The following specs must be taken into account while selecting the chain
1. The typical output from a CD/DVD player is 200 mV
2. A Hifi pre amp boosts the signal from a CD player to 0.7X V
3. The average input sensitivity of a Hifi power amp is around 1V
4. The average input sensitivity of a PA or commercial power amp is around 1.4 V
(Now a days crown is selling some models like XLS and XLi series which has a selectable input sensitivity of 0.77 and 1.4 V)
You need to find out the output of the DAP before going forward
