What we need

---

• Raspberry Pi A+/B+/2/3B/3B+/4B
• DACBerry PRO+ for Pi
• A MicroSD Card
• Set of 4 Nylon M2.5 Screws
• Set of 4 Nylon M2.5*11mm Female to Female Standoffs
• Set of 4 Nylon M2.5*5mm Male to Female Standoffs

Assembly

---

Use the nylon screws and standoffs to assembly the Raspberry Pi together with the DACBerry AMP² SE, as shown on the image below:

Onboard Configuration

---

By default, the DACBerry AMP² SE board DAC PCM5242 acts as master device, and the Pi as slave device.

Board layout

This is the board layout:

 

SDB™ Connector

---

DACBerry AMP² SE is one of the first boards to include this standard created by OSA Electronics. SDB Interface is a mix Serial Data signals together in the same Bus.

The A2 revision uses SDB™ 1.2.

Quick Install

---

There is an easy way to install support for AMP² SE on Raspbian/Raspberry Pi OS.

Just run the following code from your Raspberry Pi with Internet connectivity:

You may need to reboot once. After rebooting, everything should work!

*NOTE: If quick install doesn’t work at all, or want to follow step by step instructions, please refer to the Retropie part.

Volumio Instructions

---

Volumio has already official support for this board, so to get it working you need to use the “Hifiberry DAC Plus” profile, what is fully compatible with AMP² SE.

*IMPORTANT: In order to make it works properly, is recommended to do a fresh install of Volumio and use lastest version.

Airplay

Volumio is a perfect choice if you want to stream music from your Apple devices.

Step 1
Open Volumio and navigate trought “Network” in Settings Panel, and connect to your WiFi network.

Step 2
Inside “Network” settings, locate “Hotspot Settings” tab and enable it if it’s not. Restart.

Step 3
Go to your desired Apple (or Windows) device and open iTunes if you are using a computer, or open the “control center” if using a phone/tablet. Go to the “Airplay” icon and select “Volumio”.

Step 4
That’s it! Enjoy streaming music!

Adding password to your Airplay device

With the Airplay feature activated, everybody will have access to your device and will be able to play music on it. If you want to add a password to it, follow these instructions.

Step 1
Open an SSH connection to your Pi, if you can’t connect at all, enable it on volumio.local/dev.

Then, type the following line to open up the template for the shairport config file in a text editor:

Step 2
In the “general” section, add a password, like this:

Save the file as usual and reboot.

Step 3
Connect to your device, you should be prompted for a password when airplaying to it.

moOde Instructions

---

moOde Audio Player is one of a range of audio playback solutions that supports DACBerry boards. You can follow these instructions in order to install and configure it.

It does not offer a “ready to use” image like other distributions. Instead it uses an image of the operating system (Raspbian) as basis and then a script for automatic installation.

*IMPORTANT: In order to make it works properly, is recommended to do a fresh install of moOde and use lastest version.

Installation

The following command executes the script. If you have not been connected to the internet two commands earlier, than simply NOTHING will happen here. If you had been online the installation wizard will be started.

Now a wizard will help you to do some setup:

Make the following choices:

• Write OS build directly to the boot SDCard? -> y
• Do you have a backup of your boot SDCard? -> y
• Enter Current Date (YYYY-MM-DD) -> enter date
• Make corrections -> n
• Use a proxy server for Internet access -> n
• Use a WIFI instead of Ethernet? -> n (Switching to WIFI should be done later when moOde is running.)
• Proceed with build -> y
• Power off the Pi -> y
• Wait for about 10 seconds until the green LED on Pi stops blinking. Then unplug the power cable and replug it.

All you have to do now is to wait. The Pi is downloading and compiling, so how long you have to wait is mostly depending on the CPU speed of your Pi. This may be several hours.

Configuration

Step 1
Direct your web browser to http://moode, http://moode.local or the device’s IP address. Then, click the menu icon in the top right corner and select Configure.

Step 2
Now, select the Audio icon. Choose the HiFiBerry DAC+ board from the I2S audio device drop-down list and click SET.

Step 3
Restart the device and enjoy your music!

OSMC Instructions

---

KODI OSMC team is already working to add official support on next release, but meanwhile, you can follow these steps to make it work:

*IMPORTANT: In order to make it works properly, is recommended to do a fresh install of OSMC and use lastest version.

To get it working using the RCA Output and Optical/Coax at same time, you need to use the “Hifiberry DAC Plus” profile.

Retropie Instructions

---

As for Raspbian Jessie, just run the following code from your Raspberry Pi with Internet connectivity:

The next step is to edit the raspi modules list with:

This file should be blank! Just copy and paste the following text into the file:

Save the file as usual and reboot:

Now to check everything is as expected, just type:

You should see something like that:

And voilà! Enjoy playing retro games!
