Corporate facilities continue to upgrade town hall spaces for hybrid meetings that mix live stage cameras, executive laptops, and remote Zoom or Teams feeds. The added demand for confidence monitors showing PiP windows forces AV teams to move beyond simple matrix switchers and basic scalers.
The Aquilon C4+ supplies twelve 4K60 inputs and four independent 4K outputs with up to eight mixing layers per output. In a typical 300-seat auditorium install, one unit takes HDMI and 12G-SDI from three PTZ cameras, two confidence displays, and a media server while still leaving headroom for a backup laptop feed. Output one drives the main LED wall at 3840x2160, output two feeds the confidence monitors at 1920x1080 with two PiP windows sized at 25 percent and positioned via the built-in layout presets.
Install economics shift when the C4+ replaces separate 4K scalers and a downstream keyer. A recent 12,000-square-foot headquarters project trimmed rack space by 4U and cut cable runs by roughly 180 feet because the single chassis handled both program and monitor paths. Labor hours dropped because the preset recall system allowed the programmer to store PiP positions and layer priorities ahead of load-in rather than building scenes on site.
Signal Flow and Operator Workflow Adjustments
Once the unit sits in the control rack, signal flow starts with EDID management on the inputs to lock every source at its native rate. Operators then use the front-panel or web UI to assign layers, set keying values for lower-third graphics, and link the confidence output to follow the main timeline. During rehearsal the AV tech can toggle between four stored layouts without touching the lighting console or camera shading controls, keeping the event flow predictable.
Technicians also report that the unit’s redundant power supply and hot-swap fan modules reduce service calls in spaces that run 60-plus events per quarter. Firmware updates arrive quarterly and can be staged during off hours, avoiding the need to pull the chassis for each new feature release.
Looking ahead, facilities that standardize on the Aquilon platform now plan to add NDI and SMPTE 2110 cards as corporate networks move to managed 10 GbE backbones. This path keeps the same control surface and preset library while expanding input counts for future multi-site town halls without a full hardware refresh.
AV managers also highlight the C4+’s real-time 12-bit processing and per-layer color correction, which maintain consistent branding when executive laptops output mismatched color spaces. During a recent quarterly earnings broadcast, the system simultaneously keyed three lower-thirds, a live Twitter crawl, and a full-screen sponsor slate while the main LED wall remained locked at 4K60. The operator recalled the entire scene from a single preset triggered by the room’s AMX system, eliminating the need for separate downstream keyers and reducing points of failure.
Training time has shortened as well. Because the web UI mirrors the front-panel layout, visiting technicians can dial in PiP sizes and transition rates without studying proprietary software. One integrator documented a drop from six hours of on-site programming to under ninety minutes once the preset library was standardized across three buildings.
With 48 Gb/s internal bandwidth still unused in most corporate events, the C4+ positions itself as a bridge to 8K future requirements without immediate chassis replacement. Facilities teams now treat the processor as core infrastructure rather than a single-event rental, shifting budget conversations from capex spikes to predictable maintenance cycles.
Installation and Commissioning Practices
During rack mounting integrators allocate 2U clearance above the C4+ chassis for airflow while confirming the dual redundant supplies draw 450 W under full 4K60 load. Input labeling follows a fixed matrix where PTZ cameras occupy slots 1-3 and executive laptops map to 9-12 for instant preset swaps via Crestron or AMX triggers.
Commissioning tests verify 12G-SDI lock times remain under two seconds during live source changes. Rear connectors accept custom-length HDMI and SDI runs limited to 30 feet to keep attenuation below 3 dB, with all EDID tables locked before load-in to prevent format renegotiation during the event.
