Set Up Your JustBoom DAC HAT And Case

Section 1 – Board Assembly

Step 1 – Unpack your Raspberry Pi.

Step 2 – Prepare the mounting hardware.

Step 3 – Install the spacers on the Raspberry Pi as shown here holding them with 4 plastic bolts from underneath the Pi.

Step 4 – Place the JustBoom DAC HAT onto the Raspberry Pi by gently pushing the female header onto the Raspberry Pi male header.

If you are also installing the JustBoom AMP then skip to Section 2 – Installing the optional JustBoom Amp.

Step 5 – Screw the last 4 plastic bolts to hold the JustBoom DAC HAT in place.

If you have acquired the JustBoom case for this product please skip to Section 3 – Case assembly.

Step 6 – You can now move onto our OS tutorials section to learn how to acquire, install and configure your favourite Operating System.

If you are planning to use the infrared sensor please follow this guide before you start Section 2.

Section 2 – Installing the Optional JustBoom Amp

The DAC HAT can host the JustBoom Amp which sits on top of the DAC HAT.

The following steps require that have completed Section 1 – Board Assembly

Step 1 – Remove the JustBoom Amp from it’s packaging. You should find:

• 1 JustBoom Amp board
• 4 Metal bolts
• 4 Plastic spacers
• 4 Metal nuts
• 1 Info card
• 1 Roon Labs voucher
• 1 Max2Play voucher
• 2 JustBoom stickers

To install the JustBoom Amp you will only require the 4 metal bolts and the 4 plastic spacers.

Step 2 – Place the small plastic spacers on top of the DAC HAT as shown here.

Step 3 – Align the JustBoom Amp on the DAC HAT as shown here and install the bolts by making sure that the plastic spacers are all well aligned for the bolts to go through.

Step 4 – You have successfully installed the JustBoom Amp on the JustBoom DAC HAT.

Please use a power supply compatible with the specifications above. Check this document for additional information to help you choose the right power supply.

Note that when power is provided to the Amp the Raspberry Pi is back powered and doesn’t require power through the micro USB connector.

Section 3 – Case Assembly

The JustBoom DAC HAT case is the prefect enclosure for the JustBoom DAC HAT and the Raspberry Pi. It has been designed so that is can also accommodate the optional JustBoom Amp.

Step 1 – After removing the protective film pull gently out the two sides of the bottom part of the case to unhook the top.

This should allow you to detach the top cover and easily dismantle the rest of the case.

Within the case you will find 4 rubber feet. Here is how it will look like once opened.

Step 2 – To install the rubber feet on the bottom part of the case you will either have to push and twist them through one of the 4 the holes or help yourself with a small screwdriver to tuck in the top part of the feet within the hole as shown on the left. Be careful not to cut through the feet and rather than using the tip of the screwdriver use the flat surface to push the head of rubber foot in.

Before we get to the next step, if you have any other board than a Raspberry Pi 4B then you will need to push through the cut out where the HDMI connector is.

Step 3 – Once the feet are in position take the Raspberry Pi with the JustBoom DAC HAT and place it onto the left side panel of the case so that the PCBs of the various boards are held within the grooves of the panel as shown in the picture.

Step 4 – In a similar manner place the right side panel on the USB and Ethernet ports of the Raspberry Pi.

Step 5 – By holding the panels in place slide both of them in the bottom part of the case as shown here.

Step 6 – You will notice that the two headphone connectors will stop the assembly from smoothly sliding in. Simply gently pull the side of the case to help the assembly slide in and sit nicely in the bottom part of case with all the connectors properly slot within their respective openings.

Step 7 –At this point you can place the last part of the case on top by making sure that the side panels slide in the grooves of the top part.

Step 8 – As for when opening the case at the beginning, pull slightly the two sides of the bottom part of the case so that the plastic teeth can more easily slide in and hook on to the top part.

Step 9 – Your JustBoom is now ready. Now you can move onto our OS tutorials section to learn how to acquire, install and configure your favourite Operating System.
