DS-01 Control Production Desk — Build Specification

Type C — Construction Guide · Local joinery (Damascus, birch ply imported via TR) · Baltic-birch ply / MDF-core carcass

Overview

The Control Room desk is DS-01 in the contractor package: a single custom joinery carcass, 170 cm wide × 80 cm deep, Baltic-birch ply / MDF-core, with a 72–74 cm finished work surface, a raised monitor bridge, two integrated 8U rack bays (DS-02), an 88-key pull-out tray (DS-03), a full-length cable-management spine and the recessed tilted display well (DS-06/DS-07).

Fabrication location: Damascus local joinery (Baltic birch imported via TR). Rack rails, sliders and mounts are imported hardware — see the DS-02/DS-03 brand calls below. Shop-built and delivered through D5.
This page governs fabrication; DESK-LAYOUT governs geometry. Both are dimensioned to BOQ DS-01..DS-07 and the LEGO build book (DESK section). Where anything on this page disagrees with the contractor package, the package wins — raise it as a shop-drawing item, not a site decision.

One unit, not an L. The desk sits at the Control NORTH wall (VC partition) in the H1r3 local zone 30→200 — 170 cm is a hard maximum, not a target. The ≤10 cm end panels are load-bearing on the spec: they are what allows the 150 cm tray aperture, which is what allows an 88-key controller (136–146 cm) to fit.

Do NOT add a return wing, and do NOT exceed 170 cm overall. The zone is bounded by the NW full-trap face and D3 clearance; a wider desk fouls one or the other.

Carcass & Pedestals

DS-01 / DS-02

Specifications

ParameterValue
Carcass materialBaltic-birch ply / MDF-core (per H1r3 spec) — furniture-grade joinery
Overall170 w × 80 d cm; end panels ≤10 cm each
Pedestals2, one at each end, each carrying an 8U rack bay
Rack rails (DS-02)Penn Elcom R0863 rack strip or Adam Hall 61535 + cage nuts + tie bars
Bay ventilationVentilation slots at the REAR of each bay
Floor contactResilient iso-pads under ALL feet + levelling

Assembly Notes

  • The two 8U bays go in at carcass stage — retrofitting rails into a closed pedestal never sits square
  • Knee space between the pedestals stays clear for the DS-03 tray hardware
  • Rack top lands at ≈45.6 cm (10 cm plinth + 8U); the DS-03 tray slides above the bays at ≈66 cm
  • Shop-built and delivered through D5 — confirm the door aperture before glue-up
  • Edges eased and sealed; nylon washers at the bridge feet, no metal-on-metal squeaks
Do NOT: substitute a welded steel frame — DS-01 is joinery, and the rack bays are integrated into the ply pedestals, not hung off a frame. Do NOT let the desk touch the wall gypsum: it stands on resilient iso-pads under ALL feet with a gap, or it shorts the isolation. Do NOT power rack gear from anywhere but the DS-04 loom.

Work Surface & Display Well

Desk Top — DS-01

Specifications

ParameterValue
Finished height72–74 cm AFF — the datum for everything else on the desk
Material25 mm birch plywood (Baltic birch, B/BB grade)
Edge treatmentWalnut edge banding (solid wood, glued and sanded flush)
FinishMatte polyurethane, 3 coats, sanded between coats (220 grit)
Front edge profileSlight roundover (3 mm radius) for comfort
Surface underside≈70.5 cm — must clear the ≈66 cm tray top

DS-06 Recessed Tilted Display Well

The recess in this desk is not a control-surface pocket — it is the DS-06 display well at desk centre, holding a reclined panel 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.

Well ParameterValue
Tilt40–50° recline ONLY — 8–36° is the FORBIDDEN band; near-flat ≤7° also rejected
Panel24–27″ MATTE (anti-glare), OWNER-SUPPLIED — a gloss panel is a rejection
Bottom edgeat the 72–74 cm surface
Well pit≤4 cm below the surface top — any deeper fouls the DS-03 tray envelope
Top edge27″ panel lands 95–99 cm; HARD CAP ≤108 cm (below OW-1 sill 110)
Footprint25.7 cm at 40° / 21.6 cm at 50°; ≤28 cm allowance → keyboard zone 52 cm
Precision required: Cut and line the well with a CNC router or a template and flush-trim bit; test-fit the cradle before finishing. The installed recline is measured with a digital angle gauge, not eyeballed — 36° and 40° look identical and only one keeps the reflection out of the engineer’s ears. Anything in 8–36° is a REJECT: rebuild the cradle, do not shim it.
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.

Monitor Bridge

DS-05 — Raised Bridge

Specifications

ParameterValue
PositionRaised at the REAR of the carcass
Material25 mm birch plywood (matching desk surface)
SupportPly uprights into the carcass, nylon washers at the feet
MountVESA 100/200 bracket — the display itself is OWNER-SUPPLIED
Load ruleSpeaker-free and load-light — display only

The bridge lifts the owner display so the Genelecs aim past it, not through it. The speakers do not live here. [AC]

Do NOT put the monitors on the bridge. Per the H1r3 speaker rule, the 2× Genelec 8030C sit on their IsoAcoustics stands at the desk FRONT edge, baffle ≈25 cm off the partition, tweeters at 120 cm. At ≈25 cm the quarter-wave SBIR null lands ≈343 Hz — above Schroeder (253 Hz), where the room’s broadband panels and QRD have traction. Pushed back to the bridge (≈0.95 m) that null drops to ≈90 Hz, in the untreatable modal region. Never hard on the desk surface either.
OW-1 disclosure: a centred large display on the bridge sits exactly in the OW-1 band (sill 110 → head 160) and would block the engineer’s view into VO. Mitigation at shop drawing: offset the display EAST toward the D3 side and keep the west portion of OW-1 clear. Disclosed, not hidden.

Tray & Storage

DS-03 — 88-Key Pull-Out Tray

Specifications

ParameterValue
Tray width~150 cm (the full 170 − 2×10 aperture)
SlidersAccuride 3832EC-class full-extension, HEAVY-DUTY ≥45 kg/pair
Tray top≈66 cm — clears the ≈70.5 cm surface underside
TravelFULL extension; flush-parks under the work surface
ClearanceSlides ABOVE the DS-02 bays (rack top ≈45.6 cm)

An 88-key controller measures 136–146 cm, so it fits the ~150 cm tray with 4–14 cm margin — but only if the end panels stay ≤10 cm each. A 61-key controller on the desktop is a fallback, not a requirement, and fits the same tray with no change order.

Make-or-break detail: the sliders must be rated for a weighted 88-key controller and park it flush so the operator chair rolls free. Under-rated sliders sag under a weighted action and the tray stops closing.

Storage

Both pedestals are consumed by the DS-02 8U rack bays — this desk has no drawer schedule in the contractor package. Bulk storage for the facility is the ST-01 video storage cabinet (~120 × 60 × 200 cm, closed joinery, in the Video room), not the desk.

Do NOT add drawers into the pedestals without a shop-drawing check: a drawer box in a pedestal fouls the 8U bay, and a drawer under the surface fouls the DS-03 tray envelope. If the owner wants desk storage, it is a shop-drawing item priced separately — it is not in DS-01 as specified.

Equipment Layout on Desk

Equipment Positions

Everything in this table is OWNER-SUPPLIED (see AV Equipment) — it is not contractor scope and is not in the DS-01..DS-07 BOQ lines or the budget ladder. It is shown so the joiner knows what has to fit where.

Floor, beside deskDAW workstation towerFull-tower case does NOT fit an 8U bay; knee space stays clear for DS-03 tray hardware
Desk power is AT CAPACITY. The DS-04 6-way IG strip is fully allocated by design: display 1 + Genelec 2 + interface/rack 1 + workstation 1 = 5 of 6 used, 1 spare. No chargers on the desk spur (those live on the EL-06 station), and no daisy-chained strips, ever. Any additional device needs its own outlet plan — the Control room carries 10 counted ways under the H2f spare rule, so there is a real outlet for it.
Unscheduled gear — do not build to it. The SSL UF8, SSL UF1 and Mackie Big Knob Studio+ appeared on earlier revisions of this page but are in no equipment schedule and no BOQ line — not in AV Equipment, not in DS-01..DS-07, not in the owner-equipment appendix. A recessed control-surface pocket has therefore been removed from the work surface: the only recess is the DS-06 well. If these controllers are real, they need an equipment-schedule line and a fresh surface-allocation check before any pocket is routed — the well already occupies desk centre.

Cable Management

DS-01 spine + DS-04 loom

Cable-Management Spine

FeatureSpecification
LocationFull length of the REAR edge of the carcass
FunctionEvery desk run loomed, labelled and strain-relieved into it
Rear spine railTakes the DS-07 gas-arm clamp — never the monitor bridge

DS-04 Power / Data Loom

ElementSpecification
Outlet strip6-way isolated-ground (Legrand class) fed from the AV-01 spur
Data2× Neutrik etherCON feed-through
USB1× USB pass-through grommet
LabellingBOTH ends of EVERY run, to the cable run-schedule IDs
Cable discipline: keep mains and audio/data physically separated in the spine. Rack gear in the DS-02 bays powers from the DS-04 loom, never from a separate strip.
Data is at capacity too. The desk has exactly two etherCON feed-throughs, and the Control-room camera run (CAM-C, talkback TB-03) consumes the second one — so the desk is at capacity on data as well as on power. Any further desk data point is a new wall plate under the CN-03 discipline, not another desk feed-through.

The desk faces OW-1 (window local 87.6→167.6 against the desk’s 30→200), so the seated engineer’s sightline runs over the DS-06 well and through the window into VO.

Tight fit: at 170 cm the desk consumes the whole usable zone with only 3.5 cm to the D3 jamb. Swing D3 through its FULL arc at dry-set and confirm no contact with the desk, the extended DS-03 tray, or the chair. [HP]
Do NOT fix the desk before the dry-set sign-off. Everything after it is terminated and levelled in place — a 10 cm surprise here costs a rebuilt loom.

The budget ladder carries the desk and the ST-01 video storage cabinet ($450–850) as one line at $1,850–$3,800 [band corrected 2026-08 H2e]; the small uplift over the line-item sum is install and contingency. ST-01 is a Video-room cabinet, not part of this desk.

Correction — the previous figure on this page was wrong. This page carried ~$720, built from a steel-tube frame and a drawer set. That number never carried the rack rails, the heavy-duty Accuride tray sliders, the DS-04 loom, the VESA bracket, the DS-06 well cradle or the DS-07 gas-arm — and it priced a desk that is not the one being built. Quote against the DS bands above, not the old total.

Displays, monitors, controllers and the workstation are OWNER-SUPPLIED and are not in these bands.

After Installation in Room (dry-set, before fixing)

  • Desk set in the H1r3 local zone 30→200, facing OW-1; 3.5 cm clear of the D3 jamb
  • Desk level on its resilient iso-pads; no contact with the wall gypsum [AC]
  • DS-03 tray pulled FULLY out with the operator seated — no clash with the chair zone or couch line

  • Well recline measured with a digital angle gauge: reads 40–50°. Anything 8–36° is a REJECT — rebuild the cradle, do not shim it [AC]
  • Well panel top edge measured off finished floor: ≤108 cm; seated sightline through OW-1 (sill 110) clear over the well [AC]
  • Well panel is MATTE; with room lighting ON, no luminaire face reflected in the glass (else the fixture is inside the ~129 cm keep-out radius and MOVES) [AC]
  • Speaker positions marked: desk FRONT edge, baffle ≈25 cm off the partition, tweeters at 120 cm — listening triangle verified [AC]
  • DS-07 upper-display position marked: swung-aside arc or east offset; OW-1’s west portion proven clear
  • Written sign-off recorded — then loom and final fixing
Acceptance: the desk is accepted when every shop item passes, the dry-set fit is signed off in writing, and the four DS-06 acceptance criteria (tilt 40–50° measured · matte panel · top edge ≤108 cm · pit ≤4 cm) are each verified on site. The tilt is measured, not eyeballed: 36° and 40° look identical and only one of them keeps the reflection out of the engineer’s ears.
