The CSX IRR10 Pocket Receiver from AKG is a reference conferencing infrared receiver that supports up to ten language channels. A large OLED display clearly shows all required information for output volume, channel number and battery status. With two jog dial selectors, you can select the requested channel and adjust the output level to the headphones. A standard 3.5mm stereo jack plug enables the use of any kind of headphones. To charge the AA NiMH rechargeable batteries you can either use a standard USB charger, or the CSX CU50 charging case for 50 units (sold separately).
