Mute Interface Module
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 connects to the NuVo amplifier using a standard
mono patch cable with a mini-plug on 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 voltages from two different doorbell chimes.
This connection is done with two conductor wire
from the terminals on the doorbell chime to the
Doorbell A or Doorbell B inputs on the back of the
MI1. Polarity is not important for this connection.
Up to two phone lines can be brought into the
RJ-11 connection on the back of the MI1. The
voltage from the phone ringer will trigger the
NuVo System to mute.

NV-MI1 Mute Interface Adaptor (fig. 16)
The Mute Interface is used in conjunction with System Mute input on the back of the Essentia 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.
