Ambient Noise Input Connections Two plug-in barrier-strip connectors on the ANC-1 connect the ambient sensing sources to the device. One or two microphones or line-level sources may be connected (gain adjusted accordingly in the Vocia software interface). Both connections may provide phantom power, switchable from software (default: off). Multiple microphones may be mixed before connecting to the ANC-1.
