Manual revision pertinent to the V1.10 Software upgrade:
Page 3-22: Format Detection Parameter description
The format detection parameter does not apply to the Dolby PLIIx family of listening modes.
The Format Detect parameter is independently adjustable for each input. It was implemented to correct
anomalies in certain mixed audio format and satellite broadcast signals. Within the V1.10 software
upgrade, if you require the FAST FORMAT DETECT setting for one of your inputs, you should avoid using
PLIIx listening modes with that input.
