ModelNV-MI1
TheNuVoNV-MI1MuteInterfaceModuleisdesignedtoautomaticallymuteanyaudioplayingthroughtheSystem’sspeakerswhen
thetelephoneordoorbellrings.
The MI1 connectsto the NuVo amplifier using a standard
mono patchcable with a mini-plugon each end. Plug one
end into the EXT.MUTE input on the back of the amplifier
and the other end into the input on the front of the MI1.
The back of the MI1 will accept up to two AC or
DC voltagesfrom two differentdoorbell chimes.
This connectionis done with two conductor wire
from the terminalson the doorbellchime to the
DoorbellA or Doorbell B inputs on the back of the
MI1. Polarity is not importantfor this connection.
Up to two phone lines can be brought into the
Rj11 connectionon the back of the MI1. The
voltagefrom the phone ringer will trigger the
NuVo System to mute.

NV-MI1MuteInterruptAdaptor(Fig.50)
TheMuteInterfaceisusedinconjunctionwithSystemMuteinputonthebackoftheGrandConcertoamplifier.Itactsasrelayfora
voltagefromuptotwophonelinesandtwodoorbelltransformers.WhenavoltageispresentedtotheMI1,itsendsacontact
closuretotheGrandConcertoSystem,whichcausesthesystemtomutemomentarily.Thisisusefulinallowingthetelephoneor
doorbelltobeheardwhenaudioisplayinginanyofthezones.
