Overview

The Sennheiser SL Boundary 114-S DW-5 B is a black wireless table microphone from the SpeechLine Digital Wireless family, made for speech in conference rooms. Its half-cardioid pickup, programmable microphone button and two-colour LED status ring suit cable-free meetings. The battery typically runs 12 hours on the accupack and charges wirelessly or over USB. Suited to boardrooms and training rooms across Doha and Lusail.

A cable-free table microphone built for speech

The Sennheiser SL Boundary 114-S DW-5 B is a wireless table boundary microphone from the SpeechLine Digital Wireless range. It is made for speech rather than music, and it sits on a conference table so people can speak from their seats without cables running across the surface. This variant carries article number 506646 and is listed in black.

Within its family, the manufacturer data for this article lists a dynamic range below 110 dB(A) and a typical accupack runtime of 12 hours, which helps buyers compare it with other variants in the series.

Pickup, battery and what the indicators tell you

The condenser capsule uses a half-cardioid pickup pattern, which favours voices in front of the unit. The data lists a signal-to-noise ratio above 90 dB(A), an audio frequency response of 40 to 20,000 Hz and a sampling rate of 24 bit/48 kHz. Total harmonic distortion is typically 0.1 %, and microphone sensitivity is 10 mV/Pa.

Power comes from a BA 40 rechargeable battery (2.2 Ah, 3.6 V) supplied in the box. Battery status LEDs show the remaining charge, while the two-colour LED ring indicates the microphone's status. The programmable button can be set to push-to-talk (PTT), PTM, toggle on/off or permanent on, so the way your room runs decides how it behaves.

Charging and integration with the SpeechLine DW system

The microphone can be charged inductively or over USB, so it does not depend on a single charging method. The manufacturer lists a separate CHG 2W wireless power transmitter as an optional accessory. The unit works with the SL Rack Receiver DW, and the manufacturer notes that it can be monitored and controlled remotely through the Sennheiser Control Cockpit.

Where it fits in Qatar

Boardroom in West Bay or Lusail: executives join calls with teams abroad and need a clear table without cables.
Training room in Education City: a presenter moves around the table while the microphone stays in place.
Government meeting room in Msheireb: a team that wants fewer cables on the table and a tidy setup for each session.

What to plan before you order

The rated operating temperature is 0 to 45 °C with relative humidity up to 95 %. Qatar summers regularly pass 45 °C, so install the microphone in air-conditioned rooms, away from sunlit windows, and never leave it in a parked vehicle. The manufacturer data does not list an outdoor rating, so treat this as an indoor device. The listed frequency range is EU 1,880 to 1,900 MHz, so confirm with the SmartRooms Qatar team that this band suits your site before ordering.

A free site survey helps you check receiver placement and coverage across the room. For a school or ministry ordering several units, one LPO or government tender can cover the full set, and quotations are usually provided within one working day. Products are covered by the manufacturer's warranty, which the data lists as 2 years.

If the SL Boundary 114-S DW-5 B fits your meeting rooms, request a quote from SmartRooms Qatar and include your room layout, the number of seats and your receiver and charging plans.

Questions about SL Boundary 114-S DW-5 B

What is the Sennheiser SL Boundary 114-S DW-5 B designed for?

It is designed for speech in conference rooms. The wireless table microphone lets people speak from their seats without cables, using a half-cardioid condenser pickup. It suits boardrooms, meeting rooms and training rooms in Doha where presenters and participants need clear voice pickup from the table surface. At 208 g, it is light enough to reposition when a room layout changes.

How should I place it on a table to get the best pickup?

Because the pickup pattern is half-cardioid, it favours sound arriving from the front of the unit. Position it so that the people who speak most sit in front of it, rather than behind it or against a wall. In a long West Bay boardroom, test positions with the people who will use the table before fixing the layout. A free site survey from SmartRooms Qatar can help you plan this.

Which receiver does it work with?

The SL Boundary 114-S DW-5 B is compatible with the SL Rack Receiver DW, which belongs to the SpeechLine Digital Wireless family. The data lists a wireless connection and an EU frequency range of 1,880 to 1,900 MHz. Before ordering, confirm the receiver and frequency band with the SmartRooms Qatar team, especially if you plan to run several microphones in one room or across a building.

How is the microphone charged?

It can be charged wirelessly through inductive charging, or over USB. The BA 40 rechargeable battery, rated 2.2 Ah and 3.6 V, is included in the box. The manufacturer lists a separate CHG 2W wireless power transmitter as an optional accessory. Battery status LEDs show the charge level, so staff can check the unit before a meeting and avoid a flat microphone during an important session.

How long does the battery last between charges?

The manufacturer gives a typical operating time of 12 hours on the accupack. Actual runtime depends on how the microphone is used, so plan to charge after long sessions or overnight. The battery status LEDs make it easy to see the remaining charge. If you are comparing variants in the series, check the article number, since the listed runtime differs across some models.

What can the programmable microphone button do?

The button can be set to PTT, PTM, toggle on/off or permanent on. Push-to-talk keeps the microphone muted until a speaker presses the button. Toggle on/off switches the microphone with each press, and permanent on keeps it live. The two-colour LED ring shows the status. Choose the mode during setup to match how your room runs, for example a government session where speakers should speak deliberately.

Can it be monitored or controlled remotely?

Yes. The manufacturer states that it can be monitored and controlled remotely with the Sennheiser Control Cockpit. This suits IT and AV teams running several rooms, such as a university building in Education City or a ministry office, who want to check microphone status from one central point. Ask the SmartRooms Qatar team to confirm what your setup needs before ordering.

Can it be used in Qatar's summer heat or outdoors?

The rated operating temperature is 0 to 45 °C, with relative humidity up to 95 %. Qatar summer temperatures can exceed 45 °C, so use the microphone in air-conditioned rooms, away from direct sunlight and hot windows. The data does not list an outdoor rating, so it is not suited to terraces or open-air areas such as a stadium concourse. Keep it on the table indoors at a comfortable room temperature.

Does the listed frequency band suit a Qatar installation?

The manufacturer data lists the frequency range as EU 1,880 to 1,900 MHz. Because this figure is given for the EU, do not assume it fits your site without checking. Confirm with the SmartRooms Qatar team whether the band and configuration suit your intended use before ordering. A site survey before installation is a good moment to check this, especially for a multi-room deployment in a new building in Lusail.

How is this variant different from the other DW variants in the series?

This model is the DW-5 B, article number 506646. Many listed specifications match the other variants in the series, but the manufacturer data for this article lists a dynamic range below 110 dB(A) and a typical 12-hour accupack runtime. Compare the article number and listed specifications against the other variants before ordering, so the unit matches your room and any existing receiver.

What should a facilities team in Lusail check before installing the receiver?

Check the receiver's distance from the table, the cable routes and the rack position before installation is scheduled. The SL Rack Receiver DW must be able to serve the microphone's location, so note where the table sits relative to the rack. A free site survey from SmartRooms Qatar can document these points and help you agree a layout your team can maintain.

How do I order for a government tender covering several rooms?

Ask for one quotation covering all units, listing article number 506646, the quantity per room and any optional CHG 2W charger. SmartRooms Qatar supports LPOs, government tenders including Monaqasat, and payment by bank transfer, cheque or purchase order. Quotations are usually provided within one working day. Include your room list and tender specification so the quotation matches the requirement exactly.
