Product Overview
The Sennheiser EM-XSW 1 DUAL-A is a dual-channel antenna-switching diversity receiver set for the XSW 1 platform, designed for installations and venues that need to receive two simultaneous XSW 1 wireless channels from a single rack or tabletop unit. The set operates in the A frequency range (548–572 MHz) and supports up to 10 channels per receiver within the available bandwidth. It is sold as a dual receiver set — two EM-XSW 1 receivers — allowing integration with any XSW 1-compatible handheld or bodypack transmitters.
Product Description
The EM-XSW 1 DUAL-A provides an economical path to dual-channel wireless reception on the XSW 1 platform without purchasing two separate receiver sets. Each EM-XSW 1 receiver in the set uses antenna-switching diversity with integrated antennas to reduce RF dropouts in standard single-room environments. Both receivers operate independently, allowing frequency coordination across up to 10 available channels per receiver in the A band. The dual configuration is well-suited for two-microphone setups such as a presenter lavalier paired with a backup vocal handheld, or two independent vocal channels at a podium or altar. Infrared sync on each receiver allows rapid channel pairing with any SK XSW-A bodypack or SKM 825/835/865-XSW handheld transmitter. Front-panel displays on both units show RF level, AF level, and battery status. The NT 12-5 CW power supplies are included. The EM-XSW 1 DUAL-A is the correct choice when two XSW 1 channels are needed and a complete second set with transmitters is not required — for example, when transmitters are purchased separately or when upgrading receivers in an existing XSW 1 installation.
