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 connects the Control Room to VO Live via dedicated steel conduit through Wall 6. Video Studio now operates independently with no fixed signal tie to Control Room.
Cable Routing

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.
Conduit Schedule
All inter-room signal and data runs use dedicated steel EMT conduit. Acoustic sealing is mandatory at every penetration point.
