Line 1:
'''Frac Rack''' or simply '''Frac''' is a modular synthesizer format.
Like the [[Eurorack]] format, Frac is considered a [[3U]] format. The height of most modern modular synthesizer modules is measured by the number of vertical units it consumes in a standard [[19-inch rack|19" equipment rack]]. Modules conforming to the 3U format, for example, will take up three vertical units in a 19" equipment rack. Each vertical rack unit is 1
The Frac format has a standard width unit of 1½". So 3" and 4½" wide modules are common in this format. Frac-Rac is an American format designed by John Simonton of [[PAiA]], which has found a wide following largely through the popularity of [[Blacet Research|Blacet]] modules.<ref name="measures" />
Line 7:
Note that even though the height of both Frac and Euro modules are 3U, differences exist in the mounting rails and screws. Thus, each format requires its own mounting system (screws, rails, etc).<ref name="faq">[http://www.blacet.com/FAQ.html Blacet FAQ]</ref>
Frac format modules typically use 3.5 mm connectors and plugs for patching, although there are several companies that offer modules with banana jacks ([[BugBrand]], [[Metalbox]]).<ref>[https://www.muffwiggler.com/forum/viewtopic.php?t=7514&sid=6d5c4caf944e77c085f0437cf90ce3be Banana Frac: The Definitive Guide], Muff Wiggler forum, August 2009</ref><ref>[http://www.metalbox.com/ Metalbox Info]</ref>
Power requirements for Frac modules are typically ±15VDC. Current draw depends on the module.<ref name="measures" /><ref name="faq" />
