To get proper playback of DTS 96/24, the manuel says, "set LISTENING CH SELECT to AUTO or 5.1, choose STANDARD mode and turn off all sound functions." (Page 47. 49TX manuel.) These sound functions include, LOUDNESS, MIDNIGHT, TONE, Digital NR, and the RE-EQ. All must be off. The RE-EQ is found in the THX Audio setup. (page 98 in the 49TX's manuel.) Set the STANDARD RE-EQ to "OFF." For PCM 96/24, set the STEREO RE-EQ to "OFF." The rest (LOUDNESS, ETC.) is found on the 49TX's remote.
