ltRtSurroundMixLevel property
Specify a value for the following Dolby Digital Plus setting: Left total/Right total surround mix (Lt/Rt surround). MediaConvert uses this value for downmixing. How the service uses this value depends on the value that you choose for Stereo downmix (Eac3StereoDownmix). Valid values: -1.5, -3.0, -4.5, -6.0, and -60. The value -60 mutes the channel. This setting applies only if you keep the default value of 3/2 - L, R, C, Ls, Rs (CODING_MODE_3_2) for the setting Coding mode (Eac3CodingMode). If you choose a different value for Coding mode, the service ignores Left total/Right total surround (ltRtSurroundMixLevel).
