L-Acoustics V-DOSC - Figure 30: L-ACOUSTICS Rk122 A Amp Rack Channel Assignments for 2-Way, 3-Way Stereo Presets; Table 8: 2-Way, 3-Way Stereo Preset DSP Output Channel Assignment and COMB Connector Summary

L-ACOUSTICS V-DOSC Manual Version 4 6/29/2005 Page 47 of 158
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 / 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.
Operating modes, amplifier rack channel assignments and cabling plus loudspeaker enclosure
combinations for the L-ACOUSTICS RK122a amplifier rack (PADO2a plus 2 x LA48a) are as follows:
