PCM1774: DAC filter necessary?

Part Number: PCM1774
Other Parts Discussed in Thread: DRV135

I want to use 1 line output to connect a wireless audio module and 1 line output to connect a balanced driver DRV135.  Do I add first a DAC filter after the PCM1774 or is the digital DAC filter more then enough for my application.

Application is intercom in a athletics stadium with horn speakers. It is not certainly professional audio equipment for concerts etc...

thanks in advance
