OSD Nero VOX - Echo Dot 3rd Gen In-Wall Amplifier Manual

OVERVIEW

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.

SYSTEM DIAGRAM

WALL PLATE 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 first, this will make drywall repair much easier if necessary.
3. If there is no obstruction behind the mounting area, finish 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.

WALL PLATE TEMPLATE

AMP INSTALLATION

1. Prior to installation of the NERO VOX Amp, it is necessary to run speaker cable to the amplifier 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 first, this will make drywall repair much easier if necessary.
3. If there is no obstruction behind the mounting area, finish 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 amplifier and tighten the mounting screws on the front of the amplifier.

OPTION: Power Supply – When replacing in-wall volume controls with the NERO VOX, we recommend converting the speaker cable from the amplifier into power cables for the VOX power supply.

ECHO DOT INSTALLATION

1. Connect the Power Plug to the back of the Amazon Echo Dot 3^RD 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 first, 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 amplifier, wall surface, or both.
