I'm trying to connect a mixing console to a videoconferencing equipment, to send the audio out of the console to the mic input of the videoconferencing unit. We are talking about a Yamaha MG166cx console and a Tandberg 990 MXP VC unit. The user manual of the VC unit says that the mic input provides a phantom power of 24V and a echo canceling functionality (in which I'm interested). The mixing console manual says that the Aux send is a balanced output and provides these images about it.

The question: is it possible to connect the "Aux send" output to the phantom powered mic input of the VC unit without harming the console?
The manual of the VC unit does not provide details about circuitry.
