Instant Stereo Downmix
The Downmix hot key allows quick comparisons of 5.1 channel monitoring, a stereo
downmix, or even a mono downmix of channels on an external surround sound
system. Either LtRt or LoRo downmixes are available. Downmix parameters can be
set to either fixed levels or derived from metadata. The same hot key can also be
used to downmix stereo to mono. Refer to How Do I Configure a Stereo
Downmix for My External Surround Sound? in Chapter 3 for details. This
downmix capability is available only for clusters with 6 or fewer channels.
Loudness Monitoring
Loudness can be measured on any cluster with any channel count in the main
screen. When a Cluster Select hot key is pressed to listen to a certain audio
program, Loudness is measured and displayed automatically for that program on
the Main Screen.
Loudness Screen
For more in-depth Loudness measurements, as well as either Continuous or
Start/Stop Loudness measurement control, the Loudness Screen is provided for
clusters with 8 or fewer channels ONLY. It is accessed from the Loudness hot key.
