The Sennheiser EM-XSW 2-B is a compact UHF diversity receiver for the XSW 2 wireless system, operating in the B-band (614–638 MHz) with BNC antenna inputs, XLR and 1/4″ jack balanced outputs, and NT 12-5CW power supply included. Designed for reliable vocal/instrument transmission, it features automatic frequency management, up to 12 compatible channels, and OLED display for easy setup in live sound or presentations.
The Sennheiser EM-XSW 2-B UHF receiver forms the core of the accessible XSW 2 wireless system, delivering professional-grade performance for singers, presenters, and instrumentalists with its true diversity reception—switching seamlessly between dual BNC-connected antennas (50 Ω, up to 50 m range) to minimize dropouts in dynamic environments like stages or conference halls. Tuned to the B-band frequency range (614.000–638.000 MHz, 24 MHz bandwidth), it supports up to 12 simultaneous channels with automatic scan and sync functions, ensuring interference-free operation via infrared pairing with handheld or bodypack transmitters. The rugged metal housing (8.4 x 1.7 x 8.0 inches / 214 x 42 x 202 mm, 1.3 lb / 0.6 kg) withstands touring demands, while the intuitive OLED display provides real-time metering for RF signal, AF level, and battery status. Outputs include balanced XLR (mic-level, -18 dBu nominal) and 1/4″ TRS jack (line/mic switchable, +12 dBu max) for direct integration with mixers or PAs, with adjustable squelch (3–28 μV) and pilot tone (32.768 kHz) for secure muting. Powered by the included NT 12-5CW external PSU (12 V DC, 500 mA), it operates quietly (<2.5 dB noise floor) with low latency (<3 ms), making it ideal for entry-level wireless setups in houses of worship, education, or small venues seeking Sennheiser reliability without complexity.
