The Vanguard Dynamics VAIL Amp is a compact high-performance digital stereo amplifier specifically designed to work with the Amazon Echo Dot (Gen 2) for a custom-installed single-zone audio solution.  Add VAIL Amps and Echo Dots around a home or office for a full multi-room audio, smart paging, and intercom system, while taking advantage of voice control of all Alexa-compatible IOT devices like smart bulbs, light switches, thermostats, and more.  With a second audio source, watch the game and stream music from Echo Dot at the same time, as VAIL Amp can play both sources simultaneously without any need to switch between sources.  Connect the VAIL Amp to any mobile device via Echo Dot’s Bluetooth.

Key Features

  • High-Performance Digital Amplifier 2 x 30Watts
  • 4ohm/8ohm Switchable
  • Provides Power to Amazon Echo Dot
  • 3.5mm Aux Audio Jack for Amazon Echo Dot
  • LINE In for Any Additional Audio Source
  • Subwoofer Output
  • Wall Plate Fits on Any Standard 1-Gang Box
  • Extendable Connections From VAIL Amp to Wall Plate up to 100ft.
  • CAT5 Cable – For Audio Input and Subwoofer Output
  • 16/2 Speaker Wire – For Power
  • 24v Power Supply
  • Paintable Snap-On Square Trim Cover
  • **Amazon Echo Dot (2nd Generation) Sold Separately


The VAIL Amp can be mounted anywhere around a room, in the wall, in the ceiling, on cabinets, or on desks.  We recommend placing the VAIL Amp in the proximity of where voice commands will most often be spoken from.  For example, in a dining room, a great location can be close to the dining table.  Avoid placement on the opposite side of the room.  We also recommend placement height to be the same as your light switches to easily access the Echo Dot as an in-wall keypad.


• OFF – OFF switch for the VAIL Amp is located on the front when installed onto a surface and hidden away once Echo Dot is mounted.

• 4-OHM – Connect any pair of 4 Ohm in-ceiling, in-wall, or bookshelf speakers OR any two pairs of 8 Ohm in-ceiling, in-wall, or bookshelf speakers.  Power LED will turn ON.

• 8-OHM – Connect any pair of 8 Ohm in-ceiling, in-wall, or bookshelf speakers.  Power LED will turn ON.

Note:  Overloading the amplifier with the incorrect impedance or too many speakers may cause damage to the VAIL Amp

Wall Plate

The VAIL Amp wall plate was designed to match seamlessly to your electrical outlets.  Recommended placement of the Wall Plate is next to an electrical outlet for easy access for the power plug.  The wall plate has an analog audio input, subwoofer output, and power plug.  The analog audio input provides a second audio source to the VAIL Amp for your custom speakers.  The subwoofer output provides a convenient location to connect any powered subwoofer to add more bass.  

Note:  Second audio source must have a variable audio output.  The VAIL Amp was not intended for audio sources with fixed audio outputs.

VAIL Amp in wall connectors


The VAIL Amp was designed with flexibility in mind.  The VAIL Amp uses a CAT-5 cable and a 16-2 AWG power cable to connect the VAIL Amp to the Wall Plate.  Extend these common wire standards to mount the VAIL Amp and Wall Plate in opposite sides of the room if desired, up to 300ft, or a remote location like an equipment rack.

VAIL Amp Installation

1.     Prior to actual installation of the VAIL 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 small penciled mounting hole.  Cutting a small hole at an angle first will make drywall repair much easier if necessary.

3.    Once confirmed that there is no obstruction behind the mounting area, finish cutting the hole at a 90-degree angle.

4.      Connect the speaker cables to the speaker output phoenix connector while ensuring polarity with the speakers, + to + and – to – and tighten with a small flat head screwdriver.  Then plug into the back of the VAIL Amp.

5.      Connect the CAT-5 cable and 16 AWG power cable to the back of VAIL Amp and feed through the wall opening to Wall Plate location.

6.      Insert VAIL Amp into wall opening with micro USB and 3.5mm plugs for Echo Dot on the top of the amplifier and tighten the two mounting screws on the front of the amplifier.

Note:  Do not overtighten mounting screws.  This may damage the amplifier, wall surface, or both.

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 small penciled mounting hole. Cutting a small hole at an angle first will make drywall repair much easier if necessary.

3. Once confirmed that there is no obstruction behind the mounting area, finish cutting the hole at a 90-degree angle.

4. Feed CAT-5 cable and 16 AWG power cable through hole and connect to the back of the wall plate.

5. Use provided color-matched screws to secure wall plate to surface or low voltage single gang box or bracket.

Note: Color-matched screws are intended for any in-wall low-voltage single gang box or bracket.

6. Connect any local audio source with variable audio outputs with an analog RCA cable.

7. Connect any powered subwoofer using a subwoofer cable.

8. Connect provided 24v power supply to electrical outlet.

Amazon Echo Dot (Gen 2) Mounting

1. Connect the Micro USB Power Plug to the back of the Amazon Echo Dot.

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 micro USB or 3.5mm cables as this will damage the VAIL Amp.

3. Turn ON VAIL Amp to either 4-Ohm or 8-Ohm setting depending on impedance requirements.

4. Insert Echo Dot at a slight angle with connectors on top in first, then gently push on the bottom to fully mount Echo Dot.

5. Make sure Echo Dot buttons are level to the wall or surface.

6. You may need to adjust the two VAIL Amp mounting screws to ensure that the VAIL Amp is also level.

7. Clip on the trim plate with the four clip points located on the top, bottom, left, and right side of the VAIL Amp.

Note: Do not over-press the clip points. This may damage the amplifier, wall surface, or both.


VAIL Plug Power Supply (PPS) – When replacing in-wall volume controllers with the VAIL Amp, we recommend the PPS to convert speaker cable from the amplifier into injected power cables.
