Drill two additional mounting holes using a 1/8″ drill bit.įor the base plate, you’ll need to drill some holes for mounting the Power Supply Board and Power Transformer. When you’re done drilling the large hole, place your XLR connector and mark the diagonal holes for the machine screws, and drill with a 1/8″ bit.įor the front panel, you can take the easy way and just cut some rectangular openings for the 500 series modules to slide into. Change to a step drill bit, and enlarge the hole to the correct XLR size. First, drill a 1/2″ starter hole using your drill press/hand drill. For the rear panel, you’ll need to drill holes for the XLR jacks, and a square cutout for an IEC AC inlet connector, and the fuse holder.įor drilling the XLR holes, you’ll need a step drill bit to create these holes.
By that I mean, the 6 sides of the rack can be disassembled, that way you can easily drill/machine/cut any hole opening you need on any of the six independent panels. My suggestion is choose a rack that is totally collapsible. You can purchase racks from eBay, Amazon, Par-Metal, Modulo, Hammond, etc. You’ll need a 19″ rack case for this project. Well, you can rack your modules and house them in a 19″ rack! All you need is a power supply, and a little bit of wiring for the input XLR and output XLR connections. Or, you’re just not digging the lunchbox form factor, and prefer a 1u 19″ rack unit.
Even a blank 6-space rack can cost a pretty penny, and you still end up with no modules after purchasing the rack. The problem is you don’t own a lunchbox rack. So let’s say you want to own some 500-series lunchbox modules, could be a mic preamp, compressor, or equalizer unit.
