Control Room Desk Layout

Joinery reference for the DS-01 Control Room production desk — a single 170 × 80 cm Baltic-birch ply / MDF-core carcass with two integrated 8U rack bays (DS-02), an 88-key pull-out tray (DS-03), a raised monitor bridge (DS-05) and the recessed tilted display well (DS-06/DS-07). Drawings on this page are dimensioned to the contractor package (BOQ DS-01..DS-07 + the LEGO build book DESK section); build to those figures.

Plan Geometry

DS-01 carcass 170 × 80 cm — single unit, no return wing

One custom joinery carcass, 170 cm wide × 80 cm deep, dry-set at the Control NORTH wall (VC partition) in the H1r3 local zone 30→200 and facing OW-1. 170 cm is a hard max. End panels are ≤10 cm each so the 150 cm tray aperture holds (170 − 2×10). The desk stands on resilient iso-pads and never touches the wall gypsum.

Owner-supplied equipment on the desk

Shown on the drawings in green so the joiner knows what has to fit. All of it is OWNER-SUPPLIED (see AV Equipment) — not contractor scope, not in the DS-01..DS-07 bands or the budget ladder.

Owner outboard / rack gearDS-02 8U bays16U total across both bays; power lands on the DS-04 loom. Which units land here is NOT yet settled — see the note below
88-key controller (136–146 cm)DS-03 trayUSB bus-powered — consumes no mains outlet
DAW workstation towerFloor, beside the deskFull-tower case does NOT fit an 8U bay; knee space stays clear for tray hardware
Desk power and data are both AT CAPACITY. The DS-04 6-way IG strip runs 5 of 6 ways (display 1 + Genelec 2 + interface/rack 1 + workstation 1), and the second of the two etherCON feed-throughs is consumed by the Control-room camera run (CAM-C / TB-03). No chargers on the desk spur — those live on the EL-06 station — and no daisy-chained strips, ever.
Not scheduled anywhere: SSL UF8, SSL UF1 and the Mackie Big Knob Studio+ appear in no equipment schedule and no BOQ line. They are deliberately absent from these drawings; desk centre is occupied by the DS-06 well.
Rack-bay contents are UNRESOLVED. The three equipment sources disagree on where the outboard lives — the headphone amp in particular is placed in VO Live by the equipment BOM and at the host table / VO position by BOQ TB-07, but sits in the Control-room list on AV Equipment. The 16U of bay capacity is real and built; what fills it is a shop-drawing decision pending the equipment reconciliation, and nothing on this page should be read as fixing it.

Ergonomic Heights

Section on the desk centreline

Work surface 72–74 cm finished (DS-01) — this is the datum for everything else on the desk. The DS-06 well reclines 40–50° with its top edge at 95–99 cm (hard cap ≤108). The 88-key tray parks at ≈66 cm, clear of the ≈70.5 cm surface underside. The owner Genelecs and the DS-02 rack bays are drawn dashed — they sit at the flanks, off this section plane.

Drawing 2b — Recessed tilted display well (DS-06 / DS-07)

Owner-adopted dubbing rig

Tilt band, height cap and the glare keep-out

The lower display sits in a recessed well cut into the desk surface at centre, reclined so the Genelec reflection off the glass is thrown down into the operator zone instead of into the engineer’s ears. Mirror geometry rotates that bounce by 2× the tilt angle, which is why the angle is an acceptance criterion and not a comfort preference.

RuleRequirement
Tilt40–50° recline ONLY. 8–36° is the FORBIDDEN band (bounce lands in the ears). Near-flat ≤7° also rejected — no tilt gives full-panel cloud incidence. ≥38° is fully downward-safe. Measure with a digital angle gauge; do not eyeball it.
Panel24–27" MATTE (anti-glare) — mandatory regardless of tilt. A gloss panel is a rejection. Panel is OWNER-SUPPLIED.
Top edge27" panel (33.6 cm tall) lands at 95–99 cm. HARD CAP ≤108 cm — below the OW-1 sill 110 (VO sightline stays open over the well) and 12+ cm below the 120 cm tweeter axis (direct sound never shadowed).
Well pit≤4 cm below the surface top — any deeper fouls the DS-03 88-key tray envelope (tray top ≈66 vs surface underside ≈70.5).
Footprint25.7 cm at 40° / 21.6 cm at 50°, ≤28 cm allowance → keyboard zone 80 − 28 = 52 cm (≥50 required).
Glare keep-outNO luminaire face within a ~129 cm plan radius of desk centre. Ceiling mirror band = 0.41–1.79 m out from the partition over a ±50 cm lateral band. EL-05 mounts in the REAR-SOUTH half of the Control ceiling.
Upper display (DS-07)Gas-arm that swings fully aside, OR fixed bracket OFFSET EAST toward D3. NEVER centred on OW-1 (a centred eye-level screen sits in the 110→160 window band and blocks the view into VO). Arm clamps to the DS-01 rear spine rail, never the monitor bridge.
Honest limit. The well eliminates the desk-top comb (+0.94 ms, first dip ≈526 Hz) at desk centre only. The flat surface remains at the flanks, in front of each Genelec, so the comb persists on those paths — the IsoAcoustics tilt-back and clear-mirror-zone rules STAND.

Joinery Coordination

Rear spine — loom, feed-throughs and the bay drops

Everything on the desk is strain-relieved into the full-length rear spine: a 6-way isolated-ground strip off the AV-01 spur, two etherCON feed-throughs and one USB pass-through grommet, dropping into the two 8U bays.
