The XSW-D MINI JACK TX waistband transmitter is part of the Sennheiser XSW-D digital wireless system and is available separately or as a spare if you plan to add a transmitter to your body.

XSW-D MINI JACK TX has a 3.5mm locking microphone-in connector for attaching Sennheiser or Sennheiser via lavalier or headset microphones. This lightweight and compact transmitter can be easily stored in your pocket or neatly wrapped around your waist with a belt (sold separately). Note that it is designed to transmit signals only from the microphone (not the mixer or recorder).
The XSW-D packs premium Sennheiser wireless connectivity into a compact, plug-and-play, one-button digital system that anyone can use. Plug in, plug in and get started, speeding up your workflow so you can focus on creating.

Plug In, Turn On: It Works

• The 1-button, 1-LED concept with single-button interface and status indicator effortlessly handles power and linking tasks for you—without the need for any additional button pressing.

(For optimal results, use of the XSW-D is recommended in environments with limited Wi-Fi / 2.4 GHz traffic.)

Step Up to Sennheiser Sound Quality

• Sennheiser wireless mic systems are an industry standard, prized by professionals for their clarity and reliability. The XSW-D system allows first-time and budget-conscious users to get their hands on genuine Sennheiser sound quality without breaking the bank.

Easy 2.4 GHz Digital Wireless

• Nothing ruins a take like hearing the weather report coming through your mic. Unlike traditional analog wireless systems, the XSW-D digital system operates in the 2.4 GHz ISM band, protecting the integrity of your signal from interruptions and drop outs caused by TV channels, radios, or other sources.
• Thanks to Sennheiser's channel allocation and interference management technology, the system selects the best operating frequency and automatically switches to a clean channel to provide reliable transmission at a distance up to 250' line of sight.

License-Free Operation Worldwide

• Because the XSW-D system operates in the license-free 2.4 GHz band, you don't have to worry about local licensing laws, frequency coordination, and other technical hassles.
• Simply let the system pick a channel for you, and you're ready to get started—whether you're working at home or anywhere in the world.
