Can I use Xeo as a rear speaker?

Xeo can be used effectively as a wireless rear speaker (or front speaker), if a Xeo Transmitter / Hub / Connect or Xeo 2 is connected to the analog rear (or front) pre-out outputs of the surround receiver. 

Theoretically, several Xeo Transmitter / Hub / Connect (set to ID A, B and C) or Xeo 2 can be connected to the front, center and rear outputs of the sound receiver, although the simultaneous use of multiple transmitters usually leads to sound dropouts, depending on the utilization of the wireless network and is therefore not recommended.
