What the SL Boundary 114-S DW-7 B does

The Sennheiser SL Boundary 114-S DW-7 B is a wireless table boundary microphone from the SpeechLine Digital Wireless family, made for speech in conference rooms. Without a cable running to the table, it can be repositioned between meetings, which helps in boardrooms where seating plans change. A condenser transducer and half-cardioid pickup pattern direct the capture toward people speaking at the table, and the unit is finished in black.

Key figures for planning and audio quality

These values come from the manufacturer data for this exact model:

Frequency range: EU band 1,880 to 1,900 MHz
Audio frequency response: 40 to 20,000 Hz, sampled at 24 bit/48 kHz
Signal-to-noise ratio: above 90 dB(A)
Dynamic range: below 110 dB(A)
Total harmonic distortion: typically 0.1 %
Microphone sensitivity: 10 mV/Pa
Size and weight: 114 mm high, 85 mm long, 30.8 mm wide, 208 g

A wide frequency response and a high signal-to-noise ratio help keep voices natural and reduce background hiss in quiet rooms. Low distortion keeps speech clear at normal conference levels.

Charging, battery and control

The microphone charges either inductively or over USB. The box includes a BA 40 rechargeable battery rated 2.2 Ah at 3.6 V, and the manufacturer lists a typical operating time of 12 hours on the Accupack. Dedicated battery status LEDs show remaining charge, so a facilities team can confirm readiness before the next session. The CHG 2W wireless power transmitter, which charges two devices, is sold separately.

A programmable microphone button can be set to push-to-talk, push-to-mute, toggle on/off or permanently on, and a two-colour LED ring shows the unit's status. The microphone is compatible with the SL Rack Receiver DW and can be monitored and controlled remotely with the Sennheiser Control Cockpit.

Where it fits in Qatar

Three situations suit this model well:

A ministry or authority boardroom in Msheireb, where a central table needs clear speech pickup without cables crossing the surface.
A university seminar room in Education City linking faculty in Doha with partners abroad, with the receiver mounted in the AV cabinet.
A hotel or serviced apartment meeting room in Lusail, where furniture is rearranged often and cabling needs to stay minimal.

Planning the installation

The operating range is 0 to 45 °C with relative humidity up to 95 %. Summer temperatures in Qatar often exceed 45 °C, so use the microphone in air-conditioned rooms and do not leave it on a table by a window or in a parked vehicle. The in-the-box list does not include a receiver, so confirm which SL Rack Receiver DW setup your system needs before ordering. The data gives only the EU frequency band, so ask the SmartRooms Qatar team to confirm suitability for your installation before ordering.

Questions about SL Boundary 114-S DW-7 B

How does the SL Boundary 114-S DW-7 B differ from the DW-6 B variant?

The manufacturer data for this model lists a dynamic range below 110 dB(A) and a typical battery operating time of 12 hours on the Accupack. The DW-6 B is listed with a dynamic range below 100 dB(A) and a typical 13-hour battery pack operating time. Both share the same EU frequency band, pickup pattern and receiver compatibility. Article number 506965 identifies this exact model, so check it when you request a quote.

Which rooms suit this microphone best?

It suits conference rooms with a central table where people speak from fixed seats. A ministry or authority boardroom in Msheireb is a typical example, where clear speech capture matters and cables across the table are unwanted. The source describes it as dedicated to speech rather than music, so it is aimed at voice in meetings. SmartRooms Qatar can review your room layout before you commit to a quantity.

Which receiver does it work with?

The microphone is compatible with the SL Rack Receiver DW. The receiver is not included in the box, which contains the microphone, a BA 40 rechargeable battery and a quick guide. Confirm the receiver your system needs before ordering, especially if you are adding this microphone to an existing rack. Sennheiser Control Cockpit can monitor and control the unit remotely.

How is the microphone charged?

It can be charged wirelessly using inductive charging or through a USB connection. The BA 40 rechargeable battery is included in the box. The CHG 2W wireless power transmitter charges two mobile devices and is sold separately. For a room with several microphones, plan a charging location close to the table or the equipment cabinet so units are ready for each meeting.

How long does the battery last?

The battery is rated 2.2 Ah at 3.6 V, and the manufacturer lists a typical operating time of 12 hours on the Accupack. Dedicated battery status LEDs show the charge level, so staff can see whether a unit needs recharging before a session. Charge overnight or between meetings to keep the microphone ready during a working day that runs Sunday to Thursday.

What do the programmable button and LED ring do?

The microphone button can be programmed for push-to-talk, push-to-mute, toggle on/off or permanently on, which lets the room's chair or moderator choose how participants open the channel. A two-colour LED ring indicates the unit's status. Agree the button mode with the meeting owner before installation so that the microphone behaves consistently across different meeting formats.

Can it be used in Qatar's summer heat?

The operating temperature range is 0 to 45 °C, with relative humidity up to 95 %. Outdoor and summer temperatures in Qatar often go above 45 °C, so use the microphone only in air-conditioned meeting rooms. Avoid leaving it on a table by a window, in a lobby with direct sun, or in a parked vehicle while carrying out site work.

Is the frequency band approved for use in Qatar?

The manufacturer data lists the EU frequency range as 1,880 to 1,900 MHz, and the data does not state approval for Qatar. Before ordering, ask the SmartRooms Qatar team to confirm that this band and configuration suit your site, especially if the microphone will be used in a government or regulated facility. This check takes place before the quotation is finalised.

How should I place it on a conference table?

The data does not give a pickup distance in metres, so plan placement by testing. The half-cardioid pattern favours sound from the direction the microphone faces, so orient it toward the main speaking positions. The body measures 114 mm high, 85 mm long and 30.8 mm wide, and weighs 208 g. Test with participants speaking from typical seats before fixing the layout.

Can facilities staff monitor it from a Doha office?

Yes, the manufacturer data states that the microphone can be monitored and controlled remotely with the Sennheiser Control Cockpit. A facilities team in a Doha office can check battery state and unit status without visiting each meeting room. Confirm the required software and network setup with the SmartRooms Qatar team when you request a quote, so the monitoring plan is in place from the start.

Is it suitable for a training centre in Al Rayyan where trainers move between rooms?

Yes, the wireless design and rechargeable battery suit trainers who move between rooms, because no cable has to follow the speaker. Keep a charging point in each room or a charged spare battery at hand. The receiver must be set up in each room where the microphone is used, so plan receiver quantities with the SmartRooms Qatar team before ordering.

Can a school in Al Wakrah order several units under one LPO?

Yes, SmartRooms Qatar accepts purchase orders (LPOs) and government tenders, including Monaqasat, and quotations are usually issued within one working day. Ask for one quotation covering every room, including receivers and any separately sold charging units. The product carries the manufacturer's 2-year warranty, which should be noted in the purchase order.
