Taken from the Internet: 

The Dolby DP570 Multichannel Audio Tool is a cost-effective, 2-U rackspace unit that greatly simplifies the process of creating Dolby Digital metadata and monitoring multichannel audio. The DP570 interfaces easily with existing audio consoles and workstations, and requires minimal operational effort from the audio professional. The processor also allows the user to hear the effect of metadata in real time, while preparing soundtracks for ultimate delivery as Dolby Digital bitstreams.

“The Model DP570 Multichannel Audio Tool allows program producers to monitor their multichannel programs and easily adjust metadata parameters,” explained Tim J. Carroll, Product Manager, Professional Audio. “This all-in-one product allows exciting, high-impact multichannel audio program material to be created simply by the professional.”

The DP570 accepts eight channels of audio input and processes it according to metadata values chosen by the program creators, including the values for dynamic range compression, dialogue level (dialnorm), and downmix settings. The units feature both digital and analog outputs, along with a metadata output suitable for connection to a DP569 Dolby Digital encoder or DP571 Dolby E encoder.

The DP570 contains all of the necessary features required to augment or replace the monitor section of an audio console for multichannel mixing. Additional features include:

Low-latency monitoring of all Dolby Digital and Dolby Surround listening modes without requiring external encoders or decoders
Eight-channel router for channel reconfiguration of program material delivered with nonstandard track layout
Fast, accurate measurement and alignment of dialogue level (dialnorm)
Separate multichannel, stereo, and mono outputs for feeding three sets of monitor speakers
Custom reference-quality 24-bit digital-to-analog converter modules
Highly flexible Ethernet, RS-485, and GPI/O control
