Audio Decoder > Down-mix Method
This field specifies the Down-mix Method for a specific Audio Decoder. The Down-
mix Method is applied only to AC-3 5.1 and AAC 5.1 audio formats so that the audio
output is mixed to a stereo pair (2/0). The Low Frequency Effects (LFE) channel is
ignored in both down-mix methods.

Audio Decoder > AAC Down-mix Algorithm
This field specifies the AAC Down-mix Algorithm to be applied for a specific Audio
Decoder. This is only applicable for the AAC audio format.
This feature is only available with the Advanced Audio Decoder devices and
therefore only the RX8200.

3.14.4.4.11
Audio Decoder > Enable PTS Synchronization
This field specifies whether to synchronize the audio stream being decoded for a
specific Audio Decoder.
If enabled (default), the PTS from the audio stream is synchronized to the STC/PCR
maintained by the decoder in which case, lip-sync is maintained and the decoder
may skip or repeat audio frames.
If disabled, the decoder does not attempt to synchronize the audio frames.

MIXED TO BOTH – Channel 1 and Channel 2 are mixed and both output on the
left and right.
LEFT TO BOTH – Channel 1 will output on the left and right. Channel 2 is
dropped.
RIGHT TO BOTH – Channel 2 will output on the left and right. Channel 1 is
dropped.
SURROUND STEREO – This stereo down-mix method is the same as Left
total/Right total (Lt/Rt). This is where the different channels are processed
before summing them together and is suitable for processing by a Surround
Sound decoder to provide a rear Surround signal.
CONVENTIONAL STEREO – This stereo down-mix method is the same as Left
only/Right only (Lo/Ro). This is where the different channels are simply summed
together with the centre channel added to both left and right outputs.
ISO13818 – Use the down-mix equations defined by ISO/IEC 13818-7
ARIB B21 – Use the down-mix equations defined by ARIB document STD-B21
