I have now purchased the following two items: RØDE Wireless GO: https://www.digitec.ch/de/s1/product/rde-wireless-go-videografie-reportage-mikrofon-10938423 RØDE Lav: https://www.digitec.ch/de/s1/product/rde-lav-videografie-mikrofon-11806003 I have plugged the Lav (microphone) into the TX transmitter from the Wireless GO, but it does not receive any sound. The RX receiver recognises that the TX transmitter is connected and also receives its voice input via the internal micro-phone. But when the RØDE Lav is connected, there is no more audio input. Are the two items really compatible together?
