Overview

A cable-free table microphone kit for conference rooms, the Sennheiser SL Boundary Set DW-6 US pairs one SL Boundary 114-S DW microphone with an SL Rack Receiver DW. It operates in the 1880.000 - 1895.000 frequency range, uses cardioid or half-cardioid pickup, and runs on a rechargeable battery with typical 13-hour operation. Boardrooms and lecture rooms in Doha can request a quote from SmartRooms Qatar.

What the kit includes

The SL Boundary Set DW-6 US is a complete wireless table microphone kit built around one SL Boundary 114-S DW table boundary microphone and one SL Rack Receiver DW, which ships with its power supply. The box also holds a USB cable, one BA 40 rechargeable battery, a GA 4 rack mount kit and a quick guide, so the set can be installed without sourcing extra parts.

Because the microphone connects wirelessly, the receiver can sit in an equipment rack while the microphone stays on the table where people sit. That removes the cable run across or under the table, which is often the main obstacle to rearranging seating or keeping a boardroom tidy.

Pickup pattern, frequency band and audio figures

The condenser capsule offers cardioid and half-cardioid pickup patterns, which help the microphone favour the voices of people seated in front of it. The manufacturer rates the signal-to-noise ratio above 90 dB(A) and the dynamic range below 100 dB(A). Audio is sampled at 24 bit/48 kHz, with a frequency response of 40 to 20,000 Hz and typical total harmonic distortion of 0.1 %.

This variant operates in the 1880.000 - 1895.000 frequency range. Other models in the SpeechLine DW boundary family use different bands, so match the band to your site before ordering and ask SmartRooms Qatar to confirm it in your quotation.

Battery, charging and remote monitoring

The microphone can be charged wirelessly or through USB. The included BA 40 battery is rated at 3.6 V and 2.2 Ah, with a typical operating time of 13 hours. Dedicated battery status LEDs show the charge level, so a presenter can see whether the microphone needs charging before a session starts. The Sennheiser Control Cockpit allows the devices to be monitored and controlled remotely.

Where it fits in Qatar

Three situations suit this kit well:

Boardrooms in West Bay or Msheireb, where ministry or corporate teams meet and the table must stay free of visible cables.
Seminar and tutorial rooms in Education City, where a lecturer moves between the board and the table and needs a microphone that is not tied to a cable.
Meeting rooms in Lusail or Al Sadd that host hybrid sessions with colleagues joining from abroad, where speech needs to be picked up cleanly from seated participants.

Planning the installation

Start by confirming the frequency band and the table layout. Check where the rack receiver will sit, whether the cabinet has room for the rack mount kit, and how the cable path reaches the power supply. The data for this model does not list an operating temperature, so confirm the room environment with the SmartRooms Qatar team before settling the receiver location, particularly in rooms with large windows or heavy afternoon sun.

SmartRooms Qatar offers a free site survey to check the room, table position and receiver location before installation, and can arrange professional installation. Request a quote to confirm the configuration, the frequency band and the accessories your project needs. Quotations usually follow within one working day.

Questions about SL Boundary Set DW-6 US

What is the SL Boundary Set DW-6 US used for?

It is a wireless table microphone kit for picking up speech in meeting rooms and boardrooms without visible cables. The set pairs an SL Boundary 114-S DW table microphone with an SL Rack Receiver DW, so people can speak at a normal volume from the table. It suits a boardroom in West Bay or Msheireb, where the table must stay clear during long meetings.

Who should choose this kit over a wired table microphone?

Teams that rearrange meeting rooms often, or that want the table kept free of cables. The microphone is fully wireless, weighs 208 g, and charges through USB or wirelessly, so it moves with the meeting instead of staying tied to one socket. If the room needs a fixed cable run, compare wired options before deciding.

What comes in the box?

The set includes one SL Boundary 114-S DW table boundary microphone, one SL Rack Receiver DW with its power supply, a USB cable, one BA 40 rechargeable battery, a GA 4 rack mount kit and a quick guide. The manufacturer also lists a CHG 2W wireless power transmitter as available separately, so it is not part of this set. Mention it in your quotation request if you need it.

What frequency range does this model use?

This variant, the DW-6 US, operates in the 1880.000 - 1895.000 frequency range. Other SL Boundary Set DW variants use different ranges, for example 1893.000 - 1906.000 for the DW-5 US, so the band must match your project before you buy. Ask SmartRooms Qatar to confirm the band in your quotation and check it against the room plan.

Can the microphone be charged without a cable?

Yes. The SL Boundary 114-S DW can be charged wirelessly or through USB, and the set includes a USB cable. The separate CHG 2W wireless power transmitter is not in the box. In an executive boardroom, a presenter can top up the microphone between meetings without searching for a cable, and the status LEDs show the charge level.

How long does the battery last, and how will staff know when it needs charging?

The set includes one BA 40 rechargeable battery rated at 3.6 V and 2.2 Ah, with a typical operating time of 13 hours. Dedicated battery status LEDs show the charge level, so a presenter can see before a session starts whether the microphone needs charging. For a full-day training course in a Msheireb meeting room, plan a charging routine between sessions.

Which room in Education City suits this kit?

A seminar or tutorial room in Education City, where a lecturer moves between the board and the table, is a good match for a cable-free boundary microphone. The cardioid and half-cardioid patterns favour the speaker in front of the microphone, and the frequency response runs from 40 to 20,000 Hz. For a large lecture theatre with several microphones, the quotation should be based on a site survey.

How is the rack receiver installed?

The SL Rack Receiver DW is designed for an equipment rack, and the set includes a GA 4 rack mount kit. Choose a rack position close to the room's meeting equipment and check the cable path to the power supply. The data for this model does not list an operating temperature, so confirm the room environment with the SmartRooms Qatar team before fixing the final receiver location.

Do I need a site survey before installing it?

A site survey is advisable in rooms with large tables or other wireless devices nearby. SmartRooms Qatar offers a free site survey to review the room layout, table position and receiver location before installation, and professional installation is available. Settling the frequency band and placement on paper first avoids rework once the cabinet and cables are in place.

How does the DW-6 US differ from the DW-5 US?

Both variants share the same box contents, the same condenser microphone specifications, 24 bit/48 kHz sampling and a two-year warranty in the source data. The main difference is the frequency range: the DW-6 US uses 1880.000 - 1895.000, while the DW-5 US uses 1893.000 - 1906.000. Compare the band against your site before choosing between them.

Does the set come with a warranty?

Yes. The manufacturer lists a two-year warranty for this set, and products supplied by SmartRooms Qatar are covered by the manufacturer's warranty. Ask for the warranty terms in writing within your quotation if your procurement process requires it. For government tenders, including Monaqasat, SmartRooms Qatar usually issues quotations within one working day and accepts purchase orders and bank transfer.
