Audio Snakes & Tie-Lines (BOQ SN-01..SN-04) [AC]

BOQRunQtySpecificationNotes
SN-01SNK-1 — VO Live ↔ Control 8ch XLR multicore1 set8ch analogue loom (Sommer/Klotz) + Neutrik XLR wall plates both ends, SLEEVED through the W6 partitionDubbing/talkback + spare pairs; sleeve packed + sealed both faces (SN-03 detail)
SN-02SNK-2 — Video/Podcast stagebox → Control 16ch multicore1 setWall-mount 16×4 stagebox (Whirlwind Medusa / Radial class) in the Video/Podcast room + 16ch multicore (~15m) to the Control patchbayBand / large-session recording path — bigger-than-VO sources record in the video room, mixed in Control
SN-03Penetration kits for SN-01 / SN-02 / DT-021 lotOversized steel sleeves, OFFSET through BOTH buffer-spine leaves (never a straight-through line), RWA45 packing, acoustic sealant BOTH faces of BOTH leaves, putty pads on every box, escutcheonsTHE critical isolation detail — a badly sealed snake sleeve voids the STC 55 spine. Route under the float floor in EMT; stub-ups cast with the rafts (same rule as EL-04) [AC]
SN-04Control patchbay 48-pt + loom termination1 set48-point patchbay (Neutrik/Whirlwind) + loom termination + labelling, both snakes + tie-linesEvery snake channel lands on the patchbay — no hard-wired dead ends
DT-02SB-01 conduit VO↔Control (dubbing feed)1 setNEW sleeved 32mm steel conduit through W6 — HDMI-over-Cat6 extender, 2 monitorsNEW run — the site is an empty shell (S3-SITE-TRUTH §1); NOTHING exists on site to reuse

Acoustic Wiring Rules [AC]

RuleSpecificationReason
No back-to-back boxesMinimum 600mm horizontal offset across STC-rated partitionsDirect sound path through wall
Putty padsHilti CFS-P PA firestop putty pads behind EVERY box in STC wallsFire + acoustic seal
Box materialSteel boxes ONLY in STC walls — NO plasticPlastic flexes, breaks seal
ConduitEMT steel only — 25mm for data/LV (Cat6A), 50mm for audio multicore. NO PVC on audio runs. 300mm separation between power and signal conduit.EMI/RFI separation
Crossings90° crossings ONLY where power and signal must crossMinimize coupling
Audio cableMinimum CM rated, Mogami W2534 for balanced runsFire rating + shielding
