Before Purchasing an LED Wall…

LED walls are increasingly being used in HoW worldwide as prices become more affordable. Once considered a tool for only the largest mega-churches with budgets to purchase them and the staff to operate them, LED walls are now within reach of smaller organizations with more mainstream budgets. Here we discuss three important aspects to consider before purchasing an LED wall.

Brightness

The color emanating directly from an LED is very vivid, and very high in contrast – many will say that content on an LED Video wall “really pops.” LED video walls have no problem competing with ambient room light, and they also coexist quite well with theatrical lighting.

Depending on the pixel pitch chosen, a single cabinet can have over 16,000 3-color LEDs. While conversion from Nits (the measure of light output often used for LED walls) to Lumens (the measure of reflected light used for projection) is not a direct process, since one involves area and another does not, even a modest 1200 Nit LED wall is significantly brighter than most single projectors are capable of. This is why in high ambient light situations, projectors are often “stacked” – two devices sending the same image to the same screen to meet minimum brightness requirements for the venue. By comparison, a 1200 Nit LED wall would actually be too bright in some more theatrical-style church lighting situations.

Tectonic Audio Labs Technical Video Series

In Extras, Industry News, Web Articles by tfwm

Tectonic Audio Labs has produced a 21-part technical video series explaining the function, performance and application of Distributed Mode Loudspeaker (DML) technology. Unlike traditional speaker systems that utilize pistonic cone and compression drives to produce audio, Tectonic speakers employ large format flat panel DML resonant mode devices to propagate audio.

“DMLs produce audio in a fundamentally different way than a typical loudspeaker does”, explains Tim Whitwell, physicist and DML expert. “This technology can seem quite counterintuitive to those not familiar with resonant mode devices.”

The Tectonic Technical Video Series condenses over three hours of conversations between Whitwell and transducer & loudspeaker systems engineer Marcelo Vercelli. Together they explore and explain DML technology. Each five minute video module covers a single topic in detail. Titles include:

  • How DMLs Work – Parts 1-4
  • DMLs vs. Pistonic Transducers
  • DML Feedback Resistance
  • DMLs In Reverberant Spaces
  • DML Stereo Imaging

“We set-up a video library on our web site that allows visitors to easily browse and sample topics of interest”, says Scott Garside, Marketing Director. “There is a wealth of information here that provides a fundamental understanding of resonant mode audio propagation. The function and benefits of DMLs are quite remarkable.”
