How are SP Portable and Touring Packs broken out by Phase?
Below are breakdowns for each portable pack ETC makes. In the newer Touring Packs the phasing is also detailed by the color coding in the patch bay. Black For Phase A, Red for Phase B, and Blue for Phase C. Note that these dimmer #s assume each module holds two dimmers and takes up only one module space in the rack (e.g. a rack populated with D20 modules).
An SP6 spaces 2 Modules per phase
An SP12 Spaces 4 Modules per phase
An SP24 (small Touring Pack) Phasing spaces a bit differently. There are 8 Modules per phase but they are split into 2 smaller bus bars per phase of 4 modules each
An SP36 (also Known as the Bandit Rack)
In this rack there are 12 modules per phase splits into 3 smaller bus bars per phase except for phase B which has 4 smaller bus bars 2 with 4 modules and 2 with 2 modules
Dimmer 33-36 (Bottom of column 1)

An SP48 (Large Touring Pack) Has 16 Modules per Phase split into 4 smaller bus bars per phase of 4 modules each.
