Thank you for your comment,for me the P2 it’s an upgrade from analogue mixer + laptop and microphone wireless receiver and this echo/reverb additional option could be helpful.In our country not especially at wedding events but for some normal parties it’s a fact that some of the guests want to sing some notorious songs for funny and these effects are a must in such as situations.I have to stay for the moment to analyse and take the proper decision.Thank your again for your support.
