Electrical Infrastructure
Power distribution, outlet positions, the essential SB-01 stagebox, cable routing, grounding, and conduit schedule for the MediaVerse studio zone. All positions referenced to SSOT room coordinates.
Power Distribution Overview
Safety Notice
All electrical work must be performed by a licensed electrician and comply with local electrical codes (IEC 60364 / BS 7671). The studio sub-panel is fed from the building's main distribution board. All circuits use RCD/RCBO protection.

Circuit Schedule
Each room receives a dedicated 16A MCB circuit with isolated ground conductor. All receptacles are Schuko Type F, 16A, studio-grade.
Outlet & Data Positions
All heights measured from finished float floor surface. Power outlets use orange isolated-ground (IG) receptacles in recording rooms. Data outlets are Cat6A S/FTP shielded.

Stagebox Position
One wall-mounted stagebox (SB-01) connects the Control Room to VO Live via dedicated steel conduit through Wall 6. Per S3 BOQ Issue 1, Video/Podcast records locally AND ties to Control by audio: the SNK-2 wall-mount 16×4 stagebox with a 16ch multicore (~15m) to the Control 48-pt patchbay (SN-02/SN-04), crossing the buffer spine only via the sealed, offset SN-03 sleeves.
Cable Routing
Critical Separation Rules
Routing Zones
| Zone | Height / Location | Cable Types | Notes |
|---|---|---|---|
| Plenum | Audio signal cables (XLR, TRS), data (Cat6A) | In dedicated EMT conduit, separated from HVAC ducts | |
| Raised Floor | AC power cables | Power runs under float floor to wall outlets; floor box stub-ups during construction | |
| Buffer Spine | Inter-room conduit (audio, data, video) | Main cable pathway between east and west rooms | |
| Partition Walls | Within wall cavities | SB-01 conduit (32mm steel) | Acoustic sealed both ends; the SNK-1/SNK-2 snake crossings run under the float floor in EMT and cross the spine only via the offset, sealed SN-03 sleeves (S3 BOQ Issue 1) |

Grounding System
Grounding Is Critical for Audio Quality
Ground loops are the #1 cause of hum and buzz in studio installations. The star grounding topology eliminates ground loops by ensuring all equipment grounds converge at a single technical earth point.
Grounding Topology
| Component | Specification |
|---|---|
| Topology | Star ground — all equipment grounds converge at single technical earth point |
| Earth Point | Studio sub-panel (dedicated isolated ground bus bar) |
| Earthing System | TN-S — single-point bond to building ground |
| IG Conductor | Dedicated isolated ground (IG) conductor per circuit |
| IG Receptacles | Orange IG receptacles at all audio equipment positions |
| Room Ground Bars | Isolated ground bus bar in each room, connected directly to panel earth point |
| Ground Lift | Provisions at patchbay for troubleshooting persistent ground loops |
| Shield Drain | Cable shields terminate at source end only (pin-1 lift at destination) |
Acoustic Electrical Rules
Electrical boxes, conduit penetrations, and outlet placements must preserve the acoustic integrity of STC-rated walls. These rules are non-negotiable.
| Rule | Specification |
|---|
Conduit Schedule
All inter-room signal and data runs use dedicated steel EMT conduit. Acoustic sealing is mandatory at every penetration point.
| Run | From | To | Via | Size | Contents | Seal |
|---|---|---|---|---|---|---|
| C-01 | Control Room | VO Live | Partition wall (SB-01) | 32mm EMT | 4x XLR + 4x TRS + 2x Cat6A + HDMI extender | Fire-rated acoustic putty both ends |
| C-02 | Video/Podcast | On-set recorder / camera position | Raised floor / local floor-box stubs | 25mm flex | Local XLR from ST-AFB1 / ST-AFB2 + short-run power / data | Local run — no inter-room penetration on this run |
| C-03 | Video/Podcast (SNK-2 16×4 stagebox) | Control 48-pt patchbay | Under float floor in EMT; stub-ups cast with the rafts; OFFSET steel sleeves through BOTH buffer-spine leaves (SN-03) | 50mm EMT | 16ch multicore (~15m) — S3 BOQ SN-02 | RWA45 packing + acoustic sealant BOTH faces of BOTH leaves + putty pads + escutcheons [AC] |
| C-04 | Sub-panel | All rooms | Under float floor / wall cavities | 25mm EMT | AC power + isolated ground conductors | Acoustic sealant at every box penetration |
Lighting Schedule
Lighting fixtures per room, plus recording indicator lights. All fixtures should support variable color temperature where noted.
