Worked example
AV — 70V BGM + Paging (Retail)
L-shaped retail sales floor — 70V background-music ceiling speakers on per-zone trunks off an inferred amplifier (no DSP, no codec — speakers-only audio). Paging is ANALOG: an inferred SIP paging gateway / zone amp takes its page source over the LAN and drives the 25V/70V page-zone speakers, with a page-priority ducking association to the BGM amp. One consistent transport — no phantom IP speakers on speaker-level circuits.
