I would like to connect an external Bluetooth microphone at the Z-E3150, but the set does not contain such an microphone?

AW: Connection is possible. The device features an internal microphone located at the front panel. An external microphone can also be connected to the Z-E3150 device. There is a mic input socket on the device backside, for which a spare part called N-ZENC-MIC can be purchased from authorized retailers.
