HARDWARE – STANDOFFS
Your DIY500 mkII Minimal Kit included a bag of hardware. From it, locate (4) 1″ hex standoffs, (4) 1/4″ hex standoffs, and (4) lock washers. They will connect through the four holes in the DIY500 mkII PCB, creating a framework on which to mount the module enclosure side panels. Proceed according to the following photographs.

Fig. 89 Locate and assemble these pieces of hardware

Fig. 90 The longer hex standoff goes through the lock washer and the top of the PCB, screwing into the shorter hex standoff on the bottom of the PCB. Do not over-tighten. Finger tight is adequate.

HARDWARE – FRONT PANEL
It’s time to install the front panel and accompanying control hardware. Locate a second bag containing black components and proceed as follows.

Fig. 97 Two black screws, a black plastic nut, and a 1/4" metal nut are used to attach the front panel to the XLR connector, 1/4" connector, and gain pot.

Fig. 98 Carefully tighten the 1/8" gain pot panel nut without scraping the front panel finish.
