         Please note , in Bi-amp mode, your speakers must have the real bi-wires design.
         In our experiences, some speakers even have the 2 groups inputs but they just simply connect as normal 1 groups input.
         We are advice you test your speakers if had the real bi-wires input before purchase the Precision 3 .
         Test method: 
         Usually the speakers have the cooper jumpers connect between two groups inputs, take off the jumpers let the one groups without any connect, if the speakers lost some sound, your speakers are the real bi-wires connect.
          You can not connect the bi-amps to a fake bi-wire speakers,  that will damage the amps and lost the warranty.
          In case , you can connect one Precision 3 working for one speaker, the Right output connect to bass and left output connect to tweeter .
          In our experience, bi-amp can sound better than some electric frequency divider .
