KNOWN ISSUES
(1) Potential issue with stereo PCM sources (typically CD): the HDMI outputs of some Blu-Ray players declare 7.1 channels
instead of 2. In such case, surround and rear channels will not be upmixed. This issue comes from the player, not from the
Altitude
16
. The only solution is to force the player to deliver 2 channels.
(2) Potential issue with 7.1 material: with the Legacy Upmix mode, the “channel remapping” option of the DTS decoder is set to
“off”. The Ls and Rs channels may be missing as the decoder may expect Lss and Rss channels. The best solution is to set the
“channel remapping” to “auto” or to use the Native listening mode.
(3) Potential issue with Auro-3D content: Auro-3D may not be detected in Listening Format Auto. In such cases, the upmixer of
the Bed format will be used. If it is Auto-3D PCM material, the upmixer used will depend on the PCM default layout selected in
the Decoders General Settings. If this happens, selecting Auro-3D listening format will play Native Auro-3D content.
CPU LOAD: Upmixers require a lot of CPU resources, especially in 96kHz, with high channel count. If you are experiencing
any issues while using this kind of configuration, please contact the Trinnov support team to assist you.
Auro-Matic: the Auro-3D upmixer does operate up to 96 kHz but not with higher sampling rates.
Neural:X: The Neural:X upmixer does operate up to 48 kHz but not with higher sampling rates.
* Please refer to the important note below.
For detailed information about the surround upmixers, please contact Trinnov Support team.
IMPORTANT NOTE: Sometimes, in Auto or Native listening format, Auro-3D content may not be correctly detected
and decoded at the input. In this situation, only 5.1 or 7.1 content will be considered. If so, please set the Listening
Format on Auro-3D to ensure the complete Auro-3D decoding. This behavior will be solved in a future software
release.
