![]() Other than for the superb quality of the projected image, I imagine these projectors will go entirely unnoticed in the classrooms and won’t demand any attention at all for a very long time.”Īdam Harvey, AV solution architect, was looking to achieve a similarly enhanced student experience at the University of Hertfordshire: “Our newly refurbished teaching spaces are brightly lit for maximum student motivation yet we need the teaching material to be easily readable from all angles. As a buying criteria the noise level wouldn’t normally be so noteworthy, we have come to expect a level of noise with projection, but with the P525UL it was notable by its absence! During the demonstration, we were impressed by the colour reproduction, the image was bright and the colours strong.īut what really struck a chord during the demo was how silent the projector was. Looking to future proof its visual assets during a refresh within 15 teaching spaces, Paul Wilson, learning environment technology services manager at Teesside University was impressed by the P525UL: “The impressively low 238W power consumption in eco mode helps significantly towards our cost reduction targets alongside not having to factor in filter cleaning and lamp replacements. The sealed engine not only improves the dustproof performance but also reduces the perceived noise of the fan, the innovation behind the silent operation. No other manufacturer can offer this unique advantage. With no filter to change, downtime is reduced, while engineer visits and the associated disruption of gaining access to the projector for filter cleaning are eliminated. Filter-less operation represents not only a technical achievement in projector design, it delivers significant reliability and operational expenditure benefits. With LCD technology, achieving a completely sealed optical engine and therefore no filter, presents a significant challenge. What’s more, a sealed light engine satisfies another end user desire - to reduce the need for maintenance and thus lower the TCO. Keeping the device cool is vital to support continuous long-life performance.īy placing radial LCD cooling fans (NEC Patent) inside a sealed engine, the noise generated by the fans becomes much less apparent. The major challenge to overcoming the noise level is the need for fans to cool the projector components including the LCD panels and the phosphor wheel. ![]() The super silent NEC P Series laser projectors bring a sense of calm to the meeting or learning space enabling teams to share ideas and collaborate more effectively. Microphones are often installed in the ceiling mount alongside the projector with obvious challenges around audibility, here, silent projection becomes essential. By delivering lectures in a live stream broadcast with access to recordings 24/7, universities are able to fit learning around student lifestyles. The student experience is all important in higher education and universities are exploring ways to support student preferences and working styles. ![]() In a setting where focused attention is important, in a meeting or seminar for instance, taking steps to create an environment conducive to support this is vital. This affects our concentration, disrupts collaboration and forces people to raise their voice. ![]() Noise from traditional projectors is intrusive and distracts from the content displayed on the screen. What’s so important about reducing noise?
