InadditiontothedirectlineandmicrophoneinputsontheAMP523,additionalwall
lineandmicrophoneinputscanbeconnected.Itprovidesthepossibilitytoconnect
oneadditionalWallLineInput(WLI)andoneadditionalWallMicrophoneInput(WMI).
Tocontrolthestandardfunctionslikeinputselectionandgeneralvolumecontrol,an
additionalMWX43/45wallpanelcanbeconnected.
Theadditionalunitsmustbeconnectedtothe“RS485+AUDIO”RJ45input
