Product Description

Managing a fleet of assistive listening receivers is a logistical challenge at scale — the Sennheiser USL29-50-2/NT was engineered to meet it head-on. The case accommodates up to 50 HDi1029-PLL8 or HDi1029-PLL16 receivers in a single enclosure while exposing 20 charging bays at a time for rapid access and simultaneous charging. Operators can use the built-in Copy button to synchronize the channel selection of one receiver to all other units in the case, eliminating the need to manually reprogram each device before an event. Fast charging completes in approximately 2.5 hours, and a trickle-charge mode keeps fully charged receivers topped off without degrading battery health. The case also includes a dedicated charging bay for the SK 2020-D bodypack transmitter and a separate slot for the BA 2015 spare battery, offering a centralized power management hub. Temperature monitoring ensures safe recharging at all times, protecting both the batteries and the receivers from thermal stress. Included with the case is the NT2013-120 power supply, so no additional procurement is required. The USL29-50-2/NT integrates seamlessly with Sennheiser's broader infrared assistive listening infrastructure, making it ideal for ADA-compliance deployments. Its rugged enclosure is designed for repeated daily use in demanding public venue environments. Whether managed by an AV technician or a front-of-house coordinator, this case significantly reduces setup time and operational complexity.
