we are a duo, my wife and I; we perform lounge; I want to do away with my old PA and get a PAS; I use a Y2100 and maybe a PA50 and my wife plays guitar; we both sing and we use a digitec VPR for harmonies above our own.
1) we need a small mixer (4 ch) for the mics coz I use the send and return for the VPR thus harmonies are available on all mics; the mixer line out in stereo needs to be connected to the PA.
2)the 2 Keyboards in sterio (L and R for Y2100, and 2 or 4 outputs for PA50) need to be connected to the PA.
3) the guitar (semi acoustic) need to be connected to the PA.
Thus I need 4 channels for instruments.
4)ALso what config of PAS will be most suitable (1 bass module or 2) for lounge.I need a clear sound with balanced depth in the voice and music.
If a PAS in not advisable, what can I use that involves limited number of pieces and ease of transport.!!....(I have to lug it and set up all alone)
