Our customer has questions about TPA3118D2.
I'm posting the questions for the customer:
++++++++++++++++++++++++++++++++++++++++++++++
We are developing a loudspeaker system for announcement in a building.
Our system is connecting as below;
TPA3118D2(PBTL) monaural output -- LC output filters --
Audio Transformer(converting Balance to Unbalance) --
long cable(100-200meter) -- Speakers(Single-End, 20ohm x10 in parallel)
We have some questions;
1)Does the transformer offer the function of EMI measures ?
2)Are there any problems or anxious matters by using a transformer?

Thanks in advance.
Best regards,
Takishin
