Post houses are combining color grading suites as ownership groups consolidate facilities to cut real estate overhead. This creates larger single-site operations where multiple Baselight or Resolve stations must access the same camera-original files and reference monitors without adding latency. Integrators sizing Adder INFINITY 4000 systems now treat the merged room count as one extended matrix rather than two separate ones.
The INFINITY 4000 transmitter-receiver pairs support uncompressed 4K60 4:4:4 over standard 10GbE links with under one-frame delay. When two former four-suite operations merge, the combined endpoint total often reaches 28–32 devices. A single INFINITY 4000 chassis tops out at 48 ports, yet installers still add a second unit once the design exceeds 36 active connections to leave headroom for client-supplied laptops and HDR preview monitors.
Network and Workflow Adjustments During Integration
Existing 1GbE drops must be replaced with Cat6a or fiber runs rated for 10GbE because each grading station now pulls simultaneous dual-link 4K feeds plus USB-HID control. Switch fabric costs rise quickly; a 48-port Arista 7050X4 plus the necessary SFP+ modules adds roughly $18,000 before labor. Integrators also reconfigure the Adder AIM management server to create separate user groups so colorists retain exclusive access to their calibrated displays while sharing storage ingest ports.
Power and cooling calculations shift as well. Each INFINITY 4000 receiver draws 18 W and runs warmer than older AdderLink units, requiring an extra 0.5 ton of HVAC capacity in the equipment room for every eight receivers added. Cable tray space becomes another constraint when pulling new fiber between the central machine room and the combined grading floor.
Forward planning now includes spare 40GbE uplink ports on the core switch so the same Adder fabric can accept 8K endpoints or remote grading nodes without a full rip-out in three years.
Redundant power supplies on each INFINITY 4000 chassis become essential once the merged facility exceeds 24 endpoints, because a single PSU failure would otherwise drop every grading station simultaneously. Installers therefore specify dual-corded receivers and place the two chassis on separate UPS circuits, adding another $4,200 to the bill of materials but preventing costly downtime during client reviews.
Signal integrity testing now includes simultaneous 12G-SDI and HDMI 2.0 loops feeding reference monitors in both original suites. Colorists report that the sub-frame latency remains imperceptible even when two remote directors join via the AIM server’s guest-viewer mode, provided the 10GbE backbone maintains under 150 µs jitter. This capability lets merged post houses market “any-suite, any-monitor” grading without relocating hardware.
Finally, documentation packages must be updated to reflect the single logical matrix. New Visio drawings show every transmitter port mapped to both local and remote receivers, while AIM audit logs capture which colorist accessed which camera-original files. These records satisfy insurance carriers concerned about multi-tenant access after consolidation and simplify future audits when additional suites are folded into the same Adder fabric.
Many consolidated post houses are now extending the INFINITY 4000 fabric to include archive-grade storage nodes and HDR laser projectors located in adjacent screening theaters. Because each additional 4K60 projector consumes two transmitter ports and requires its own EDID profile within the AIM server, installers routinely reserve four spare ports per chassis rather than the two previously allocated. This practice prevents last-minute hardware swaps when a director requests simultaneous 4K and 8K confidence monitoring during final color passes.
Budget models prepared for ownership groups show that the incremental cost of the second INFINITY 4000 chassis and associated 10GbE switch upgrades is typically recovered within 14 months through reduced real-estate expense and eliminated duplicate ingest workflows. Facilities that have completed the migration report a 22 % increase in billable suite hours because colorists can now move between any calibrated room without recabling or re-authenticating storage mounts.
Looking ahead, several operators are evaluating 25GbE uplinks between the Adder chassis and the core switch to accommodate uncompressed 8K60 or high-frame-rate HDR workflows expected within the next two product cycles. Until those links are activated, the existing 40GbE spare ports already provisioned on the Arista switches provide an orderly migration path without chassis replacement.
Staff training has emerged as a parallel workstream. Colorists accustomed to dedicated hardware now receive short sessions on the AIM web console so they can request temporary guest-viewer sessions for clients without calling engineering support. The same console generates automated compliance reports that satisfy both SOC-2 audits and insurance requirements for multi-tenant access control.
