Question:  Can I assign both ports of a 4-wire moduleto the same channel on a Helixnet base?  Answer: yes you can assign both ports of a 4-wire module tothe same channel on a Helixnet base.In fact a Helixnet base has 3 expansion slots so if you had3x 4-wire modules installed then you could assign all 6 ports to the samechannel Also if you linked another Helixnet base then you can alsoassign all the 4wire module ports in the 2^nd Helixnet base to thesame chnl on the 1^st Helixnet base   NOTE: you need to take care not to create any external audioloops as this may cause feedback (especially if you are using Helixnet 2-wire PLmodules)
