What this receiver does in a SpeechLine wireless system

The Sennheiser SL Rack Receiver DW-5-US is the stationary receiving unit of the SpeechLine Digital Wireless range. It mounts in a standard equipment rack, receives signal from mobile transmitters and passes the audio on through its outputs. Because it is a fixed receiver, it stays in a comms cabinet or AV room while presenters move freely around the space.

Frequency band and audio figures that matter

This model operates in the 1893 to 1906 MHz band, which is the detail that distinguishes it from other models in the range. Its audio path is specified at 24 bit/48 kHz with a frequency response of 20 Hz to 20 kHz, a signal-to-noise ratio above 90 dB(A) and a dynamic range above 120 dB(A). Latency is 19 ms and typical total harmonic distortion is 0.1 %. RF sensitivity is better than -90 dBm. Before ordering, confirm with the SmartRooms Qatar team that the 1893 to 1906 MHz band suits your site and the transmitters you already own, because the frequency band must match across the system.

Control, connectivity and pairing

Bi-directional communication lets you adjust transmitter settings from the receiver
A quick pairing process links each transmitter securely to the receiver
Ethernet with IPv4 and IPv6, plus AMX and Crestron media control integration
256-bit AES encryption for secure operation
Audio outputs of XLR 3M and 2 x RCA, with an RJ 45 network port

An OLED display shows status during setup. Antennas can be mounted at the back or front of the rack, and the series also offers extension cables for wall mounting.

Where it fits in Qatar

A university lecture theatre in Education City can house the receiver in its AV rack, feeding the amplifier and recording system from the XLR and RCA outputs while lecturers use wireless microphones. A government ministry boardroom in Msheireb can connect the RJ 45 port to the room control system so that settings are managed centrally. A hotel ballroom in West Bay hosting daily conferences can keep the receiver in a back-of-house cabinet, where the rated -10 to +55 °C operating range gives margin, although airflow in a hot cabinet still needs attention.

Planning the installation

Reserve rack space for a half-width 19-inch unit and map cable routes for the XLR and RCA outputs and the RJ 45 connection. The receiver weighs 828 g, so a suitable rack shelf or rack ears are sufficient. A free site survey helps confirm antenna placement at the front or back of the rack and whether extension cables are needed for wall mounting. The box includes the power supply and two antennas; no battery is included.

Questions about SL Rack Receiver DW-5-US

What is the Sennheiser SL Rack Receiver DW-5-US used for?

It is the stationary receiver in the SpeechLine Digital Wireless system. It mounts in a standard 19-inch rack, picks up audio from mobile transmitters and sends it to a sound system, recorder or control room. It suits conference rooms, lecture theatres and meeting spaces in Qatar where wireless microphones feed fixed AV equipment.

Which frequency band does this model use?

The DW-5-US operates in the 1893 to 1906 MHz range. Other models in the SL Rack Receiver DW family use different bands, so check the band before matching transmitters. Ask the SmartRooms Qatar team to confirm that 1893 to 1906 MHz suits your site and any transmitters you already own before you order.

What audio performance does the receiver specify?

The receiver specifies 24 bit/48 kHz sampling, an audio frequency response of 20 Hz to 20 kHz, a signal-to-noise ratio above 90 dB(A) and a dynamic range above 120 dB(A). Latency is 19 ms and typical total harmonic distortion is 0.1 %. These figures suit speech in boardrooms, lecture halls and conference rooms where clarity matters most.

Can I change transmitter settings from the receiver?

Yes. Bi-directional communication lets you adjust the settings of paired mobile transmitters from the receiver side, so a technician does not need to walk into the room. Automatic frequency and interference management works alongside this, and the OLED display shows status during setup.

How does it connect to a control system?

The receiver has an RJ 45 Ethernet port with IPv4 and IPv6 support. Settings and status can be reached through AMX and Crestron media control protocols, and the manufacturer also provides Sennheiser iOS apps and a third-party API. Confirm which control protocol your room controller uses before ordering.

Is the wireless link secure?

The receiver uses 256-bit AES encryption, and the pairing process securely links each transmitter to the receiver. For ministries and corporate boardrooms in Doha reviewing their wireless and network policies, this is a detail to share with the IT team early in the project.

Which outputs and cables do I need?

The audio outputs are one XLR 3M and two RCA connections, and the network connection is RJ 45. Plan cables for each output your amplifier, mixer or recorder uses, and allow a route for the antenna cables. A site survey helps confirm cable runs before the rack is fitted.

Will it cope with the heat in a Doha equipment room?

The rated operating temperature is -10 °C to +55 °C, with relative humidity up to 95 %. Summer temperatures in Doha often exceed 45 °C, so the rack should sit in a ventilated, air-conditioned comms room rather than an unventilated cabinet. Confirm airflow with the SmartRooms Qatar team during planning.

Can the receiver be wall mounted in a meeting room?

It is designed for a 19-inch rack, and the SL Rack Receiver DW series includes extension cables for wall mounting. The antennas can be mounted at the front or back. For a meeting room in West Bay or Lusail, a site survey helps decide whether a rack or a wall-mounted cable run suits the room layout better.

What is in the box?

The package includes the SL receiver rack unit, a power supply and two antennas. A battery is not included, so the receiver runs from its supplied power supply. Check that the contents match your order before installation, and ask the SmartRooms Qatar team if your layout needs additional accessories.

What warranty applies to this model?

According to its source data, this model carries a 2-year manufacturer warranty. SmartRooms Qatar supplies the product with that manufacturer's warranty. If your project is a school or government contract, state the warranty period in your tender documents and ask us to confirm the terms in the quotation.

How do schools and government buyers order this receiver?

Send your requirement to SmartRooms Qatar and we will return a quotation, usually within one working day. We support purchase orders (LPOs), government tenders including Monaqasat, and payment by bank transfer, cheque or purchase order. For a multi-room project, list all the receivers and transmitters you need in one request.
