    Choosing and Connecting a Loudspeaker Setup Loudspeaker Positions, Naming, and XLR Connectors The Immersive Audio Processor supports many loudspeaker setups, using 2 up to 16 loudspeakers. The figure below illustrates the available 10 horizon- tal, 9 height, and top (T) loudspeaker positions, and a subwoofer (SUB).
  • Page 30 The table below specifies to which loudspeaker positions the 16 XLR output connectors of the Immersive Audio Processor are assigned to. Given are the XLR output number, full channel name, and abbreviated channel name. The XLR output connectors provide a high-quality balanced line-out signal to connect power amplifiers.
  • Page 31 It is recommended that the elevation of the height loudspeakers be in the range 20 to 70 . The Immersive Audio Processor maintains high independence between the loudspeaker signals. The top loudspeaker shall be positioned centrally on the ceiling such that its The result is interference-free audio reproduction, sound reaches the listening area as evenly as possible.
