SL Boundary Set DW-7 BR

What the SL Boundary Set DW-7 BR includes

This is the brown edition of Sennheiser's SpeechLine digital wireless boundary range for conference rooms. At its centre is the SL Boundary 114-S DW, a table boundary microphone with a condenser transducer, which works with the SL Rack Receiver DW. The box also holds a power supply for the receiver, a USB cable, a BA 40 rechargeable battery, a GA 4 rack mount kit and a quick guide, so the set can be installed without sourcing parts separately.

The specifications that shape the sound

When comparing table microphones, start with pickup and noise performance. The microphone uses cardioid and half cardioid pickup patterns and lists a signal-to-noise ratio above 90 dB(A). Audio frequency response runs from 40 to 20,000 Hz with 24 bit/48 kHz sampling. Other figures to review on the datasheet:

• Frequency range: 1910.000 - 1920.000 for this variant.
• Sensitivity: 10 mV/Pa, with typical total harmonic distortion of 0.1 %.
• Battery: 2.2 Ah, 3.6 V BA 40 pack with a typical operating time of 13 h.
• Listed product weight: 208 g.

Charging and remote management

The microphone can be charged with the included USB cable or wirelessly. Wireless charging uses the CHG 2W wireless power transmitter, which is sold separately and is not part of this set. Battery status LEDs on the microphone show remaining charge, so the person running the meeting can check it before starting. The manufacturer states that devices can be monitored and controlled remotely through the Sennheiser Control Cockpit, which can help facilities teams check several units from one place.

Where it fits in Qatar

Three typical settings for this set:

• A ministry boardroom in Msheireb with a dark wood table, where the brown finish sits closer to the furniture and no cable runs to the table surface.
• A training room at a university in Education City where seating changes between sessions, and a cable-free microphone is easier to reposition than a wired one.
• A consultancy meeting room in West Bay holding calls with colleagues in Europe and Asia, where clear pickup from the table matters more than the size of the room.

Planning the installation

Before ordering, decide where the SL Rack Receiver DW will sit and confirm that the GA 4 rack mount kit fits the available rack space. Then choose the microphone position where speakers actually sit. The source data does not list an operating temperature range for this model, so the SmartRooms Qatar team will confirm suitability for the room environment, including heat and dust, before the quotation is finalised. Ask the team to confirm that the 1910.000 - 1920.000 frequency range suits your site. A free site survey is available to check the layout.

Quotations are usually issued within one working day. Send the room size, table shape and number of meeting rooms, and request a quote from SmartRooms Qatar for the Sennheiser SL Boundary Set DW-7 BR.
