the hockey hall of fame needed fresh projection as the old units in the tsn theatre and tim hortons theatre reached end of life. installers focused on keeping the 125 seat and 120 seat rooms operational while fitting new laser models into existing mounts and signal paths. m 4k15 installed in tsn theatre - courtesy manufacturer
rack space and heat load laser models run cooler than lamp units which cuts cooling demand in small equipment rooms. techs still had to check airflow paths around the new m 4k15 and 4k860-is because tight closets can trap dust and trip thermal sensors at 2am during long film loops. the crew added a 40 mm spacer plate under each chassis to restore the original 50 mm clearance to the side wall, a change that dropped measured intake temperature by 6 °c on the second day of operation.
cable paths and blend alignment three gs series units blend across the world of hockey zone. existing cable trays limited new runs so the crew reused some fiber paths and added only short hdmi extensions. field crews note that blend edges need recheck after any rack move because vibration from nearby exhibits shifts alignment over months. after the first weekend of full programming they discovered a 1.2-pixel vertical drift on the left edge; tightening the lock screws on the lens shift dials and adding a thin neoprene pad under the projector foot stopped further movement.
lens shift and throw distance adjustments none of the three exhibit projectors landed at the exact throw listed in the submittal drawings. the middle unit required a 180 mm upward shift plus a 4 % zoom reduction to hit the 5.8 m image width. rather than order new lenses the team used the built-in lens memory presets to store two positions, letting staff switch between the main show and an alternate 16:9 archival mode without touching the mounts again.
retrofit timing in live venues work happened around scheduled film screenings and interactive sessions. one practical step is to pre test projector settings on a spare machine with the same edid chain before pulling the old units. that avoids last minute edid fights when channel counts climb during peak visitor hours. the team also ran a 45-minute loop of the longest film file on the bench the night before swap day; the test exposed an intermittent hdcp 2.2 handshake that was fixed with a firmware roll on the matrix before any ceiling work began. applied electronics crews confirmed the projectors integrated with the existing control system once placement and settings were dialed in. final labor came down to careful rack re layout and one extra day for blend touch up rather than full rip and replace. after sign-off the hall reported zero service calls on the new units through the first three months, a stretch that included two consecutive sold-out documentary runs.
