Overview
The Sennheiser SL TS 133-S DW-7 B is a discontinued wireless table stand for XLR-3 gooseneck microphones. Its microphone button shows active or muted status in two colours, it charges by Qi or USB, and its BA 40 battery runs up to 10 hours. Organisations that already own it, or are comparing models, should request a quote for a compatible replacement.
What the SL TS 133-S DW-7 B is
The Sennheiser SL TS 133-S DW-7 B is a wireless table stand from the SpeechLine Digital Wireless range. It holds a Sennheiser XLR-3 gooseneck microphone on a table without a cable running back to the audio system, which suits speakers who need to move freely rather than stay tied to a floor box. The stand is designed for speech: podium discussions, speeches and lectures. The manufacturer lists the colour as black.
The stand is compatible with all Sennheiser XLR-3 gooseneck microphones. Microphones are not included in the box, so the gooseneck should be chosen as part of the same order. The box contains the table stand, one BA 40 rechargeable battery, a quick guide and a safety guide.
Specifications that matter for a purchase decision
- Frequency range: EU 1,880 to 1,900 MHz, as listed by the manufacturer
- Audio: 75 to 20,000 Hz frequency response, 24 bit/48 kHz sampling and a dynamic range above 120 dB(A)
- Signal-to-noise ratio: above 90 dB(A), with typical total harmonic distortion of 0.1 %
- RF sensitivity: below -90 dBm
- Battery: BA 40 rechargeable battery, 2.2 Ah and 3.6 V, typically 10 hours of operation
- Operating temperature: 0 °C to 40 °C (14 °F to 131 °F)
- Weight: 650 g
- Warranty: 2 years from the manufacturer
Where it fits in Qatar
Three situations show where the stand earns its place:
- A university lecture theatre in Education City, where a visiting lecturer presents from a table at the front and needs a microphone that stays out of the way of slides and notes.
- A government boardroom in West Bay, where several officials sit at one table and each speaking position needs its own stand and gooseneck, with the status display showing who is live.
- A hotel conference room in Lusail, hosting a seminar where delegates move between the lectern and the table during question time.
What to plan for before ordering
The listed operating temperature runs from 0 °C to 40 °C, which is lower at the top than summer conditions outdoors in Doha, where temperatures can exceed 45 °C. Keep the stand in an air-conditioned room, away from direct sun through windows and from warm equipment, and do not leave it in a car, a store room or a marquee. Plan a charging routine around the typical 10-hour rating of the BA 40 battery.
The frequency range is listed as EU 1,880 to 1,900 MHz. Include this band in your enquiry so the team can check it against your site and any other wireless equipment you run. This model's data does not list dimensions, so confirm the footprint against your table before ordering.
Because Sennheiser has discontinued this model, the most useful next step is a quote request that names your room, your microphone requirements and the number of speaking positions. SmartRooms Qatar will use that information to recommend a current equivalent or a compatible replacement. Request a quote today and we will usually come back to you within one working day.

Questions about SL TS 133-S DW-7 B
Is the Sennheiser SL TS 133-S DW-7 B still available as a new unit?
Sennheiser has discontinued the SL TS 133-S DW-7 B, so it is no longer part of the manufacturer's current range. For a new room or a like-for-like replacement, request a quote for a current equivalent or compatible model. Share your microphone type and room layout so the quote matches your existing setup.
What is this table stand designed to do?
It holds a Sennheiser XLR-3 gooseneck microphone on a table for speech, including podium discussions, speeches and lectures. Because it is wireless, no cable runs from the table to the audio system, so the speaker can move without cables crossing the floor. The status display on the microphone button shows whether the microphone is active or muted, which helps a presenter confirm they are live.
Which microphones can I fit to it?
The manufacturer states compatibility with all Sennheiser XLR-3 gooseneck microphones. The microphone is not included in the box, which contains the table stand, one BA 40 rechargeable battery, a quick guide and a safety guide. Choose the gooseneck length and type to suit your table and speaker positions, and include it in your quote request so the setup is planned as one package.
How long does the battery last, and how is the stand charged?
The stand includes one BA 40 rechargeable battery rated at 2.2 Ah and 3.6 V, with typical operation of 10 hours. It can be charged wirelessly using the Qi standard or through USB. Dedicated battery status LEDs show remaining charge, so a technician can check it before a session. Plan a charging routine that suits long conferences in Doha.
Can the stand be monitored or controlled remotely?
According to the manufacturer, it can be monitored and controlled with the Sennheiser Control Cockpit. This suits an AV team in a university or government building that runs several rooms and wants to check microphone status from one point. Ask the team to confirm what the Control Cockpit requires on your network and devices before you commit to an order.
Will the stand cope with Qatar's summer heat?
The listed operating temperature is 0 °C to 40 °C (14 °F to 131 °F). Summer temperatures outdoors in Qatar can exceed 45 °C, so keep the stand in an air-conditioned room, away from direct sunlight through windows and from warm equipment. Do not leave it in a car, store room or outdoor marquee, and check the room conditions before installation.
Which frequency band does it use?
The manufacturer lists the EU frequency range as 1,880 to 1,900 MHz. Before ordering, confirm that this band suits your site and any other wireless systems nearby. Include the room location and a list of wireless equipment in your quote request so the SmartRooms Qatar team can review the band against your real environment.
How heavy is it, and how big is it?
The manufacturer lists a product weight of 650 g, which is light enough to move between tables by one person. The data for this model does not include height, length or width, so this page does not state them. Before ordering, measure the table area and the space around the microphone position, and send those measurements with your enquiry.
How would it suit a lecture theatre at Education City?
A lecturer presenting from a table at the front of a lecture theatre can speak without cables crossing the stage or front rows. The gooseneck microphone keeps a consistent position in front of the speaker, and the status display shows when the microphone is live. Send the team the number of speaking positions and your room layout so the quote matches how lectures are delivered.
Is it suitable for a government boardroom in West Bay?
In a boardroom where several officials sit at one table, each speaking position needs its own stand and gooseneck microphone. The cable-free design makes it easier to rearrange seating between meetings without moving floor connections. Tell the team how many seats need microphones and whether the table is used for presentations, so the quote covers the right number of units.
How can schools and government organisations buy this in Qatar?
SmartRooms Qatar supplies organisations across Qatar and delivers to all 8 municipalities. Quotations are usually issued within one working day, and we accept purchase orders (LPOs), government tenders including Monaqasat, and payment by bank transfer, cheque or purchase order. The manufacturer's warranty is 2 years. Because this model is discontinued, state your purpose and quantities so the team can propose a current equivalent.
