Dynamic Pairing is a special feature in Q-SYS Designer software that allows you to link a virtual peripheral device in your design to a new physical hardware device on your network, like an I/O-8 Flex or the new NV-32-H. This means you can build your Q-SYS design to include an I/O device that perhaps you … Read More
Most conventional cinema “screen channel” loudspeakers are designed to sit on a platform behind the cinema screen. The low frequency (LF) enclosure is made of heavy MDF panels to offer the best low frequency performance for the lowest cost. The horn section is supported by metal brackets and is mounted to the top of the LF … Read More
In a previous blog about loudspeaker sensitivity, we looked at two readily available woofers to see how different specifications and construction techniques resulted in different amounts of low frequency output capability. For this discussion, we will take a single woofer design and see how using 1, 2 or 4 woofers affects total output capability. Doubling … Read More
In this time of COVID-19, it’s wise to avoid touching any surface that others are also likely to be touching without first sanitizing it. Better still, avoid touching that surface at all; but this would seem to present a problem for touchscreen control devices, like the TSC Series controllers in our Q-SYS Ecosystem. But wait! … Read More
Honestly, it is likely that you already know this, but if you don’t, EASE is software that provides sound system designers a set of tools to help simulate, or model, the acoustics of a venue. Basically, it helps determine the best locations to install your loudspeakers to get the best sound coverage for your space. … Read More
In our previous blog post, Sensitivity Sensationalism, we looked at some incorrect assumptions often made around loudspeaker sensitivity and power ratings. We discussed the dangerous practice of publishing inflated specifications, including frequency range, power handling, impedance, and unspecified boundary loading conditions. And we promised a deep dive into the design of a Screen Channel Low … Read More
How I Learned to Stop Worrying and Love the Core Auditoriums with balconies can provide a significant challenge to the proper design and deployment of a cinema audio system. Generally, a 7.1 cinema auditorium is considered a single seating zone which is covered by multiple audio channels. When a balcony is introduced to an auditorium … Read More
In this third and final installment of our look at small rooms, we’ll focus on Q-SYS and how it can be used for multi-room systems, especially “cinema on demand” rooms in commercial multiplex sites. As before, let’s look at room sizes of about 10m, or 33 ft. in length. We’ll also assume the use of … Read More
Loudspeaker sensitivity and power ratings have become the primary specifications used to design sound systems in cinema. This practice and these specifications are accepted at face value and not often questioned. They make designing sound systems fairly easy and straightforward. However, they rely on many assumptions and some of them are simply not valid, at least … Read More
No one knows exactly what the “new normal” of cinema exhibition will look like. First, let’s get this out of the way: Coronavirus will not kill the global cinema exhibition industry. Changes are for certain, but cinema is here to stay. As has already been said by many industry observers – cinema has survived the … Read More
