RF System Package for Dual Channel Applications

The SR2020-D-US Dual from Sennheiser is a flexible and versatile solution for assistive listening and multi-language applications. It consists of a pair of SR2020-D-US rack-mountable single-channel wireless RF transmitters and 5 HDE2020-D-US stethoset receivers. The system operates in the license-free 926-928MHz radio band, ensuring that you can find a clear communication channel for transmission.

The transmitters can be installed in a standard 19" equipment rack and have backlit LCD displays for relaying vital information. The balanced XLR mic/line inputs let you connect a microphone, mixer, or other audio device. The input also offers 48V phantom power, allowing you to use pro-level condenser mics. A front-panel 1/4" headphone jack provides easy monitoring.

The stethoset receivers have 6 selectable RF channels, which are displayed on the backlit LCD display. The headset has an auto on/off function that is triggered by wearing or removing the headset. The in-ear earpieces provide comfort and noise isolation, while the large rotary volume control makes it easy to adjust the volume. The integrated rechargeable battery provides hours of operation. A carrying case is included that charges the receivers.
