WIRELESS AUDIO FOR VOCALS AND SPEECH
This complete single-channel set combines the SKM 825-XSW handheld transmitter with its dynamic cardioid e825 capsule and the EM-XSW 1 stationary receiver. It suits live vocals, hosting and presentations where quick setup and intelligible voice transmission matter.

The receiver uses antenna-switching diversity reception. Automatic frequency scanning and synchronization via a remote channel simplify setup; the system supports up to 10 compatible channels in the relevant frequency range.
The receiver’s rear panel provides a balanced 3-pin XLR and an unbalanced 6.3 mm jack output. A Mic/Line switch lets you select the level for the connected equipment. Sennheiser recommends using only one of these audio outputs at a time.
