Wireless XLR Base Set for Vocals

The Sennheiser XSW-D Wireless Digital XLR Base Set replaces a microphone cable with a 2.4 GHz digital link. It includes an XLR female plug-on transmitter and an XLR male plug-on receiver that pair automatically with one-touch ease. The system delivers a frequency response of 80 Hz to 18 kHz and latency below 4 ms using the aptX Live codec.

Suited for Stage and Speech

Singers, presenters and AV crews who need cable-free movement on stage or in a venue will benefit from the 250 ft (76.2 m) line-of-sight range and up to 5 hours of battery life per unit. Users who require rack-mount diversity receivers, multi-channel coordination or phantom power for condenser microphones should look at other systems.

Quick Plug-On Installation

Attach the transmitter to any dynamic microphone XLR output and the receiver to a mixer or PA input, then press the pairing button to link them. The main issues are forgetting to charge both units before a show, placing the receiver behind metal structures that block the 2.4 GHz signal, or exceeding the single-pair limit in dense RF environments.

Highlights

  • Crystal-clear audio from 80 Hz to 18 kHz frequency response

  • Stable wireless link on 2.4 GHz up to 250 ft (76.2 m) line of sight
  • Up to 5 hours continuous use per charge for transmitter and receiver
  • One-touch automatic pairing for instant cable-free setup

Questions about this item

What type of microphone does the XLR female plug-on transmitter connect to?

The transmitter plugs directly onto any dynamic vocal microphone with a standard male XLR connector, so you must already own such a microphone for the set to work.

Will the 2.4 GHz wireless link interfere with older analog wireless microphone systems I still use?

The set operates digitally on the 2.4 GHz band, which is separate from typical UHF or VHF analog wireless frequencies, so it will not interfere with those older systems.

How can I confirm the transmitter and receiver are paired and transmitting audio after setup?

After the one-touch automatic pairing, check that both units show a solid connection status and listen for audio with the specified 80 Hz to 18 kHz frequency response and less than 4 ms latency.
