16XII. The NV-LRC1 IR Remote ControlThe Essentia System comes with the NV-LRC1 Learning Remote Control. This remote allows wireless control of all keypad functions, aswell as the functions of the audio source equipment. Each NuVo zone keypad has an IR receiver that captures the specific sourcecommands from any remote control and in turn sends the command ultimately to the appropriate source equipment. Embedded IR codelibraries makes use of the LRC1 with a large variety of audio and video equipment easy. For complete setup and functionality refer to theUser Guide included with the remote control. Additional remote controls are available from NuVo.XIII. NV-MI1 Mute Interface AdapterThe Mute Interface is used in conjunction with System Mute input in the back of the Essentia amplifier. It acts as a relay for a voltagefrom up to two phone lines and two doorbell transformers. When a voltage is presented to the MI1 it then sends a contact closure to theEssentia System, which in turn causes the system to mute momentarily. This is useful in allowing the telephone ring or doorbell to beheard when audio is playing in any of the zones, Fig. 17.MUTE INTERFACEADAPTERNV-MI1CONNECT TOMUTE INPUTABABDOORBELL 1DOORBELL 2Connect to Telephone RJ-11Line 1: Pins 3,4 Line 2: Pins 2,5Model NV-MI1Mute Interface ModuleROUTPUT POWER OUTPUT POWER20W/6OHM X2 20W/6OHM X2SYS ONEXT.

Plug oneend into the EXT. MUTE input on the back of theamplifier and the other end into the input on the front ofthe Mi1. The back of the MI1 will accept up to two AC orDC voltages from two different doorbell chimes.This connection is done with a two conductorwire from the terminals on the doorbell chime tothe Doorbell A or Doorbell B inputs on the backof the MI1. Polarity is not important for thisconnection.Up to two phone lines can be brought intothe RJ-11 connection on the back of the MI1.The voltage from the phone ringer willtrigger the NuVo System to mute.
