A brown half 19-inch receiver for fixed SpeechLine installations

The Sennheiser SL Rack Receiver DW-7-BR is the stationary receiver in the SpeechLine Digital Wireless range. It is built to sit in a 19-inch rack and feed audio from wireless microphone transmitters into a room's sound or conferencing system. Its brown finish, coded #7B481C, suits the timber furniture common in boardrooms and council chambers, where a grey rack unit can look out of place. It works with the mobile transmitters of the system once they are paired.

Specifications that matter for planning

Frequency range: 1910.000 - 1920.000, the band this model covers
Latency: 19 ms

Weight and power: 828 g, 350 mA power consumption, no battery included

Control, connections and setup

An OLED display shows settings directly on the receiver. Bi-directional communication lets you adjust the mobile transmitters from the receiver side, so the operator does not need to reach each microphone. Automatic frequency and interference management helps the link stay stable when other wireless equipment shares the room. Ethernet supports IPv4 and IPv6, and the unit integrates with AMX and Crestron media control protocols, with dedicated Sennheiser iOS apps for settings and status. Audio leaves through one XLR 3M output and two RCA outputs. The system uses 256-bit AES encryption. Both antennas can be mounted at the back or front of the rack, and extension cables for wall mounting are available.

Where it fits in Qatar

In a council chamber in Msheireb or a ministry meeting room in Doha, the rack can sit in a comms cupboard while speakers use wireless microphones at the table, and the brown finish blends with the furniture. At a hotel or convention venue in Lusail, the receiver can feed the ballroom PA from an equipment room. The rated range of -10 °C to +55 °C covers a ventilated, air-conditioned room, but the room temperature should be checked in summer before fitting. In Education City, an AV team can check settings over the network instead of visiting the rack.

What to plan before ordering

Confirm that the 1910.000 - 1920.000 band suits your site and the transmitters you plan to pair with it. Each unit ships with one power supply and two antennas, so check rack space and antenna position first. At 828 g the receiver is light, but a free site survey from SmartRooms Qatar will confirm rack location, cable runs and antenna placement. The product carries a 2-year manufacturer warranty.

Questions about SL Rack Receiver DW-7-BR

What is the Sennheiser SL Rack Receiver DW-7-BR used for?

It is a stationary receiver for the SpeechLine Digital Wireless system. It mounts in a half 19-inch rack and passes audio from wireless microphone transmitters to a room's sound or conferencing equipment. It suits fixed setups such as boardrooms, council chambers and lecture theatres, where the receiver stays in an equipment room while speakers move around with mobile transmitters.

Which frequency range does this model cover?

According to the manufacturer data, this model covers 1910.000 - 1920.000. Before ordering, confirm that this band suits your site and the transmitters you plan to pair with it, because wireless operation depends on the band selected. SmartRooms Qatar can review this during the quotation stage so the configuration matches your requirement.

Is it suitable for a council chamber or ministry meeting room in Doha?

It is designed for fixed rack installation. Its half 19-inch format and 828 g weight make it practical to house in a cabinet near the room's audio equipment. The brown finish, coded #7B481C, suits timber-panelled chambers. Ask for a free site survey to plan cable runs from the rack to each microphone position.

How does the receiver cope with Qatar summer heat?

The rated operating temperature is -10 °C to +55 °C, with relative humidity up to 95 %. Equipment rooms can overheat when air conditioning fails, so place the rack in an air-conditioned, ventilated room, check the room temperature before installation, and keep it out of direct sunlight. The rating covers these conditions but does not replace good ventilation.

Does the unit include a power supply or a battery?

The box contains the receiver, one power supply and two antennas. The manufacturer data lists no battery, and the battery-included field is N. Power consumption is 350 mA. Before connecting, confirm that the power supply input suits Qatar mains of 240 V, 50 Hz with BS 1363 (Type G) sockets, since that detail is not in the product data.

Can the receiver be controlled over a network?

Yes. It has an RJ 45 Ethernet port with IPv4 and IPv6 support, and settings and status can be accessed through AMX and Crestron media control protocols. Dedicated Sennheiser iOS apps are also available. For a university AV team in Education City, this means checking microphone settings from a networked control system rather than visiting the rack. Ask SmartRooms Qatar about integration requirements for your control system.

How are the antennas mounted?

Two antennas come in the box and can be mounted at the back or front of the rack. The best position depends on the cabinet layout and where the microphones are used, so the installer should choose it during the site survey. If the rack is wall-mounted, extension cables for wall mounting are available to position the antennas clear of equipment.

What audio outputs does it provide?

The receiver has one XLR 3M audio output and two RCA audio outputs, plus the RJ 45 network port. XLR suits balanced inputs on a professional mixer or amplifier, while RCA suits unbalanced inputs. In a West Bay boardroom, for example, the XLR output could feed the main room mixer while an RCA output goes to a recording or secondary feed, depending on the room design.

How good is the audio performance?

The data lists 24 bit/48 kHz sampling, a 20 to 20,000 Hz frequency response, dynamic range above 120 dB(A), signal-to-noise ratio above 90 dB(A), typical THD of 0.1 % and 19 ms latency. These figures matter when speech must be amplified clearly and with low delay, such as in a ballroom at a Lusail hotel or a lecture hall at Education City.

What warranty applies, and can we buy it through a government tender?

The manufacturer data gives a 2-year warranty for this model. SmartRooms Qatar supplies government ministries and public bodies through purchase orders (LPOs) and government tenders, including Monaqasat. Payment can be made by bank transfer, cheque or purchase order. Send the model code DW-7-BR and quantity with your LPO reference, and the quotation usually follows within one working day.

Do we need a site survey for a single receiver?

A single 828 g receiver is light, but a free site survey prevents fitting problems. The team checks rack position, cable routes between the receiver and the mixer, and antenna placement against the room layout. This is useful in a government building in Msheireb or an office tower in West Bay, where cable routes and cabinet space need to be coordinated with the building team beforehand.
