A brown wireless microphone set built for speech

The Sennheiser SL TS 133 GN Set DW-7 BR is a cable-free tablestand microphone kit for people who speak at a lectern, podium or boardroom table. The brown finish identifies this version, and it comes with the same core kit: a tablestand, a gooseneck microphone, a rack receiver and a rechargeable battery. Everything needed for setup is in the box, so one order covers a single speaking position from start to finish.

Frequency band, audio and what to check first

This version is listed with a frequency range of 1910.000 - 1920.000 in the manufacturer data. Wireless bands depend on the site, so ask the SmartRooms Qatar team to confirm that the band suits your room and any other wireless equipment before you place the order. The audio figures are strong for speech:

Frequency response: 75 to 20,000 Hz
Sampling: 24 bit/48 kHz
Dynamic range: above 120 dB(A)
Signal-to-noise ratio: above 90 dB(A)
Pickup pattern: cardioid, with typical THD of 0.1 %

A cardioid pattern is designed to pick up sound from the front, so the speaker's voice is favoured over reflections and noise arriving from behind the microphone.

Charging, battery life and remote control

The tablestand uses a BA 40 rechargeable battery rated at 2.2 Ah and 3.6 V, with a typical operating time of 10 hours. Dedicated battery status LEDs show the charge state, so staff know when a battery needs attention. The tablestand can be charged wirelessly using the Qi standard or through USB. The CHG 2W wireless charging base for two mobile devices is a separate accessory and is not part of this set. The set can also be monitored and controlled remotely with the Sennheiser Control Cockpit.

Where it fits in Qatar

Three scenarios show where this set performs best:

Lecture theatre in Education City: the lecturer keeps the microphone at a fixed spot on the lectern without cables crossing the stage, and the 40 cm gooseneck is set for a single speaker.
Ministry boardroom in Msheireb: the gooseneck sits in front of the chair during a panel discussion, while the rack receiver is housed in the AV cabinet.
Hotel conference room in West Bay: a speaker at a conference podium uses the set, with the battery charged in advance of the event.

Qatar summers bring temperatures above 45°C and dust storms. The rated operating range for this set is 0 to 40 °C, so keep the tablestand and receiver in air-conditioned rooms and never leave the set in a hot vehicle or an outdoor tent.

Planning the installation

Mount the SL Rack Receiver DW in a rack using the included GA 4 rackmount kit, away from direct heat sources.
Confirm the mains requirements of the supplied power supply before installation, because the manufacturer data does not state them.
Decide where the gooseneck will sit relative to the speaker, since its 40 cm length sets the reach.
Include battery charging in your room preparation so the BA 40 is full before each session.

The manufacturer provides a 2-year warranty on this set. If the room layout is still being decided, ask for a free site survey. Request a quote from SmartRooms Qatar, which supplies this set with delivery to all eight municipalities of Qatar. Quotations are usually issued within one working day, and we accept purchase orders (LPOs).

Questions about SL TS 133 GN Set DW-7 BR

What is the Sennheiser SL TS 133 GN Set DW-7 BR used for?

It is a wireless tablestand microphone kit for speech at a podium, lectern or boardroom table. It combines a tablestand, an MEG 14-40 B gooseneck microphone with cardioid pickup, an SL Rack Receiver DW and a BA 40 rechargeable battery. It suits lecturers, chairs and speakers in schools, universities and government meeting rooms across Doha who need a fixed microphone position without cables crossing the room.

Which frequency range does this version use?

The manufacturer data lists this DW-7 BR version with a frequency range of 1910.000 - 1920.000. Wireless bands depend on the site, so the SmartRooms Qatar team should confirm that this range suits your room and any other wireless equipment before you order. Mention your site when you request the quote so the band can be checked first.

How long does the battery last?

The BA 40 rechargeable battery is rated at 2.2 Ah and 3.6 V, with a typical operating time of 10 hours. Dedicated status LEDs show the charge level, so staff can see when it needs recharging. The manufacturer lists power consumption of 350 mA, so plan a full charge before each long session or event.

Can the tablestand be charged without a cable?

Yes. The tablestand supports the Qi wireless charging standard and can also be charged through USB. The CHG 2W wireless charging base is designed for two mobile devices, is available separately and is not included in this set. Add it to your quote request only if you need it for mobile devices.

Does the set work with other gooseneck microphones?

The set is compatible with all Sennheiser XLR-3 gooseneck microphones, so the supplied MEG 14-40 B can be swapped for a compatible model if a speaker needs a different reach. The supplied gooseneck is 40 cm long. Confirm the exact microphone you plan to use with the SmartRooms Qatar team before ordering.

Can the set be monitored or controlled remotely?

Yes, with the Sennheiser Control Cockpit, which can monitor and control the set. This is useful for technical teams that look after several rooms at once. The manufacturer data does not list the software's system requirements, so ask SmartRooms Qatar what your IT team will need before installation.

What connections does the receiver provide for the room?

The manufacturer data lists an XLR 3M audio output on the set. The SL Rack Receiver DW ships with its power supply and a GA 4 rackmount kit. The mains specification of the supplied power supply is not stated in the data, so confirm it with the SmartRooms Qatar team before you plan the rack location near your audio connection point.

Can it be used outdoors or in a hot space in Doha?

The rated operating temperature range is 0 to 40 °C. Qatar summers can exceed 45°C, so the tablestand and receiver belong in air-conditioned rooms, not outdoor marquees, open-air events or parked vehicles. Keep the battery out of direct sunlight as well, especially during outdoor setup and transport between sites.

Is this suitable for a ministry boardroom in Msheireb?

Yes, for a boardroom where one or two members speak from a fixed table position. The 40 cm gooseneck reaches the speaker, and the receiver can sit in the AV cabinet. Before ordering, a free site survey helps confirm the table layout, the receiver location and whether the wireless band suits the room.

Would it work in a lecture theatre at Education City?

Yes, for a lecture theatre where the lecturer stays near the lectern. The cardioid pickup favours the speaker's voice, and the 75 to 20,000 Hz frequency response covers normal speech. Plan one set per lectern, test the microphone position before final installation, and charge the battery before each long lecture.

Is it a good fit for a hotel conference room in West Bay?

It suits a podium speaker at conferences, awards evenings and panel sessions in air-conditioned hotel halls. The typical operating time is 10 hours, so charge the battery before the event. The 40 cm gooseneck and cardioid pattern keep the sound focused on the speaker and reduce pickup from behind the microphone.

Can a school or government office buy this with a purchase order?

Yes. SmartRooms Qatar accepts purchase orders (LPOs) and government tenders, including those on Monaqasat, and payment can be made by bank transfer, cheque or purchase order. For example, a school in Al Rayyan equipping several rooms can send one LPO covering all the sets. The product is covered by the manufacturer's 2-year warranty.
