ELK Products ELK-129 Computer Sound Card Interface
Overview
The ELK-129 is a compact 3LCD projector engineered for classrooms and conference rooms where bright, sharp imagery and simple setup matter. Rated at 3,600–5,000 ANSI lumens depending on resolution mode (XGA or WXGA), the unit delivers usable brightness in lit spaces without requiring full-room blackout. The 0.63" 3LCD optical block supports 4K@60Hz signal input, accepts standard HDMI with ARC audio pass-through, and includes built-in corner correction and keystone adjustment for fast alignment on irregular surfaces or ceilings.
Compatibility
The ELK-129 interfaces with any source device outputting HDMI or 4K signals—laptops, media players, document cameras, or switched infrastructure. The optional WiFi dongle enables wireless mirroring from Windows, Android, and macOS devices. HDMI ARC support means audio routes through the same cable, simplifying cable runs in retrofit or temporary installations. The XGA (1024×768, 4:3) and WXGA (1280×800, 16:10) modes accommodate legacy 4:3 content and modern 16:10 presentations without pillarbox artifacts.
Installation Notes
The unit weighs 3.1 kg and measures 345×99×261 mm (W×H×D), fitting standard ceiling mounts or short-throw cart deployments. Horizontal and vertical keystone correction handles ceiling offset and angled projection planes. Four-corner manual correction enables edge alignment on trapezoid walls or angled surfaces. The projector draws power via the supplied detachable AC cord and requires standard 110–240V mains input. Lamp life reaches 20,000 hours in Eco mode—approximately 6.8 years at 8 hours per day—reducing maintenance downtime compared to conventional models.
