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 up-mixed. This issue comes from the player,
not from the SDP-75. The only solution is to force the player to deliver 2 channels.
(2) Potential issue with Auro-3D content: Auro-3D may not be detected in Listening Format Auto. In such cases, the up-
mixer of the Bed format will be used. If it is Auto-3D PCM material, the up-mixer used will depend of the PCM default
layout selected in the Decoders General Settings. If this happen, selecting Auro-3D listening format will play Native Auro-
3D content.
CPU LOAD: Do not forget that Up-mixers require a lot of CPU resources, especially in 96 kHz with high channel count.
Auro-Matic: The Auro-3D up-mixer does operate up to 96 kHz but not with higher sampling rates.
Neural:X: The Neural:X up-mixer 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 up-mixers, please contact the JBL Synthesis 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.
