The Sennheiser SK-XSW-B Band is a compact UHF bodypack transmitter for XSW1 and XSW2 wireless systems, operating in the B-band (614–638 MHz) with an electronics warfare connector and 2 AA battery power. Designed for instruments, lav mics, or headsets, it delivers reliable transmission up to 100 m with automatic frequency management and up to 8 hours of runtime—ideal for live performances, presentations, or ENG.
The Sennheiser SK-XSW-B Band bodypack transmitter is a versatile, user-friendly component of the XSW1 and XSW2 wireless series, providing seamless integration for vocalists, musicians, and presenters requiring freedom of movement without compromising audio quality. Tuned to the B-band frequency range (614.000–638.000 MHz, 24 MHz bandwidth), it supports up to 10 compatible channels with automatic frequency scan and IR sync for quick setup, ensuring interference-free operation in diverse environments like stages, classrooms, or houses of worship. The lightweight metal housing (3.8 x 2.5 x 0.9 inches / 97 x 63 x 23 mm, 185 g with batteries) features a secure locking 3.5 mm jack for lavalier or headset mics, with adjustable input gain (-20 to +20 dB) and pilot tone (32.768 kHz) for dropout-free transmission up to 100 m line-of-sight. Powered by 2 AA batteries (up to 8 hours runtime, low-battery indicator), it includes an ”electronics warfare” connector (likely a secure locking 3.5 mm for robust cable retention). The intuitive OLED display shows RF output, battery status, and mute settings. Compatible with EM-XSW receivers, it excels in delivering transparent, low-latency audio (<3 ms) for instruments, speech, or vocals, making it an entry-level yet professional choice for reliable wireless performance.
