Using the Equipment
• 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.
3.14.4.4.9 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.
• 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.
3.14.4.4.10 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.
• 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
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.
