Thank you for purchasing the Synthrotek ADAPT 1/4 kit!  This is an intermediate build. It is very important to get all the components properly soldered into the PCB in the correct placement. If you feel like you can handle it, please proceed! If not, get some help from a friend with experience or purchase a fully completed unit.

Please build according to the BOMand not these instructions or the pictures alone. Some components may have changed since these were written, or we may not be able to get the exact looking components in the pictures.

1/4 Jacks

Place the 1/4″ jacks int he PCB as shown below.  Make sure that the Stereo Jack is nearest to the 3.5mm jacks.

Use the panel to make sure that you have aligned the jacks in properly.   Turn over and solder.

3.5mm Jacks

The ADAPT 1/4″ uses a stereo 3.5mm jack for the top jack.   You can use 3.5mm mono, banana or RCA jacks.  If you are using 3.5mm jacks, place the jacks in FIRST, then add the panel for proper alignment.  Secure the 1/4″ jack nuts and turn over to solder.  Wait to populate the banana or RCA jacks until your project looks like the photo below.

Optional Banana Jacks

Banana jacks do not have a ground connection.   Secure the banana jack to the panel as shown below and solder a hooked resistor lead to the voltage connection.

Final Project!

The final build will look different depending on which jacks you use.  You are now ready to ADAPT your signals to your desired (or needed!) jack.
