Multichannel and two-channel output

A product with a Dolby Digital Plus decoder can provide a variety of outputs, multichannel or two channel.

The test procedure questionnaire will request information about which output is considered the preferred output. The questionnaire will use this information to provide test instructions for this main output for all applicable tests. This can be any output at the preference of the tester. We do, however, recommend that you always use the maximum output channel configuration supported by your product to run each test case. If two-channel output is selected, make sure all channels available in test streams are correctly downmixed and clearly audible in the two-channel output.

This section provides expected channel routing by two-, 5.1-, and 7.1-channel products when playing the channel identification test signals.
