dV-DOSC dV-SUB Manual V3.0 June 2005 46
To power 2-way fill enclosures or 3-way stereo dV-DOSC, ARCS or XT systems using PADO2a and
PADO4a amplifier panels, additional COMB connectors can be employed: 2W(A), 2W(B), 3W(A),
3W(B), SUB(A), SUB(B) or 2W STEREO. DSP output channel assignments for 2-way stereo and 3-way
stereo format presets, CO6 or CO24 patching and COMB connector channel selection are
summarized as follows:

This signal distribution scheme allows for logical patching between digital signal processor outputs and
CO6 or CO24 inputs for 2-way stereo and 3-way stereo format presets, i.e., channels are patched
1:1, 2:2, 3:3 etc. This helps eliminate potential sources of error due to mispatching and, in addition, it
is not necessary to repatch DSP outputs when changing between stereo 2-way and 3-way presets.
