Amplifier Assignment Planner v11

Wiring rules applied:
· Src = independent audio sources for that row — at the minimum allowed value, the engine piles the max speakers/channel the app guide permits; raise Src to spread speakers across more, thinner sources
· Bi-amp sources drive LF and HF (and LF-2, 3-way) from the same source — never split into separate sources per passband
· Piling more speakers onto one pair/channel than the app guide allows always raises the minimum Src — never silently opens a second pair under the same source, with one bounded exception: a plain single-ended model can pile onto a whole fixed pair (2 channels) from one source on a UXA4807D specifically, using its spare outputs (below)
· No single speaker's passbands span more than one amp
· Bi-amp where the model supports it
· UXA4807D (4 in / 8 out) & UXA4403D (4 in / 4 out): max 4 independent sources/amp either way. A bridged pair (fixed CH1/2, CH3/4, CH5/6, CH7/8 only) spends 1 source for 1 high-power output; a plain SE channel is normally its own independent source, but on an actual UXA4807D one SE source may instead fill a whole fixed pair (2 channels, piled up to 2×/ch) using its spare outputs — bridged, plain SE, and doubled SE can all mix on the same amp
· UXA4401(D): 4 ch, same mixed bridge+SE mechanism scaled down (fixed pairs CH1/2, CH3/4 only) — bridges for the specific models the app guide documents it for, alongside its SE role; never shares a physical amp with the bigger family
· UXA4416: 4 ch, single-ended subwoofers only, never bridges — its own separate pool; cardioid pin-select models (e.g. SB828) claim a whole fixed pair exclusively at alternating per-channel caps
· Amp model auto-optimised to minimise count
