NV-MI1 Mute Interface Adapter (Fig. 15)
The Mute Interface is used in conjunction with System Mute input in the back of the Essentia amplifier. It acts
as a relay for a voltage from up to two phone lines and two doorbell transformers. When a voltage is presented to
the MI1 it then sends a contact closure to the Essentia System, which in turn causes the system to mute momen-
tarily. This is useful in allowing the telephone ring or doorbell to be heard when audio is playing in any of the
zones.
