    The result is potential hum and noise induced when using standard insert cables. To eliminate this noise the C400XL has special designed ground sensing inputs and outputs, which are "enabled" by using a ground-sensing split cable.
  • Page 15 CABLES Type 3 Unwanted hum and noise can be introduced if you connect the outputs of C400XL to unbalanced equipment using a standard XLR to TRS (type 3a). If this is the case it is most likely because the ring-connection is floating/unconnected inside the device you are connecting to.
