USERS GUIDE
NERO VOX
ECHO DOT 3
RD
GEN
IN-WALL AMPLIFIER
The NERO VOX was designed for the Amazon Echo Dot 3rd Generation.
CAT-5 cable and a 16-2 AWG power cable are used to connect the
NERO VOX to the Wall Plate. Extend these common wire standards to
mount the NERO VOX and Wall Plate in opposite sides of the room if
desired, up to 300ft, or a remote location like an equipment rack.
The NERO VOX wall plate is designed to match the look of standard
electrical outlets. Ideal placement of the Wall Plate is next to an electrical
outlet for easy access for the power plug. The wall plate has a audio
input, subwoofer/pre output, and power plug. The audio input provides a
second audio source to the NERO VOX. The subwoofer output provides
a convenient location to connect any powered subwoofer to add more
bass.
Note: Any second audio source must have a variable audio output.
4-OHM – Connect any pair of 4 Ohm speakers OR any two pairs of 8
Ohm speakers.
8-OHM – Connect any pair of 8 Ohm speakers.
Note: NERO VOX will automatically go into Overload Protection if the
incorrect impedance is used or too many speakers are connected to
the unit. Maxing out the Gain Control may also trip protection mode. If
overload protection occurs check the gain and/or impedance to resume
normal amp function.

Generation.
2. Connect the 3.5mm audio plug to the audio output on the back
of the Amazon Echo Dot.
Note: Do not forcibly pull on the power plug or 3.5mm
cables,this can damage the NERO VOX
3. Insert Echo Dot at a slight angle with connectors on top in rst,
then gently push on the bottom to fully mount Echo Dot.
4. Make sure Echo Dot buttons are level to the wall or surface.
5. You may need to adjust the two NERO VOX mounting screws to
ensure that the NERO VOX is also level.
6. Clip on the trim plate with the four clip points located on the top,
bottom, left, and right side of the NERO VOX.
Note: Do not use unnecessary force or pressure at the clip points.
This may damage the amplier, wall surface, or both.
ECHO DOT INSTALLATION
1. Prior to installation of the NERO VOX Amp, it is necessary to run
speaker cable to the amplier location.
2. Use the provided cut-out template to align and cut opening. If
you are not sure of potential obstruction behind the mounting area,
start by cutting a smaller hole rst, this will make drywall repair
much easier if necessary.
3. If there is no obstruction behind the mounting area, nish
cutting the hole to the correct size.
4. Connect the speaker cables to the removable speaker output
phoenix connector with correct polarity to the
speakers, + to + and – to – .
5. Connect the CAT-5 cable and 16 AWG power cable to the back
of NERO VOX and feed through the wall opening to Wall Plate
location.
6. Insert NERO VOX into wall opening with power plug and 3.5mm
plugs for Echo Dot on the top of the amplier and tighten the
mounting screws on the front of the amplier.
OPTION: Power Supply – When replacing in-wall volume controls
with the NERO VOX, we recommend converting the speaker cable
from the amplier into power cables for the VOX power supply.
AMP INSTALLATION
1. Choose a location for the wall plate, preferably near an
electrical outlet.
2. Use the provided cut-out template to align and cut opening. If
you are not sure of potential obstruction behind the mounting area,
start by cutting a smaller hole rst, this will make drywall repair
much easier if necessary.
3. If there is no obstruction behind the mounting area, nish
cutting the hole to the correct size.
4. Feed CAT-5 cable and 16 AWG power cable through hole and
connect to the back of the wall plate.
5. Secure wall plate to surface or low voltage single gang box or
bracket using the provided screws.
6. Connect any local audio source with an RCA cable.
7. Connect any powered subwoofer using a subwoofer cable.
8. Connect provided 18v power supply to electrical outlet.
