A tablestand microphone kit for fixed speaking positions

The SL TS 133 GN Set DW-3 AU is a wireless tablestand kit built around a 40 cm MEG 14-40 B gooseneck microphone. The box includes the SL Tablestand 133-S DW, the SL Rack Receiver DW with its power supply, a GA 4 rackmount kit, a BA 40 rechargeable battery, a quick guide and a safety guide. Because the receiver is separate from the table unit, it can sit in an equipment cabinet while the speaker works without a cable.

Pickup and battery performance that matter for speech

The microphone uses a condenser transducer with a cardioid pickup pattern, which concentrates pickup on the speaker in front of it and reduces noise from behind. The listed signal-to-noise ratio is above 90 dB(A), the dynamic range is above 120 dB(A), and audio is sampled at 24 bit/48 kHz. The audio frequency response runs from 75 to 20,000 Hz, with total harmonic distortion typically 0.1 %.

The BA 40 battery is a 2.2 Ah, 3.6 V pack, and Sennheiser lists a typical operating time of 10 hours with it. The tablestand can be charged wirelessly using the Qi standard or through USB, and dedicated battery status LEDs show how much runtime remains. Plan a charging routine so the battery starts each session fully charged.

Where it fits in Qatar

In a lecture theatre at Education City, a lecturer can walk beside the lectern while presenting, with no microphone cable crossing the stage. The SL Rack Receiver DW can be mounted in the room's equipment cabinet, with its XLR audio output feeding the existing sound system. In a ministry boardroom in Doha, the tablestand can sit on a presentation podium so officials speak without cables crossing the table. Hotel conference rooms in West Bay or Lusail can use the set for opening speeches and panel moderation, where the speaker stays at one spot for the session.

Heat is a practical planning point. The listed operating temperature is 0 °C to 40 °C (14 °F to 131 °F), while summer temperatures in Qatar can exceed 45 °C. Keep the tablestand and rack receiver in air-conditioned rooms, away from sunlit lobbies, glazed booths and unventilated cabinets.

What to plan before ordering

Confirm the listed frequency range of 1880.000 - 1900.000 suits your site before the order is placed.
Choose a rack position for the SL Rack Receiver DW and GA 4 rackmount kit, with a clear cable route to the lectern.
Allow for the listed product weight of 3302.6 g when choosing a podium or lectern surface.
Plan a charging routine so the BA 40 battery starts each session fully charged.
Use the Sennheiser Control Cockpit if you need to monitor or control the set remotely.

Questions about SL TS 133 GN Set DW-3 AU

What is the SL TS 133 GN Set DW-3 AU used for?

It is a wireless tablestand microphone kit for speakers who stay at a fixed point, such as a lectern, podium or panel table. The kit pairs a 40 cm MEG 14-40 B gooseneck microphone with an SL Rack Receiver DW, so the speaker's voice reaches the room's audio system without a cable running to the table. It suits lecture theatres, boardrooms and conference rooms in Qatar where cable runs are difficult to route.

How does the DW-3 AU variant differ from the other SL TS 133 GN Set models?

This variant carries article number 506621 and lists a frequency range of 1880.000 - 1900.000, with a product weight of 3302.6 g. Other variants list different frequency ranges, such as the DW-4, DW-5, DW-6 and DW-7 sets, and the other DW-3 sets list a different product weight. Compare the article number and frequency range with your quotation before ordering so you receive the exact variant you need.

What comes in the box?

The set includes the SL Tablestand 133-S DW, the MEG 14-40 B gooseneck microphone, a BA 40 rechargeable battery, the SL Rack Receiver DW with its power supply, a GA 4 rackmount kit, a quick guide and a safety guide. The receiver power supply is listed as included, so one set covers both the table unit and the rack receiver. Checking the contents against this list helps when the delivery is received on site.

What is the frequency range, and should I check it before ordering in Qatar?

The source data lists the frequency range for this variant as 1880.000 - 1900.000, without a unit. Wireless microphones operate within defined frequency bands, so confirm that this range suits your site and the applicable rules before you order. Ask the SmartRooms Qatar team to confirm the band against your planned use when you request a quote, and quote article number 506621 so the correct variant is reviewed.

How long does the battery last, and how is the set charged?

The BA 40 rechargeable battery is included, rated at 2.2 Ah and 3.6 V. Sennheiser lists a typical operating time of 10 hours with that battery. The tablestand charges through the Qi wireless standard or by USB, and dedicated battery status LEDs show remaining battery life. For long conference days, charge the unit overnight so each session starts with a full battery.

Can the set handle the heat of a Qatari summer or an unconditioned room?

The listed operating temperature is 0 °C to 40 °C (14 °F to 131 °F), while summer temperatures in Qatar can exceed 45 °C. Install the tablestand and rack receiver in air-conditioned rooms only. Avoid sunlit lobbies, glazed booths and unventilated cabinets. If the conditions in your room are unclear, confirm them with the SmartRooms Qatar team before installation.

How good is the audio, and what pickup pattern does it use?

The microphone is a condenser type with a cardioid pickup pattern, so it concentrates on sound from in front of the speaker. The listed signal-to-noise ratio is above 90 dB(A), the dynamic range is above 120 dB(A), and the audio frequency response runs from 75 to 20,000 Hz. Audio is sampled at 24 bit/48 kHz with total harmonic distortion typically 0.1 %, which suits spoken content in lecture halls and boardrooms.

Can the tablestand be monitored or controlled remotely?

Yes. The source data states that the set can be monitored and controlled with the Sennheiser Control Cockpit. For an IT or AV team managing several rooms, this means checking the status of the set without walking to the lectern. Before installation, agree the connection method and network requirements for your site with your AV contractor.

How would this kit be used at a university in Education City?

A lecturer in an Education City lecture theatre can move beside the lectern while presenting, with the MEG 14-40 B gooseneck microphone kept close to the speaker's mouth. The SL Rack Receiver DW sits in the room's equipment cabinet, and its XLR audio output feeds the existing sound system. Test the microphone position with a real presenter during planning to find the best distance and reduce background noise.

Is the set suitable for a ministry boardroom or a hotel event room in West Bay or Lusail?

In a ministry boardroom in Doha, the tablestand lets presenters speak without cables crossing the table. In a hotel conference room in West Bay or Lusail, the set suits opening speeches and panel moderation. The typical battery time is 10 hours and the listed warranty is 2 years. Book a free site survey first to confirm the room layout and the receiver location.

Can SmartRooms Qatar supply this kit against an LPO or a government tender?

Yes. SmartRooms Qatar supplies this kit against purchase orders (LPOs) and government tenders, including those on Monaqasat, and accepts payment by bank transfer, cheque or purchase order.
