet before any cabling work begins, which avoids rework on a busy campus schedule.

Can the microphone be used in a hot room that is not air-conditioned?

The data does not list an operating temperature range, so suitability for hot spaces cannot be confirmed from the source. Summer temperatures in Qatar can exceed 45 degrees Celsius, so for a meeting room in Al Sadd with west-facing windows or a partly cooled area, ask SmartRooms Qatar to confirm the environment before installation. Keep the receiver in a controlled space until the team has confirmed suitability.

Is there a warranty, and can a school in Al Rayyan order several sets on an LPO?

The manufacturer lists a 2-year warranty for this set. A school in Al Rayyan equipping several classrooms or meeting rooms can submit a purchase order (LPO) covering multiple sets. SmartRooms Qatar delivers to all eight municipalities of Qatar and usually returns quotations within one working day. Ask for a quotation that lists each set separately so the LPO matches the quote.
