The Wi-DG enables voice control of any supported miniDSP hardware! You need an Amazon Echo for this to work. Setup takes only a few minutes, then you can instruct the miniDSP with basic voice commands.

Use Amazon Alexa and Echo for voice control of a miniDSP


What you need[Top]

See the diagram below for the way this is set up. You will need:

  1. A supported miniDSP hardware unit, and the appropriate plugin running on your computer. See the list of supported hardware/plugins on the Wi-DG product page.

  2. A miniDSP Wi-DG. This tiny box enables the miniDSP hardware to be controlled over the network, and "knows how to talk to" Amazon Alexa.

  3. An Amazon Echo. For this app note, we used the cheapest member of the family, the Amazon Echo Dot, which works just fine. However, you can use any other member of Echo family if you have one.

Follow the instructions in the Wi-DG User Manual to set it up. Important: you need to be using your Wi-DG in Station Mode. Connect things up as shown in the diagram below. If you haven't already, use the plugin to make sure that the Wi-DG and hardware unit are set up and working properly.

Set up your Echo[Top]

(If you have already set up your Echo and have it running on your network, you can skip this section. Note that the Echo and the Wi-DG must be on the same network.)

Go to alexa.amazon.com and log in with your Amazon account. You can then start the setup process for your new Echo:

Getting started with setting up your Echo

Click "Begin Setup" and walk through the process of joining your Echo to your Wi-fi network. The setup process is similar to the way you set up the Wi-DG: join the network that the Echo creates, select your home network, and enter its password. Make sure you join the Echo to the same network that your Wi-DG is on.

After the Echo restarts, it will no longer create its own Wi-Fi network. Your computer may automatically rejoin your home network; if not, use your computer's Wi-Fi settings to rejoin that network.

Install the miniDSP skill[Top]

Reload alexa.amazon.com in your web browser. At the menu on the left, click on "Skills." Enter "minidsp" in the search box and press the Enter key. You should get:

Install the miniDSP skill into your Echo

Click on the miniDSP Controller and then click the Enable button.

Enable the miniDSP skill

Now open another browser window tab or go to http://minidsp-wi-dg.local/alexa. There is a four-digit code:

Get your miniDSP Alexa link key

Follow the instruction there and tell Alexa the link key, by saying aloud "Alexa, tell miniDSP my link key is zero eight four nine" (but using your own link key). The screen will change:

Successful link with Alexa


And that's it! Now you can control the miniDSP with voice commands. The set of commands is basically the same as you can do with the remote:

  1. Alexa, tell mini d. s. p. to mute the device
  2. Alexa, tell mini d. s. p. to unmute the device
  3. Alexa, tell mini d. s. p. to turn the volume up
  4. Alexa, tell mini d. s. p. to turn the volume down
  5. Alexa, tell mini d. s. p. to set preset X [where X is a number from 1 to 4]

That's it for this app note! Have fun, and please let us know what you think of the miniDSP Alexa skill in our forum.
