Sennheiser SL Lavalier

The Sennheiser SL Lavalier requires a connection to a wireless transmitter system, such as the Sennheiser XSW or Evolution series, rather than plugging directly into a smartphone. You will need a receiver plugged into your recording device to capture the audio. This setup is designed to ensure professional broadcast-quality sound without relying on consumer-grade cables.

It typically uses a locking 3.5mm (1/8") connector, often wired to Sennheiser's proprietary standard for their EW series bodypack transmitters. You should verify the exact pin configuration to ensure it matches your specific Sennheiser transmitter. Adapters are available if you need to transition to a different wireless ecosystem.

No, lavalier microphones like the Sennheiser SL do not use standard phantom power because they are electret condenser mics designed for low-voltage plug-in power. The necessary power is supplied directly by the wireless bodypack transmitter it connects to. Supplying 48V phantom power directly to the mic capsule could permanently damage the element.

Yes, it is suitable for outdoor use, but you must use a foam windscreen or a dedicated furry windjammer over the capsule. Without additional wind protection, the microphone will pick up unwanted popping noises from wind hitting the diaphragm. Sennheiser usually provides a basic foam screen in the box, though heavier winds require aftermarket protection.
