Utilizing 558 to 626 MHz in the UHF spectrum, the Sennheiser EK 1039 Gw is a 32-channel Tourguide bodypack receiver offering reliable wireless reception, long battery life, and easy operability for guided tours, assistive listening, and more. With up to 88 MHz of switching bandwidth and 32 factory-preset frequencies, it supports up to 32 simultaneous transmission links for intermodulation-free usage in large installations. Headphones or a 3.5mm plug–equipped induction loop can be connected to the 3.5mm headphone jack for convenient monitoring. Thanks to the HDX compander and wideband frequency response, the EK 1039 delivers highly intelligible speech to the listener. The rugged, compact housing features a backlit display that shows the channel and battery status, and LED indicators for power, low battery, and RF signal. Take advantage of the receiver copy function to quickly configure multiple receivers, and use the lock function to prevent unintended changes to the receiver. Power the EK 1039 for up to eight hours via the included rechargeable battery pack or two AA batteries (available separately).
