RX Emergency
You find yourself out of inputs on your Sound Devices™ field mixer and need a way to get one more wireless into the Mix…
The RX EMERGENCY is a modular interface that allows an additional wireless line level signal to input into a Sound Devices™ mixer via the Mix Bus effectively adding a channel to your mixer when in a jam - hence - RX EMERGENCY. The box's small size allows you to save precious bag space while still having complete control over the wireless level and Left, Right or both assigns in the stereo mix with transformer isolation.
The RX EMERGENCY was designed for the production sound professional. It's small, light and field durable. We offer a full complement of high quality cables to link up popular wireless receiver outputs and Sound Devices™ three, four and five channel field mixers with the RX.
The box ergonomics and connector orientation have been carefully selected to seamlessly integrate into your existing bag setup without impeding the placement of your audio gear. All Cable Techniques products are carefully hand assembled in the United States using premium materials and built to the exacting standards of production sound professionals.
