Selecting the surround back decoding mode (continued)

How to select the surround back decoding mode

You can select the surround back mode you want according to the input stream.

When you select “AUTO”

When the input stream contains the 6.1 channel decode flag*1, the appropriate decoder is applied to decode the surround back signal.

For the DTS-ES Matrix 6.1 source, DTS Matrix decoder is applied.

For the DTS-ES Discrete 6.1 source, DTS Discrete decoder is applied to reproduce the Discrete 6.1 channel signal.
