Sitting quietly at the end of all the data reduction and metadata control parameters is the DP562 Decoder. Its most basic function is returning the compressed AC-3 datastream back into 1 to 5.1 discrete channels of AES/EBU PCM digital or analogue audio.

In addition, the DP562 provides sophisticated monitoring controls, which aid in setting up a monitor system, various listening modes to check downmix compatibility between 5.1, four-channel, phantom center, stereo and mono playback and various output modes to check the results of Dialnorm and dynrng settings.
