6.2 Typical Tasks
A chief purpose of the DP570 in a live remote environment is to provide downmixing
emulation, which includes the ability to invoke what is commonly referred to as Late Night
mode in consumer home theater equipment. For example, you can quickly assess if the
announcer’s voice during a live event will be drowned out when the original 5.1 audio
channels are downmixed to a stereo signal, by simply clicking Stereo and RF for Late Night
mode emulation in the Downmix section of the remote application, as shown in
Figure 6‐2 .
