    VTA PAS  I/O Strip Rewire  Empty VTA PAS I/O Strip Rewire

    I have replaced both boards in the PAS 3 with VTA subs, and am attempting the VTA I/O strip install... It appears phono and pre outs now will ground to their respective boards. does the center of the I/O need separate grounding to chassis / elsewhere?

    Any help appreciated.

    phono ground goes to phono board only
    all other grounds are connected together by the PCB and connect ONLY to the line amp output ground, otherwise you will have ground loops and extra noise
