What this table stand does on a conference table

The Sennheiser SL TS 133-S DW-4 B is a battery-powered base that holds a Sennheiser XLR-3 gooseneck microphone in front of a speaker. It sits on a table, so the microphone can be placed at the right height and angle without running a cable from the table to the mixer or amplifier. The stand is built for speech, such as podium discussions, speeches and lectures, where clear voice pickup matters more than music reproduction.

Specifications that matter for this variant

This is the DW-4 variant, article number 506626. Its published data includes the following:

Operating range: 10 °C to 45 °C (50 °F to 113 °F), with relative humidity up to 95 %.
Audio: 75 to 20,000 Hz frequency response, 24 bit/48 kHz sampling, signal-to-noise ratio above 90 dB(A) and dynamic range above 120 dB(A).
Latency and distortion: 19 ms latency and typically 0.1 % total harmonic distortion.
Radio: EU frequency range 1,880 to 1,900 MHz and RF sensitivity below -90 dBm.
Battery: one BA 40 rechargeable accupack (2.2 Ah, 3.6 V), typically 10 hours of operation, included in the box.
Input impedance: 30 kΩ.
Size and weight: 166.7 mm high, 120 mm long, 47.9 mm wide and 650 g.

Charging, battery status and remote control

The stand supports the Qi wireless charging standard and can also be charged by USB. Dedicated battery status LEDs show remaining charge, and the microphone button's two-colour display tells the speaker whether the microphone is active or muted. A separate CHG 2W wireless charging base for two mobile devices is available, but it is not included with the stand. The stand can be monitored and controlled with Sennheiser Control Cockpit.

Where it fits in Qatar

A ministry or authority meeting room in Msheireb or Lusail is a typical case. Attendees speak from a long table, and one stand per seat keeps cables off the surface and makes the room easy to rearrange. Battery power means the microphone position does not depend on where the nearest table socket sits.

In a West Bay hotel function room, panel discussions and keynote speeches can be set up quickly between events. The rechargeable pack lets the organiser place the stand where the session needs it, without taping cables across a stage. Confirm that the room stays within the 10 to 45 °C rating during events.

In a university lecture theatre in Education City, a lecturer speaking from a table or lectern can keep the microphone in a fixed spot and move between slides without carrying a wired mic. With 19 ms latency and a 75 to 20,000 Hz response, the setup suits both lectures and seminars.

What to plan before ordering

The box contains the table stand, one BA 40 rechargeable battery, a quick guide and a safety guide. It does not include a gooseneck microphone, so choose the XLR-3 model you need before ordering; our team can confirm compatibility before quoting. Measure the table depth against the 120 mm by 47.9 mm footprint, and keep the stand out of direct sun and away from windows, because summer temperatures in Doha can exceed 45 °C. We offer a free site survey to check table positions and rooms before delivery, and schools or government bodies ordering several units can pay by purchase order (LPO). The manufacturer's two-year warranty covers the product. Request a quote from SmartRooms Qatar, and we usually respond within one working day.

Questions about SL TS 133-S DW-4 B

What is the Sennheiser SL TS 133-S DW-4 B used for?

It is a battery-powered wireless table stand that holds a Sennheiser XLR-3 gooseneck microphone steady on a table. It suits speakers at podium discussions, speeches and lectures, where the speaker needs a clear voice without a cable running across the table. It fits meeting rooms, lecture spaces and conference halls where one or two people speak from a fixed position.

Which microphones fit the SL TS 133-S DW-4 B?

The stand is compatible with Sennheiser XLR-3 gooseneck microphones. The box contains the table stand, one BA 40 rechargeable battery, a quick guide and a safety guide, but no gooseneck microphone, so the microphone is specified separately. Tell the SmartRooms Qatar team which gooseneck model you plan to use so we can confirm compatibility before quoting.

How does the DW-4 B differ from the other SL TS 133-S DW variants?

The DW-4 B, article number 506626, is listed at an operating range of 10 °C to 45 °C and a 19 ms latency figure. The DW-6 and DW-7 variants are listed at 0 °C to 40 °C and do not show a latency figure, so this model suits warmer rooms better. The DW-3 and DW-5 share the 10 °C to 45 °C rating. Confirm the article number in your quotation before ordering.

How long does the battery last on a single charge?

The included BA 40 accupack is a 2.2 Ah, 3.6 V rechargeable pack, and the manufacturer gives a typical operating time of 10 hours. Actual runtime depends on how the microphone is used, so a long conference day may need a recharge break. The battery status LEDs show the remaining charge, so the chair can plan a recharge between sessions.

Can the stand be charged wirelessly as well as by USB?

Yes. The stand supports the Qi wireless charging standard and can also be charged by USB. A separate CHG 2W wireless charging base for two mobile devices is available, but it is not included with the stand. If you also want to charge phones at the same table, add that base to your quotation.

Will the stand cope with Qatar's summer heat?

The rated operating temperature is 10 °C to 45 °C, with relative humidity up to 95 %. Summer temperatures in Doha can exceed 45 °C, so keep the stand out of direct sunlight, away from windows and parked vehicles, and use it in air-conditioned rooms. If a venue cannot hold that range, confirm the setup with the SmartRooms Qatar team before requesting a quote.

Is it suitable for a lecture theatre at Education City?

Yes, for a lecturer who speaks from a table or lectern at the front of a teaching room. The stand holds the gooseneck microphone in a fixed position, so the lecturer can move between slides without carrying a wired mic. With 19 ms latency and a 75 to 20,000 Hz audio response, it suits lectures and seminars. We can arrange a free site survey to check table positions first.

Can a ministry meeting room in Msheireb use it?

Yes, for a meeting room where attendees speak from a long table. Each speaking position can have its own stand, which keeps cable runs off the conference table. Government bodies in Qatar often order through purchase orders (LPO) or Monaqasat tenders, and SmartRooms Qatar supports both, so one quotation can cover every seat that needs a stand.

Would it suit a conference room in a West Bay hotel?

Yes, for panel discussions and keynote speeches where speakers sit at a table in a function room. Hotel function rooms are often reconfigured between events, and a battery stand avoids routing cables across a stage. Check that the room stays within 10 to 45 °C during events, and confirm the gooseneck microphone you intend to use before requesting a quote.

Can a school in Al Rayyan or Al Wakrah order several units at once?

Yes. A school fitting out several assembly halls or classrooms can request one quotation covering every position. SmartRooms Qatar accepts purchase orders (LPO), bank transfer and cheque, and delivers to all eight municipalities of Qatar. Ask for a free site survey to confirm each table position before the order is placed.

Can a training centre at Ras Laffan or Mesaieed use it?

It suits industrial training rooms where a presenter speaks from a table, provided the room is air-conditioned and stays within 10 to 45 °C. The stand is battery-powered, so no cable needs to reach the table, which helps when furniture is moved between sessions. The manufacturer's two-year warranty applies, and delivery to Ras Laffan or Mesaieed can be included in your quotation.
