For camera operators who want to monitor with stereo headphones an optional 3.5mm to XLR cable is available that allows the second output of the splitter to be connected to the second microphone input of a camera. The operator can then hear the talents microphone and the IFB feed using the camera's monitoring system.

Power Requirements
Remote Talkback operates from its own 9 - volt battery. Remove the rear battery cover to access.
2.5 mm Plug and Cable
The attached cable and three conductor 2.5 mm plug is compatible with devices that accept a generic 3rd party universal hands free headset. The tip is the microphone, the ring is the mono earpiece and the sleeve is ground.
While some cell phones have a 2.5mm jack others require an adapter to convert their connector into a 2.5mm jack.
Remote Talkback does not work with stereo cell phones, which use a four conductor 2.5mm plug or walkie-talkie type phones even in cell phone mode.
