Upgrade (Auro-3D)

Auro-3D sound mode

Sound mode type

This mode uses an Auro-3D decoder to create three-dimensional audio output using the Height Channel. It is ideal for

playback of signals encoded as Auro-3D with a Height Channel. If signals not encoded as Auro-3D are input, an Upmixer

called the Auro-Matic is used to create highly realistic three-dimensional audio output.

Auro-2D Surround

This mode uses an Auro-3D decoder to create Surround Sound without a Height Channel. It is ideal for playback of signals

encoded as Auro-3D without a Height Channel. If signals not encoded as Auro-3D are input, an Upmixer called the Auro-

Matic is used to output Surround Sound.
